No start puzzler
I have a late 2008 mac pro and it suddenly will not boot up.
I get the chime and then the spinning wheel with the apple and then it shuts off and cycles through that over and over.
If I try to boot from the cd that came with the machine or a Leopard install disk, I get a kernel panic.
It will boot into the hardware test, it runs but doesn't find any problems in either the regular or extended test. I even left that cycling overnight.
It will boot into single-user mode but the fsck finds no problems.
Pram resets but it will not boot into open firmware.
I have even started it in target disk mode, hooked it to another computer, booted that computer off the install disk and repaired permissions.
I have removed all possible combinations of RAM with no effect.
Lastly, I even installed Leopard on a hard drive on an identical computer and switched it into the non-working one.
I am at the end of my rope with this thing. It was working fine up until this happened last week. Any suggestions are welcome.
Have you tried resetting the SMC?

That's normal. It's only abnormal if it gets too hot to hold.

ThanX.JSP's are for use with J2EE web applications. Ther is nothing stopping you from using them to do a regular web site however.
Here is a good, Free, online course for J2EE programming.

You should have familliarity with Java programming, HTML, and XML before you try to learn J2EE.

I have what I believe is very a similar problem.
Only the MessageServer starts in sapmmc. The Dispatcher soon stops and I then get the message
"C:\SAP\NSP\DVEBMGS00\work>set DBNAME=NSP

in C:\SAP\NSP\DVEBMGS00\work\stderr0.
The best I can get is that the disp+work.EXE Dispatcher is "Running, Message Server connection, OK, Dialog Queue time: 0.00 sec" after starting in sapmmc but it stops after 1:15 with the above message.
Most grateful for any suggestions.
Edit : I now have instead of the above
C:\SAP\NSP\DVEBMGS00\work>findstr "ONLINE" adatmp
ONLINE
Database NSP successfully started !
but still the Dispatcher stops afer 1:15.
I now find the message that the system cannot find a file that I see is in fact present under the path given in the message:
ERROR => DlLoadLib: LoadLibrary(C:\SAP\NSP\SYS\exe\run\dbsdbslib.dll) Error 126 [dlnt.c 241]

which puzzles me. -
[SOLVED] Puzzled: Web site visible on network but not outside network
Edit: Ok, nevermind . . . somehow the problem has resolved itself. Perhaps my ISP was having a bad hair day or something.
I'm puzzled by this small problem I'm having. It is NOT a critical problem or anything, just something I'd like to solve.
I've installed the LAMP packages, set up a small MySQL database and made a very simple web interface for it. The web pages open fine on my main computer and all the other computers on our network, but it is not visible outside our network.
I am behind a router and I have forwarded port 80 to my local IP. I've set httpd: ALL, http: ALL and (finally) ALL: ALL: ACCEPT in /etc/hosts.
I got to thinking maybe my ISP (RoadRunner) is blocking port 80 requests to my home, so I changed the port to 9292 and forwarded that to my local IP. Still not visible from the outside.
I've tinkered with the /etc/httpd/conf/httpd.conf file (pasted in below) but still there is no outside connectivity, changing the listen settings and the server name settings. I can still access it fine from this side of the router. I've restarted the httpd service many times.
I've done all I can think to do to solve the issue. it is likely I am overlooking something very basic. Any help or ideas are appreciated. Below is my httpd.conf.

