A bit more investigation...
I tried using a USB sound card which shows up on arecord -l as card 2, device 0.? ?The option USB audio... hw:2,0 became available under Recording Options in WxtoIMg. I use this USB sound card to record AX.25 telemetry so I know the card works.
When I tried manual Record, I got an error complaining about the soundcard setting.? "Error can't open audio device -9985...Device unavailable, check soundcard settings in recording options.."? ?
I had selected one of the defaults 11025. I tried the next one 22050 , then 44100 and got the same error.
I also found that using alsamixer, not the GUI allowed me to tab the capture side and increase it with the up-arrow.
Further experiments showed that Default audio, default or pulse would Manual record noise at a level of around 45 with full audio or none going in to the USB card or 3.5mm jack.
