That's ok, it supports everything I need it to play which is DSD and

I tried to use the PCM output from mplayer but it creates a file in the
current directory rather than playing it. And I suspect this won't work
for DSD since it is not PCM based.

Could you suggest the correct command line options to send the PCM
stream to the default device?

Thanks
