Hi, I' ve just installed gentoo and I' m very impressed with the performance, and everything works perfectly. But I can 't get the sound working.
This is lspci | grep -i audio:
Code:

00:1b.0 Audio device: Intel Corporation NM10/ICH7 Family High Definition Audio Controller (rev 01)

This is aplay -l:
Code:

aplay: device_list:268: no soundcards found...


Thanks for helping me !

We don't know if this is custom kernel or not. What audio system is wanted, ALSA, OSS4? Did the sound work using some liveCD? If yes, what drivers were loaded?

lspci -k | grep Audio
Code:

00:1b.0 Audio device: Intel Corporation NM10/ICH7 Family High Definition Audio Controller (rev 01)
   Subsystem: Lenovo NM10/ICH7 Family High Definition Audio Controller


Yes, it is a custom kernel; I think sound worked in the live cd

kernel config problem, no driver

too early or too old, I applied right option to wrong command:
here:
lspci -k | grep -i -A4 audio
00:1f.3 Audio device: Intel Corporation Sunrise Point-H HD Audio (rev 31)
Subsystem: ASRock Incorporation Sunrise Point-H HD Audio
Kernel driver in use: snd_hda_intel
Kernel modules: snd_hda_intel
You probably also need snd_hda_intel plus appropriate codec(s) in kernel, may need firmware, dmesg may have clues
