I bought an early version of the Picade back in December 2015.
After many years without an issue, I thought that it was time to upgrade to the latest RetroPie version, as the legacy Raspbian Stretch is no more maintained.
Everything went smoothly except for one single issue which I have not been able to solve, even after spending a few hours testing it in many ways: my Picade delivers no sound anymore!
The issue is not only with RetroPie but a general one. Fors instance omxplayer can play a mp3 file but no sound exits from the speakers connected to the headphone jack on the Picade hat.
My guess is that the issue has something to do with the Picade hat and sound drivers in Buster.
My model is a blue one and connects via USB.
Did anyone here face the same no sound issue, and by chance found a fix for upgrading these early Picade versions to the latest Raspbian Buster based RetroPie?
