yes, "aplay -f dat < /dev/video24" works correctly.

as far as sox goes:

~]# sox -tossdsp -swr48000 -c2 /dev/video24 /data/rec/soxtest.wav
sox: Failed reading /dev/video24: Unable to reset OSS driver.  Possibly 
accessing an invalid file/device

what is wrong here?


(as far as mplayer: haven't been able to compile it on my FC4; "make" breaks at 
' libpostproc/postprocess.o' and 'libavcodec/libavcodec.a' and 
'libavcodec/libavcodec.a', but, i suppose, that's not on-topic.)

thanks. Will look when mplayer is functioning.
