Since I read about following commands to reset the DSP in (https://www.hifiberry.com/beocreate/beocreate-doc/beocreate-use-sigmastudio/)
gpio mode 0 out gpio write 0 0; sleep 1; gpio write 0 1
I wondered if it is possible to send the DSP to sleep via a script in the Raspi and then wake it up again if demanded?
You can use the reset for this. However, there is no specific "sleep" mode. Therefore, this will only save a bit of power on the DSP. Other parts of the circuit will still be running.
Is there any way to significantly reduce power consumption when unused, apart from unplugging ? And automatically wake up (wake on lan for instance) ?
