What kernel and what version of Alsa are you using?

I don't think that the problem has any thing to do with mplayer. I think
that Audiophile/Alsa 1.0.1/Linux 2.4.24 cannot handle 48 kHz data.
My mplayer will play movies with 44.1 kHz sound without any problems.
It will also play wav files at 88.2 kHz, 96 kHz, 44.100 kHz, 32 kHz,
24 kHz and 22.05 kHz. Only 48 kHz data fails with very choppy sound
and lots of these messages
alsa-play: xrun of at least 1.010 msecs. resetting stream
alsa-play: xrun of at least 0.888 msecs. resetting stream
Alsaplayer gives much the same results. If you give it the -F 48000
option the sound is very choppy. -F 22050 and -F 44100 work. -F 96000
is refused with the message "frequency out of range (8000-48000)".
(I think that alsaplayer always resamples to a bit rate which is
44.1 kHz by default and can changed with the -F flag.)
Does anybody know why 48 kHz sound fails?

thanks, that works.
Is it possible to configure the Audiophile and Alsa so as to send different audio
to the RCA and headphone outputs?
