It seems my sound card takes time to be initialised. `dmesg` shows me a lot of lines with: "hda-intel: spurious response". After that I have this line: "hda_intel: azx_get_response timeout, switching to single_cmd mode" and then a lot of lines with this message: "hda-codec: out of range" Note that the sound work but it's a bit annoying because ligthdm is frozen until the sound works...
According to this document:
=> http://www.mjmwired.net/kernel/Documentation/sound/alsa/HD-Audio.txt#81
It seems that it's a knowing bug but how can I help to fix it? :)
WORKAROUND: I can load snd-hda-intel module with this option:
probe_mask=0x103
or by adding this line in /etc/modprobe.d/alsa-base.conf :
options snd-hda-intel probe_mask=0x103
I still have no sound at start-up (the first 30-40 seconds) and I still have a lot of errors messages with dmesg but now lightdm is no longer frozen for a few time.
