Hi list, I turned on my laptop this evening and plugged in my Bose Soundlink dongle which is basically a USB headset. Normally my default speakers cut out and the USB headset takes over. However this evening my speakers don't cut out and the headset doesn't come on either. I get the tones which would indicate that the device has engaged but no joy as far as sound is concerned. Please can anyone tell me what the problem might be and how I can fix it? Is it possible that a windows update has screwed my settings somehow? How can I check that it's not my USB ports? Sorry for all the questions but I really would like to get this sorted. Thanks to anyone who can help, Andrew
