Pioneer VSX-40 not properly decoding.
About a year ago I purchased a 5.1 theater in a box used from goodwill for like $20. It was an RCA RT2360B with the 5 speakers and sub. I have slowly been upgrading as I go along.
I found a Yamaha VSX-40 for sale and just picked it up. I had my TV (crappy best buy insignia) hooked up via optical audio cable to the RCA receiver and it played 5.1 just fine. I had my TV set to PASS THRU.
When I hook up the optical cable to the Yamaha receiver, the sound plays but its all cracked and scambled. If I change the audio setting on the TV from PASS THRU to PCM, the sound plays just fine, but then it is only 2 channel. I also don't want to hook up anything through the HDMI ports on this receiver. I only have 1 HDMI component on this TV and it is the Firestick and I like having it hooked up to the TV so I can control it with my television remote control. I did hook up the firestick to the receiver to test 5.1, but I couldn't get any sound when the video starts. When I am using the remote control to select different items on the screen, I can here a "clicking" sound that the firestick makes, but when the video starts, there is no sound. Not sure what I am doing wrong.
Is there a setting I am missing on the Yamaha receiver to make it correctly decode the Pass Thru signal from my TV? I just find it hard that this crappy RCA receiver does a better job then the more expensive Yamaha one.
Any info is appreciated. Thanks
