Sony BDP-S1 Blu ray player


Just purchased a preowned Sony BDP S1 Blu ray player as a back up spare unit. It's about 7 years old but works flawlessly except for the digital audio out circuit. No matter what I do or what settings I select in the setup, it simply will not put out a signal. Anyone have any ideas what I'm missing here? My AVR is a Rotel RSX-1057. I did order a firmware upgrade DVD from Sony which should be here in about a week thinking maybe it's a compatibility problem with Dolby Digital, DTS, etc. But I really think the circuit is not on. I did have an online chat with a Sony tech but to no avail. Thanks.

Thanks. I actually tried that first a number of times and do have a DVD burner but it just simply wouldn't work on two different PCs. I can't explain it but I did try that first. It wouldn't recognize the drive of my DVD writer drive when it was ready to copy. This entire experience was a total waste of time. But thanks for the recommendation.
I remember having an issue burning one the first time I tried also. I can't promise I can get it again either, but I'll try. If you shoot me your mailing address, I'll see if I can get one, and send it out to you. If not, I'm a Sony dealer, so, maybe I can get our rep to send me one.
