Hi,
I am using OSS. When I start "mplayer -ao oss -channels 6" I get nice
surround sound. I have also installed OSS Virtual Mixers. Strange enough
I do not manage to get mplayer to use other dsp devices e.g. "% gmplayer
-ao oss:/dev/dsp5 -channels 6" and xmms at /dev/dsp7 give a conflict
when using simultanously:
%xmms
** WARNING **: oss_open(): Failed to open audio device (/dev/dsp7):

dsp0: pid 915 cmd 'firefox-bin' IN OUT
dsp0: pid 915 cmd 'firefox-bin' IN OUT
dsp0: pid 1021 cmd 'mplayer' OUT
and when I run xmms alone at /dev/dsp7 the history shows:
dsp0: pid 915 cmd 'firefox-bin' IN OUT
dsp0: pid 1021 cmd 'mplayer' OUT
dsp7: pid 1028 cmd 'xmms' OUT
I can also use the device simultanously (so I hear two sound at the same
time, e.g. xmms and ossplay):
dsp4: pid 1054 cmd 'ossplay' OUT
dsp7: pid 1047 cmd 'xmms' OUT
dsp4: pid 1054 cmd 'ossplay' OUT
So I know I the mixers work but how I can force mplayer to use /dev/dspX
instead of /dev/dsp that blocks the mixers?