# configuration directives that give the server its instructions.

# ServerRoot: The top of the directory tree under which the server's

# Do not add a slash at the end of the directory path. If you point

Start and Stop Trigger using PXI-6120 and DigitalStartAndStopTrigger.vi not working :-(
Hello,
I've been trying for a while now to get my PXI unit to capture a waveform between a Start and Stop (Reference) Trigger using the NI example DigitalStartAndStopTrigger.vi downloaded from the NI website. However, whilst the start trigger and stop trigger seem to be working i.e. the VI runs and stops at the correct times there is never any data read from my DAQmx compatible PXI-6120 card. So I can see the VI is running around the aquisition loop but the Property Node AvailSampPerChan is always returning zero... this has me slightly puzzled. I thought this might just be a driver issue so I've updated my box to the following software versions (see below) and installed the latest drivers e.g. DCDNov07.exe (also from the NI site) but nothing has changed.
my software as of now.
Labview 7.1 (with the 7.1.1 upgrade applied)
Max 4.3.0.49152
DAQmx 8.6.0f12
Trad DAQ 7.4.4f7
before I updated I had the same problem but with the following versions:
Labview 7.1 (with the 7.1.1 upgrade applied)
Max 4.2.1.3001
DAQmx 8.5.0f5
Trad DAQ 6.9.3f4
So to cut a long story short I still have the same problem with the triggers... does anybody have any ideas what is going wrong?
To add insult to injury it the traditional DAQ example ai_start-stop_d-trig.vi was almost working correctly before I did the upgrade. It had the strange behaviour of capturing the AI0 channel but on the wrong edges (e.g. if I set Start on Rise and Stop on Fall it would do the opposite, Start on Fall and Stop on Rise).
I'm going to leave my box doing a mass compile over night but i'd really like it if someone could suggest a solution or point me in the right direction.
Many thanks,
MikeHi Graham
I'm out of the lab today but I'll try and answer your questions as best I can...
1) What are the values you have set for Buffer size, Rate, samples per read and post trigger Samples?
At the moment I have all the values (e.g. sample rate, buffer size etc) unchanged apart from the ones I mentioned in my previous post (see above). I have in the past played around with changing the buffer sizes and rates in the example VI but as this appeared to have no effect on the behaviour I now have them setup as in the download.
2) Does the program end after the stop trigger is implemented?
Yep, if I toggle the trigger line high then low I see the program exits the read loop and the VI stops running as expected.
3) Lastly can you give me the details of triggering method. Are you
using a digital train of users set digital pulses? how long is the
program running.I'm using the WriteDigChan.vi to manually toggle the first digital line of the PXI-6733 card which is wired directly to PFI0 of the PXI-6120 card. Generally, I just start the VI running and then toggle the line high, wait a couple of seconds and then toggle it low.
To me it all looks like it should be acquiring samples but as I said yesterday it just refuses to fill the buffer with any data (and hence no samples are read).
Any ideas? and thanks for you help,

LogMiner puzzle - CLOB datatype
Hello, everybody!
Sorry for the cross-post here and in "Database\SQL and PL/SQL" forum, but the problem I am trying to dig is somewhere between those two areas.
I need a bit of an advice whether the following behavior is wrong an requires SR to be initiated – or I am just missing something.
Setting:
- Oracle 11.2.0.3 Enterprise Edition 64-bit on Win 2008.
- Database is running in ARCHIVELOG mode with supplemental logging enabled
- DB_SECUREFILE=PERMITTED (so, by default LOBs will be created as BasicFiles - but I didn't notice any behavior difference comparing to SecureFile implementation)
Test #1. Initial discovery of a problem
1. Setup:
<li> I created a table MISHA_TEST that contains CLOB column
create table misha_test (a number primary key, b_cl CLOB)<li> I run anonymous block that would insert into this table WITHOUT referencing CLOB column
begin
insert into misha_test (a) values (1);
commit;
end;2. I looked at generated logs via the LogMiner and found the following entries in V$LOGMNG_CONTENTS:
SQL_REDO
set transaction read write;
insert into "MISHA_TEST"("A","B_CL") values ('1',EMPTY_CLOB());
set transaction read write;
commit;
update "MISHA_TEST" set "B_CL" = NULL where "A" = '1' and ROWID = 'AAAj90AAKAACfqnAAA';
commit;And here I am puzzled: why do we have two operations for a single insert – first write EMPTY_CLOB into B_CL and then update it to NULL? But I didn’t even touch the column B_CL! Seems very strange – why can’t we write NULL to B_CL from the very beginning instead of first creating a pointer and than destroying it.
Key question:
- why NULL value in CLOB column should be handled differently than NULL value in VARCHAR2 column?
Test #2. Quantification
Question:
- having LOB column in the table seems to cause an overhead of generating more logs. But could it be quantified?
Assumption:
- My understanding is that CLOBs defined with “storage in row enabled = true” (default) up to ~ 4k of size behave like Varchar2(4000) and only when the size goes above 4k we start using real LOB mechanisms.
Basic test:
1. Two tables:
<li> With CLOB:
create table misha_test_clob2 (a_nr number primary key, b_tx varchar2(4000), c_dt date, d_cl CLOB)<li>With VARCHAR2:
create table misha_test_clob (a_nr number primary key, b_tx varchar2(4000), c_dt date, d_cl VARCHAR2(4000))2. Switch logfile/Insert 1000 rows and populate only A_NR/Switch logfile
insert into misha_test_clob (a_nr)
select level
from dual
connect by level < 10013. Check sizes of generated logs:
<li>With CLOB – 689,664 bytes
<li>With Varchar2 – 509.440 (<b>or about 26% reduction</b>)
Summary:
<li>the overhead is real. It means that table with VARCHAR2 column is cheaper to maintain, even if you are not using that column. So adding LOB columns to a table "just in case" is a really bad idea.
<li>Having LOB columns in the table that has tons of INSERT operations is expensive.
Just to clarify a real business case - I have a table with some number of attributes, one attribute has CLOB datatype. Frequency of inserts in this table is pretty high, frequency of using CLOB column is pretty low (NOT NULL ~0.1%). But because of that CLOB column I generate a lot more LOG data than I need (about 30% extra). Seems like a real waste of time! For now I requested development team to split the table into two, but that's still a bandage.
So, does anybody care? Comments/suggestions are very welcome!
Thanks a lot!

