Hi guys, So I have had this lingering problem that doesn't happen very often but when it does its super annoying! Here is my "system".. 1.) ibm t60 laptop with Windows 7 32-bit. Using Itunes 10 for music playback 2.) "Hot Audio" USB WoW DAC 3.) Sony STR-7055 4.) KLH model 6 So i would say about 95% of the time everything plays smoothly from my computer and I'm happy. What happens occassionally, however, is that I lose the left channel and beautiful music gets replaced with static/crackling sounds from that speaker. I used to think it was my receiver (was using a yamaha) but I have since replaced it with a known working Sony that sounds excellent. I've read of others having these kind of issues with USB DAC's so that's why I believe its the Dac. While this only happens occasionally, i would like a completely working set up without worrying about this happening at all.. Any ideas, please?
