Pro - Multiroom Highe Res Audio with Amazon?

[Witterings]

I know the Mini's weren't able to play high res mutiroom music using Amazon Music Unlimited but am I right in thinking this was resolved with the Pros, in other words if you're playing a 24/192 track multiroom to 2 or more Pros, will they both play at 24/192 or does it get scaled back / reduced to say CD quality?

I'm pretty sure alll wiim groups are 48khz max.

On my device, when the Pro is the master device, it is HD. Other combinations give strange results.

Ultra + Pro =24bit/48kHz
Ultra + Amp Pro =24/48
Ultra + Amp =24/48
Amp pro + Pro =24/48
Amp pro + Ultra =24/48

Amp + Pro =16/44.1
Pro + Ultra =16/44.1
Amp + Ultra =16/44.1

At least in my case only the combination of Ultra and Amp Pro can play 24/48 on both sides. (Note that the rate indication shown in WHA is error prone, so be careful).

I think Amazon MRM groups themselves don’t support more than 24/48 from tests I’ve done before. There’s no point in asking Amazon to confirm that as their agents wouldn’t understand the question…

Edit: note that 24/48 conveniently ticks the UHD box…

Those are strange results - it does lean towards the Ultra and the Amp Pro behaving differently when masters in an Alexa MRM group.

Edit: although I guess you’re grouping in the WiiM app as you talk of a master device which you can’t choose in Alexa. I wonder what results you get if you group in the Alexa app?

Yes, I haven't tried the Alexa group yet.

I have to install a dishwasher in my kitchen today! Thus, I may test it later.

Btw Amp pro sometimes gave me this error and I had to play other tracks (or playlists) several times before returning to the test track.
