All good apart from no audio output and the error message below.
Quote:Failed to open "RME" (alsa); Error opening ALSA device "hw:0,0"; snd_pcm_hw_params_set_access() failed: Invalid argument
This RME AIO works on this device using ubuntu server and aplay or arecord so not a card issue.
I will ssh and attempt to debug but meanwhile any thoughts will be mightily appreciated :-)
Oh dear..."No user account detected. Password reset function is disabled." so I can't login over ssh.. this is odd.
Ok fixed that and see now that the best way forward is to set-up a full install then save it as an iso image then use mkusb to create the portable version.
However, I am abandoning this as even a full install fails to access the RME card. It is seen and reported and can be chosen but nothing is output so assuming there are no kernel modules for it .
Daphile works OOtB for the RME card so assume the kernel is compiled with support for it.
Ubuntu server works using aplay and arecord so perhaps at a lower level than the Snakeoil interface.
