[linux-audio-user] Ubuntu, ALSA, and the Roland UA-100

[smetoyer at comcast.net]

Hey everyone...  I'm a bit of a linux newb, so please bear with me.  I'm using Ubuntu and attempting to get a Roland UA-100 setup with ALSA.

The driver appears to load ok, however aplay will hang when trying to play any wave files (doesn't play any sound, has to be forcibly ended). Attempting to test in the Multimedia Systems Selector results in the 'Failed to construct test pipeline for Alsa' message.  qjackctl actually starts Jack ok, but pressing the play button on the transport will not start it (it immediately flashes back to stopped)...

Here's the results of aplay -l:

card 0: UA100 [UA-100], device 0: USB Audio [USB Audio] Subdevices: 0/1 Subdevice #0: subdevice #0


and the results of lsmod | grep snd:

and a cat /proc/asound/cards:

Am I overlooking something simple?  TIA for any help getting this thing working!
