Hi, I've got this problem with my intex USB Audio Speakers where whenever I plug them in my Windows 7 powered laptop, they just don't work. The default audio device in Control Panel/Sounds changes automatically from my onboard High Definition Audio Device to USB Audio Device (which I think it's normal). Also, there is no problem shown in Device Manager and when I hover my mouse on the Sound icon near the clock (system tray or notification area) it shows that the USB Audio Device are the default. I contacted Intex and they first told me that it might be a laptop problem, but then I installed Windows XP - the sound works great. I installed Ubuntu - the speakers are working also. It seems like it's a problem in Windows 7. I sent them another message telling them this, but they have never contacted me again. Please help! I would love to be able to use these speakers since their sound is so much better!
