Direwolf issue with Digirig

I am running the newest version of Mint Linux and I have a Digirig connected between my computer and my Xiegu G90 radio. The Digirig is working fine with FLRIG and WSJTX.

Here are some relevant commands:

arecord -l

direwolf -p

Dire Wolf version 1.6

Includes optional support for: gpsd hamlib cm108-ptt

Reading config file direwolf.conf

Audio device for both receive and transmit: plughw:2,0 (channel 0)

Could not open audio device plughw:2,0 for output

Device or resource busy

Pointless to continue without audio device.

Can someone help me resolve this issue?

thank you

Have you listed your audio devices to make sure plughw:2,0 is correct?

yes, I did use the arecord -l command and then set the value in direwolf.conf file.

Could you possibly have a background app that’s using the digirig sound card?

I just rebooted an tried again and everything works as expected!

Thank you
