some little problems on my Kodi

Hello everybody, I’m new here.

I need help about 2 things.

I’ve installed raspbian pixel on PI3. I run MPD and KODI.

First, kodi doesn’t reconize my DAC each time, especially when I play music with mpd. Can I force KODI stay on my DAC. I remove pulse audo, it works randomly now…

Second, screensaver runs for 5sec, like if something wake up kodi every 5sec. I searched everywhere in the settings and nothing… May be the update of the library by defaultConfused

Otherwise Kodi 17 is beautiful and smooth

If somebody has a idea
