About the sound system...

Hello! I have a macbook pro 2009. A few days ago I accidentally spillover a very little amount of coffe on it. For this my keyboard went in to collapse, the "shift" it is glued and a lot of keys dead. I buy a external keyboard for the time being because repair a mac is expensive. I need save money first.
My real problem is the sound system, initially later of the coffe episode, all less the keyboard are all right. yesterday I falling sleep listen music with my mac and external speakers. In the night the machine turn off and when I wake up the sound never worked again. The mac dont recognizes or external speakers or integrated sound. My doubt is, there anything I can do for the time being for solve the sound problem. Until I have the money for to take it for service?

Trying to understand the sound system

Here's my problem. My mic didn't work (neither the front mic nor the line-in in the rear), so after some research and trial and error I found that if I do
modprobe soundcore
my mic works on both the jacks
But here's where my confusion lies. This is the output of lsmod |grep snd before probing explicitly for soundcore
[inxs ~ ]$ lsmod |grep snd
snd_hda_codec_analog 78696 1
snd_hda_intel 22122 1
snd_hda_codec 77927 2 snd_hda_codec_analog,snd_hda_intel
snd_hwdep 6325 1 snd_hda_codec
snd_pcm_oss 38818 0
snd_pcm 73856 3 snd_hda_intel,snd_hda_codec,snd_pcm_oss
snd_timer 19416 1 snd_pcm
snd_page_alloc 7121 2 snd_hda_intel,snd_pcm
snd_mixer_oss 15275 2 snd_pcm_oss
snd 57786 8 snd_hda_codec_analog,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm_oss,snd_pcm,snd_timer,snd_mixer_oss
soundcore 6146 2 snd
[inxs ~ ]$
So as you can see, soundcore's already loaded, so why do I have to explicitly load it again to get the mic to work?
Once I add soundcore to my MODULES array and reboot, the lsmod output is also the same as above.
So my question is -- what does the explicit loading of soundcore do, that is not done by auto-loading of that module?

Oh... since your topic is Trying to understand the sound system, that puts you (and me) inside the whole world's population... chuckle. But I thought I'd pass along a document written by probably "The" main ALSA developer that I totally stumbled across just 3 days ago.
Go here:
http://kernel.org/pub/linux/kernel/people/tiwai/docs/
and download the flavor of your choice of the "HD-Audio" document, or simply view it online. It documents the deepest dive into the current ALSA snd_hda_* layers and issues that I've found to date (but still leaves me wanting).
Why that document isn't plastered across the interwebs is beyond me. I only get 11 hits when I search for it... such are the secrets of the ALSA world I guess.

In CIF customer exit there is no information about the logical system

Dear All,
we have a SAP R3 system (ver 4.7) connected to 2 SAP APO systems.
we need to differentiate the UE code in R3 by APO TARGET SYSTEM.
In the CIF userexit used:
EXIT_SAPLCLOC_001
EXIT_SAPLCSRS_003
EXIT_SAPLPGS1_001
EXIT_SAPLCSTK_001
EXIT_SAPLMEAP_001
there is no information about the logical system (source, destination
etc.) The control parameters are not provided to the user exit.
I found a note 1060634 where the parameter have been added to
EXIT_SAPLCSLS_002 , but not to all other exits.... do you have any clue on how we can proceed?
Thank you !!
Best Regards , Barbara

Found the answer, to bad i cannot give points to myself :-P
In the ABAP i use the E_T_RANGE output structure.
That structure has several fields (sign, opt, low, high).
In my ABAP i stored the same value in the low and high field.
This should work fine for normal (flat) characteristic values.
However, because i use a hierachy i should enter the 0HIER_NODE value in the high field.
For details see: SAP NOTE: 912473

Gripe about the points system...

To whom it may concern,
I have a gripe about the points system used on the forums.Let me start by saying I like the general premise the points system offers but... I have noticed that I certain cases I will receive SEVERAL equally good, helpful, and valid replies to a post. My gripe is that when it comes time to award points I see a problem. In the above scenario AT LEAST one posts MUST get solved points while the others only get helpful points. I don't like this as oft times I believe EVERY answer deserves equal points. I would like to see the system at least allow for all posters to receive helpful points. I feel that in some cases this would keep things fair. Thank you.

I have an Apple TV, a sound system and a video projector. The videoprojector and the sound system are separated by 5 meters and I cannot have a wire. What would be the wireless possibilities?