Michael Rosenblum -
Hello,
this is a desperate call: I am at a conference with my MBP, (10.6.7, all updates done). I need Matlab for my presentation, which needs X11.
X11 (and XQuartz) decided that they won't start anymore: the icon bounces in the dock for a while, then sits there without the little light underneath, and X11 is "non responding".
The logs show something like this.
I have googled and searched: similar problems once in a while appear but no posted solution.
I tried:
1) reinstalling XQuartz (I would reinstall X11, but how? I do not have the disks with me, I am away!)
2) from an admin account
3) create a new account.
4) repair permissions.
5) reinstall the font update from Apple that was recently issued.
HELP PLEASE!!!

11-05-16 5:02:04 PM org.x.privileged_startx[20781] font_cache: DoneHere is the solution: there was nothing wrong with x11 per se!
The problem was that about 30 files in /usr/bin (like gzip, egrep, hexdump etc) had been hosed (they had 0 file size). The puzzling messages was due to the fact that startx uses hexdump, which was simply silently doing nothing (since it had 0 size!).
I do not know what or when these files were zeroed: I suspect a recent OSX update which did not complete and I had to forcefully reboot.
I have fixed it enough to work (copying those files from another mac), but who knows what else lurks beneath the surface of apparent serenity!
I am actually surprised that the whole system did not stop functioning completely.
MORALE: if something looks strange in the logs with x11 or other apps, check the file sizes in your /usr/bin, you may be surprised too! -
I have written the code to take a text file (from a command line argument) holding the information for the word find grid and also the file holding the words to be found in the grid. The whole find the two files and drop them into memory works all peachy keen but the rest of the program doesn't work for some oddball reason that I can't figure out (and the TAs are useless as usual). I dropped in print statements all over the world to see why it's not working but all I can see is that I hit the method SolvePuzzle and don't actually get any further than the print statement.
Just so you know, all of the methods in the program do work as I wrote them for another version of the same puzzle...it was just that I had to change the program to run with command line arguments instead of asking the user to input the file names. Please, can someone take a look at this monstrous mess and tell me how on earth I get the stupid thing to output correctly?

