"-ac" selects the number (amount) of audio channels to output, as in
"stereo to mono". I'm not even sure it applies to ffplay. And "-ac 0"
doesn't make sense in that context.
If you want to select a different audio *stream* to play (please note
the semantic difference between channels and streams), you need to use
the "-ast" option:
-ast stream_specifier select desired audio stream
You can also cycle through the available audio streams interactively at
run time by pressing the 'a' key.
