[MPlayer-users] Audio-switching on 6-channels crashes MPlayer

[Alexander Roalter]

I'm using a fairly old dev-SVN-r18689-Mplayer, and have still to test it 
with a new one (still compiling does make a lot of problems on my 
crippled system - time to set it up right...), but I'm quite sure this 
hasn't gone away.

I'm using -channels 6 and -af channels=6 to always use 6 channels (and 
muting the unused ones, as with not doing so, stereo is played back on 
the rear speakers...)

When I switch the language using the '#' in movies, I get the following:

8:<

[channels] The number of routing pairs must be between 1 and 6. Current

Exiting... (Fatal error)

Is there something else I have to set up? is there a way to set up these 
`routing pairs'?
