Windows 10: Can't hear voice chat and video calls and people can't hear me

my pc specs

• Windows 10 pro 64 bit w/update KB4023057
• Intel Core i7-3770K
• 32gb DDR3 RAM
• GeForce gtx 970
• Asus Z77 sabertooth

So when I go to sound under Control panel everything shows up fine in playback and both microphones show up (my headset and webcam) and even when I enable playback I can hear myself just fine so I know its not hardware. But whenever i enter a chat like in skype, teamspeak, discord, or any game, Ican't hear anything and people can't hear me. I've double checked and i have the most current drivers and I have also re-installed the drivers from scratch with no change. i've had this issue for a few months and now my job heavily relies on skype so i need this fixed.

Can't hear other programs' sound when using Bluetooth headsets with voice chat applications on Windows 10

This happens on both my Windows 10 systems, a late 2012 iMac and a custom-built PC using an ASRock Z170 motherboard and an Insignia Bluetooth dongle.

When using either Discord or Mumble and either Apple AirPods or a Bose QuietComfort 35 headset, I cannot hear sound from any other application unless I set the output device to the "Hands-Free Device" instead of the "Stereo Headphones" device.

The problem with that is the "Hands-Free Device" has only one sound quality option, 8 KHz, which is nowhere near the 44.1 KHz default of the "Stereo Headphones" output device. When I select the "Stereo Headphones" device the sound is great, until I open either of the mentioned voice chat applications, whereupon I can't hear anything until I close that program. Also, my mic does not work unless I re-set the communications device or default device to the hands-free option. If I set the hands-free device as the communications device, everything in the voice chat app works, but no other program has any sound.

I believe this is because the "Hands-Free" and "Stereo Headphones" devices are two separate Bluetooth services, and the Hands-Free device is activated whenever the voice chat is engaged, and remains that way until the "call" is over. I realize the "Communications" tab in the sound control panel is supposed to fix this sort of thing, but it changes nothing in this scenario.

Any ideas?

EDIT: I've read the suggestions in this post, which I just discovered, and none of that works:

• Removing the Hands-Free Telephony service removes the mic.
  
• Changing the "Exclusive Mode" setting on any playback or recording device does not resolve the problem. Sometimes it does temporarily, then it reverts back to the problem described above within 5 minutes or so.
  
• Disabling audio enhancements does nothing.
