Dear all,
I am using Debian Buster on a Beaglebone Black, using C-Media chipset USB Soundcard, under Direwolf application as APRS Gateway.
I noticed that after several minutes I got an error “Audio input device 0 error code -19: no such device” followed with several lines of “Audio input device 0 error code -77: File descriptor in bad state”
This made Direwolf quit working.
It seemed that there was a USB disconnect event (nobody touch the board), so anybody knows how to resolve this problem?
Please note the USB sound card worked fine in the previous location on a Raspi 3B, I moved to this BBB as I have another plan for the RPi.
Sincerely, Yono
