I installed totem-xine on a zx2000 with Fortemedia QS3000Am, 2.6.14-rc2 and everything seems fine. Usually I use beep-media-player with the ALSA output plugin and it "just works". > More generally, I'm a little confused with the ALSA sound subsystem.

Is this normal? Should I also install > gstreamer0.8-alsa? Or gstreamer0.8-oss? Or both? Yes, this is to be expected. /dev/dsp comes from the kernel OSS support; with no OSS support it won't work. Native ALSA devices are something like /dev/snd/[blah]. ALSA OSS emulation is a kernel driver that presents a /dev/dsp that looks like an OSS device to the program, but actually uses the underlying ALSA system to output sound. It was made so that old programs that only know about OSS can still work as you transition to ALSA. alsa-oss appears to be a userspace program that wraps another program to do a similar thing (i.e. "fool" the program into thinking /dev/dsp is there), although I've never used it. -i
