otro problema con mplayer!!!

[nad]

hola, tengo problemas con el sonido con mplayer, mira que me encanta esta aplicación, pero ahora me da este error, lo he sacado por la consola:

************************************************
**** Your system is too SLOW to play this! ****
************************************************

Possible reasons, problems, workarounds:
- Most common: broken/buggy _audio_ driver
- Try -ao sdl or use ALSA 0.5 or the OSS emulation of ALSA 0.9.
- Experiment with different values for -autosync, 30 is a good start.
- Slow video output
- Try a different -vo driver (-vo help for a list) or try -framedrop!
- Slow CPU
- Don't try to play a big DVD/DivX on a slow CPU! Try -hardframedrop.
- Broken file
- Try various combinations of -nobps -ni -forceidx -mc 0.
- Slow media (NFS/SMB mounts, DVD, VCD etc)
- Try -cache 8192.
- Are you using -cache to play a non-interleaved AVI file?
- Try -nocache.
Read DOCS/video.html and DOCS/sound.html for tuning/speedup tips.
If none of this helps you, read DOCS/bugreports.html.

haber si me podeis echar una mano, he entrado en las opciones y he configurado el driver de sonido, pero sigue igual, que puedo hacer??????????

salu2.
