    I frequently play long playlists on my Nexus 9 tablet while it sits unused in any other way. Since updating to Marshmallow, the audio suddenly slows down to (at a guess) 50% normal speed after the tablet has been idle for 90 to 120 minutes.

    For now:

    The tablet needs to be woken up and the audio file stopped and restarted to restore normal speed.

    What I tried:

    My first thought was that Marshmallow's new energy conservation system, Doze, was likely to blame. Disabling it* for the media player makes no difference, nor does
    - skipping to the next or previous track,
    - playing tracks on the LAN or on the tablet, or
    - using half a dozen other media players. (Rocket, Jet, AIMP, SambaPlayer, Kodi and ES File Explorer's Media Player all playback audio at 50% normal speed after the device has been idle for 90 to 120 minutes.)

    As this behaviour only started after updating from Lollipop to Marshmallow, I still suspect Doze is somewhere at the root of this. That said, Google produced no obvious mention of anyone else running into this issue and it seems unlikely no one else would have bumped into this.

    The tablet is not rooted and both the original Lollipop and the current Marshmallow were auto-updated from Google.
