I have run into a problem with trying to use PC speakers on a headless server running bookworm with all the current updates. The hardware consists of a Gigabyte Z790 motherboard sound card. The problem is a 60 cycle hum, but it is not the result of your conventional ground-loop scenario. When the sound card is active there is no hum, even during the few seconds of quiet before and after a music file plays. The hum is only present when there is no activity. It appears the sound card “floats” when it is not actively being used and picks up the hum.
Now for the question. All I need is for speaker-test to run as root with no hum between runs and with no users logged in. I have tried a lot of things and what appears to be the simplest thing to do is to install alsa-utils and alsa-oss. It meets the criteria of running as root with no users, including root, logged in and would be perfect except for the hum. If I run Windows on the same motherboard, there is no hum between uses, so I suspect if I could keep the sound card active all the time (daemon??) while still being available to use speaker-test when needed, life would be good.
Any suggestions?
