Are you sure of that? IIRC, lswr is perfectly capable of dealing with unknown channel layouts. You have to provide the channel count, of course. > what 1 channels but 0 channel_layout means It means 1 channel, but we do not know which one, it may be the left channel of a stereo stream that was split, or more or less anything.
