Before I could turn on Bluetooth after I log in to the game and it would work, now the sound disappears immediately. On the other hand, changing to 16/48 fixes the issue with the sound when it sometimes glitches. For example, 24/96 made the theme on title screen sound like Squarepusher's remix of itself, and I even thought it was intentional until I changed the parameters and found out that it's not. It still won't fix a bug with the sound disappearing entirely and only coming back after game restart, I have this one once in 4-5 hours. Or sometimes the sound becomes 2x faster or 2x slower, also only fixed by restarting. I also tried to put everything to 16/44.1 which is my headset specs, didn't work.

Hilarious! If it wasn't a bug :(
So yeah sounds like you are hitting multiple issues - the sound dropout bug is being worked on (it's actually multiple things that can cause it) - we hope to have it totally fixed in the next couple patches.
For the sample rate thing - the official word from Frostbite is that anything higher than 16/48 is not officially supported. Can you double check that ALL possible 'enhancements' are disabled and ALL output devices (speakers, onboard sound, headphones, everything) is set to 16/48? I know switching while the game is running caused total badness so I'm not surprised by that.
Also do you have wired headphones or the ability to disable USB/Bluetooth and go ol' school analog to test that?
