No, I am not talking about clipping. The problem happens regardless of volume.
If I run "speaker-test -c2", both speakers have sound output at the same time (which should not happen).
The "constantly swapping" does not always happen-it happens at random, and only on some of my audio files. I do not know what caused it.
Some observations when I adjust the volume in "alsamixer" and run "speaker-test -c2" (it seems that the swapping problem does not happen):
L=0, R>0: Both have constant sound on "Front Left", Both have no sound on "Front Right". (No, this is not a typo)
L>0, R=0: Both have no sound on "Front Left", Both have constant sound on "Front Right".
L>0, R>0, L>R: Both have constant weak sound on "Front Left", Both have constant strong sound on "Front Right".
