[Bug 480103] Re: Alsa not working while jackd is running

OK.  I understand now.  ALSA is working fine, but totem isn't able to
get to the output channels.  More specifically, jack is controlling the
card directly, so other clients cannot use it.  Totem may be attempting
to send data to alsa, or to pulseaudio, or to gstreamer, or even to
xine, depending on how it is configured.  None of these will allow it to
access the sound card controlled by jack.

The workaround for now is to use two audio interfaces: have JACK control
one, and leave the other for general sounds (probably managed through
pulseaudio).

In the future, it may be that JACK interfaces for gstreamer or
pulseaudio can be built that would allow this to work.

I'm marking this "Won't Fix" against the jack-audio-connection-kit
package, as there is nothing in JACK that will change to support this
feature.  There are outstanding bugs to address some of these issues,
but they may not completely address them (needs testing), and in any
case, are not yet available.

If this issue persists in 10.04 after release, please file a new bug
against totem (or other specific affected software) requesting that they
be made to work with JACK.
