Whereas Port Townsend shows (even after a Dataplicity reboot):
card 0: pisound [pisound], device 0: PS-3KF2GYN snd-soc-dummy-dai-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0
from orcanode.

Will look into fixing this by adding support for device names, i.e. pisound instead of numbers
from orcanode.

At least for rapsberry pi with pisound card and jack you can just use AUDIO_HW_ID=pisound
from orcanode.

Just noting for the historical record this happened yesterday at the Bush Point node (for the first time I think) upon a power outage on Whidbey Island. arecord -l showed 0,0 but .env file variable expected 1,0 ... Re-booting Rpi via Dataplicity solved the issue; when it came back online arecord -l showed the expected 1,0.
