Hi,
My audio card is intel HDA. I set card profile to
output:analog-sorround-51 so that 5.1 streams can work.
But I also want front-left channel go to real-left speaker and
front-right go to rear-right when I playback a stereo audio stream.(with
playbin2 which use pulsesink)
But during my experiments, for a stereo audio stream, only front-left,
front-right, front-center speaker had output.
I checked the calc_map_table function in resampler.c, I realized this
behavior seemed by the implementation.
So, to achieve my purpose, either I:
1. change the resampler.c source code. Or
2. use some gstreamer plugin to mapping stereo stream to a 5.1 stream
before pulsesink.
Any hints or correction?
Thanks a lot!
Cheers.
Long
