No. I found a thread in the Line 6 forum where some peoples encountered the problem with a variety of USB audio interfaces and some other people who tried a variety of computer and Window version. Unfortunatelly, I can't find this thread (nor other references) again, it was in the old line6 forum. no, it's something that me and other people encountered. I don't think it's a buses/chipset problem because it happen only with win 7 & 8. Some people solve the problem by installing a win XP in dual boot. (but win XP may not compatible with recent computer)

I firstly encountered this issue with my pod studio. If you search something like "ux2 sounds stop" or "ux2 stop randomly working" you will probably find some thread about in the old line 6 forum. With some people, the problems start after uptating to win 7 : no problem before win 7, sound randomly stop working after win 7. I personnaly experienced this with ux2 : compaq cq61 SF (laptop with win vista basic) : random artifact (short gap) in pod farm/ASIO with wifi enabled but work well with wifi disabled compaq cq61 SF (same laptop upgraded win 7 pro) : same as before plus sound randomly stop working, but only 1 or 2 times per month hp sleekbook (laptop with win 8) : random sound cut in pod farm, some artifact (sound like corrupted mp3) with VLC/Winamp/..., and randomly stop working, generally after 1 or 2 hours.

Yes it's very familiar for me, and this is NOT the USB Drop-out. This is a bug from microsoft. The problem exist since win 7 and happen with wide range of audio-USB hardware and computer. To be sure, next time the sound stops, just try to play/record something with an ASIO software. If it works, it will confirm the microsfoft bug. I know few solution/workaround : Use a PCi/USB card : I didn't test (i use a laptop), seems to solve problems but produce sometimes other issue :-s . It's seems also solve some "crack and pops" issue. Use ASIO mode only - It work but it's (very) restrictive : In the windows mixer, disable the POD X3 for playing and recording. You will be unable to use the pod X3 in DirectX mode (for example, you will be unable to use audacity) When you want to record something, just use an ASIO sofware (reaper, cubase, ableton live ...) When you want to jam with youtube, guitar Pro, winamp ... just branch the phone output of you computer in the CD/mp3 input of the pod.
