Something strange is happening to my edirol audio usb interface: when
the pc is booting up I can hear an annoying noise coming from the
interface (I mean on the outside, not from the jack). The hiss stops
when (I believe) the driver is loaded, or the OS has recognized the
interface. This also happens on my ibook.
On Linux (Suse9.3 x86_64, and Demudi 1.2.1) the noise never stops. It
just seems to diminish after a while. I haven't noticed it before I
think before I always wear headphones when I decide to work with this
interface.
Do you have any clue?

p.s. I am trying Demudi these days, but I can't achieve the same latency
I get with the suse9.3 x86_64 kernel with just the realtime-lsm module.
Jack doesn't even start at -n64 -p4 as it does on suse. Am I missing
something?

I have the same interface and I also hear the "hiss" though for me it's
more of a "capacitor hum". I've only ever used it with linux so I
can't
say if it goes away on any other OS. The sound does become quite after
a while (perhaps when the components warm). IIRC I've heard of the same
experience from other UA-25 owners, sorry I can't be of more help. It's
a pretty easy unit to take apart, if you're very curious you might be
able to track down exactly what part is humming and contact the edirol
for information.

Yes.I can hear the same kind of hum you can get when a transformer
starts resonating.
What is strange is that it stops on windows and on mac, like if the
linux driver is missing some setting.
