I'm having some trouble understanding why the CLI pa command "pa devlist" returns ERR unless I'm running it under root. I installed on an ARM single board computer over the weekend from the ARM repository following the instructions for raspberry pi. I can use aplay from the command line to play the music on hold wav files included with FS. I've plugged in a USB sound card device and made it the default sound device and rebooted. Same result. The OS image is dietpi and there's no other running processes running that use sound. I saw alsactl running and killed it, restarted FS service, but still no devlist. Looking back through emails here in the list, there seem to be similar questions over the years, but with no solve that I found. Does anybody have first hand experience with this? I'm away from home, but I can follow this up with some console output it if helps. I'm trying to set up a loudspeaker paging device. Tom
