VIA 8237 AC97 Audio not working in FC4

I am am having some trouble with my sound card (onboard via 8237, or so I think). I know it works because the first time I installed fedora core 4 it played test sound in the installation.

Hi!

I am am having some trouble with my sound card (onboard via 8237, or so I think). I know it works because the first time I installed fedora core 4 it played test sound in the installation.

For some reason it stopped working when I reinstalled FC4 (messed around alot to get atheros wifi running for my kernel and thought I'd better undo any damage before I start working :) )

I installed all the audio packages from the cd's just to be sure but no change.

I have gone thought all the alsa mixer settings and made sure nothing is muted. I have also toggled the troublesome external amplifier setting a couple of times.

Here are some helpful hints:

Hi,
Excuse me, here is a frustrating experience. Some month ago, my PC remained mute, without any explanation. Then I remembered that the PC was manipulated (for casual reasons): indeed, the loud speakers were incorrectly connected back.
G.R.

[musicalDuck]

Nope, tried plugging headphones in any which way, no luck.

I have a 6.1 speaker setup plugged in now so I am sure to notice when there's sound on a channel :)

There is a an alternate driver tho, which apperntly outputs through the mike plug but I need recording capabilities.

Any thoughts?

[mpolo]

Another "quick fix" is to run alsamixer from a terminal. It often turns out that the main volume is muted by default.

It looks like you are missing the "install" line for your sound card in modprobe.conf. I have an Intel AC97 chip, and mine looks like

install snd-intel8x0 /sbin/modprobe --ignore-install snd_intel8x0 && /usr/sbin/alsactl restore >/dev/null 2>&1 ||:


I presume your line should be analogous.

[musicalDuck]

Think were on to something here, where in modprobe should that line go and should I remove this line ?

remove snd-via82xx { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-via82xx

Checked the alsamixer settings from the command line, everything looks ok. If someone has the same soundcard as me I would realy apreciate if they posted there mixer settings (especially the external amp and other misc. toggle options)

How does one restart a service properly in FC? I am wasting time rebooting for every test. (Also reminds me of the unmentionable OS grrr)

Thanks for all the help so far guys!

[mpolo]

I have the install command before the declaration of options for the sound system, right after the aliases at the begining of the file. The "remove" line is the command that will be used when the service is stopped, so you need that in there.

To restart a service, from the command line, you can use /etc/init.d/servicename restart; or from the GUI, go to System Settings>Server Settings>Services.

[musicalDuck]

mmm, nothing yet.

Does anyone also have this card?

[musicalDuck]

Mmm hows this for wierdness.

Updated my kernel. This did'nt fix the problem outright tho but if you like x-files stay tuned.

I was messing about and my terminal suddenly crashed. But this evilness was soon forgotten when I was greeted by a gnome sound when I opened a new one terminal!

I updated my alsa drivers as well and everything seems to be working now but I have some doubts as to how long it will remain working.

I am still using the conf files from this post tho if anyone else gets this problem.

Any comments in light of this new info?

[musicalDuck]

Oh dear sound went away again.

Any thoughts on what might be causing this?

I am stilling running as described above.
