AudioOut_2 Wakelock Drain (4.3)
I've recently been experiencing some massive battery drain from a system wakelock called audioout_2 (or 1013 in wakelock detector). I've tried searching online and found a few posts saying it's related to Viber or some audio app. Problem is, I don't have Viber installed and it doesn't appear after using any specific apps. I haven't installed anything new recently that could account for it (at least none that I can think of). It's been appearing randomly since I updated to 4.3. I've checked background processes and can't figure out what it could be. I've also tried Greenifying many apps or freezing them with TiB to no avail. Last check said my phone was awake 90% of the time.
If someone could please provide further insight or any suggestions, I'd appreciate any help. Thanks a lot.
I'm on a rooted Verizon Galaxy S3 running various Xposed modules.
