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
