Just when i boot the SPDIF is acting weird. First i hear something that sound like a laser-beam, i hight pitch sound turning into a low pitch noise. Like the Doppler effect. Then i hear some noise that sound like someone is blowing in a mic.

The "blowing in microphone" sound will continue until i play any sound with the computer, then everything works just as expected. Therefor, it is not a big problem during boot as i have a startupsound, but it is quite annoying after i resume from suspend.


I want to know what is not activated before i play a sound, and how to activate it.
