I am using the latest Volumio version 3.198 running on an Allo USBridge Signature plus DigiOne Signature (spidif output on RCA and BNC) streamer. I recently suscribed to Volumio Premium for 59.99€/year to get Quobuz integration within the app which was expected to work with no issues. The Volumio app runs on iPhone and iPad (both devices running iOS 15.3), it is easy and nice to use, however the bitrates shown on Qobuz tracks are mostly wrong, and there are several usability glitches too, but the WORST ISSUE is the annoying noise or distorted sound coming out of my DAC (Hugo TT2 with M-Scaler) when going from the current track to a track that has a different bit rate, no matter if higher or lower, no matter if on a playlist or not. This happens both using USB or spidif. The issue is well reported in the forum with no solution support. This issue does not occur when using Qobuz native app running on the same iOS devices connected over USB to the same DAC. For me this is a show stopper till Volumio resolves the issue, quite frustrating, especially when I suscribed expecting a better experience...
