[alsa-devel] SBx00 Azalia ALC663 Working but MIC goes away

Tue Jun 28 15:33:50 CEST 2011

I already sended this mail to this list ... many times .. but it gets
bounced or wait for moderation. I find this annoying.
I am attaching the files compressed now.

I tested the solution mentioned by Takashi.
I have installed alsa-driver-kmp-default and restarted, but i found
 the same behavior so, i didnt make more alsa-info files.
However, i dont know what is "the right repository",
i choosed "multimedia:audio:KMP/openSUSE_11.4"
and also tested "multimedia:audio:KMP/openSUSE_11.4_Update" which
provided the same file.

The file is installed in
linux-i1zx:/home/diego # modinfo snd-hda-intel | grep filename
filename:
/lib/modules/2.6.37.6-0.5-default/kernel/sound/pci/hda/snd-hda-intel.ko

 I have also tested model=m51va which also didnt helped.

 I dont think that the model, or model-autodetection is the solution for this.

 I mean, the problems gets solved after restarting alsa. So alsa does
 handles the MIC.

 I noted that in /etc/modprobe.d i have 2 sound.conf files.
 One is 50-sound.conf and the other is 50-sound.conf.YaST2save

 I dont know what is the second one for. If i use yast to edit the
 configuration, which i did, it edits the 50-sound.conf

 And also, all other files are numbered 50.
 What would happen if i change the sound to 51 to make the sound load
 after everything else?
 Could it break something ? like Yast ?

Hi people.

I am having this problem for a long time ago, and i couldn't find the
same on google, or a solution for it.
I also don't know the right way to write the question to google,
because almost all are about problems that i don't have.

OpenSUSE 11.4 installed about 2 Months ago.
ASUS laptop n51tp
Athlon X2
ATI Mobility™ Radeon® HD 4650
Audio System:
Built-in Azalia compliant audio chip, with 3D effect & full duplex
Built-in speaker and microphone
Support Audio Jack Detect for Vista Basic Logo
Support Audio CODEC criteria for Vista Premium Logo

AUDIO WORKS but with a problem listed below.

ABSTRACT:
- MIC never works after booting. It needs an alsa restart and gets
broke sometimes..

DETAILED:
If i start the laptop with no external headsets or speaker connected
in front panel. Audio goes through internal speakers.
When i connect an external speaker or headsets (like to talk with
skype), they don't work. And MIC doesn't works.
This is undesired behavior and the windows driver doesn't work that
way. Internal goes mute when i connect an external.
Causes trouble when speaking with skype, as everyone can heard.
I have to reset alsa with "rcalsasound restart" with headsets plugged in.

IF i start the laptop with the headsets plugged in. The internal
speakers will not work at all. Always in mute. But the external will
work. Also the MIC wont work.
I have to reset alsa with "rcalsasound restart" with headsets plugged in.

If i do some work with the laptop using different multimedia sources,
it may broke.
Most of the time i get called by skype and the MIC is surprise
surprise, not working. Then i have to close all programs, restart alsa
and open skype again to be able to talk.
Thats the main reason to post here.

TESTS RESULTS:
I have runned alsa-info.sh with a different set of tests. So i write
the cases for each one, and the filename of the attached.

----------------------------
Boot without anything connected to Front panel.
Open Banshee and play.
Internal speakers works.
Plug headsets.
They don't work.
===> alsa-info.txt.noheadsets
Open Skype & do test call.
MIC doesn't work.
"rcalsasound restart" while headsets are plugged
Internal AND headsets are working fine.
Open Skype & do test call.
MIC works. Second call works best.
===> alsa-info.txt.workingright

----------------------------
Boot with headsets plugged.
Open Banshee and play.
Headsets works.
Unplug headsets.
Internal Speakers doesn't work.
Open Skype & do test call.
MIC doesn't works.
===> alsa-info.txt.headsetsnomic
"rcalsasound restart" while headsets are plugged
Restart Skype & do test call.
First call, noise recorded.
Second call, MIC works.
Unplug headsets.
Internal Speakers works.
===> alsa-info.txt.workingright2

----------------------------
With the "working right" condition.
Do normal tasks.
Open emesene & Skype.
Open Opera. (always leaved opened)
Open some pages with Firefox (hotmail & other flashintensiv sites)
Went to take a shower & Came back
Internal speakers don't work anymore.
Headsets works
MIC doesn't works.
===> alsa-info.txt.onlyheadsetsnomic
rcalsasound restart
Internal speakers works.
Headsets works
Skype requires to be restarted, banshee doesn't.
First call, noise recorded.
Second call, MIC works.
===>  alsa-info.txt.workingright3

In the gnome's Audio-preferences dialog, the input tab, the level-bars :
- show as ghosts when it doesn't work.
- shows green changing, when it does works.
- shows as ghosts if no program is using the mic and changes to green
if i start the recorder.
Restarting alsa requires closing Opera, Firefox, Skype, Emesene,
Banshee, etc. to work or some of them will broke the MIC again. It
also requires root privileges.

A broken headset also causes this behavior when i plug it, and then
MIC stops working until a reset.
By a broken headset i mean a very low quality crappy MIC Noganet,
which worked fine about 1 week, and then it started to only function
by placing the cable on special positions and not moving it. Don't buy
Noganet!

MY GUESS about the problems:
as almost electronic engineer.

The MIC may seem an initialization problem, as it never happened on
windows, but i don't have it anymore installed, since long now.

The driver requires to detect check for high impedance at the front
panel and mute the internal ones, and/or provide a way to mute them
separately.
I wonder why i cant see my headsets as a separate entry of the mixers.

A short-circuit problem may be happening in my front panel, and under
some circumstances, like moving the cables, it causes some chipset
failure over the MIC controller. The driver is not handling this error
and it stays crashed until a reset.

However, it doesn't explains why seeing a video in flashplayer in
opera may cause this too.

I will appreciate any help, and thanks to everyone reading this not-short post.
Cheers.
Diego

Only "Master" and "Capture" are shown on alsa-mixer. Both full. But
the problem here is not the volume.
