Sonos System: Port output to Rotel A14 Mk 2 internal DAC/to a pair of Monitor Audio 20se speakers (living room), and a seperate pair of Monitor Audio 2se speakers (kitchen).

I’ve also a pair of Sonos Play 3s in the kitchen, and a single Play 3 in a bedroom.

The Sonos Play 3s succesfully play HD tagged music from Amazon (even though they’re the furthest away from the router).

The Port (even though it’s far closer to the router) will play HD (and even occassionally Ultra HD) for a few minutes at the most before the badge disappears. However, if I link the pair of Play 3s in the kitchen,or the single Play 3 in the bedroom,with the Port, the HD badge stays.

I suppose I could link a Play 3 (with the volume to zero) if I’m listening via the Port, but that wouldn’t work with any Ultra HD tracks.

Any suggestions would be welcome.

Amazon uses adaptive bitrate streaming on Sonos. (See https://tech-blog.sonos.com/posts/happy-music-streaming-with-mpeg-dash/). If the wireless connection to the Port is iffy the stream is likely to fall back to SD.

Sometimes a device can get ‘stuck’ in SD despite the connection being okay. Rebooting it usually fixes this.

Yep, that is a Factory Reset that wipes all data off the reset unit.

When it really hurts is when you Factory Reset your only Sonos or all of them at once and have to do all your configuration, favorites and playlists over from scratch.
