[Solved] Audio works BUT no system audio . / ACPI Errors.

Recommended Posts

My audio seems to work . I can listen to music and watch videos .. my front and back ports seems to work . When I plug my headphones on the front panel they are recocnized as Headphones and the audio is great .

The issue is that System audio (OS Audio sounds) doesn't work .

Where should I begin with to troubleshoot the my whole audio thing on my system.

My audio chip :

Realtek® ALC1220-VB codec

* The back panel line out jack supports DSD audio.

High Definition Audio


Support for S/PDIF Out

Issue number 2 :

My request is .. does anyone can fix my ACPI errors . I've seen the tutorial but just can't do it . I will mess up the whole thing . If it's too much effort and you don't want to mess with mine problem I respect that .
