After leaving the machine idle for some time, no sound is audible till sound preferences is opened

[David Nielsen]

I found that if I leave my machine on while e.g. cooking dinner, when I come back to it and attempt to play some audio. No sound will be audible till I open the sound preferences.

Is there a bios update for this board?

[David Nielsen (davidnielsen-deactivatedaccount)]

Incredibly there is an update and it is even labelled Linux. There is no Changelog so far as I can see so I don't know if it addresses the issue. I've flashed the machine and will follow up once I have tried to trigger the problem.

The update appears to fix the issue

[David Nielsen (davidnielsen-deactivatedaccount)]

Closing that outdated report as EOL has been reached long time ago