Should I put the Apple TV next to the video proj and send the sound wirelessly to the sound system but how to do this from an optical output? Or I can put it next to the sound system and send wirelessly the HD video signal but I have not found a solution unde 100+$ and people seem to be complaining. Any ideas? Thanks in advance

It is pretty short so here is the entire text:
Symptoms
A purplish or other colored flare, haze, or spot is imaged from out-of-scene bright light sources during still image or video capture.
Resolution
Most small cameras, including those in every generation of iPhone, may exhibit some form of flare at the edge of the frame when capturing an image with out-of-scene light sources. This can happen when a light source is positioned at an angle (usually just outside the field of view) so that it causes a reflection off the surfaces inside the camera module and onto the camera sensor. Moving the camera slightly to change the position at which the bright light is entering the lens, or shielding the lens with your hand, should minimize or eliminate the effect.
Which is exactly what eelw wrote.

Doubt about the distribution system

I have a doubt about the distribution system.

Thanks!

I don't understand this reply at all. Many of us have been using acrobat.com in exactly this fashion, and I've posted about it many times; including a full review:

Did Adobe not see this coming? How would you limit the download amount without gutting the functionality? Would this apply to paid acrobat.com accounts as well?
I'm about to upgrade my acrobat.com account this week to host more than 1 folio. You need to clarify what you mean by 'modify the user agreement' ASAP.

Question About the Sound Blaster Ca

I haven't yet read all the info on ever one of your cards, but was hoping one of you Creative Labs guys could answer my question for me. I looking for a card either now or maybe one you guys could think about to do more than one sound at a time. Meaning... Say I'm playing a PC game and have the game playing on my computer speakers.. or in my case. On my Home Stearo system. And I have a program, which in my case is Ventrilo. (Which is a Computer Specking program used to talk with other players online that are in our server) Now Looking for a card to play the game on the stearo speckers and the sound from vent (people talking) on my headphones. So You are hearing the game on the speckers in great 6.7 7., 5. sound.. and the talking is all coming though on the headphones.. so you can hear the people easyer when they are talking. Also making it more realistic. Sorry about my spelling also. Hopfully you guys will be able to see where I'm getting at. Maybe the card could do up to three different sounds on three different soucres. So is this card real? Something that could come out? Or just somehing that couldn't happen on a PC card. Thanks for reading.

If you can specify which soundcard the program uses when you talk to other people, I have a setup that might work for you. Instead of trying to combine all of that into the soundcard, use the soundcard just for the game. Then use a bluetooth headset and a bluetooth network adaptor for the voice chat. The bluetooth antenna I have shows up as a second soundcard called bluetooth audio. If you can't specify which soundcard the program uses though then this most likely won't work.

Technical reference about the apple system preferences files

Hi Community,
is there a technical reference or at least a short description about apples system preferences files in Snow Leopard available? I don't mean the structure of references files as a whole but the meaning and functionality of a specific plist.
Thx & Bye Tom

Some apps may automatically add themselves to this list, controlled by their
own preferences. But that is indeed the preference that controls that list.
I'm confused because after this experience I found a lot of tutorials, documentations and forum discussions which describes the loginwindow.plist as the responsible plist for the login items. My suspicion was that the loginitems.plist rebuild process take notice about the content of loginwindow.plist, which is in the root of the matter the same as in loginitems.plist.
But I couldn't answer this question competent and that's the reason why I'm searching for detailed informations about this "forgotten" loginitems.plist. Forgotten? Try to search for it. Its unbeleavable, 99% of the hits you get belongs to the loginwindow.plist and the description sounds very similar to the functionality of loginitems.plist. But maybe you're right and the applications try to put themselves back into the startup item list. But this doesn't answer the relation between this two plists.

HP updated my BIOS and now the sound system doesn't work on Dv76012Tx.

HP Care / Support Assistant requested to update my BIOS, which I did. Computer restarted a couple of times then I found my sound system doesn't work. My computer is Dv7-6012Tx and it is just a week old. I now get no sound, and it had been working beautifully.
Please reset my BIOS back to how it was.

Had the same problem as of about 30 minutes ago. New BIOS update, sound doesn't work. Drivers all read as up-to-date. What the hell?

