[MPlayer-users] Strangeness with audio balance

[David Woodfall]

On Sunday 13 May 2018 23:51,
Dave Woodfall <dave at dawoodfall.net> put forth the proposition:
>Hi
>
>I was trying to get balance to work with -slave and a fifo today, but
>was finding that even though it appeared to be set (looking at
>get_property) it wasn't doing what I normally expect a balance
>control to do.
>
>After that I tried playing some files normally, without a fifo, and
>found the same problem (using '(' and ')').
>
>When adjusting the balance all the way down, which ought to mean that
>sound only comes out of my left speaker, it cut out /some/ sounds (eg
>an electric guitar), but the remaining audio was still in stereo.
>
>I found this happens using both alsa and jack outputs. The files I
>tried were 2 channel mp3s - proper stereo, not joint stereo.
>
>Any ideas why this is?
>
>MPlayer SVN-r38101-5.5.0
>
>Thanks for any ideas.

Oh I forgot to mention that I've been reading the slave doc here:
