Sweex USB problem with Raspbbery Zero with v0.7

Pi MusicBox
1

After the installation Sweex USB sound card does’t work (no sound from audio). Work nicely with PC or MAC but not with Pi MusicBox on RPi Zero. Thanks for any advice or suggestion.

Does it work with Raspbian? Did you set the output setting to ‘usb’ ?

If you are can, please provide the log file at /var/log/musicbox_startup.log and the output of aplay -l.

Output setting is set to USB.

Is that with Raspian on the same Pi0?

And does it show up in lsusb - mine shows as a audio controller.

And also shows up in aplay -l This is my aplay -l, the usb audio card is at the end and is card 1, on yours it’s not showing up.
