John and Rob, thanks.? I'll check out those user guides.? And the threads re AT878 and Wouxun on this forum.
Rob, before I implement the changes you suggested, let me try & answer your questions.
USB sound card:? What both aplay -l and arecord -l came back with were 1,0.? (Card 1, device 0)? In line 86, it shows?ADEVICE plughw:1,0. (All I did was remove #)
VOX: I did try Vox=1 on AT878, but this was after it wasn't receiving packets with Vox off. No change. I did not try Vox on Wouxun, because I assumed it was a moot point if it first wouldn't act like an iGate. Is that a fair assumption?
