Volumio on Pi Zero W

Fri May 14, 2021 6:41 pm

I’m trying to get my Cambridge Audio DAC Magic Plus recognized by Volumio but even the aplay -l doesn’t lists it, neither does lsusb -t The DAC is mentioned in USB DAC Compatibility list on Volumio's site
https://community.volumio.org/t/usb-dac ... t/1997/199
volumio@volumiopizero:~$ lsusb -t
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=dwc_otg/1p, 480M
volumio@volumiopizero:~$ aplay -L
null

It seems to me that the Pi isn’t even initializing the DAC drivers. FYI, I’m using a RPi Zero W, feeding it power through Ext port of the DAC and feeding the Type B port of the DAC with Micro USB Data port.

Never mind, looks like a faulty Micro USB to Type A converter was causing the issue. Replaced it with another and rebooted the Zero and when Volumio loaded, it automatically recognized the DAC.
