    Thanks for looking into this. It seems to me that controlling brightness belongs in the display software like all other Operating Systems. That is probably beyond the scope of M2P but it would help for them to take the lead.

    I went back into the Brightness file and the new value was there. To save the value I changed the file attribute to R/W. The system is running Max2play 2.41 (released version). The file Actual_brightness shows the value entered.

    My setup consists of Audio Player running Squeezelite, Squeezebox Server, Jivelite, RPi-Display, HiFiBerry, Filesystem, Raspberry Settings, and Remote Control. The hardware is a Raspberry Pi model 3 and a HiFiBerry Digi+ Pro.

    I am interested in reducing the screen saver clock brightness.

    Thanks for your continued help.

    I was able to change the brightness file but it had no effect on the display. I tried 128 and 64. Is there a way to apply the change? Rebooting the Pi did nothing to the display.

    The remote control installed without incident.

    Following the instructions for changing display brightness I am getting a Permission denied error:

    With Max2Play I do not have direct access to a command line. Adding the command to Squeezelite Command Line Options caused Squeezelite to not start.

    I would also like to see a screen brightness control made available. Exposing that feature would not be difficult as it can be done through a command line argument to the official Raspberry Pi display.

    [UPDATE] Most of the music was formatted uncompressed ALAC (.m4a). Using JRiver MediaCenter I converted some of the albums to FLAC. The problem seems to be gone now but it will take some time to be sure. Anyone else experience issues with ALAC formated music?
    – Thanks

    That worked. Does USB DAC support all data rates? When I play ripped CDs (AAC or FLAC formatted) my DAC indicates a 48KHz sample rate instead of the expected 44.1KHz.
