This is the speaker I have
Jam Alloy™ Wireless Stereo Speaker | Jam Audio
Normally, I use a head set with a microphone and headphones, but I have this (actually was a christmas present) in case I needed to play sound for someone else to hear for some reason.
It is primarily a bluetooth device and I'm not even sure if my computer is bluetooth compatible (where would the bluetooth hardware be located if it is? On the motherboard?) but I'm trying to set it up in windows 7.
When I plug it in via USB, it doesn't react at all, as if I never plugged it in. I have a device listed as "OTG 102" under Control Panel/Hardware and Sound/Devices and Printers, I'm not sure that it.
However when I plug it in via the audio jack, I do get a response. Real Tech HD audio manager appears, but I don't know what kind of speaker it is (it asks me what kind, a few different kinds of speaker- front speaker out,rear speaker out, center subwoofer speaker out, etc. I don't know what these mean)
The company says they don't make drivers for the device and their technician I talked to one the phone was not well trained and didn't know how to make it work in windows 7.
