How to fix Google Assistant confirmation beep
This one had me puzzled for a while as my Google Assistant would only vibrate when I said Ok Google, but all you need to do is enable a service to get it working. I didn't have any services installed but Nova Launcher counts as one so I went and downloaded that.
I couldn't show the beep working as the phone doesn't let you record system sounds at the same time as the voice over. You'll just have to trust me that it works 😉
