It sounds like your 861 has a problem.

It may ultimately be a firmware fix but doubtful since no other reports of this type.

Not that this is final solution Try setting poor digital source on any source that has problems.

One other thought is a ground loop can cause odd issues like this. On a digital link if it's bad it can cause a drop out (instead hum). So try applying normal ground loop solutions (first being try disconnecting DirectTV from the system). In fact try disconnecting everything and try one source at time.

It's long shot but worth checking.

If you think listening to music is fun, try learning an instrument.