WulfYour problem is the duplicate declarations of rows/columns
class fields
private int rows, columns;
and in loadPuzzle()
int columns = oneLine.length( );//remove int
int rows = puzzleLines.size( );//ditto
the 'int' makes rows/columns local to loadPuzzle(), leaving the class fields rows/colums = 0
the for loops of solvePuzzle() are not executed because rows = 0
also, in loadPuzzle() you seem to have an extra readLine() at the top. This could be by design, but you will lose the first line
// get the row and columns
oneLine = wsFile.readLine();//<--------------

EMac Freezes in Normal Start Up - OK under Safe Boot 10.3.9 or 10.4.11
In helping a charter school get its eMacs back running, one of these eMacs [(ATI Graphics w/32Mb VRAM), 1.25GHz G4, 37GB HD, 1Gb RAM, and whose SN = G8429CDSQJ8] is displaying very unusual symptoms. It simply has to be software or a very weird RAM or VRAM memory issue, but I am mystified as to whose since I found no Firmware Updates at Apple or ATI. Here is the gory story.
I had replaced its battery and added a 1Gb DIMM (About This Mac and System Profiler show this is OK). I repaired the HD from a “Gray Restore DVD that was shipped with these eMacs” (got a “No Repairs Needed” from this) and its Permissions from the DVD set of 10.3.x system SW, and initially did an "archive and restore" installation. This had worked fine for all the other 10 eMacs as had going up to 2 Gb RAM.
On re-start the eMac froze and refused to eject Restore DVD. I hooked up a Firewire Cable to the ailing machine and ejected the Restore DVD after starting the ailing eMac in Target Mode. After this, I started up in Safe Boot and updated the 10.3.x Restored SW to 10.3.9 using Software Update ... things seemed fine. So, I started up in normal mode, opened System Preferences to Accounts to make sure the Student account was under agreed restrictions. As soon as the Authentication panel opened, the eMac froze, needing a Power Button shutdown … it kept doing this, and it behaved itself under Safe Boot after each freeze. I installed YASU (from a CD in Safe Boot and have used for years on my home PMMD, dual 1Ghz G4, 10.4.11), which I understand is simply a group of Unix scripts under a nice GUI and had it do all the system and web browser tasks (i.e. crons, permissions, prebinding, swap filesetc) but saved the logs and their archives.
We were upgrading all the eMacs System SW to Os 10.4.11 (starting from a 10.4.3 "Black X" commercial system disk … so from a Safe Boot, I loaded the 10.4.3 DVD, started up from it, and did an Erase and Install, so all the SW on the drive is Apple’s own. PRAM was reset and amazingly, on this re-start, this eMac froze a few seconds after a App’s window opened. From a new Safe Boot, Software Update took me to 10.4.11 (I refused to allow Safari, iTunes and Quick Time update until it had also updated all the other security and Java (9 Javas of these in numerical order from SUD).
Under Safe Boot, I found I can open as many as 10 Apps or Utilities, flip between the windows … nothing wrong. After some thought, I used Activity Monitor, Disk Utility (to perform “Erase Free Space, 7X” and with Screen Saver’s Flurry at maximum in the Choice window, and this places the processor use at almost 100% (~70-75% user + ~20% system) … but this does not test much of the memory (couldn’t figure out how to do this). I kept things going for over 7 hours while randomly using Safari or Text Edit. But as soon as a Normal Restart is done and a second window opens (even Activity Monitor’s little floater), it freezes again.
The Web is full of symptoms that usually blame memory, but it seems hard to believe that the 1Gb DIMM would “know” when the system is booted Normal vs Safe. So, tonight, I am going to run Rember (v. o.2b) that I dragged off my PMMD … an have used it under 10.4.11 over the years.
BTW, contents of Trash after two (2) hard freezes are always the same system files [annex_aux, annex.db, filetoken.db, fonts.db, and qdfams.db]. The mention of “fonts.db” seems to suggest a font problem, but why … all are fresh 10.4.3 stuff.
