Odroid C2 HiFi Shield, DietPi and HQP NAA

[Dan_Knight]

HQP NAA - Raspberry Pi

For me though, this is the end of the good news: the Odroid HiFi Shield 2 simply doesn’t work with HQPlayer - it gets Alsa underruns. The CPU at the time is 2-3% for one of the cores and nothing - for the others.Roon works a bit better, but the sound disappears completely after 2-3 track changes.I haven’t yet tested with a USB DAC, will report when I can.

Try increasing the buffer time (size) in HQplayer to 250ms:

Failing that, also on your Odroid C2, try setting NAA Daemon to a higher priority via realtime FIFO scheduler:
dietpi-process_tool > NAA Daemon
