I'm trying to help my step dad diagnos his Yamaha RX-V1500, which appears to be having issues decoding some signals. He started noticing that when a TV show would go to commercial break, he'd lose audio or become very faint. If he switches to 7-Channel Stereo, it works fine but using a Pro Logic or Neo 6 setting it appears again. It didn't used to have this problem and seems like a decoder issue to me... I'm posting here on the off chance someone might have some advice. Are there any settings in the receiver that could be causing this?
Look at profile for Gear info.