It’s my understanding that Safe Boot allows ONLY Apple extensions and Apps to load and this is why it seems to me that the problem must be SW … somehow, somewhere.
Is there a utility that can list third party components? Does this make sense? In looking into the Preferences and Application Support there are Adobe, Macromedia prefs, fonts … which I assume came in w/ Safari since I have not added any 3rd party programs other than YASU, who tells you truthfully where its stuff is loaded
When back at the school, I plan to swap out 1Gb RAM DIMMs and/or replace the old 256Mb DIMM that was original. Also, plan to go back to the Restore Software DVDs (10.3.4 since these have more Apps that are needed): Erase (Zero Out Deleted Files) and Install to rebuild a “virgin” set of 10.3 after restarting. Then Check to see if Safe Boot is stable BEFORE trying to update to 10.4.11 (via 10.4.3 Black X).
However, if this does not make sense, I would be grateful for readers pointing out my errors and/or flawed plans.Hi Cosmic (and, per my Southern US heritage, hope yawl are doin fine down under),
Firstly, thank you hugely for guiding me through this eMac puzzle. Your insight that under Safe Boot the ATI video extensions are turned off now has the symptoms I see matching a cause.
Last evening, I did an Erase (Zero out the HD, 1 pass) and a virgin , custom install from the eMac Media DVD that came with the machine; this took the system to Os 10.3.6, and it seemed to let me open more windows than two(2) for several passes, but it still froze, these times leaving no recovered files as a trail.
I decided to use only Apple’s Software Update, under Safe Boot, to sequentially load only system or Java UDs and not let Safari or any iApp stuff bring in foreign SW components(tis strategy caused by finding, last evening, strange troubles with the Font book not validating any font and it displaying most of these incorrectly. This font finding kept me thinking SW had to be the problem instead of heeding your and Alan Jones experience …
All well and good, and when I got to 10.3.9 with all the Java and Security Uds, I could open as many as 4 Apps, but the killer was always testing the “Flurry” screen saver … lots of video here. Yet in Safe Boot, I could open all the Apps in the folder and randomly switch between them with no issues.
Lot of driving chores today kept me from seeing your second reply till late this afternoon, but as I drove I remembered that on my now ancient Power Mac Mirror Door, 2x1Ghz, one of my partitions had 10.3.9 loaded with free Unix scientific SW and Xbench 1.1.3 and Cinebench 2003, both of which test video cards, etc. So, I loaded and made DVDs of these testing apps after running them on the PMMD in the 10.3 partition as well as my normal 10.4.11 main drive. Got them over on the eMac, checked to make sure its fonts were OK, ran the tests under Safe Boot, then saw immediate freezes under Normal Boots, and finally, logged into the Apple site and read your reasoning. Bingo!
I again checked the caps I could see and they matched your ID of them, still, even with a machinists mirror could not see the ones further in … called the school marm and told her we should consider this eM as nearly dead, use its internal organs (HD, RAM, ATA drive) and externals (Keyboards, cables) in our organ donor program. She’s agreed, so it’s a done deal.
So, tomorrow I’ll satisfy my curiosity and do the surgery to remove the innards and see if there is evidence of the caps … sure there will be. BTW, I made my living, till a good severance package induced early retirement , as a PhD level Materials Scientist/Elec Engineer (mostly in chip level packaging and several forays into flat panel electronic displays (LCDs and OLEDS(Orgainc Light Emitting Diodes)). As I looked at the circuit board, these electrolytics seem to be surface mounted, an unusual design even for its day, and I cannot imagine any “shade tree” electrician having much success trying to replace them.
Again, a thank you for your insight. I’ll just have to owe you a beer since I’m doubtful you would get one I’d drop along the seashore. Take good care … and without checking a map, I hope Brisbane is not being flooded.

An iTunes Library Transfer Puzzle...Help!
Okay, let me try to be as clear as possible...
I keep my iTunes library on an external firewire drive.
I'm preparing to transfer all operations, including iTunes, to my new Macbook (from my old eMac)
Prepping for this move, I noticed that at some point imported music stopped going to my external drive and started going to my eMac drive.
So now my iTunes library is split between my eMac and an external firewire drive.
NOW FOR THE PUZZLE:
I want to transfer all the files from the eMac to their rightful home on the external drive.
Is there a simple way to move all these files at once (about 17 GB worth) so that the iTunes browser and my playlists will know to look for the songs on the external drive not the eMac?
Once everything is on the external drive as it should be, I plan to transfer the whole library to the iTunes browser on my Macbook.
My big fear is that the playlists will get screwed up (playlists consist of songs now on the eMac AND on the external drive).
Anyone out there able to help me sort this out?
Thanks a bunch.

Welcome to Discussions.
Prepping for this move, I noticed that at some
point imported music stopped going to my external
drive and started going to my eMac drive.
This might have happened when running iTunes with the
external drive not yet mounted/attached.
iTunes has to have a folder to store the next ripped
CD and will reset the 'iTunes Music folder location'
to the default location (on your internal disk) if it
doesn't find your 'iTunes Music' folder.
I want to transfer all the files from the eMac to
their rightful home on the external drive.
Set the 'iTunes Music folder location'
(Preferences>Advanced>General) to the folder
containing your music on the external disk.
Then choose 'Consolidate Library...' from the
Advanced menu in the menubar.
This will copy all music which is not already there,
to the external disk.
After that is done, you can delete the 'iTunes Music'
folder on the eMac.
Note: only delete the 'iTunes Music' folder inside
the 'iTunes' folder. Don't delete the library files.
Once everything is on the external drive as it
should be, I plan to transfer the whole library to
the iTunes browser on my Macbook.
Copy the 'iTunes Library' file (in
/Users/Username/Music/iTunes) to the external disk.
Attach the external disk to the MacBook.
Copy the 'iTunes Library' file from the external disk
to /Users/Username/Music/iTunes on the MacBook.
Run iTunes on the MacBook. All playlists and songs
should be there.
To transfer the music from the external to the
MacBook, read the detailed instructions in: iTunes: Moving your iTunes
Music folder
In short that would mean for your situation:
Reset the 'iTunes Music folder location'
Consolidate library
At the end, all songs and playlists will be on the
MacBook.
More information about the library files can be found
here: What are the iTunes library
files?
Hope this helps.

Screen does not turn on after start up, but after standby on Satellite M100
Hi,
I have quite some experience with computers and laptops, but this problem exhausted all my knowledge.
My girlfriend has a Toshiba Satellite M100, PSMA1E. It runs Windows XP, currently on SP3.
The laptop always had shutdown/stand bye issues. It would go on stand bye and the screen would not come back. She usually would turn it off manually (holding the power button) and turn it on again.
Same thing happened last week, but with me. I turned it off holding the power button but when I turned it back on the screen was completely black. After a few attempts I realized that everything was working; I could hear XP booting and the usual sound files but there was no way I could get the screen working.
The strangest thing is that the CMOS/BIOS screen, the first one with the Toshiba logo, also does not show up. If it was a OS problem I thought I would be able to access the BIOS at least, but that doesn't work. Fn+F5 also doesn't work.
Then something even stranger happened. I was turning it on and off with keyboard shortcuts and I realized that if I put it on stand bye using shortcuts and then turn it back on the screen turns on perfectly fine (there is some resolution adjustment cause icons are out of place, but it works perfectly well).
From that on I tried everything I know. BIOS update, all Windows XP updates, all Toshiba QuickFix, cleaning the registry with different tools, uninstalling and reinstalling the video driver (ATI Radeon X1400), HotKeys utility, Power Saver Utility, Toshiba Hardware Tools, looking at start up programs, services, everything I could possibly think off.
What really puzzles me is that the Toshiba start up screen won't show up. I can't access the BIOS, but I tried restoring BIOS standard values through Toshiba Hardware Tools. It didn't work. I don't even know if reinstalling XP will work because every time I turn it on it's all black and I need to do the stand bye/turn back on trick.
When I plugged it on a external monitor I could see the whole start up process (BIOS initial screen and Windows). I then tried to access the display configuration of the video driver but it would only show the external monitor. It would only detect the laptop screen after a stand bye/turn back on, and then it worked perfectly well: two simultaneous screens, extended screen, everything. Ah, changing the BIOS from Auto-Select to LCD+external monitor also does not work.
I'm really puzzled here and I can't figure this one out. I really don't think it's a hardware issue, because the screen works 100% after the stand bye. I guess XP is making something during shut down that completely 'shuts down' my screen, even after boot, and then I can only turn it on with the stand bye thing.
Any help would be really appreciated!
Best,Hi mate,
that whole story sounds really weirdo since after reading all this and knowing that youve tried almost everything doesnt makes it better.. :/
Usually I would say: update your BIOS, but you already updated everything. This problem could be BIOS related since the initialization of the hardware after a standby is controlled by the chipset trough the BIOS.
I guess it could also be something with the background light of the LCD screen (failed initialization after waking up), you can check this by reproducing the situation with the black screen and holding some light near the screen. If you can see some schemes on the screen (something like desktop, etc..) then it could be the background lighting. In such case try to reinstall the operating system and update all installed drivers to the newest version (yes I know, sounds like more pain).
Otherwise, click [HERE|http://eu.computers.toshiba-europe.com/cgi-bin/ToshibaCSG/generic_content.jsp?service=EU&ID=ASP_SUPPORT], find the nearest authorized service partner in your country, contact them and ask them for a hardwarecheckup. Maybe its really a hardware related issue..

