Thank you for the attention. I think the issue may be in the last Ropiee update for the Allo USBsig. I tried signing out of Qobuz in Roon and then back in and that did not help. It turns out that it is not only Hires Qobuz tracks that do not emit sound. No tracks, local or Qobuz stream, are emitting sound through Roon on M1 Mac mini via ethernet to Ropiee/Allo USB sig/Qutest dac without using sample rate conversion in Roon.
However, If I insert HQplayer into the chain I can play 16/44 files without sample rate conversion in Roon but no Hires files. If I try sample rate conversion in Roon then HQplayer does not play any sound. I can play all tracks through the built in mac mini speakers using Roon without having sample rate conversion enabled, but downconversion is being performed for the hires tracks above 96 kHz as expected. This makes me think the issue is with Ropiee.
All of the tracks appear like they are playing in all of the scenarios with normal time passage in both Roon and, when activated, through HQplayer. It even shows the sample rate conversion being performed in HQplayer and the correct signal pathways in Roon under all the scenarios.
I have a new Rpi4 coming in tomorrow and will try Ropiee on it. Maybe it is the unique Ropiee for Allo USBsig that has the issue. Both Roon and Ropiee did updates right before Christmas.
