Virtual audio device with URDC-II and Direwolf on Compass #udrc-ii
I wanted to see if anyone else has run into this issue with virtual ALSA devices and Direwolf. I'm aware that virtual devices are experimental, and my config works properly when using the hardware device instead of the virtual device:
Direwolf appears to work fine for receiving, and the first transmission actually works properly. On the second transmission, I receive the error above and direwolf keys the radio with dead air. I rolled back to version 1.4 of direwolf to confirm this error was still present in that version as well. My setup includes a UDRC-II, RPi 3, and Compass Lite 20180701 . I'm using the asound.conf configuration found here a minimal direwolf config.
