Hi all,
I have a new computer which I have configured by just "transplanting" the old HD into the new hardware. Almost everything is working as intended, except for the SPDIF output, which works until it doesn't anymore. The old hardware worked flawlessly.
For context, my computer is on 24h/day. When I reboot the machine, everything works flawlessly. Then, after ~3 days of uptime the SPDIF output will go rogue: everything appears to work, the PA control graphically shows sound being played through the output, etc., just nothing comes out. Rebooting the computer makes it work for a new cycle.
I am assuming this has something to do with the sound card driver, which enables some kind of energy saving mode from which it is incapable of recovering. In fact, each time sound starts playing it takes a couple of seconds to come out, as if the card had been turned off and needed to restart again.
This is the card info from pactl list cards:
