Re: xmms redirection to stdout

Hi,

I may have caused some confusion by a typo:
I meant
	xmms -audioout - | a2play <mybdaddress>
instead of
	xmms -audioout - | aplay <mybdaddress>

a2play is a tool that comes from the bluetooth-alse project to redirect
output to a stereo headset.

a2play works with mpg123 --au - file.mp2 | a2play <bdaddress>

but I have not managed to get a2play to work by reading from a device or
file other than stdin, even though the program's help claims it could do
so.

Therefore I would like xmms to send the raw data to stdout so that I can
catch it with a2play.

I've been asked to test a stereo bluetooth headset with linux, and I have
been trying to get it to work for more than the day now. It only works via
this piping from mpg123 to a2play so far.

Any comments and help are GREATLY appreciated.

Thanks a million,

Tim
