Yesterday, I installed the EA version on my HIFI Rose RS-150B. I also downloaded the early access version on my phone. Everything was as usual, but I couldn’t play music on Tidal, Qobuz, or from my interal USB Storage.
I noticed that the relay, which switches the XLR pre-output, simply didn’t engage (it didn’t click when switching). I think that’s why I couldn’t play any tracks. I just saw a spinning circle around the play symbol.
I had to roll back to the official version. But even that wasn’t straightforward. I had to do it twice because the operating system kept loading with errors, and I kept getting a pop-up window asking me to restart the device. Then I had to do a “Factory Reset” again, and only after that did everything start working fine.
