 Posted: Fri Oct 08, 2004 10:42 pm Post subject: ALSA, cmi9880, built-in sound on mobo, no device detected |
 |
|
Ok... I've looked all over the forums, and I can't seem to find a solution. I seeked Gentoo's ALSA guide, but that did no help, either.
I'm running an Intel P4 Prescott on an Asus P5AD2 Premium motherboard. The motherboard has built-in sound using the Azalia codec, I think. The driver that is used for that codec (?) is cmi9880, but it is only available for Windows. I have tried running the most recent driver for linux (which is pre-cmi9880), but to no avail.

Can someone shed a little light, please?

Nice mobo. I just now looked up its spec. 
This is a brand new chip. Support for it was only added in Alsa 1.0.6 so it's going to be flakey if you can even get it to work at all. Give it a couple months. It is going to take time before the driver is ready for general use.
You might try downloading and using alsa driver/lib 1.0.7rc1 from the alsa web site. They are the latest developement versions that are not available in portage, but don't get your hopes up too high, it may not make much of a difference.

Thanks for the quick response!
I was wondering about compatibility with new hardware when I purchased... after all, it is my first shot at Linux. So far, though, the sound is really the only thing I have problems with. Getting the gigabit ethernet working was a trip, but at least its working now. Everything else was fine.

| I fought this problem for a couple of months-I am doing a new install of Gentoo, kernel 2.6.7, SELinux, with an nforce2 motherboard. There is a script, snddevices, that needs to be run to create all of the device nodes for ALSA to work. I downloaded a copy from sourceforge of the script and ran it, then sound worked great, including under SELinux in enforcing mode. I am led to believe that this script exists in the alsa-drivers package, which is otherwise not needed for 2.6 kernels. |

First off, a big thanks goes out to valueduser and masseya for their replies (and for pointing me here)!
I've managed to get everything detected with alsa 1.0.8. The output from alsaconf and amixer don't show any errors. Still, I can't get sound from my speakers. I think I have to fiddle with all of the settings; mute some, unmute others. I'll try doing that, and post back as soon as I see the light of success. |

Has anybody found a fix yet?
I've heard that the azx driver (or is it intel-hda?) works with this chipset. Right now, I'm recompiling my kernel without alsa built-in so I can pull in the latest sources from portage and try my luck.
The kernel built-in ALSA wouldn't recognize azx or intel-hda.
EDIT: It must be azx; alsa-drivers won't build with ALSA_CARDS="intel-hda" in make.conf .

I got it working. 
First, I added alsa to my USE flags, and the following line to make.conf:
Then, I configured the kernel without ALSA built-in:
| Code: | cd /usr/src/linux
make menuconfig
# Go to "Device Drivers" -> "Sound" -> "Advanced Linux Sound Architecture"
# Disable "Advanced Linux Sound Architecture" (press "n")
make && make modules_install
# Copy arch/i386/boot/bzImage, System.map, and .config to /boot |
I emerged alsa-driver and alsa-utils
Then I ran alsaconf and selected the "azx" option. It added the following to /etc/modules.d/alsa :
| Code: | alias snd-card-0 snd-azx
alias snd-slot-0 snd-azx |
Then, added ALSA to the boot runlevel...
| Code: | | rc-update add alsasound boot |
Reboot...
Then, configure the channels how you like with amixer
| Code: | | amixer set Surround 85% unmute |
(etc)
Hope this helps somebody... unless I'm the last person to figure it out.
