Mandrake 10, no sound - how do I investigate?


I've onboard sound, AC97 - the motherboard is an Elitegroup L7VTA. Mandrake 10 appeared to recognise this correctly, but there's no sound being produced.

Mandrake Control Centre lists the following:
Quote:
Vendor: ‎VIA Technologies

Alternative drivers: ‎via82cxxx_audio

Bus: ‎PCI

Bus identification: ‎1106:3059:1019:a81

Location on the bus: ‎0:11:5

Description: ‎VT8233 [AC97 Audio Controller]

Module: ‎snd-via82xx

Media class: ‎MULTIMEDIA_AUDIO
...I've no idea if this indicates the problem or not. Where should I go from here?

I would start by checking my mixer, they are often muted by default.

Also, do an lsmod and make sure the modules are indeed loaded.

I'd already checked the mixer (I'm not that naive, honest )

lsmod includes the following:

Sorry, had to ask. I once spent half a day on my sound only to discover that I had not plugged the speakers back in.

You may want to try the alsa drivers....details here.....


http://www.alsa-project.org/alsa-doc...module=via82xx

I have the same chipset and this was the only way I could get it working.

About the Alsa drivers I know I need to run ./cofigure but are there any command line arguments I need to use that I am unaware of? Running Mandrake 10, it says it's running the alsa driver for the soundcard now but I can't find the alsa mixer or anything. Can find the kde mixer which does me no good at all. I was thinking updating to the most recent drivers would give me the Alsa mixer but I have no clue how to proceed from here reading through the install manual now. Like it says this -
You must have full configured source for the Linux kernel which you
want to use for the ALSA drivers. Note that ALSA drivers are part
of the kernel, so there is necessary to resolve all symbol dependencies
between the used kernel and ALSA driver code. Partly installed kernels
(for example from distributor makers) can be unuseable for this action.
2) You must turn on sound support (soundcore module).
I think I have sound support on I have sound now, just can't use my mic, does this mean I can't use these drivers since I'm running Mandrake? Any help or a start point would be great sorry so long winded but N00b=me.

People, I'm sue he's already using the Alsa drivers, Mandrake usually includes them. I would try the OSS driver, once I had your problem and that worked.

Mandrake also offered the OSS driver - but switching to it in Mandrake Control Centre didn't help. I've followed the help instructions offered there, which gives the following info, which I don't understand at all - if any of it offers any useful hints, I'd appreciate an explanation

Quote:
# /sbin/chkconfig --list sound
sound 0:off 1:off 2:on 3:on 4:on 5:on 6:off

# /sbin/chkconfig --list alsa
alsa 0:off 1:off 2:off 3:off 4:off 5:off 6:off
....and "# /sbin/fuser -v /dev/dsp" gives no resulting information.
