Maybe:
mplayer media.avi -channels 1
?

Once I downloaded a movie with only right sound channel. Then I used mplayer with this command to normally watch it.

Bump!

There must be some way. I''m using amarok, alsa and needs mono output, but nothing is working.

Finally!

To get mono output (guitar amplifier as speaker ) on Amarok with ALSA do the following -

- add

pcm.mono {
   type plug
   slave {
      pcm default
      channels 1
   }
   route_policy average
}

to ~/.asoundrc
- restart ALSA (/etc/rc.d/alsa restart)
- change stereo output in Amarok from default to mono

This should be much easier

AFAIK you can't use amarok1 instead.

Hi, I can do this with mplayer...

Command Line :
mplayer -af pan=2:1:1:1:1 test.mp3

GUI (using SMplayer) :
Preferences > Advanced > Option for MPlayer.
Type this option in 'Audio filters' box :
pan=2:1:1:1:1

Ow, the option overlouds the sound, this option is better :
pan=2:0.5:0.5:0.5:0.5

- restart ALSA (/etc/rc.d/alsa restart)

Not necessary. Just edit ~/.asoundrc, and restart the sound-using app.

Re: is there a way to force mono sound output?

Depending on your needs, a complete different aproach to the situation is to use jack. Most applications work well with jack, and the ones that don't can also be redirected to jack. Sound that goes through jack can then be routed/manipulaed as you wish.
