|Fixed in Version|
|Summary||0008193: No sound when you open a ardour project with pulseaudio|
|Description||There's no sound when you open a project that you made if you use pulseaudio. The way to get the sound back is to go to Window -> Audio/Midi setup and then you need to stop and then start pulseaudio again to be able to hear sound in the ardour project.|
|Steps To Reproduce||Make a ardour project with the pulseaudio backend and add any LV2 plugin that produces sound before you save the project and close ardour.|
Open ardour again and then there's no sound in a midi track that you've recorded for example neither if you try to use the virtual midi keyboard.
You need to use my workaround to get the sound again.
|Tags||No tags attached.|
||I cannot reproduce this.|
||It seems like this happens in alsa backend also, i get the same problem on compiled ardour, binary arch ardour and the ardour official demo. Its easy to fix by restarting the audio engine but i got no clue why it doesn't just work when you start ardour and open your project.|
Odd that it happens with ALSA, too. Perhaps an issue with configuring the soundcard (sample-rate, buffersize changes)?
Regarding Pulse, could you try 6.0.59 (or later)? I've slightly changed initialization sequence. Perhaps that helps
||How do i test the 6.0.59 version? Is it the ardour version you mean and do i need to compile it then?|
||Yes, either compile it, get a demo from https://nightly.ardour.org|
It is still not working when you open a project and you still need to manually restart the audio engine to get ardors audio to work again.
The plugin is also black everytime this bug happens until you restart the audio engine and ardour sound works again.
I found a quite interesting thing, this is the error when you first open a project and get no sound.

I have solved the issue, i know what the cause is now.
I use this https://imgur.com/qSznmtg.png to record midi with my computer keyboard and record some midi parts and then i save my project and close ardour. When i open ardour again then i get no sound because that midi input to midi output thing is still on from when i saved the project. If you turn it off before you save your project then you can open ardour and get sound directly. I think ardour should do that it doesn't save the midi input to output state as connected by default when you open a project.
"I think ardour should do that it doesn't save the midi input to output state as connected by default when you open a project."
You may think this, but I am absolutely certain that almost all of our other users would disagree.
