[gentoo-user] alsa and Intel HD audio

[Matthew R. Lee]

I'm struggling with getting my soundcard setup
from lspci
00:1b.0 Audio Device: Intel Corporation 82801G (ICH 7 Family) High Definition 
Audio Contoller (rev 03)

chip=Generic 14f1 ID 5047

I've compiled alsa support into the kernel:
Device Drivers --->
	Sound --->
		<*> Sound card support
		Advanced Linux Sound Architecture --->
			<*>alsa
			<*>sequencer support
			<*>oss mixer api
			PCI devices --->
				<*> Intel HD Audio

I've followed the Gentoo Linux ALSA Guide and the HARDWARE Intel 945G on 
gentoo wiki.  I've also checked the gentoo-forums and googled about
When I boot the kernel I get no error messages

cat /proc/asound/cards
cat /proc/asound/version
cat /proc/asound/oss/sndstat
all give the expected responses

dmesg doesn't report any problems

when I run alsa mixer I get on bar only  - master
that's it KDE says it can't detect the sound card
Sofar I havn't installed any other software that uses sound, but I intend to 
install amarok, kmplayer, realplayer etc

any help would be appreciated

I also have this soundcard. What kernel version are you using? I found that 
with 2.6.16 I only had one bar in alsamixer, just like you. However with 
2.6.17 I got two bars and the sound worked, but quietly. Some googling told 
me that the volume was fixed in alsa version 1.0.13, which is newer than the 
version in the kernel. So I removed alsa from the kernel and emerged the 
unstable version of alsa-driver, which is version 1.0.13. The sound is now 
louder, but still not as much as I would like. I get the impression that the 
driver for this card is a work in progress, so hopefully it will get better. 
Also this version of alsa identifies the chip in the card as being a 
Conexant, rather than just ID 5047, which has to be a sign of progress :-)

See http://www.gentoo.org/doc/en/alsa-guide.xml for information on installing 
alsa using alsa-driver rather than the kernel.

Did as you suggested and removed alsa from the kernel and compiled alsa-driver 
but It didn't work.  The only thing that changed was the name of the chip it 
detected, same as yours.  I still only have Master with alsamixer and no 
sound not even quitely  I'm using kernel 2.6.17-r8 and the 1.0.13 versions of 
alsa

This might be part of the problem:
When I try to play an mp3 with madplay I get the following error
audio: /dev/dsp: no such file or directory
Am I missing something from the kernel?

I'm not sure what would cause that, udev should be creating the device. On my 
system /dev/dsp is a link to /dev/sound/dsp. Does that exist?

I assume that your user is in group audio, so that you have access rights 
to /dev/dsp?

Fixed the problem.  I found the following solution on the gentoo forums.  It 
worked for me.  I think the problem was with the lack of alsa-oss :-)
Thans for your help

Matt

1. Use the alsa-driver ebuild instead of the alsa drivers in the kernel. 
Unmerge alsa-lib, alsa-utils, alsa-oss and any other alsa stuff you have. 
 
 2. Before you emerge alsa-driver, configure your kernel as per the 
instructions on the alsa guide using the method for alsa-driver users i.e. 
JUST sound support and nothing else. Then remove your kernel modules 
directory /lib/modules/whatever-your-kernel-is, rebuild your kernel and 
install it (make clean, make && make modules install, copythe bzImage file 
to /boot or however you choose to e.g. link it for your boot loader). 
 
 3. Clean up /etc/modules.d/alsa. Well, just delete it, to be honest. 
 
 4. Reboot with your new clean kernel. You'll probably want OSS emulation, so 
before emerge'ing alsa-driver, check your USE flags contain both alsa and oss 
flags. The alsa-driver ebuild will pick up on this. Emerge alsa-driver. 
 
 You should pretty much be back on track with the alsa guide now, just emerge 
alsa-utils (should pull in alsa-lib), and alsa-oss as well. Then run alsaconf 
again. Run alsamixer afterwards. Add alsasound to the boot runlevel (not 
default). Reboot.
