card 2: BR80AUDIO [BR-80(AUDIO)], device 0: USB Audio [USB Audio]
Boss Micro BR-80 seems to be recognized properly but qjackctl does not
list it in Set under any of Interface, Input Device, Output Device
choices, I only see /dev/dsp, /dev/audio, plughw:0 and hw:0.
"hw:2" should appear in those lists. Did you start QjackCtl before
plugging the device in? Can you start Jack manually with
"jackd -d alsa -d hw:2"?
started qjackctl after the device was plugged in,
starting jack manually seems to be working (also tested wiuth
ardour2, both recording and playback works).
Does that mean there is a bug in qjackctl? Using the version in
Ubuntu 13.04 which is qjackctl 0.3.9-2
Here's what jackd prints out when started manually:

created the bug above, turns out there is a way to make qjackctl work
but it involves clicking on the mysterious '>' buttons next to the
dropdowns (the dropdown menus in question are: Interface, Input Device,
Output Device in the Setup dialog)
The tooltips for '>' buttons do not explain much (they seems to be
pretty much the same as tooltips for dropdowns.
Details in the bug, here's the summary of what the tooltips say and
what the menus (dropdown and '>' buttons) offer:
Interface dropdown tooltip: 'The PCM device name to use'
Interface '>' tooltip: 'Select PCM device name'
Input device dropdown tooltip: 'Alternate input device for capture'
Input device '>' tooltip: 'Select input device for capture'
Output device dropdown tooltip: 'Alternate output device for playback'
Output device '>' tooltip: 'Select output device for playback'
The values for all dropdown menus are:
- (default)
- /dev/dsp
- /dev/audio
- plughw:0
- hw:0
The values for all '>' menus:
- hw:0 HD-Audio Generic
- hw:1 HDA ATI SB
- hw:1,0 ALC892 Analog
- hw:2 BR-80(AUDIO)
- hw:2,0 USB Audio
- (default)
Anybody knows what's going on here? Pointers to explanations? Why are
there TWO list of devices to choose from?
thanks!
