You can only change those audio settings while the player isn't running. Verify that you can when the player is stopped..

Do you have a computer that you can check or give someone your finder ID and have them check it?

Your SlingBox came with 2 cables, have you tried the other cable?

Hope this helps,

Slinging Tivo Series 2, Tivo HD, and TW cable from a Pro. Slinging Tivo HD from a Solo, Slinging Humax DRT800, and TW cable from a Classic to Sprint Mogul, AT&T SX66, N62, 8525, and Dell Inspiron 8600 with Sprint EVDO over Windstream DSL.

This says that it is one of the devices (cable box or SlingBox) or your cabling. Have you tried the other cable and/or are you using the RCA outs to a TV or other device to know they're good??

I have to stress that the connector to the SlingBox has to be pushed in much harder than you would expect to get the proper connection...
