I started getting intermittent audio on TV 1 a few days ago, and fixed it by putting shift on for a few seconds, and then playing the shift --perfect (but rather annoying when you keep forgetting you put it on shift, and only discover the next day...). However, the firmware updated this evening, and it now seems to be fine. Fingers crossed. This, BTW, was the first problem I had with the T2200 over 2 years. I'm very happy with it.
