When the Dac receives no input it appears to power down resulting in earth hum through the speakers. This noise also appears approx 5 seconds after a track is paused. The noise instantly cuts out when a track is played.
Having read the below thread i believe that this is caused by the power save feature of the dac chip. I would like to inhibit this power saving behavior. I note that a patch has been posted in the aforementioned thread but I am unsure if it has been implemented in Hifiberryos or how to enable the feature.
Please could someone advise? Is there a dev kernel I can install perhaps?
I am running the latest version of Hifiberryos
