If no solution: Deactivate the headphone audio device. |

So will there ever be support to output audio from the headphone jack on the Pi 4 ? |

@DavidOpgh I need to check again with the new version. However, we had complaints about the quality in the past anyway. Seems like the headphone jack is not well suited for public audiences. I would therefore anyway recommend a separate audio interface for serious applications. |

Yes, I understand the audio from the headphone jack would be inferior to a
separate audio interface but while developing in the prototype phase it
would be helpful to have the option.

Playing it with
aplay -D rocketshow xy.zwavworks fine. Seems to be a Gstreamer issue. Maybe update Gstreamer and try again?The text was updated successfully, but these errors were encountered:
