Possible fix for no audio & grayed-out volume control

Hi, I just thought I'd post this fix I found for my Mac Mini losing audio and also having the volume control grayed-out as if permanently muted.
I have had this problem a couple of times on my Intel 2 GHz Core 2 Duo Mac Mini. I have tried some of the software solutions found on the web such as zapping PRAM, deleting certain Plists, etc. But in my experience the fix that has worked is to open the Mac Mini and unseat and then reseat the orange Foxconn ribbon audio cable where it connects from the Mini's audio board to what I assume is the main circuit board. Then when you reassemble and turn on your Mac, audio will be back.
My theory is that unplugging and re-plugging USB and audio cables on the back of the Mini near the audio board eventually loosens the internal ribbon cable and causes the audio to stop working. My latest attempt at a permanent solution is to have USB and analog 2.5mm stereo audio 'extender' cables plugged in on the back of my Mini, which loop forwards over the top of the Mini where they are all taped down securely. This allows me to plug and unplug cables without ever disturbing the actual USB and audio ports on the back of the Mini. I am hoping this will help avoid the lost audio & grayed-out volume control problem in the future since the connection of the internal audio ribbon cable is less likely to be disturbed. It is a somewhat ugly solution but seems to be working so far. I'll post later on if the volume control gets grayed out again even with these measures.

Not on mac though

Possible fix for errors 11503 and 50

Here's a possible fix for Error 11503 and for error 50.
It worked for me and hopefully it will work for you.
I believe this error is caused by the incomplete downloading of either an update to an app. In my case it was caused by closing the lid on my laptop when I was downloading app updates on a very slow internet connection in a hotel.
Anyway, here is what I did that fixed it completely.
Close iTunes.
Go to this folder : /iTunes/Mobile Applications/Downloads
You'll find tmp files there. Drag them out of this folder to a temporary folder on your desktop. The Downloads folder should now be empty.
Restart iTunes.
All should be fine.
If it is, delete the desktop folder with all the temp files.
If it's not, then I can't help further, but that's what worked for me.

Several possible causes from the info you gave
Battery level low - recharge it for at least 4 hours till the full charge sign displays (2 prong icon instead of lightning icon).
Time to Reset the iPod - Press the Menu and center Button for about 10 secs till the Apple logo comes ON, then let go of the buttons.
your hardisk is starting to give problems, hence the skipping and some song refuse to play. - Do a disk diagnostic - follow this post by tt2.
https://discussions.apple.com/message/17028567#17028567
If you have updated any sofware application in Windows, then follow this Apple support procedure
http://support.apple.com/kb/TS1539
Most likely you have to do all, as the iPod hardisk filesystem would have been corrupted, or else the iPod Reset would bring it to normal operation.
Good Luck!

Possible fix for OS X 10.5.7, losing connection after sleep, restart

Possible fix for OS X 10.5.7, Airport, losing connection after sleep, restart, or cold reboot.
Issue: (For OS X 10.5.7 on iMac5,1, Intel Core 2 Duo)
=============================================
- After sleep, restart, cold reboot, even though cannot connect to Internet, but the AirPort bars are still full, as if connected.
- Losing Internet connection after sleep, restart, cold reboot.
Possible Fix:
1.Open Network Preference, click on the Location drop down list > Edit Location... > click on the wheel button > Duplicate Location.
a)Select this newly setup location; Use Diagnostic button to connect to the internet. Select Network or enter WEP password if necessary.
b)Test to make sure you can connect to a web page.
c)Go to sleep & wake up.
d)This time, the Airport bar will start to show correctly. Before, it will always be full even when not connected. Now there will be no bars or grey out when not connected.
2.On the left hand side of the Network Preference Window, there is a list of services, such as Airport, build-in ethernet, built-in FireWire, bluetooth, etc.
a)Click on the wheel button on the bottom of the service list; select Set Service Order...; move Airport to the top of the list.
b)Delete any services which you are sure that you are not going to use, such as Bluetooth, etc.
3.Pick one of the locations mentioned in #1, and make it sure it is connected. If not, use Diagnostic button. If you have to select Network or enter WEP password to connect, make it so.
a)Check to make sure you can connect to a web page.
4.Go to sleep & wake up. The Airport bar should be filled up quickly. Try to connect to a web page.
5.Restart computer. Test a web page.
6.Shut down & Start computer. Test a web page.
7.When everything is working fine, you can delete the extra location that you created in step #1.
8.Click the lock on the left lower corner of the Network Preference window to safeguard the setting.

If my assessment is correct, the LIDE 200 driver is version 14.8.1 and dated 26-Sep-2008. It is possible that the driver will not work with the latest version of OSX. I would advise that you contact Canon and ask them the question.
(Removed link because of the way Flash drives the Canon site).
It is not uncommon (though irritating) that devices no longer work when an OS is upgraded. One has to ask the question if (or why) the driver was not written in such a way as to be OS version independent.
Chris
I spoke to Canon over here in Australia. Not helpful at all. In fact they were about as useful as an ashtray on on motorcycle. Having said that the tech seemed to think that there would be an update soon. But that is assuming that Canon are aware that there is a problem with that Scanner under OS X 10.5.7.

Possible fix for CPU temp problem found.

Well, one day I decided to take the heatsink off of the nForce3 chip and put some good ol' Arctic Silver thermal compound on there. I figured it might help with overclocking and whatnot. When I took it off, look what I found(!):
Imagine my surprise! Why did they even bother? Ridiculous. After removing their mistake, I put some Arctic Silver on there and re-attached the MSI heatsink (someday I'll probably buy a much better one for it). I've noticed after a couple of days (it takes a little while for the thermal compound to set in) that the CPU temp doesn't appear to fluctuate wildly anymore. Before I was getting crazy jumps from 45C to 65C, but now it hovers around 45C-47C idle and a little over 50C stressed. I've also noticed that my overclocks are a bit more stable now too. For those of you wondering, I'm using BIOS v1.1 at the moment (haven't tried v1.42 yet).
Can anyone confirm these findings? Maybe something else I did fixed my CPU temp issue (I do fiddle with the BIOS quite a bit). My guess is that the nForce3 has a part in determining/reporting the CPU temperature.
I hope this actually is a fix for some of you out there, but don't get your hopes up too high until at least one other person can confirm my theory.

It's very easy to remove the MSI plate. Using a pair of needle-nose pliers pinch the fins on the heat sink on one side together (one at the top, one at the bottom). You don't have to do it too much and be careful. This provides enough slack for the plate to drop out with some slight assistance. Well, that's how I did mine.
I then attached a 40mm fan by screwing into the gaps between the two fins. Only on the one side mind (so 2 screws in total). It holds the fan fine, no rattling.
I have some Artic Silver adhesive and I did consider leaving the MSI plate in place and fixing the fan to it. But I wasn't sure how secure it would be. Plus the plate rattles already, imagine how it would behave with a fan stuck to it.
Unfortunately, I forgot to make a note of the NB temperature before I did it. And I can't for the life of me remember what it was. So I can't say, for sure, how it has effected the temperature. I'm sure it has though.
I suppose it's easy enough to disconnect the fan to find out. I might try that later...
Running at 230x10 (stock = 200x10), MBM reports:
Case = 37C
CPU = 35C
Sensor 3 = 49C
The sensors are labelled by MBM, so I am assuming they respond to the correct items, ie the CPU temp is actually the CPU temp.
This is after a hour or so with Azureus running, mIRC open, a couple of IE windows and SETI running at ~97% CPU
When I take the side off to disconnect the fan again, I will take a picture.

Possible Fix for Printing Problems in Leopard

I got this information from Mac OS X Leopard Edition book by David Pogue. Here's his possible fix for printing problems in Leopard...Open web browser and enter this address http://127.0.0.1:631. You'll find youself at a secret "front end" for CUPS (Common UNIX Printer System), the underlying printing technology for Mac OS X 10.5. This trick lets your Mac communicate with a huge array of older printers that dopn't yet have Mac OS X drivers. Using this administration screen, you can print a test page, stop your printer in its tracks, manage your networked printers and print jobs, and more–a very slick trick. Haven't tried it yet...anyone who does let me know how it worked!

If you literally "checked" them, meaning the checkboxes, that only affects their visibility. To remove them, select one and then click on the "minus" part of the "plus minus" at lower left.
Doug

Why is the check box for remember passwords grayed out? It used to work now it won't save them.

Why is the check box for remember passwords grayed out? It used to work now it won't save them.

It could be because you have Firefox set to not remember any history. Did you do that intentionally? It is set in the Options dialog:
"3-bar" menu button (or Tools menu) > Options > Privacy
Perhaps it would work if you choose "Use custom settings for history" and just turn off the specific things you want to turn off.
Any luck?

Fix for Missing Audio Device in WinXP S

My sound card disappeared from the Sounds and Audio Devices Properties panel. I tried cleansweeping and reinstalling to no effect. I could watch my card disappear from the panel as Windows went through startup after I reinstalled it. My card , a Sound Blaster Li've!, was listed under the hardware tab but the drivers were listed as "Driver installed but not started". Creative Diagnostics said I passed the hardware detection test but failed the driver tests. I am using the drivers from the Li'veDrvUni-Pack(ENG) version .0.0..
I found this fix after searching with Google. The site is www.annoyances.org/exec/forum/winxpt/t06642744. It resolved my problem. I did use DH Driver Cleaner Pro to remove any Creative drivers. You need to know that the hardware scan and reinstall in step 6 can take several minutes. I also removed hidden copies of my Creative devices in step 5. The revealed hidden devices have greyed icons next to them.
Sincerely,
Weasel
re: sound device errorThursday, April 2, 2005 at 6:02 amPosted by Ven <FONT size=-2>(<I> messages posted</I>)
RE>Hello to all,
I got much useful information from this topic, but none of them resolved my sound
problem. I use Windows XP SP2 on an Asus V7V8X and a Creative SB Audigy. I also tried
removing the SB card and enabling the built in VIA AC 97 without success.
Then I tried removing and adding back the Plug and Play Software Device Enumerator
as you suggested without success.
Then I went further reinstalling some of the kernel sound drivers and that resolved
the issue in my case so I describe my ste
ps.
First I suggest everyone to create a System Restore point to have something to return
in case of something goes wrong. You can boot XP to safe mode by pressing F8 at the
beginning of the Windows startup and select Safe Mode if the system doesn?t start
in normal mode and use System Restore there to go back to the working configuration.
Then try these steps only if the others mentioned here don?t help. I had everything
ok in Device Manager and every driver was running that should, compared to an other
working system, but the symptom was that there was no sound coming out from the sound
card. Everything was OK in the Device Manager, but in the Sounds and Audio Devices
Control Panel there was only the Voice recording option on the Voice tab, and the
MIDI music playback (without the sound card being in the list) on the Audio tab acti've.
The others like Voice playback, Sound playback, Sound recording and everything on
the Volume tab was grayed out.
. Create the restore point.
2. On the System Properties panel, Advanced tab, Environment Variables button, under
the User variables click New and create a variable named devmgr_show_nonpresent_devices
with the value of .
3. Open the Device Manager and select Show hidden devices from the View menu.
4. Under the Sound, video and game controllers group, find your sound card(s) and
disable it/them (don?t need to uninstall).
5. Then uninstall the following devices:
- Microsoft Kernel Audio Splitter
- Microsoft Kernel System Audio Device
- Microsoft Kernel Wave Audio Mixer
- Microsoft WINMM WDM Audio Compatibility Driver
6. Select Scan for hardware changes from the Action menu. Now the system should redetect
and reinstall the deleted devices automatically. You may get non signed driver warnings,
click continue.
7. Enable the devices you disabled in step 4. You may need to restart the computer.
The problem should be disappeared, you should be able to play sounds.
Good luck!
Ven
</PRE>

Hi
You should check if the microphone has not been disabled.
Go to control panel -> sound -> recording tab
There you should make a right click and should enable the both options called show hidden devices and show disabled devices.
Now you should see 2 microphone entries; one internal mic and second should belong to the external mic jack.
If you want to use the internal mic then mark it as default device.
Cheers

Asmca has grayed out Volumes and ASM Cluster File Systems 11.2.0.3

I've got a two node cluster which is up and running with the latest 11.2.0.3 grid install on Oracle Linux 6.3
I need to get a shared storage location I can use for File I/O testing, ASM looks like the solution with an ASM Cluster File System.
When I run asmca I do not have the ability to create these volumes or file systems as they are Grayed out.
I found some instructions on how to get it to work, and they said to use acfsload to start up the required daemons:
[root@oracleA bin]# ./acfsload start -s
ACFS-9459: ADVM/ACFS is not supported on this OS version: '2.6.39-300.17.3.el6uek.x86_64'
I installed Patches: 13146560, 14596051 - Which I thought would fix the problem. Rebooted after successfully applying the patches, but asmca still shows them greyed out
and not supported on this OS error persists.
I see some posts online saying to edit osds_acfslib.pm and update it to allow for the supported ORACLE version
Right now it shows: ($release =~ /^oraclelinux-release/))) # Oracle Linux
under /etc it only has oracle-release - could that have something to do with it not passing the check?
uname -r
2.6.39-300.17.3.el6uek.x86_64
From what I can tell this kernal should support asm..
Any help in getting these shared storage asm disks setup would be very helpful, oracleasm creates them and sees them fine for databases. Thanks.

Turns out the Kernel version 2.6.39 does not have support for the ASM Drivers for the ACFS mounting.
I'm going to have to use Oracle Linux 6.2 (instead of Oracle Linux 6.3) and rebuild my RAC to get a supported version of the drivers -> Kernel version 2.6.32

Audio Grayed Out

I can't figure out what the issue is what my audio. I currently have it running through a system via HDMI. I've had it this way for a few months now. Today I came home and my audio wasnt working and it is grayed out.
I option clicked it and selected "internal mic" and that helped as audio is now coming out of the mac mini itself.
I'm just not sure how to fix it so that it will come out of my system again. Any ideas?

Hello,
Long shot, but...
Open Audio Midi Setup in Applications>Utilities, see the input & output options & KHz setting there, some things will change it for their own use, then not set it back.

Video/ audio grayed out

Hi,
The last time I was able to check this I could Video in iChat 5 to AIM 7.2.x running in XP behind the same Modem/router combined device.

Wireless Problems: Observations/Possible Fix for Some (No Guarantees)

Hi All:
I have been following our wireless problem threads. To a large extent, they revolve around lost connections, weak signals, etc. On my machine, I previously noticed what appeared to be wide fluctuations in signal strength, although I could almost always pick up one distant network that has to be at least 125' away regardless of my apparent signal strength. Also, I never lost my connection. I also have noticed that my Windows notebooks pick up more networks than my MBP, even though some must be farther away than 125'.
Recently, I had to reinstall all my software. Once resolved I'll explain why and what to look out for. Anyway, before the reinstall, I had done all updates. When I reinstalled, I also did all updates. The bottom line is that I have not seen the wide fluctuations in signal strength since reinstalling. Sometimes I see more networks than I am used to seeing.
Am I suggesting that you reinstall to eliminate the types of problems mentioned above? Definitely not especially if your problem is pretty minor. However, if your problem is significant, then think about it. Perhaps a greater than expected number of partially bad factory installs accounts for some of our problems.
I finished my reinstall only about 24 hours ago. I'll continue to monitor and will post back if I begin to see the wide signal strength fluctuations again.

Nope, thanks. I certainly advocate all trying any possible fixes prior to taking the drastic step of reinstalling. Hope the update works for all. I must of installed it yesterday with a number of other updates. Thus, it wasn't what "fixed" my system. But, it looks like it didn't hurt it either. Both are good to know:) Gosh, and looking at some of the recent posts in this category, I am glad that none of the recent updates hosed anything on my machine. Then, I'd me reinstalling again and being more selective about the updates.
I have to admit I have been throwing caution to the wind on doing all the updates. I think I'd better go back to my old style of seeing if there are update rumblings before I install them.

[How-To] Possible Fixes For Disortions + Missing Icons

Hi There
I just finished watching the webcast, and decided to download the new iTunes and after installing it...I experienced what most of you had experienced as well. Disortions on ALL music playback (with an external Creative Sound Card AND with the built in sound card and notebook speakers).
Here are some methods to fix these issues manually:
1) Icon Problems
Go to your My Computer >> Local "C" Drive >> Program Files >> iTunes >> right click on the iTunes.exe and click create shortcut >> the new shortcut has the new icon image on it >> rename it to just iTunes (optional) >> drag it to your desktop and you're fine
2) Sound Disortions
Open Up QuickTime >> Edit >> Preferences >> QuickTime Preferences >> Audio >> Sound Out:
Rate: 441.kHz
Size: 16 Bit
Click Apply (Don't bother trying to play a song in iTunes yet, it will sound the same) Once applied, click Okay, then quit QuickTime.
Once you have exitted QuickTime, Exit iTunes as well and ensure that both have been exitted properly. Close all active programs / including FireFox and then open up iTunes and try playing a song.
I am not an expert at this, I just happened to read othere members posts and followed the fixes and it worked for me.
The features including Gapless Playback all work for me and it is running smoothly for me now.
Have a nice day!

Hi,
I would suggest we try the registry key mentioned in this
article (Method 4) to configure Outlook to allow the connection to the mismatched domain name, and see if it works:
HKEY_CURRENT_USER\Software\Microsoft\Office\<var>xx</var>.0\Outlook\AutoDiscover\RedirectServers
Let me know if this doesn't work.

Possible fix for unable to eject ipod, files are in use by another program

If you get the above message and are using itunes 7, this may be a possible fix. Open itunes and connect your ipod. When you get the main screen, uncheck the box "open itunes when this ipod is connected" and then click apply in the lower right of the screen. After your ipod has finished updating (top of itunes says update complete) you must eject the ipod using the safely remove hardware from your tray in the taskbar. Unplug you ipod, close itunes. Now, open itunes and connect your ipod. After it updates, you should safely remove the ipod. Good luck.
pc Windows XP Pro

Easy way. Reset the iPod, then disconnect when you see the Apple logo.
Another way. Hold ctr-alt-del to bring up the Windows Task Manager. Go to the Processes tab and look for iTunesHelper.exe and iPodService.exe. Select them and hit the End Process button. Close the Windows Task Manager Window and try ejecting the iPod via the safely remove hardware method.
  If you are still having problems you can try one more thing. Right click on the My Computer icon and select Manage from the list of actions. Go to the Services and Applications item and from there the services item. Double click on the services item to bring up the list of services currently installed on your computer. Look for the iPod Service and double click on it. From the new window select Stop. Now try again to eject using the safely remove hardware option.
  If all else fails shut down the computer and disconnect the iPod.
