(Z5 Compact / E5823) Speaker volume lowering itself

Greetings.

Just bought the Z5C. Phone is awesome, but when I play anything over the speakers (incoming call, music, etc.) the volume is good for about a second, and then it turns very silent.
Anyone experienced this, or knows something about the issue?

Nexus Player - Sling App opening itself

Has anyone experienced the following behavior:

On a couple of occasions with Netflix playing a show it will kick itself out and Sling will start to load. I don't use Sling, but I have previously opened the app to check it out. I have force closed the Sling app and it seems to have stopped this behavior, but I did find a recent reddit thread that described a similar issue and was wondering if anyone here has experienced it. Don't know if it is a hardware or software issue since I got the nexus player only a couple of weeks ago and just received the update to 6.0.
