[Pkg-alsa-devel] Bug#635694: alsa-base: alsa bug 0005418: snd-hda-intel: alsa force-reload required to avoid Dummy output

[r.ductor]

Package: alsa-base
Version: 1.0.23+dfsg-4
Severity: important

After my last 2 full-upgrade to kernel 2.6.39-2-amd64 (2011-07-26 and 2011-07-28) no sound.
I notice that kmix shows Dummy output.
If I do alsa force-reload sound works (and Kmix mentions Internal Audio Analog Stereo).

Please have a look at my bug report at alsa for more details:
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=5418

I report also here because it might be a global problem (for some reason Dummy is preferred to Internal Audio).
