Check permissions, Myth uses more devices that xmms, so some may not
be set up with right permissions. You did not say what distribution
you use, but you need to configure it to change permissions of the
following devices (probably an overkill, but this will get everything

/dev/dsp* /dev/audio* /dev/mixer* /dev/sound/* /dev/snd/* /dev/sound

If you have /etc/security/console.perms file (RH-derived distros do),
then that's where it is setup, make sure <sound> group includes these
devices. I usually change their permissions to 0666 so I can use them
even if I log in remotely to test stuff.
