Public bug reported:
Binary package hint: linux-source-2.6.20
I have a Compaq Presario V6030us, which contains an nVidia MCP51 audio
chip. I am running Kubuntu.
Under Edgy, I needed to recompile the kernel and then install alsa
version 13, since the version 14rc1 which came with Edgy did not work.
Whenever there was a minor update to the Linux headers I simply
recompiled the kernel and reinstalled alsa version 13. If I did not do
this, it was impossible to modprobe snd-hda-intel, and aplay reported no
sound card present (even though lspci recognised it) but if I did, it
was possible, and the sound worked.
Since taking the upgrade to Feisty today, I have not been able to get
any sound at all. I have removed and reinstalled alsa using Adept, and
also by doing the manual install of the modules (compile, make, make
install) of alsa versions 12, 13, 14, 14rc1, 14rc4 - all to no avail.
All of them result in no sound card being detected by commands like
aplay -l. Reboots, recompiling headers galore. I cannot modprobe the
sound card driver, and instead get errors like:
FATAL: Error inserting snd_hda_intel
(/lib/modules/2.6.20-16-generic/kernel/sound/pci/hda/snd-hda-intel.ko):
Unknown symbol in module, or unknown parameter (see dmesg)
I am, of course, incredibly frustrated that something which worked
before no longer works following a Ubuntu upgrade. I can't think of
what else to try - this must surely be a bug and isn't just my fault.
