Hi, I have a Sinotec (Skyworth) AndroidTV which pretty much has similar CPU and other specs to some of the Sony Android TVs. 2018 model with Android 7 and Google assistant.
Anyway, I had my audio hooked up to a logitech bluetooth adapter and its been running fine for the passed 5 months. I noticed an update today and after the update, my volume slider for bluetooth now shows the actual volume as well, but it does not actually do anything.. I can change it from 100 all the way down to 1, no change. If I put it to 0, it mutes the audio. Muting works fine. I tried connecting my Bluetooth earphones, same issue. I factory reset as I thought maybe the BT was just messing around. Same problem.
This sucks, now I have to literally get up and go change the volume on my speakers connected to the Logitech BT adapter.
Any fixes? I may just end up taking this TV back to the store and asking for a replacement that I will not update.
Oreo for Android TV is garbage. My volume control for headphone output is broken too. And cannot control optical audio volume at all. Only way to use audio properly is using integrated speakers or really expensive HDMI ARC audio system (receiver) that costs half or more the TV price.
