Hi,
Trying to rephrase my question a little.
I have a motherboard with a built in soundcard that the docs simply lable as "AC97". I see a module ac97.o, and it doesn't complain when I load it, but there's no sound.
So here's my question: could someone shed some light on what exactly AC97 is?
I've read a few papers on the net. Am I right in thinking AC97 is an application interface, as opposed to a chipset standard (in other words the ac97 module is an API that still requires a chipset specific driver) or have I misunderstood something?
I think it is. ALSA have not released a stable version in a while, but I have been using the unstable series for a while with no problems. I have two cards right now using the unstable drivers (ALSA 0.9 series). I suggest trying them. Try lspci to see if it reports what kind of chip your motherboard has, here is some output from mine:
00:04.0 ISA bridge: VIA Technologies, Inc. VT82C686 [Apollo Super South] (rev 1b) 00:04.1 IDE interface: VIA Technologies, Inc. Bus Master IDE (rev 06) 00:04.2 USB Controller: VIA Technologies, Inc. UHCI USB (rev 0e) 00:04.3 USB Controller: VIA Technologies, Inc. UHCI USB (rev 0e) 00:04.4 SMBus: VIA Technologies, Inc. VT82C686 [Apollo Super ACPI] (rev 20) 00:04.5 Multimedia audio controller: VIA Technologies, Inc. AC97 Audio Controller (rev 21)
So the chip is actually the VT82C686. As you can see this chip does a lot. Good luck!
Thanks to all who replied. You confirmed my suspicions that it's not enough for a chip to be AC'97, the specific chipset has to supported as well. That was what I though, especially considering that lspci called it an "unknown device" and that yast2(alsaconf) didn't recognize it.
What kind of motherboard is it?
