I am new to Manjaro linux and i am encountering a strange issue:
I am using DAC trough optical and if no sound is playing on my computer it does not send a keep alive signal and the DAC will turn off after a period of time.
In order to stop this i edited the /sys/module/snd_hda_intel/parameters/power_save profile and set the default value to 0.
This works and my DAC will no longer turn off if after a period of time with no sound playing on the computer.
However after reboot or power-off the setting in that file returns to its default value of 10 and this will get the DAC to turn off if no sound is playing for 2 mins.
How do i get that setting to persist ?
