A little bit of progress... I found some lines in /etc/modprobe.d/modprobe.conf.dist which should not be there. I commented those lines here: #alias char-major-116-* snd #alias sound-service-*-0 snd-mixer-oss #alias sound-service-*-1 snd-seq-oss #alias sound-service-*-3 snd-pcm-oss #alias sound-service-*-8 snd-seq-oss #alias sound-service-*-12 snd-pcm-oss # #install sound-slot-* /sbin/modprobe snd-card-${MODPROBE_MODULE##sound[_-]slot[_-]} # #install snd-pcm /sbin/modprobe --ignore-install snd-pcm && /sbin/modprobe snd-pcm-oss && /sbin/modprobe snd-seq-device && /sbin/modprobe snd-seq-oss # alias nfs4 nfs alias rpc_pipefs sunrpc alias rpc_svc_gss_pipefs sunrpc install eth1394 /bin/true #install snd-emu10k1 /sbin/modprobe --ignore-install snd-emu10k1 && /sbin/modprobe snd-emu10k1-synth After that, I am able to /etc/init.d/alsasound stop successfully ! When trying to start it again, it says this: # /etc/init.d/alsasound restart Shutting down sound driver: done Starting sound driver: snd-hda-intel done /usr/sbin/alsactl: load_state:1236: No soundcards found...
