Ok, on a reboot (and working sound), it says root@michis-toshiba:~# dmesg | grep -i hda [ 8.891550] snd_hda_intel 0000:00:1f.3: enabling device (0000 -> 0002) [ 8.983225] snd_hda_intel 0000:00:1f.3: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915]) [ 9.036758] snd_hda_codec_conexant hdaudioC0D0: CX20753/4: BIOS auto-probing.

So no difference it seems. After a rmmod -f snd_hda_codec_conexant modprobe snd_hda_codec_conexant again, sound does not work anymore. dmesg says: [ 253.530739] snd_hda_codec_conexant hdaudioC0D0: CX20753/4: BIOS auto-probing. [ 253.531366] snd_hda_codec_conexant hdaudioC0D0: autoconfig for CX20753/4: line_outs=1 (0x1d/0x0/0x0/0x0/0x0) type:speaker [ 253.531370] snd_hda_codec_conexant hdaudioC0D0: speaker_outs=0 (0x0/0x0/0x0/0x0/0x0) [ 253.531374] snd_hda_codec_conexant hdaudioC0D0: hp_outs=1 (0x16/0x0/0x0/0x0/0x0) [ 253.531377] snd_hda_codec_conexant hdaudioC0D0: mono: mono_out=0x0 [ 253.531379] snd_hda_codec_conexant hdaudioC0D0: inputs: [ 253.531383] snd_hda_codec_conexant hdaudioC0D0: Internal Mic=0x1a [ 253.531386] snd_hda_codec_conexant hdaudioC0D0: Mic=0x19 [ 253.536530] input: HDA Intel PCH Mic as /devices/pci0000:00/0000:00:1f.3/sound/card0/input23 [ 253.536677] input: HDA Intel PCH Headphone as /devices/pci0000:00/0000:00:1f.3/sound/card0/input24 [ 253.536825] input: HDA Digital PCBeep as /devices/pci0000:00/0000:00:1f.3/sound/card0/input22 How can I debug this further?
