The instructions do not call for a play -l until configuring the sound card. The instructions link you posted is the one I used twice to configure the Draws Hat on a rPi 3b.
I ran the ax25-start, then ax25-status and ax25-status -d per the instructions on a fresh install and got the errors in my first post. Both attempts were connected to a FT-857d, using my wireless connection found by the ifconfig command.
I used the image labeled draws-beta13.img, and received my Draws Hat on July 6th. On another rPi with a Signalink USB (without the Hat), I had no problems setting up Direwolf.
No new information from you to comment on. I'm guessing the tlv320aic driver is not loading for some reason. The output of showudrc.sh would confirm that.
Unfortunately this is my last post for a week or so. /Basil
