Hi Sonos users,

I used to have Play 3 surrounds along with a Beam gen 1 + sub gen 1. I’ve now replaced the play 3’s with era 100 surrounds. 

I noticed the surrounds didn’t sound as good with the Era 100’s as they did with the Play 3’s. 

After a bit of reading, I learnt that I should change the digital audio out format on my tv from stereo (uncompressed) to Multichannel (bypass). My TV is a Phillips. 

This has improved the surround quality from the era 100’s when I’m watching normal channels. 

However, now when I want to watch Amazon Prime Video, the speakers don’t work unless I change the settings back to stereo (uncompressed). 

I didn’t have to do this with the Play 3’s. 

Has anyone else experienced this and does anyone know why my new set up requires this settings change?

Thanks

What is showing on the Sonos now-playing screen for audio format when you play the different sources?

When the tv is set to stereo uncompressed the app says Stereo PCM. When the tv is set to multichannel bypass, the app says unsupported audio.

That should be enough for the folks that understand the TV stuff to suggest something if this doesn't help.
