-Just tested different Audio devices and NOT via the Loopback software/device. -And the problem still remains! -J |

This is really mysterious. Solo / Mute really just changes gain of outputs. Ardour processes everything as if nothing is muted and then outputs at active mute-points get a gain factor (Preferences > Monitoring > SiP cut). Is that set to -inf dB? |

@x42 Yes, it is. Screen Shot 2026-02-19 at 12.24.11 PM.png (182,150 bytes) |

Okay, so I WAS able to reproduce this on a VM of Lubuntu, using: PulseAudio Default Playback 48 kHz 2048 Samples -------------------- Steps to reproduce: 1. Create a new project (-whatever sample rate, etc.). 2. Add two audio tracks (Audio 1 and 2) and one audio bus (Bus 1). 3. Disconnect the tracks from the Master bus, but leave Bus 1’s connection to the Master. 4. Add *Aux Sends* from the two tracks to Bus 1, setting each to 0db. 5. *Import* audio to the Source List (-preferably something loud). 6. Drag the audio to track Audio 1. 7. Add the following plugins to Bus 1: • Ace Amplifier (-set to 20db, but bypass it(!)). • Something that produces latency, such as XT-LC Lookahead Compressor. 8. Place the playhead over the audio. 9. Play the audio. 10. In the editor, click the Solo button for *Audio 2*, to which you *should* hear silence. 11. Pause the transport or simply keep it rolling. 12. Open the Ace Amplifier on Bus 1, and un-bypass it to boost the audio by 20db. 13. At this point you should hear a tiny, repetitive loop of audio. But if you don’t… 14. Pause the transport, un-Solo to reset everything, and then try steps 8-12 again but hit Solo for Audio 2 at a particularly loud moment. ... If you STILL don’t hear the loop, then… 15. Go to Audio/MIDI Setup, stop it and start it again, OR stop it, set it to 2048 buffer size, and start it again, then repeat steps 8-12 until you hear it (etc.). -------------------- Additional notes: 1. You might have to attempt this several times, but it should work, unless only my Mac is to blame, somehow. 2. I canNOT reproduce this if you use *direct connections* instead of Aux Sends. |

~Seems to be fixed as of 9.0.110! Probably this commit: https://github.com/Ardour/ardour/commit/e0963ced27c1327ca5ef536d2b9abfe58ad08584 Thanks, @x42! : D -J |

This issue was not fixed in all cases. During editing various sessions since, I have heard this glitch-loop many times (almost literally every time I hit Solo on any track whilst the playhead is rolling). I will test further though (and even repeat my recipe) and see what info. that gives us... Thanks, -J |

@GhostsonAcid Is this issue still the same with you? I've run into it now under different circumstances in a different session: track outputs to the master bus with no aux sends, but only in PFL. I'm going to create a new video, if I can replicate it quickly with a new session. I'm wondering if I should close https://tracker.ardour.org/view.php?id=10223 as a dup. |

• Something that produces latency, such as XT-LC Lookahead Compressor. Have you added it before or after the send? Are the aux-sends pre or post fader? While automated mute (touch, play) is latency compensated, user initiated mute/solo happens instantly. So the it seems as if the issue here is that LC to plays back delayed audio from its internal buffer. |

I replicated the issue in a fresh session without using aux sends: https://www.youtube.com/watch?v=cLnUTJe6x-0 Also, when I tested it with the aux sends, I believe I experienced the same issue with automated mute and manual mute. I can test further if you need confirmation of anything. I can't access the other issue (https://tracker.ardour.org/view.php?id=10223), perhaps because it's been marked as a duplicate? |

(The problem I had accessing the other issue went away with a logout and cache clear.) |

@mkindred "Is this issue still the same with you?" -Yes, I am still getting it. But it's hard/harder for me to get the effect which such emphasis/loudness as you have in your videos. Also, I was just now able to replicate the results in that second video of yours (i.e. without using Aux Sends). @x42 I will try to get back to you on this later this evening, and setup another recipe, etc., etc... -Been very busy lately with other things... : / |
