Alsa and probing snd-hda-intel

aikempshall · 10-22-2006, 05:51 AM

I boot from an external USB drive originally on a IBM T30 from this weekend is on an Lenovo T60. Two remaining issues to sort out is sound and the internal lan card.

On the question of sound I've

recompilled the kernel
recompiled ALSA

and finally
reinstalled alsa-driver-1.0.9b_2.4.31-i486-1.tgz

The response I get to an modprobe snd-hda-intel is -

Quote:

/home/alex# modprobe snd-hda-intel

I've never really understood what

means!

Can anyone point me in the right direction?

i think it's because you recompiled your kernel. The alsa-driver packages was meant to be used with the default kernel provided by Pat. If you want to recompile your kernel, you need to recompile alsa-driver (from source) and you can skip alsa-driver from Pat

Or if you are using kernel 2.6.x, just include all ALSA section as kernel modules and that's it. YOu don't need to install alsa-driver anymore as it's already included in the kernel.

Thanks for the reply. Problem gone away!

Had another problem, that I'd identified before the one above, in that my initrd had to be changed to load the ehci-hcd module instead of the uhci module as moved from solely USB 1.1 to USB 2.0. In doing that it cured the problem above - hmmmm!

After a bit of work, with alsaconf, alasmixer and alsactl, got sound to work albeit with kmix muted which I will look into later if the mood takes me.

Will also take a look at ELF - never had understood it!

Thanks
