Hi all,
I apologize if this is the wrong way of contacting the ALSA project. but I am
not really clear how to approach this after consulting the wiki.
After adding a HD-Graphics-card and a HDTV set to my VDR-Mediacenter I tried to
switch from DVB-Out (SD analog incl. audio) to HDMI incl. Audio via xinelibout.
So far video works fine, but there is no audio. I started with several of the
distributions (yaVDR based on Ubuntu 10.4, easyVDR based on Ubuntu 8.04 and
varios other ways, incl. building a system scratch via Gentoo) but always run
into the same issue.
Either the sound-portion of the ASUS Bravo 220 (which carries an NVIDIA GT 220)
is not detected at all, or - after playing with the modprobe.d parameters there
are 4 or 1 device - but no audio.
Unfortunately I have no other HDMI TV Set or receiver to exclude that the Sony
is the source of error, but I can say that with my XBox360 I get perfect sound
via HDMI, so basically the TV set is not broken, nor are the cables.
I have run alsa-info.sh and the output is here:
http://www.alsa-project.org/db/?f=ccaba18e12c044e4cb7d675147592de788261cdd
What jumps right into my eyes is this in dmesg after the TV set has been
detected, but I have no clue what it could mean ...
(note there is another ALC662 onboard device, which does work via analog
Front-Output when I run speaker-test)
Now, if I run speaker-test for hdmi:CARD=NVidia or on one of the 4 hdmi-devices
(-Dplughw:0,x) , I either get nothing or this:
r...@video:~# speaker-test -Dhdmi:CARD=NVidia
speaker-test 1.0.23
Wiedergabe-Gerät ist hdmi:CARD=NVidia
Stream-Parameter sind 48000 Hz, S16_LE, 1 Kanäle
Verwende 16 Oktaven rosa Rauschen

So, I am really happy for any kind of hint what to do now. A pinpoint to the
right the documentation pages would be great, also I am capable of basic C
knowledge, so I am also happy to compile and test things...
Any response is appreciated.
Kind regards,
Alex D.
