I tested this with the BR-80. Logfile at the end.

It lists the devices OK:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
...
card 3: BR80AUDIO [BR-80(AUDIO)], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0


$ arecord -l
**** List of CAPTURE Hardware Devices ****
...
card 3: BR80AUDIO [BR-80(AUDIO)], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0


$ amidi -l
Dir Device    Name
IO  hw:3,0,0  BR-80(AUDIO) MIDI 1


The bad news I can't get either the sound output or input to work:

$ aplay -Dplughw:3 testtone.wav 
Playing WAVE 'testtone.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono

This doesn't do anything and I have to CTRL-C to exit

$ arecord -Dplughw:3
Recording WAVE 'stdin' : Unsigned 8 bit, Rate 8000 Hz, Mono
RIFF$�WAVEfmt @data�

That doesn't do anything further.

I also cannot get jack to connect to it with any normal settings:

failed. - Unable to connect to server. Please check the messages window for 
more info.
Cannot connect to server socket err = No such file or directory
Cannot connect to server socket
jack server is not running or cannot be started

I do wonder whether a quirk is still needed for this device. It seems to be 
reporting as a 32-bit interface when it's actually only 16-bit, and I suspect 
this might be upsetting things.


Cheers,

Keith
