My mic drops out after a few minutes of using TS. I can still hear through the headset, but its like the recording part has frozen. Only way to get it working again is to restart the mic. Then it happens all over again ... really doing my head in! Never used to be a problem with old non-USB headset - but just got a new USB headset. Is there any way I can stop it happening? Is it a TS issue or something I need to do? Thanks