Puzzler - Is there a way to detect when an external headphone or speaker is plugged in?
I have a puzzler, and my initial question is simply, is there a way to see via Windows if/when an external headphone or microphone is plugged in, or is that all an electrical circuit independent of the OS?
Background: (not necessarily the question I'm asking, but providing anyway):
The background is this: Dozens, Hundreds, I think Thousands of owners of Toshiba Satellite owners with Conexant sound devices (including myself) the world over have this problem where the sound stops working about 1 to 2 minutes into playing non-stop
sounds/music/videos. In spite of all the experts telling these poor people to run a system restore and wipe out the past years of files and everything on their computer, the problem prevails no matter what. Some have even installed Linux, and the
problem persists. To me, it seems that the problem doesn't occur if the only sounds are the occasional bing or bong from a system warning, it seems to fail after 1 to 2 minutes of continuous play (but this particular observation is mine only, nobody else has
taken the time to point that out).
A few have claimed success via blowing the jacks out with compressed air, but that's not repeatable universally. Most people end up keeping external speakers plugged in permanently. In other words, it seems a lot like a hardware problem; However,
{edit 3}, my addition of "Edit 2" below makes it seem less like hardware.
One interesting thing: Headphones/speakers work permanently, there's no problem. More curiously, when the sound goes out, plugging any form of headphone/microphone jack into
EITHER the headphone
OR the microphone jack turns the sound back on too. This includes male-to-male extension cable with nothing installed. If nothing is on the other end, the sound will go out
again shortly, but jiggling or removing the male to male turns it back on.
EDIT 2: When the sound goes out, another way to get it back: From system tray, right click the speaker item and choose SOUNDS. The virtual VU meter shows that audio is playing (in tandem with the song, etc.), and is still showing audio
playing. The tabs available are Playback, Recording, Sounds, and Communications. When the sound does stop (assuming I was watching Playback), I click the Recording tab (just the tab header), and sound starts again.
P.S. What's the difference between "High Definition Audio Controller" under System Devices, and "Conexant SmartAudio HD" under "Sound, Video, and Game Controllers", in Device Manager? The "conexant smartaudio hd"
points to the latest Conexant driver, the "High Definition Audio Controller" points to a default windows driver. Just curious
I've Binged this extensively: Toshiba doesn't acknowledge the problem and nobody has fully solved the issue. I'm just curiously trying a few things myself, and I'm not sure if there's a way for the system to tell me an external mic/speaker has been
plugged in.
So to recap: My main question, can I detect when the computer thinks a headphone or microphone is plugged in? (My theory, if I can prove that the computer THINKS something is plugged in, it's a start).
Only secondarily, if anyone's interested, feel free to suggest ideas (here's what dozens of other posts have disproven: System restore; windows reinstall; outdated sound driver; outdated video driver; remove and re-detect sound and device via device manager;
malware; BIOS upgrade; Flash and/or the Flash/Firefox/Hardware Acceleration issue (problem happens with MP3, Flash, WMA, HTML5, Games, everything).
Thanks in advance!
EDIT: One person (theirs was under warranty, mine's not) ended up getting a new motherboard & speaker via Toshiba warranty, diagnosis ""machine intermittent no sound due to PCB faulty". I'm still interested in troubleshooting,
though. Link:
One lucky person, who got their motherboard replaced (they were under warranty, most of us aren't)Hi,
If there are any headphone or speaker plugged in and detected, it will show in audio device manager console.
Type mmsys.cpl in Run, it will open Sound console.
Have you tried Hardware and Sound troubleshooter?
