I wouldn't say happy, but at least I got to understand what the |

interface does (I was more or less convinced the RCA part was broken!) |

The MB card. |

When using modules you can blacklist other sound cards (the MB audio stuff for instance) and you get a little more visibility into what's is at least loaded. That way we could, at least as a test, run your setup as a USB only system. If at that point you can record mix audio in something like Audacity and play Audacity and Youtube through the Behringer then, I would think, we would have determined that this is an application issue. |

Will try that, why not? (Tomorrow morning) |

I tried discord; I heard the sound, the other side didn't. |

I'm now compiling zoom, after removing the ~amd64 from the ebuild (I |

will not have an unstable qt all over my system). We'll see... |
