What do you mean by non-audio stream?
The passthrough of AC3 stream or so.
Can you give specific commands which should work?
I usually test using ac3dec program included in alsa-tools.
Tried ac3decode, and got a perfect sound out. I am using the following asound.conf (if it is relevant):
Well, I guess this won't be a non-audio mode. Try to get the latest alsa-tools git tree. I changed ac3dec and now it has -H option. Specify this together with -C,
% ac3dec -C -H foo.ac3This will be the AC3 passthru testing.
This is the only one that works:
./ac3dec -R --hdmi /tmp/ac3_the_other_side_48khz.ac3 5.1 Mode 48.0 KHz 640 kbps Complete Main Audio Service Using PCM device 'plug:hdmi:{AES0 0x0 AES1 0x82 AES2 0x0 AES3 0x2}'
-P and -C give me a strange mewling..
BTW, -H does not work, only --hdmi.
http://git.alsa-project.org/http/alsa-tools.git cd alsa-tools make
results with a ac3decode without an H option. HEAD: 8a3b9b29010669c085f1821ebc6b6a2672d8d93a which is date to 9/9
Oops, I seem to have forgotten to push. Pushed out now.
Cheers, Nir.
