[MPlayer-users] Cache empty, consider increasing -cache and/or -cache-min. [performance issue]

[Jim Cross]

I have compiled and can run SVN-r37303-4.6 (thanks for your help Erik.). I
have not yet run make install to create the simlink as I want to make sure
the new version works OK. So for now, I can still run my current (old) ver
and the new one fairly easily.

However, I can't find how to setup the audio for the new version?
The error shows:
"[AO OSS] audio_setup: Can't open audio device /dev/dsp: No such file or
directory
Failed to initialize audio driver 'oss'"

The old version uses the directory '/dev/snd/' to find the audio device.
Don't know how to setup or change the new version...

Also, the old version I use Alsa driver which is listed using '-ao help'
but the new version does not list this driver. I tried './configure
--enable-alsa' but don't know if this is valid and anyways it didn't work,
should it?
So I am not sure if using the oss will work until I can fix the 'Can't open
audio device /dev/dsp: No such file or directory'.

Just for completeness:
~/mplayer/mplayer -ao oss http://ai-radio.org:8000/radio.opus
I get 'Starting playback...' - obviously this will be video only. However,
it's only a RPi so I get the "Cache empty, consider increasing -cache
and/or -cache-min. [performance issue]" errors - the good news is I'm not
interested in video.... So:
~/mplayer/mplayer -novideo -ao oss http://ai-radio.org:8000/radio.opus
However, no sound (and no video) = does not play :(
