Fixed it seems.
I has Rx sound card too, previously uninstalling audio driver fixed crashing.
Either EA updated, or I turned off Core Isolation, and it worked it seems as I am playing right now.
Thank you for posting! I thought either my sound card died or my mobo/PSU was starting to go. I have a X-fi Titanium HD and about a week and a half ago when the anti-cheat got updated, my audio started completely cutting out a few minutes into a game, but I didn't make that connection. All other audio devices work, but I have to reboot the PC to get the X-fi card to work again. I tried another card, same issue. Updated bios, updated chipset drivers, unplugged USB devices, etc. At first I was grieving that maybe my HD had bit the dust until I tried another Sound Blaster card that behaved the exact same. Then I was wide eyed thinking it may be my PSU going or worse...my motherboard (was thinking maybe the card was losing power). But like you, I tried BF4 and it was perfectly fine. But BF1 and BFV with the new update...audio dropout. So, it does appear to be an issue with the new EA anticheat update. I was going out of my mind. Still sucks, but at least now we seem to know the culprit.
