My phone is interrupting my PC audio connected to Bose QC35
So I have both my PC (running Windows 10 Pro) and Phone (Google Pxel 2 XL running Android 9.0) connected to my Bose QC35 (first gen) and recently I've been having issues with my audio:
I would normally be watching a show on my PC but when I receive a notification on my phone, the audio from PC gets muted and the audio transfers to the phone. This is not the functionality of the headphones as far as I can tell. And it wasn't happening like this before. From the guide posted by Bose, to switch audio the audio needs to be paused from one device first and then payed on the other device, but this is not what is happening with me.
I've tried clearing my paired devices and did the restart method as well to no avail.
