[MPlayer-users] SDL/aRts audio driver fails

[brep068gw001 at sneakemail.com]

I have more info to add to this:

It's strange that 'artsdsp mplayer -ao oss FoodRace2.avi' doesn't work,
because I can run 'artsdsp play xyz.wav' and that works perfectly. 
Since mplayer thinks my sound device is busy when I run it through
artsdsp, my guess is that mplayer is bypassing artsdsp's sound
redirection and still trying to use the real OSS device directly.

I tried running ESD and then 'mplayer -ao sdl:esd FoodRace2.avi,' and
that works fine.  Also, 'mplayer -ao sdl:oss FoodRace2.avi' works fine
when I have no sound server running, and same with 'mplayer -ao oss
FoodRace2.avi'.  It seems that the only problem is with '-ao sdl:arts'.

I've also tried enabling network transparency in the aRts server then
trying mplayer, but it makes no difference.

Has anyone else had such problems with aRts before?  I searched the list
archives and couldn't find anyone who had a similar problem.

Thanks for any help you can give me.
