[ubuntu-studio-users] Steinberg UR22mkII

[Ross Gammon]

Hi Hans,

I am not sure why you say no input is available. I believe the
sub-devices are referring to the number of streams/channels (which could
be internal sources like a software instrument) that can be sent to that
output.

To see what input devices you have, run $ arecord -l

The first error seems to say that ALSA is not happy about a period size
of 16 frames.

Maybe you could use Studio-Controls to change that setting to something
else? Studio-Controls is great for trying different settings until it works.
https://help.ubuntu.com/community/UbuntuStudio/UbuntuStudioControls

There is some advice on the settings to use for USB devices there, and
on the previous Pro-Audio link I sent in a previous thread.

Regards,

Ross
