Hello,
Audio stack in Raspberry Pi OS is handled by PipeWire and WirePlumber. Once the routing is configured, WirePlumber is responsible for restoring it after a restart and applying the last used volume levels.
hudiy_equalizer_sink and echo_cancel sink are PipeWire modules that are loaded from $HOME/.hudiy/share/hudiy_startup.sh
You can try setting master directly as your DAC and see if WirePlumber will be able to restore the routing after a restart. Please modify the hudiy_startup.sh as below and check what is the behavior
Code: Select all
#!/bin/bash
EC_SINK="echo_cancel_sink"
EC_SOURCE="echo_cancel_source"
EQ_SINK="hudiy_equalizer_sink"
sink_exists() { pactl list short sinks 2>/dev/null | awk '{print $2}' | grep -Fxq "$1"; }
until pactl info >/dev/null 2>&1; do sleep 0.1; done
# Gives PipeWire and WirePlumber additional time to detect all audio devices
sleep 1

You can also check the PipeWire and WirePlumber GitLab pages to see if similar issues with your DAC have been reported:
