I have trouble playing a movie with 7-channels FLAC audio with stereo output. Seems to me like it doesn't convert the stream to 2-channel - I only hear some background sounds and music, but not a car passing by or 99% of characters speaking.
As I know, mplayer sets channel count to 2 by default, but I've tried forcefully making "-channels 2". I also tried "-af pan=..." with different numbers. Maybe I did it wrong.
This is mplayer's output:
| Code: | $ mplayer -channels 2 Anime/Evangelion_1.11_-_You_Are_\(Not\)_Alone_\[3xR\]\[Blu-ray.1080p.H264.FLAC\]\[2B6AC996\].mkv
