Did you notice the issue happening with only the Headphone device or does it also occur with other audio device interfaces for example HDMI, I2S, USB?
Here is a command you can use to see which part of MPD is banging the CPU.
Code:ps H -q `pidof -s mpd` -o 'pid,tid,cls,rtprio,comm,pcpu'
# Also in a watch context
watch "ps H -q `pidof -s mpd` -o 'pid,tid,cls,rtprio,comm,pcpu'"
Hi Tim,
regarding the first question:
- Yes, I have tried several I2S HATs and they all give the same results. If you want I can try HDMI (using a monitor) but, unfortunately, I don't have any devices to connect via USB.
Regarding the commands to use:
- they are the same.
Thank you and regards,
Francesco
