Centos 6.2 sound not working on generic system

[magoo]

Hello,

I cannot seem to get sound working.
I have read other posts regarding sound issue, and have so far not come up with a solution.
I have loaded kmod-alsa.x86_64
lipci shows:
lspci | grep -i aud
00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller
08:00.0 Multimedia audio controller: C-Media Electronics Inc CM8738 (rev 10)
I have tried un-muting various devices in alsamixer.
System is dual-boot, and speakers work fine under Windows 7.

I have a generic system:
Motherboard: EVGA X58 SLI 3 / USB 3.0
Processor = Intel i7 950 3.0 GHz Quad Core (8 MBytes cache)
Memory 6 GBytes DDR3 triple channel
Sound Card = Turtle Beach Montego DDL, suports 2, 4, 5.1 and 7.1 multi-channel speaker configurations, Dolby Digital Live

Thank you for your help.

Welcome to the CentOS fora. Congratulations on being one of the select few to do the recommended reading before posting.

I can't spot any obvious problems, except that you have multiple 3rd party repos enabled and are not using the [url=http://wiki.centos.org/PackageManagement/Yum/Priorities]yum-plugin-priorities[/url] plugin, large amounts of trailing whitespace (manually deleted), and the strange lack of network information in the script output. Did you remove it?

[magoo]

Hello,

Yes, network info was manually removed from getinfo.sh output.
Centos and Windows seem to be fighting over the driver. Windows works with my C-Media PCI Audio Device (or at least it did until I started trying to enable the sound on CentOS).
On Windows, the driver details point to cmudax3.dll and cmudax3.sys. Not sure if there is a driver that will play nice with both OS's.
Driver version is 7.12.8.1740 from C-Media Electronics.

Thanks.

[pschaff]

There should be no interaction between CentOS and Windows drivers, except possibly for a warm-restart. Have seen cases where hardware "remembers" things through a reboot if not power cycled.

[azca]

Hi all. I also have a C-Media CM8738 sound card that did not work OOB on my test 32 bit CentOS-6.2 install. The installation method on this computer was a minimal install from the DVD.

The solution for me was to simply install kmod-alsa from elrepo.org, and then alsa-utils from the regular CentOS repositories for testing purposes.

FWIW, I am using runlevel 3 console mode for this. No GUI.

After installing kmod-alsa, and alsa-utils, and then rebooting, I now have this:

[username@celeron ~]$
[/code]
I ran alsamixer, and the card was properly detected in the upper left corner, and nothing was muted.

Next I tested some sound files provided by alsa-utils.

[code]
[username@celeron ~]$ cd /usr/share/sounds/alsa/

[username@celeron alsa]$ ls -al
total 1220
(...)
-rw-r--r-- 1 root root 137134 Nov 10 2010 Front_Center.wav

[username@celeron alsa]$ aplay Front_Center.wav
Playing WAVE 'Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
[username@celeron alsa]$
[/code]
I now have sound while in runlevel 3 console mode. I do not have sound while in GNOME yet, but that's most likely because this is a minimal install, and so I'm probably missing some packages. Just haven't has time to look into that yet.

Anyway, hope this can help someone.
