I'm working on a pd patch using pi 4. I bought small audio interface UGREEN. Connect it to my pi 4 and it seems to recognized it but no sound is coming out. I try both play file via vlc, via pd and via YouTube (the video is stuck and not playing at all).
I try to change the alsamixer setting following that link but it seems it is not storing my new setting.
Anyone encounter that?
How can I fix that issue?
