Tvheadend needs some load

After I’ve moved my tiny homelab server from my desk closer to my living room (who wants to run a cable through his house?), I haven’t been able to establish a stable connection anymore. I’ve got many artifacts and delayed audio all the time. It looks like tvheadend needs some cpu load to prevent continuity counter errors. Other than that, some user on the tvheadend forum found that the issue was far less if USB3 is disabled in bios to avoid using the xhci driver.

I haven’t had this problem when I was using it as a desktop. As of now I’m just running stress-ng --cpu 1 --cpu-load 100. But I’m not that happy about as temperatures and power consumption increase.
