I just used the script to download and build WFView on my Raspberry Pi 400 running Bullseye. I’m connecting to an IC7610. The first time I run the program, the audio is fine, but if I quit the program and restart, the audio is garbled and there are buffer underruns with QTAudio with the message:
ALSA lib pcm.c:8545:(snd_pcm_recover) underrun occured
Powering the 7610 off and on (using the on screen buttons) clears up the underruns.
Rebooting the Pi doesn’t clear up the underruns.
PortAudio and RTAudio don’t seem to have the issue.
