the mellow tigger's musings

I don't know that it's related to your particular issues, but in general I strongly recommend that all live audio connections be wired and never wireless. Not wireless for headset-to-computer, and not wireless for computer-to-internet. Always stay wired. As far as I know, they never solved the wifi half-duplex problem, so no matter how quickly your devices are switching between transmitting and listening... they're still doing only one of them at a time. Wired connections can do both at the same time, resulting in smoother audio each direction. Wireless connections, on the other hand, have a "screaming" broadcast antenna that has to keep itself silent while the receiving antenna switches on to actively gather meaningful signals to process, so they take turns operating.
