I have a Holo red and Cyan 2 and I have the same issue. Plays for about 25 minutes then stops. Then I have to restart host and target via Gentooplayer. If I were not do the noticeable sound improvement, I would give-up and pass on Diretta. I have a rasbPI 5 as my host. Im using Gentooplayer and Roon, no Hqplayer
