Thank you Sean for responding to the question, it seems I was not the
only one with this issue. I got one more following question, which usb
headset and usb audio adapters can I buy right now that are not effected
by this issue? Or should I just wait until the upcoming releases that
will hopefully fix the problem for all usb audio devices, or is this
false hope?

Best regards,
