Bug#970137: ardour: Ardour doesn't record anything with usb micro

[david <brometeo@gmail.com>]

Package: ardour
Version: 1:6.2.0+ds1-1
Severity: normal

Dear Maintainer,

I have acquired a usb micro for recording some music. Trying to use with arecord it works perfectly. In fact, a simple:

  arecord -f dat example.wav

makes the trick for me with good quality.

I have installed arcour for using a proper DAW. The initial configuration I have set is ALSA, setting input device to my usb micro. When I arm a track for record and triger recording nothing happens. The source seems not been recognized. I don't know how to proceed with this issue. Micro works, usb works, recording with other tools works. Only Ardour doesn't work, but ir seems to recognize the device on configuration stage.

Thank you for any clue.
