Hello everyone.
I'm using for the first time a Raspberry-Pi 4 that I want to use to do all the digital modes I'm involved with: Winlink, JS8, PSK31.
On learning how to use the Raspbian environment I encountered a problem:  I connected a set of earphones, connected to YouTube and opened a music video, but there is no sound.  Is there a need for High Z phones or something in the software that I need to do?
Thanks and 73,
JP, KW4WA

Did you right-click the speaker icon, and select the appropriate output?

Thanks.  That did it.
