[alsa-devel] Echo Audiofire 12 issues

[Adriano Michael Petrosillo]

When I start Ardour, for example, which employs the ALSA driver 
(optionally through JACK), it is able to employ the audio interface for 
a while but this will invariably and eventually result in a string of 
buffer under-runs, at which point the DAW automatically disengages from 
using the audio interface. Any attempt to reconnect to the interface 
results in a segfault. I realise this may appear to be a fault in 
Ardour itself but there are no such issues with the regular onboard 
interface. If you want I can run some tests, but you'll have to guide 
me through it.
