I have Klipsh Fives active speakers that i connected directly to the Pi 4 via the USB 2 port. The set up used to work a treat. However, I updated the system a about month ago and did not test the sound until today. Today nothing came out of the speakers. It said another update was ready, so I installed that. Still no sound. Volumio does detect the speakers however and they show up in the settings. It looks like it was working before the last 2 or so updates - currently on 3.378. The speakers use a Savitech SA9226 chip. I tested the USB input with a Linux laptop and it worked fine. So I am puzzled as to why it stopped working.
I would really appreciate any help.
