Hi,
I have a debian sid desktop with an onboard soundcard working, a
logitech c905 webcam working and a amd hd6450 (caicos) graphik card. The
latter is connected to a samsung t240HD monitor via a hdmi cable. I have
failed so far to connect the sound to the monitors speakers - it is
without loud saying that these work flawlessly under win7.

Opening gnome-alsa-mixer I get three tab:
Realtek ALC888 | USB mixer | ATI R6xxx HDMI
The latter does not have any sliders. Using alsamixer I unmuted this
device to no success, however, the settings remain at 00 instead of MM
and cannot be upregulated to 50 e.g.
What do I have to do to get sound in the speakers?
I have been using lately ubuntu and changed back to debian for !! lack
of support for my graphic card in ubuntu.
I am the admin of my desktop and can adjust almost everything. I only
have to know _where_ to tune.
Greetings
Bernhard
