I have a used S40 prooved by a reliable dealer, therefore I can assume that it is not a hardware problem.
After some time of rest - Roon is still running on the notebook - the CPU load increases and I have problems with the selection of albums and long dropouts during playback.
If I restart the S20, the CPU load is ok, but I have problems with playback. I have now restarted twice because of this. The first time Squeeze was not found by Roon. I then switched to Roon Ready as the player.
On the next restart due to CPU load, no sound was output, still with Roon Ready as player. I then switched back to Squeeze and activated Squeeze in Roon. After that I heard something again.
Firstly I have the impression that there are problems with the Antipodes config and the new Roon version and then I am afraid that Roon implements background processes in new versions that the computer in the S40 will not be able to cope with in the long term.
