I'm trying to help a friend with a weird audio issue.

Initially he had his sources (TiVo and Apple TV) going to his AVR. Then one HDMI cable to his TV. Everything was fine until the TV died. So the new TV, a Samsung "smart" TV, has all the usual apps. When he ran an app (Netflix, Apple TV, Disney+) on the TV there was either no sound or he had to enable the TV's built-in speakers.

So he ran the source (only a TiVo now) directly to the TV. And ran a toslink audio cable from the TV to the AVR. The problem is that sometimes the AVR is indicating Dolby Digital, sometimes it is indicating Stereo. He says the Apple TV and Netflix app indicate Dolby Digital, the TiVo and Disney+ app indicate Stereo.

The TiVo is set to Dolby Digital. But he can hear the PCM "bongs" when using the TiVo. And he's checked the settings in Disney+ and doesn't see anything related to audio. I believe he's also checked the TV's audio settings.

Any idea why some of the TV's apps trigger Dolby Digital on the AVR and some trigger Stereo?

The most proper way to hook all that up would be to use the ARC (Audio Return Channel) port from the TV to the Yamaha ARC to get the TV Audio and still have the TiVo connected how it was.

I'm pretty sure he is using ARC. I'll double check.

And I asked him to check that the TV's firmware is up to date. The google found some posts about a firmware update fixing audio problems on Samsung TVs.

To wrap this up, the fix was a simple setting in the TV's audio section. The friend had overlooked this when doing his own trouble-shooting.

I have a newer Samsung TV and learning those settings is a must. Especially HDR and the options in audio regarding pcm or bitstream.
