Re: [gentoo-user] ALSA - Still No Sound

[Bill Kenworthy <billk@iinet.net.au>]

what does "lsmod" say?

This is on a jetway MB with an onboard nvidia chipset so not quite the
same as yours (only sound and the nvidia module are modularised) - in
particular make sure that you are building the "Intel HD Audio" codecs -
it isnt immediately obvious that its required.
