Audio drops out entirely throughout entire PC

I have exactly that same issue and i am able to fix it by turning Spatial sound On or Off

My game also starts with audio and less than a minute in menu, no more audio. 
Scarlet audio interface, never had any issue before

bf4 runs with no problems

Having this problem too, Using Scarlet 2i2 4th gen with up to date drivers.
I saw people having a similar issue 2 years ago but seems like it's back.

Things I tried but didn't work:
-Updating drivers
-Verifying game files
-Re-installing EA anticheat
-Messing with windows spatial sound
-Changing USB ports from 2.0 to 3.2
-Disabling all other audio playback devices
-Making sure I'm using 48kHz sample rate
-Changing "allow exclusive control of this device" setting
-Changing many ingame audio settings

same here

Same here with Audi problem

I am experiencing similar issues with an EVGA Nu Audio sound card. I read several reports of owners of different Focusrite devices having these audio dropout issues as well. I found out that one thing all these devices have in common is the use of an XMOS chip as the main sound processor: 

• EVGA Nu Audio uses XMOS XU216-512-TQ128 
• Focusrite Scarlett 4i4 3rd Gen uses XMOS XU216-256-TQ128
• Focusrite Scarlett 2i4 2nd Gen uses XMOS XU208-256-TQ64

It is quite likely that EA Anticheat does not play well with these XMOS sound processors. The thing is, my sound card works well in all other situations and I assume it is the same with you Focusrite Scarlett owners. So it would be great if someone at EA could provide a fix to their Anticheat software.

i hope they fix it

I hope so, too. Would be a real shame if the next Battlefield (or any other future EA titles) would suffer from the same problem. 

having the same problem unfortunate that EA isn't responding at all

That's the fix for now
