No sound with Realtek ALC850
 

Problem: Trying to play an mp3 with mpg321 gives the output "no libao driver". I'm using Asus's K8N4-e deluxe motherboard which uses Realtek's ALC850 onboard chip.

I've posted about this before, but the post was trying to solve too many different issues, and with the complication of not having any way for me to get screen output posted to this thread (see caveats). Now, though, I have a digital camera at my disposal.

Experience level: I've been a linux user for several years now, but am still mostly a semi-competent curious newbie who likes to rtfm. I'm comfortable compiling the kernel.

Caveats: My linux box is a wreck, and has been since January (the withdrawal symptoms still haven't dissipated). I'm forced to use this winbox for anything more productive than looking at error messages. This means any screen output you want to see has to be captured by camera and uploaded via my dial-up connection. I've got the time if you've got the time.

try installing libao packages from l directory on Slackware repository. Here are the descriptions

They're already installed. I did the full three or four gigabyte installation when I slapped slack on my hard drive.

could you list your libxxx packages here?

Oh blast. I'm very sorry to be all flakey, but I found out (on a different thread) that I did terrible things to my Slackware installation, and so I'm properly re-installing Slackware 10.2. Unfortunately, I made it all the way through installing disk one before I found out there is a second disk I need. Because of my dial-up, I have to wait till saturday when I have arranged to have access to high speed internet to download the second disk and finish installing.

I will be back with my problem, though, I'm sure.

Just so I know, you want a listing of my /usr/lib/ ?

no, your lib-related packages
just run

I'm now using a custom kernel, version 2.6.16.14.

The pics are approximately 35k each. In order they are: lspci, the two screenfuls of ls /var/log/packages | grep lib.

Alas, I'll have to make do with only disc one of Slackware 10.2. My arrangement fell through. All the really important stuff was on disc one though, right? Leastwise I remember reading that somewhere.

Ah, one more rather important screen output:

Am I doomed?

If you want to read manpages, I suggest downloading some of the packages form the 't' directory. I think this is on disk2 but I could be wrong.

As for your problem; the message "alsa device list, no sound cards found" worries me. Looks like you need to do a kernel compile and add in "sound support" as a module. Then add in modular support for alsa and the appropriate soundcard. OSS support not necessary if you have it selected in alsa menu (backwards compatible). Once finished, run 'alsaconf' and 'alsamixer' to unmute output channels.

note: it is necessary for all of this to be compiled as modules for this to wrok.

Still does not work? Please post the output of 'lsmod'

Okay. I'll try compiling alsa and soundcards as modules instead of directly into the kernel.
