i have companion 5 5.1 bose speakers on my compter. i've looked this up on google i've asked the company itself nothing is working. basicly i've had these speakers for a few years now, i used them with two vistas 32 and 64 bit and now a windows 7 64 bit. the speakers never gave me trouble on my vista computers, but this win 7 they don't seem to like. basicly it's gone from the speakers choosing when the want to work to being plugged in and not even showing on the volume control devices, i don't even get an icon. if it helps the speakers are usb only, there is no jack for any other sound output or input. when i asked bose at first they said basicly i was making this up, then i asked again and they said to reset the speakers by unplugging them. so i've been doing that and it's been working up untill now. when i reset the speakers my computer makes a beep like it does when a device is unplugged and beeps again when i plug the bose back in. by the way i have two sets of speakers my beloved bose and the crappy things on my moniter. so i know the computer knows they are plugged in but no device shows. and if you can give a fix that don't have to pay for, i'm broke i just bought a new backup battery, 3 puff trucks, and gran turismo 5 which were basicly 210 bucks together [i got the trucks 50% off]. i'm assuming i'm broke i don't have the info for the family bank account online.
