I've had problems when switching from Jokosher to Totem to play an Ogg.

Totem appears to be playing normally but does not produce any sound.
If I close Jokosher then you can hear totem.

I've also had a problem when trying to playback sound within jokosher
after switch from another app (I think it was xmms). I get a dialog
with the following text:

     Argh! Something went wrong and a serious error occurred:

     Resource busy or not available.

     gstalsasink.c(636): gst_alsasink_open (): /timeline/playbackbin/
     alsasink0:
     Device 'hw:0' is busy

After closing and reopening Jokosher, i got the same error again.
After logging out of gnome and logging in again - I still got the same
error message.

I had to restart!

Is there some way to reset alsa or the device driver - with out having
to restart?

Running on Ubuntu - with Jokosher 0.2 runscript.
