 |
|
There's a Gentoo system installed on Asus K42f laptop. The sound card is Intel Corporation Ibex Peak High Definition Audio (as lscpi says). ALSA is compiled in the kernel (2.6.32-gentoo-r7) and there is sound output (and alsamixer controls the levels correctly). However, there are two problems. First, alsaconf does not find any sound card. Second, the microphone does not work (however, there are mic-related controls in alsamixer). Where might the problem be?
dmesg says the following about sound:

Checkout the Gentoo Linux ALSA Guide
Generally it's recommended to build the sound driver as a module, and then alsaconf can handle that for you automagically, works great for me always. |
