I have Acer VN7-591G that runs win 8. I have a problem with audio. Whenever I navigate into some options related to mic, my audio almost mutes. I noticed that Dolby Digital Plus just turns off. If I turn it on manually -- everything becomes fine.
So to reproduce this problem I can do several things: go to Skype->Audio settings or open Recording Devices with right click on my mixer, or go to any application's settings with microphone (like in any online game), or start a call via Skype with anyone.
Also that happens with multiple applications: I can start Spotify after KMPlayer is already playing something and one of sources will be almost muted.
I assume that I don't have Cortana, so that solution doesn't work for me.
Did anyone have/fix this problem?
