Hello Mike,
Few basic questions:
?? 1. Are you running PulseAudio on your Raspberry PI's?? It's
generally not recommended for these low end computers and it's
recommended to uninstall it.?
?? 2. When you say you have some soundcards working well and "new
same" sound cards that perform poorly.? Which sound devices are
these?? Can you swap out a bad unit for a known good unit and
prove that the problem follows the sound card?
????? 2.a.? If the problem follows the sound card, capture the
output of "sudo lsusb -vvvv" for both the bad and good cards.?
Send us the difference here to see if the cards are seen
identically or not
Ps.? I see you're working with Direwolf here.? Your email here was
a bit vague, your screen shot also showed errors with AGW/PE,
etc.?? If you're using Bluetooth with Aprsdroid and Direwolf,
there was a newer APK posted on the the AprsDroid site addressing
some TCP-KISS issues:
