This is how I send mplayer output to my TV:

/usr/bin/xinit /usr/bin/xterm -ut -e $HOME/bin/$PROG \
             $MOVIE -- /usr/bin/X :1 -layout TV &

With F8, I get not sound at all, unless I execute the above command as root.
Then I created an audio group for myself and added to
/etc/security/console.perms.d/50-default.perms:

# roma
<sound>=/dev/dsp* /dev/audio* /dev/midi* \
        /dev/mixer* /dev/sequencer* \
        /dev/sound/* /dev/beep \
        /dev/snd/* /dev/adsp*

.....

# roma
<console> 0660 <sound>       0660 root.audio

This allows me to get sound without being root (even logged in
remotely in a console).

I know that, and a like it very much.

Yes. It works for xmms. I tried to contact the audacious team via IRC,
and they said: "roma, I really do not care"

I tried, yesterday, the latest version, 1.4.2, and got the same result.

Yes. But it also works fine with ESD.

xine and gxine do not work with pulse plugin (the connection is lost after a few
seconds), but totem does (it is based on xine, right?). What is the difference?

I use a self compiled version of xine and gxine with all of the codecs
enabled, and
I have no problem using them with the ESD plugin. Pulseaudio works
just fine this way.

There is a slight hiccup (missing of sound) from time to time.
It is very fast,and it does not seem to be related to the amount of
processing on my computer: Core 2 duo, 2.1GHz, 2GB ram, x86_64, F8

Thanks.
