Hi list,
My graphic card is connected through HDMI to my screen. I get no sound,
and no error messages: sounds seem to play correctly, according to
software, but I hear none. As if something was muted, though I checked
alsamixer ten times and activated everything I could.
I use a debian wheezy up to date. On the same computer, but a different
OS (Ubuntu 10.04), sound works. I may have changed something to make it
work, but I don’t remember.
>From aplay -L, AFAIU, alsa recognises three cards, namely default (plays
to pulseaudio), some ATI SB card and my Radeon card that I want to make
work.
When I play to the Radeon card (using aplay -vv -D
"plug:'hdmi:CARD=Generic,DEV=0'") I hear no sound, though everything
seems to work.
When I play to the other sound card ("sysdefault:CARD=SB"), connected to
analog headphones, it works.
When I play to the default card, I can see through pavucontrol that
pulse audio receives sound, but I can hear nothing.
alsa-info is at
http://www.alsa-project.org/db/?f=10570aee7a643a6a7a6e0ac2f44918d834133312 . Below, some supplementary details.
Any idea what I could try? Or where I could look for differences which
may explain why it works on Ubuntu and not on Debian?
Olivier
