Public bug reported:
SG41J1 barebone has rear and front audio outputs. While the front output
works out of box, the rear output (that is more convenient to connect to
the speakers) only works after applying the series of hacks, as
described in http://ubuntuforums.org/showthread.php?t=1618138.
This bug likely should not be considered "solved" as even hda-verb is
not available in the Ubuntu repository and must be googled on a web to
download. At least, I propose to include hda-verb but surely would be
better to have some better fix.
sudo hda-verb /dev/snd/hwC0D0 0x0d SET_CONNECT_SEL 0
restores the output immediately.
The rear output works immediately and out of box under Windows 7.
