Aufgrund dieses Outputs schliesse ich, das das passt.
hm. An und für sich kann man ja tcprobe meistens vertrauen.
Jedoch: Ich habe ähnliche Symptome wie Du, wenn ich eine falsche audiorate
einstelle. Bei mir kommen nur 32000 aus der analogen Karte, und wenn ich
behaupte das wären 48000 laufen die Bilder extrem hackelig und man hört
Mickey-Maus-Stimmen. Nach einer gewissen Zeit kommt dann auch mplayer's
Meldung:

************************************************
**** Your system is too SLOW to play this! ****
************************************************
Possible reasons, problems, workarounds:
- Most common: broken/buggy _audio_ driver
- Try -ao sdl or use the OSS emulation of ALSA.
- 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 some of the lavdopts,
e.g. -vfm ffmpeg -lavdopts lowres=1:fast:skiploopfilter=all.
- 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/HTML/en/video.html for tuning/speedup tips.
If none of this helps you, read DOCS/HTML/en/bugreports.html.

mit audiorate=32000 ist alles so wie man es sich wünscht.
Das nur nochmal so. Ansonsten habe ich momentan nichts anderes mehr im Bauch,
leider ...
