Greetings,
I would really appreciate any help. I don't come close to understanding how all the different parts of the linux sound system fit together and working on my computer without music is painful!
Fresh install as in the title. The sound is via an onboard ALC1200 chip according to the manual. I believe this is very similar to the ALC888 but I'm not sure if I can force that driver to run. I'm using the default 2.6.26.5-45.fc9.x86_64 kernel.
using lspci it looks like the kernel can see the sound card, though as an unknown device.
00:1b.0 Audio device: Intel Corporation ICH10 HD Audio Controller
Subsystem: ASUSTeK Computer Inc. Unknown device 82fe
Flags: bus master, fast devsel, latency 0, IRQ 22
Memory at fe9f8000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: HDA Intel
Kernel modules: snd-hda-intel
In var/log messages it looks like it finds the sound card here, but can't do much with it:
Oct 13 07:57:02 aelfheim kernel: ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 22 (level, low) -> IRQ 22
a bit later:
Oct 13 07:57:02 aelfheim kernel: hda_intel: azx_get_response timeout, switching to polling mode: last cmd=0x100f0000
Oct 13 07:57:02 aelfheim kernel: hda_intel: azx_get_response timeout, switching to single_cmd mode: last cmd=0x100f0000
finished off with pulseaudio complaining about its permissions and a continuing stream of:
Oct 13 13:36:23 aelfheim pulseaudio[2724]: alsa-util.c: Unable to determine current swparams: Operation not permitted
Oct 13 13:36:23 aelfheim pulseaudio[2724]: module-alsa-sink.c: Got POLLERR from ALSA
Oct 13 13:36:23 aelfheim pulseaudio[2724]: module-alsa-sink.c: Could not recover from POLLERR|POLLNVAL|POLLHUP with snd_pcm_prepare(): Input/output error
The various desktop tools basically tell me there's not actually a card there. With pulseaudio telling me I have no sinks, sources or streams and nothing available. The expected sound modules all appear to be loaded and happy.
Is this indicating the audio is simply not supported by linux (though some people on the ubuntu forum claim to have it working) or is it a configuration error?
