I have this random problem where all of a sudden, sounds starts being muffled. I wonder if it is related to the sound lag problem I had due to using too high graphic settings?

Cpu: Amd A8 7650 (yeah, I need to upgrade it)

Gpu: Rx 580 8gb

Ram: 2x8 gb ddr3 1333mhz

I have this too. Voices sound muffled or distant, even when they NPC in question is right in front of me. Music and sound effects sound normal. Oddly enough, speaking to ADA sounds normal as well.

probably has to do with the directional audio. Change sound setup ?. Stereo should even everything out. I haven't even looked at the audio options, but i play with surround speakers and the voices do sound a little meek compared to the effects. 

Thanks! Tried adjusting different sound settings on Windows, they don't help. Altered various levels in the Audio menu, still not sounding right.

While testing it, I found something else odd with it. Talked with Jane Elson (first NPC you meet when docking with the Groundbreaker), and she was muffled when I looked at her while speaking. If I turned away while she's speaking, it sounds normal/correct. If I'm turned 180 degrees away from her, it goes back to being muffled. Again, music and sound effects sound normal, only voices are affected.
