My Yamaha receiver has been working flawlessly for years, but recently it doesn't want to recognize Dolby Digital audio any more. DTS works fine, but if I play a DVD and select Dolby Digital it uses PCM mode. Hopefully it's something simple I've overlooked, but I've already been through the manual and tried all the menu options. Also tried switching back and forth between coax and optical audio cables with no luck. The DVD I'm testing with plays in Dolby Digital mode just fine on my other home receivers (both Yamaha and Sony). Thanks in advance for any advice! Audiofan
Hi Whitesox, thanks for the suggestions! I finally got to the bottom of the problem, and it turned out to be the new Toshiba DVD player I recently purchased (model SD5000). I never had to make any adjustments to a DVD player before to make it play dolby digital signals, but this new Toshiba essentially comes with Dolby Digital diabled as its default setting. You have to go into its setup menu and switch it's digital audio mode from PCM to Bitstream. What's strange is that even with the default settings on the Toshiba it would play in DTS mode correctly.

If it is a new DVD that may be a problem, as signal changes may be frustrating this old machine... but it is likely the cabling from the DVD player to the reciever. Are you on the right channels/settings? is the optical cable and digital cable recieving digital output from your DVD player? Try changing those settings and you should be in good shape Thanks! good luck!
