audio for P4C800 and RADEON 9500 - help

[zyx4321]

WARNING: newbie at work. Even if I'm a straight Win, I'm becoming bi-curious, and eventually bi-OS.

Tried knoppix on my new Asus P4C800 based system, and have two problem: audio not recognized and don't know what video card choose (I have a RADEON 9500).

Anyone can help?

TIA.

I have a similar (not the same) m/b. For sound:

1. Make sure the onboard sound is turned on in the BIOS. I think that is the default anyway.

2. On the initial 'KNOPPIX 3.2' boot screen, hit f2 and enter 'knoppix alsa' on the boot parameter line.

If you then see the sound chip detected in the boot sequence you are in good shape.

3. If still no sound, open a console window and run 'alsamixer'. Use the <- and -> keys to switch channels, up/down keys to change sliders, 'm' to unmute a channel (little M at top disappears). Make sure at least the 'surround' and 'pcm' channels are turned up and unmuted.

If still no good:

(a) play with alsamixer a bit more. Turn up more channels.
(b) look at output of /sbin/lsmod. Are sound modules loaded?
(c) run xmms on a sound file. Are the LED's moving?

Video? Sorry - can't help there. But what is the problem?

Agro,

first of all, thank you for your help.
I believe sound is enabled by bios (I use it in Win without big problems).
I tried to set all channels to max volume and unmute with alsamixer. No gain.
xmms works, shows vu-meter bars (leds) moving, but no sound heard.

My bootup strange lines, not using alsa (boot without any command):

My bootup strange lines (using your suggestion, F2 knoppix alsa):

...

Seems to me that my mainboard (P4C800 Deluxe) is not completely supported (APM?). Just a feeling...

This is a capture of /sbin/lsmod:

PS: Video problem is the line:
Video is ATI|unknown device 1002:4164, using XFree86(vesa) Server
I don't know if it is a real problem (KDE is functional) but just to understand that "unknown"...

TIA.

Apologies to anyone who read this in the last hour or so. I had been using my HD installation, which has a recompiled kernel and sound, but I just rebooted from the 3.2 CD again to check the facts.

The boot process/loaded modules are exactly as zyx4321 describes. But then I open alsamixer and see the PCM and Centre channels unmuted and turned up. I change this from Centre to Surround and <ESC> to quit alsamixer. Then I have sound e.g. I can mount my HD and play an mp3 file using mpg123. Quality seems OK, but volume is not real powerful. Need mixer channels turned up to 75% or so to get good volume in headphones.

M/B: Asus P4P800-VM
Sound chip: AD1980 (AC97)

Sorry zyx4321 - if that doesn't work I am out of ideas. Note there is a lengthy thread on AC97 sound elsewhere in this forum.

You can also Google on your sound chip type. Note AD=Analog Devices, which may get more hits.

Later:It looks like the AD1980/1985 devices have recently made it into the ALSA soundcard matrix http://www.alsa-project.org/alsa-doc/. Following the links there gives more information.
