I have installed Android M on my Nexus Player. Love this box. It plays cable great through HD Homerun Prime. Plex works great.
I have a problem now that once I turn off my TV, when I turn it back on, the player isn't recognized and I have to do a hard restart. Any ideas of a fix?
Sounds unstable but the folks at XDA developers might be able to help you out.
This happens to mine running 5.1.1 sometimes too. Mine is connected to a surround sound system then that goes to the TV. Sometimes when I turn everything on, it's just a blue screen and the HDMI light doesn't come on on the amp. If I press some buttons on the nexus remote, then turn the amp and TV off for 10 seconds and back on, it usually works.
That's a common issue with some HDMI receivers - happens the same with my Onkyo. It's annoying as hell and as far as I know it's an Intel driver issue (adb log gets spammed with VSync couldn't be locked).
Turning on/off the receiver sometimes helps. Replugging HDMI always helps. Downgrading down to 5.0 (the issue started appearing in 5.1) always helps.
Of course Google obviously doesn't give a damn about fixing it.
Do you mean if the tv is fully off or in standby?
Is M stable enough, and did you test the new features that come with it?
