I got m Tascam US-122 it works fine, the mixers for it dont work in
Qamix and gnomealsamixer, when I choose the usx2y soundcard the mixers
are blank, nothing there. IS that suppost to happen?
ANyways, I am getting noise from my KRK Rokit powered 5 speakers,
headphones in the tascam gives me no noise, then I plug from the
headphones output of the tascam to the speakers and I get noise! So I
think it might have something to do with the speakers?
The noise starts when I plug the USB for the tascam in, even when its
not plugged in and just touches the metal it makes the noise.
When I unplug my AC for my laptop, the noise stops... WHen add
brightness to my laptop screen I get less noise...
I suppose your laptop has an earth connection on the power cord. Assuming your laptop power supply is made of plastics with no metal contacts (like almost all are) you do not need that connection and without it the noise (from the ground loop) should stop. Just put some kind of isolating tape over the metal contacts from the earth ground (maybe two layers, because it might get cut when plugging in) and your ready to go. If you don't want to carry that tape with you all the time you should try to exchange your power cord (those from electric shavers looking like an "8" work sometimes).
Good luck!
Does anyone have any solutions, more troubleshooting tips? Thanks.
