Thanks for this background information :-) Am I correct in asuming that this more or less is still true, and I'd rather continue to build sound support as modules? > ... > I suggest you use alsactl init before and after and compare the output > between > a working and non-working state, to try to isolate the problem. Erm ... good suggestion: $ alsactl init alsa-lib /var/tmp/portage/media-libs/alsa-lib-1.2.3.2-r1/work/alsa-lib-1.2.3.2/src/ucm/main.c:983:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -2 Found hardware: "HDA-Intel" "Realtek ALC269VC" "HDA:10ec0269,15586508,00100202 HDA:80862809,80860101,00100000" "0x1558" "0x6508" Hardware is initialized using a generic method /usr/share/alsa/init/default:102: value write error: Input/output error /usr/share/alsa/init/default:263: value write error: Input/output error /usr/share/alsa/init/default:263: value write error: Input/output error $ echo $? 99 $ Running "sudo alsactl init" produces exactly the same result. So what's broken here? Or what to try next? Sincerely, Rainer