Disappointment about the security system

Dear Apple,
Myself Gokulakrishnan, I am a new I Phone user, i am very very disappointment about your security system because of your siri application.
i have this problem i need a perfect explaination about this,
here i stated my problem,
I use passcode lock for the security purpose, but when i try to call my friend using siri before enter the passcode. the call is activated i am really shacked, how come the calling is going? if any one use my phone like this who will bare that charges?
i already check the options but i can find the way. please give the prapare solution or explanation.
i am witing for your reply.
thanks
krishnan

I'm not aware of any built in method to accomplish this. You'd have to come up with the custom way of doing it. You could put a web page in front of the main peoplebooks page that asks for login credentials and link that to PS somehow. Maybe use LDAP? In any case, it sounds messy and doesn't really seem like it's worth the investment. -Mike

About the Nonlinear System Solver

Hi, I am trying to solve a nonlinear system that is a little complicated to get the solution manually:
B*Sin(P)/(2*sin(B)*b)=0
B*Sin(W)/(2*sin(A)*b)=0
A+B+P+W-180=0
I tried to use the Nonlinear System Solver entering the formulas and
all I get is an error code -23001 (Error -23001 occurred at an
unidentified location Possible reason(s):
Analysis: Syntax error of parser. "
I don't know what I am doing wrong, I am doing it similarly to the
attached VI, with my own equations and controls. I even tried to change
the equations so I would delete the "sin" (sine), just to make a test
(about syntax and the solver not understanding that command?), and I
got the same error.
Help is much appreciated,
Thanks

Also remember that the argument to trigonometric functions must be in radians here.
Are you sure that A and Beta are not [0<A<π/2], [0<Beta<π/2].
How about the "180" in the last formula. Shouldn't it be π instead?
Is b 83 degrees or just a constant of 82?

Connect to HDTV, what do you do about the sound?

Hey there.
I am thinking of linking my new shiny MacBook to my HDTV via HDMI.
I used to link my iMac to my old 42" plasma TV by an RCA connection (it was an old Plasma TV) so I just linked the RCA to the headphone out and I had sound and picture going to the TV. Simple.
But the HDMI allows audio signal, but the apple connector doesn't do the sound. (or does it??)
How then, do you link the sound to your TV?

You can still use those same cables. I'm assuming you're using these cables...right?

A bug in the sound system?

Hello there
I found a funny thing in the iPod functionality of my iPhone 3GS with software 3.0.1.
I synced a movie, I converted myself with ffmpeg (ffmepg rulez!!!) to the iPhone. The converted movie played well in QuickTime nad VLC on my iMac, but if I play it on my iPhone, there is no sound. Strangely enough, not only the movie has no sound, but after playing that movie, no sounds are played in the iPod application anymore at all. No MP3s, no podcasts, no videocasts, nothing. Even the ringtone is totally silent. The tone for text messages, emails, calendar events, key-click, lock sounds and sound from other apps (like games) play well. But no iPod, and no ringtone.
To solve this problem, I had to restart the iPhone (hold power button until the red slider appears, and switch back on) with the headphones connected.
I don't know, if this happens with 3.0.
The behaviour is reproducible, just play the "buggy" video.
If anyone is interested for what reasons ever, I can post the ffmpeg params I used to convert the video.
Funny thing, I'd be glad if Apple could fix this.
And I for myself will start looking for more suitable encoding parameters for my videos.

Hi, I don't play videos on my iPhone, but i also thing there is something wrong with the sound... Some times it just disappear, when i receive phone call I see on the screen that someone is calling, but no sound. The same happened with the alarm clock. I was awake already and look to see what time is it, it had the message ALARM, but no sound at all...
After restarting it seems to be ok for few days. Is it possible to be from overheating ( I have a silicon case ) ? Or is it a normal bug in the phone itself?
I will appreciate any responses
Thank you

What's so hard about the file system?

I've heard that the file system is hard to understand/navigate recently. I heard Jobs mention it yesterday in the keynote.
I just don't get it. Since OS X they've made a home folder. That's pretty simple. Is this a case of catering to people
who are very new to computers?
I made a folder called Art. In it are all my works in folders with appropriate names. When I save a file from Illustrator
and put it in the art folder the next time I save it goes in that same folder unless I change the path. That's pretty
straight forward, no?
Thanks for any insights.

> Is this a case of catering to people who are very new to computers?
My guess is yes. Apple has been getting a lot of new Mac users via the iPhone, iPad, iPod, and iPod Touch devices which do not expose the file system to the user.
It is my guess that based on support calls, they figured if they minimize the need to understand and navigate the file system, they will have happier customers, where that is an over all average and not necessarily specific cases of experienced users.
One area where new users get confused is where should I put something? There are different existing folders, but they can create their own. Should they use an existing folder, or create their own. Documents sometimes becomes a dumping ground until it becomes difficult to find things. Should the user create a new home level folders or subfolders in Documents?
There are 3 Library folders (assuming you know where to look), what goes where. home folder -> Library is not used consistently by all applications which can confuse users that figure out how to find something for application X, only to have application Y store it differently.
Besides you cannot argue with the success of the iPhone, iPad, and iPod Touch, and Apple does look at its bottom line and everything there is telling them "Less is More".
