Comment (by reimar):
I don't think it skips it by intention, it is just that there is probably
a lot of audio data already demuxed and buffered for the enabled and in-
use stream.
When switching to a different audio stream, demuxing of that will only be
enabled at that point.
ffplay has now the two options of either continuing to play the old stream
until it gets data from the new one (annoying and complex to implement) or
just to drop the audio for the old one and start playing the new one even
though the first data for that is several seconds in the future.
