I have a big problem with some piece of my setup.
Currently I have a
Laptop > M-Audio Transit > Glass toslink > TriVista 21 DAC.
Problem: I sometimes get a loud electronic buzz.
I am playing music through the computer I am doing work on, but I still wouldn't expect this.
I have had my headphones on here when it happened 2 of the 3 times. I've been using the setup only this week.
1) I switched windows (gave another window focus in Windows) and got the loud buzz for about .5 sec.
2) I dropped a folder of music into Foobar and got the buzz for about .5 sec.
3) I left my desk. When I got back my cans were emitting the scary buzz. My neighbor here at work said it lasted at most 2 minutess, but she didn't want to mess with my gear. I immediately unplugged the transit's usb cord from my laptop. Sound stopped.
I know it's triggered by windows, not the DAC, and not the Transit... though I think the Transit has some responsibility.
I have not heard the buzz through the line out of the Transit, but the buzz has happened only once per day at most, and I have not tried the lineout long enough to catch it, if it would happen through the line out.
SO
Windows is clearly triggering it, but what is specifically happening?
Is windows actually sending bad data to the Transit?
Is the Transit responding to power fluctuations in my computer by sending the noise across the toslink?
Might some piece of my chain be haunted?
I think it may be the same buzz I get through a line-out of a stock soundcard... but from the card it's very faint, whereas through the DAC and amp it is very disproportionately loud. (You've heard electronic noise through your stock sound card, right?) Besides that, I wouldn't expect the Transit to transmit that noise as sound.
I also sometimes hear a big click when I open an audio program. I sometimes get it when I double-click to another track in foobar's playlist. When I fire up another player (VUPlayer) it doesn't do it anymore.
Have any of you experienced this? If so, how'd you resolve it? If not, I envy you!
(I just turned latency from Medium to Very High.. maybe this will help... any ideas?)
