[gentoo-user] Intel HDA soundcard, microphones and skype

[Matthew R. Lee]

I'm trying to get skype set up on my new laptop and I've run into a problem
the sound card (Intel HDA) is setup and working (with mplayer and amarok)  
I've installed skype and the interface is working.  There nothing wrong with 
the headset (it works on my old laptop). At first I kept getting "problem 
with sound device" error but I've solved that but the microphone doesn't 
appear to be working.  When I make a test call I can hear the skype lady but 
I can't here my message when they try to play it back
I've checked the alsa mixer and the microphone is set to capture and the 
volume up.  I don't know what I'm missing.  Sofar I havn't turned up anything 
in the wiki or forums.
Has anybody got skype woking with this soundcard.  Perhaps you could post 
your .asoundrc for me to have a look

Thanks
Matt

Skype is easy to set up, IF you have alsa working right...

Using alsamixer, turn the mic vol right up, can you hear your own voice 
in the headset? Make sure you have set the correct mic device, 
select "Mic Boost" if it's there. Last resort is to deselect other 
channels one by one and see if one of them activates the mic. I once 
had a chipset where the mic wouldn't work if a certain IEC958 feature 
was on. Until you hear your own voice in the speaker it will never work

Then in skype make sure you select the alsa/oss option as appropriate, 
it's somewhere in the Options. Skype uses alsa, make sure you do have 
full support in the kernel

I'm getting nothing from the microphone.
In alsamixer I only have four bars: Master PCM Line Mic
With all at 90-100%  The mic doesn't work with line or mic set to capture
Is there a way to fix that?

Sounds like there are only three options:

1. Mic is broken - safe to say it's not that
2. Kernel module is buggy - possible
3. Wrong kernel module or kernel compiled with wrong settings

I'd check #3. What's the relevant output from lspci, what module is in 
use and if relevant what kernel options are enabled for that module?

I have <*> Sound card support in the kernel (2.6.17-r8)
and then I installed alsa-driver package  I configured it following the 
alsa-guide in the gentoo docs
the sound card is Intel High Definition Audio, lspci:
00:1b.0 Audio Device: Intel corporation 82801G (ICH 7 Family) High Definition 
Audio Contoller (rev 01)
driver =snd-hda-intel

Unfortunately Intel's HDA isn't really a sound card, but a standard
way of talking to sound cards.  The actual chips are made by various
manufacturers, and it really is a bit of a mess.

1. You should not have a .asoundrc.  Current alsa versions (since
1.0.9) will automatically use dmix/dsnoop as necessary.  In almost
every case, it is wrong to have a .asoundrc.

2. Which version of alsa-drivers are you using?  1.0.13 would be my
recommendation, although you may have some issues with MSI
interrupts...

3. Can you post the contents of /proc/asound/card0/codec#0 and also
the output of "amixer"?

Hmm, your laptop has a built-in microphone?  Are you able to record
sound with that?

Also, have you tried recording sound with another app, like arecord or
krec?  Something that knows how to use the alsa API proper.

The laptop doesn't have a microphone, or if it does is well hidden
Tried using arecord and got the following error
matt# arecord -d 10 cd -t wav -D copy test.wav
ALSA lib pcm.c:2143:(snd_pcm_open_noupdate) Unknown PCM copy
arecord: main:550: audio open error: No such file or directory

It doesn't know what device "copy" is.  Try something like:

arecord -d 10 -f cd -t wav -D plug:dsnoop test.wav

At this point you may want to try the patch that you found on the
forums.  Unfortunately it doesn't apply cleanly against 1.0.13, and
the original patch author didn't release it under any defined
licensing terms, so it isn't legal for me to update it for 1.0.13 and
publish it.  So you will either have to downgrade to 1.0.11 and use
his patch as-is, or pester him for an update to .13, or even better
re-publish his patch under the GPL like the rest of alsa.

If you want to use the patch as-is, copy and save it to a file, such
as conexant.patch.  Then download alsa-driver-1.0.11.tar.bz2 from [1],
and put it in the same directory as the patch.  Then run (as root):

> tar -xjf alsa-driver-1.0.11.tar.bz2
> cd alsa-driver-1.0.11
> patch -p1 --ignore-whitespace < ../conexant.patch

This should work, but if you have problems (like crashes, devices not
being found, etc), you might need to downgrade alsa-lib, alsa-plugins,
alsa-firmware, alsa-headers, alsa-tools, and alsa-utils to version
1.0.11 as well with /etc/portage/package.mask.

Thanks for the help & info.  I'm in the UK at the moment and it's getting

I have the same problems (with a dv8000 laptop) I applied the patch to 
alsa-1.0.13 (after a few modifications) and the quality of the sound 
improved significantly. I also get more switches in alsamixer. However, 
the microphone still doesn't work. I have a column saying ExtMic in 
alsamixer, but it says only 'L CAPTUR R' in red, and has no volume 
control. Is there a way to make the microphone work as well?

Thanks,
Moshe

Just found a patch on the gentoo forums for this problem, but for the 
alsa-driver-1.0.11  I'm using 1.0.13
http://forums.gentoo.org/viewtopic-t-502890-highlight-microphone.html

Problem is I've never patched anything in my life.  How do I use this?
