Public bug reported:
Hello!
Sound worked correctly as long as used a DVI cable for my monitor and
the analog output of the sound card. Then I connected a second screen to
my PC using both a DVI and a DPORT cable and the sound output of the
DPORT. The sound frequently does not work after rebooting the PC. In
about 10% of the reboots the sound works correctly, in about 90% there
is no sound at all.
I am using ubuntu 11.10.
Kind regards
piechan
