so i recently got my hands on an adamo 13″ black and decided to put gentoo on it. pretty straight forward.
after everything was installed i wanted to play some music through the headphones, and no sound came out..
so after a little googling this is what resulted :
cat /proc/asound/card0/codec#0 | egrep Codec
which gave me :
Codec: IDT 92HD73C1X5
weird…. i would have figured that an intel hd would be straight forward.
so after getting the codec i referenced kernel.org’s HD audio documentation and did a grep for “92HD73″ which lead me to this section:
STAC92HD73* =========== ref Reference board no-jd BIOS setup but without jack-detection intel Intel DG45* mobos dell-m6-amic Dell desktops/laptops with analog mics dell-m6-dmic Dell desktops/laptops with digital mics dell-m6 Dell desktops/laptops with both type of mics dell-eq Dell desktops/laptops alienware Alienware M17x auto BIOS setup (default)
so i added:
options snd-hda-intel model=dell-m6 to the end of /etc/modprobe.d/alsa.conf.
rebooted…and confirmed working….
kernel config for 3.3.4
