When listening to music at night the Raspberry Pi power LED is blindingly bright. With RuneAudio I was able to use the method below to disable the power LED. It works beautifully.
raspberrypi.org/forums/view … 66#p136266
With Volumio, those LED brightness control paths don’t exist. I was able to find the “ACT” LED brightness control at a different path (see below) but cannot find the brightness control for the power LED. Any advice?
/sys/devices/soc/soc:leds/leds/ACT/brightness
Try this:
Search for files named brightness with:
find / -path /mnt -prune -o -name ‘brightness’ -print
The mnt folder is skipped to speed up the search.
On my raspberry pi two files are found:
/sys/devices/platform/soc/soc:leds/leds/led0/brightness
/sys/devices/platform/soc/soc:leds/leds/led1/brightness
To turn the power led off:
echo 0 > /sys/devices/platform/soc/soc:leds/leds/led1/brightness
To turn it on enter any number larger than 0.
Thanks for the suggestion, no such luck w/ my raspberry pi 2. Just the one LED device found and this controls the green activity LED.
