[alsa-devel] [git pull] [PATCH 0/7] add support for many Roland and Yamaha devices

I thought I would test the other Roland device I have, the BR-80. FYI I have 
pasted the debug log further down. I will add that this used to work before 
the refactoring.

The device shows up in aplay and arecord:

card 3: BR80AUDIO [BR-80(AUDIO)], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

It does NOT show up in amidi. In this case it should show a MIDI output which 
represents the drum sequencer which it used to.

Also, I cannot get any input or output from the device. If I try to record, I 
get nothing:

$ arecord -Dhw:3 -fS32_LE -c2 -r44100
Recording WAVE 'stdin' : Signed 32 bit Little Endian, Rate 44100 Hz, Stereo
RIFF$�WAVEfmt D�  data�arecord: pcm_read:1801: read error: Input/output error


If I play I get this:

$ aplay -Dhw:3 -fS16_LE -c2 -r44100 Test.wav
Playing WAVE 'Test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono
aplay: set_params:1081: Sample format not available
Available formats:
- S32_LE

$ aplay -Dhw:3 -fS32_LE -c2 -r44100 Test.wav
Warning: format has changed to S16_LE
Playing WAVE 'Test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono
aplay: set_params:1081: Sample format not available
Available formats:
- S32_LE

In this case there's clearly a format issue, but the device only records 16 
bit and used to cope with S16_LE files
