[LAU] Any success running Jack on a Chromebook that's running Crouton?

Hi all,

I have a Acer C720 Chromebook, and I run Debian Stretch on it using a
hybrid OS approach using a technology called Crouton (
https://github.com/dnschneid/crouton ).

It runs some kind of audio server proxy called Cras to get the audio
from ChromeOS into Debian, and I have been unable to get Jack running
with it.

I'm wondering if anyone has any hints or success stories about running
Jack and/or Ardour in a similar environment.

I get a permission denied error (on /dev/sng/seq) when trying to start
jack using qjackctl with ALSA midi seq enabled. If I disable MIDI
support, I get "control open "hw:0" (No such file or directory)" and
"ALSA lib pcm_hw:1701:( snd_pcm_hw_open) Invalid value for card"

I would like to do some audio production on the chromebook, or at
least get that stuff running to see if the performance for that would
be acceptible.

Let me know what other information I should provide to try to get this working.

Regards,
Jeremy Carter
