Upcoming moOde 9.0.0 (Bookworm)

Ok, cool.

When convenient try the latest commit to worker.php to see if the software volume issue at startup with your USB/BT device  is resolved.

Probably tomorrow.

As for multiple DACs, I couldn't resist hot-plugging my Khadas Tone 1 USB DAC into the same Pi-4B with the Creative Tech USB-BT Adapter and the Inno-Maker I2S DAC already installed and enumerated as Card 0 and Card 3.

The newly plugged-in Tone 1 shows up as card 4, can be selected, and plays as expected. 

Reboot. 

Now the two USB DACs are enumerated as cards 0 and 1 and the Inno-Maker I2S DAC as card 4. The Tone 1 is still the selected DAC that plays when I start a track.

Pretty cool.
