This is not correct, it will create problems with files that contain both audio
and video.
I actually don't think the problem is in MPlayer at all - the errors in the
Video & Audio case actually look to me like your audio driver are going into
suspend mode.
Things I would suggest to try:
1) updating ALSA drivers
2) Trying ALSA's OSS emulation via -ao oss.

None observed.

driver are going into suspend mode
Yes it is. It looks like this:
preempt_disable();
for_each_pci_device -> suspend();
things need to be done
for_each_pci_device -> resume();
preempt_enable();
1) updating ALSA drivers
I will try. I'm using alsa build into kernel 2.6.16.

It looks like MPlayer can't handle error from Alsa. But under normal conditions
such error will not occur. Sorry to bother You.
aplay - same good behaviour as for mplayer with video & audio - "Reseting
soundcard".
And after Ctrl+C mplayer displays: interrupted in module audio_play.
