[linux-audio-user] Edirol UA-25: Any issues?

[Cesare Marilungo]

I can get 11ms without issues or 5ms (sometimes even less when the setup 
is simple) with this card. But on some distros I had to disable my 
ethernet adapter. Are you sure you don't have some heavy process or 
server running?
Also, I load the realtime module with the parameter any=1. I know this 
could be less stable, but its worth if you need to record your music 
without interruptions and with a low latency.

p.s. Please guys help me with my UA-20. :-(
