piCore 5.0.alpha1
bmarkus:
Difference is that in 5.0.alpha 1 the snd_usb_audio module is not loaded which is required. Try
--- Quote ---sudo modprobe snd_usb_audio
--- End quote ---
than Alsa must work. Check modules loaded with
--- Quote ---sudo lsmod
--- End quote ---

Sorry for the delay, I broke my SD-card with version 5 on. So I had to find a spare one.

OK, now it finds the USB-DAC:
--- Code: ---tc@box:~$ sudo modprobe snd_usb_audio
tc@box:~$ sudo aplay -l

Thank you for your help.

NB: Regarding the need for sudo - and the difference in your # and mine $ promt. Is that something that you will change or is it as it should be?
bmarkus:
Glad to hear it works. The alsa-modules tcz has a startup script which modprobes the kernel module for the built-in sound device. I will add the modprobe for snd_usb_audio so it will be loaded at startup.
bmarkus:
Updated alsa modules uploaded to the repo, please update.
