Hi
I have an old Mbox (original version) that I'd love to get working. There are
quite a few of these still around as they were the default low-end device for
Protools, and as there are no 64-bit windows drivers around there are lots of
them acting as paper-weights. If they just worked in Linux out of the box, it
might persuade a few people out there to take the plunge :)
I have a bog-standard HP Pavilion desktop running Fedora 19. There are 4
(USB2?) ports at the back and one USB3 at the front. Plugging the device into
any of the back ports doesn't work at all, I get this:

And I guess because of the dreaded usb_set_interface failed, it doesn't show up
in the phonon/gstreamer device list. This is the lsbusb output:

Then if I plug it into the front USB3 port, it almost works. I get the device
recognised and installed just fine:

If I set the device in phonon and try to play some music through amarok for
example, I get glorious sound using either the spdif or analog outputs. The
improvement over the back-of-the-computer minijack sound is really amazing :)
But (there's always one of these), about 50% of the time the music cuts out and
I get random white noise. I also get these, although they don't seem to
correspond to the 'white-outs':
Jul 9 09:21:35 localhost pulseaudio[1086]: [alsa-sink] alsa-sink.c: ALSA woke
us up to write new data to the device, but there was actually nothing to write!
Jul 9 09:21:35 localhost pulseaudio[1086]: [alsa-sink] alsa-sink.c: Most
likely this is a bug in the ALSA driver 'snd_usb_audio'. Please report this
issue to the ALSA developers.
Jul 9 09:21:35 localhost pulseaudio[1086]: [alsa-sink] alsa-sink.c: We were
woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or
another value < min_avail.
The output of also-info is here: http://pastebin.com/7ufuuwgM. It's is
->this<- close to working, can anyone help? It was like this under Fedora 18
as well btw, same symptoms.
