trying to use Boss Micro BR-80 as USB soundcard with Jack but seems like jack (qjackctl) does not recognize it. My system: Ubuntu 13.04 with pretty much standard configuration (runs pulseaudio, installed jackd2, pulseaudio-module-jack, qjackctl) Have built in audio that I don't really plan to use with jack (or at least not in initial setup where I am just trying to make something work): 00:01.1 Audio device: Advanced Micro Devices [AMD] nee ATI Wrestler HDMI Audio [Radeon HD 6250/6310] 00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) (rev 40) Boss Micro BR-80 seems to be recognized properly (see below) 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. Any ideas why it does not work or how to troubleshoot it further? When I plug BR-80 in I get (output of usb-devices): T: Bus=08 Lev=01 Prnt=01 Port=01 Cnt=02 Dev#= 3 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=ff(vend.)
