Master Channel Suddenly Not Working In Only One Project

[vongol]

Hey, folks.

So, a strange and frustrating problem just arose out of the blue after I closed LMMS and reopened it later: there is no longer any sound, but what is absolutely bizarre about this problem is that this is the case in only one project I have been working on; when I open a new project, there is sound. Upon closer inspection of said project, I noticed that the master channel in the mixer isn't working, while the other channels are both working and routed to the master channel.

I am absolutely stumped at this point. I reinstalled LMMS, yet this did nothing; I changed the sound card to SDL, but this didn't work either; and I also removed all the channels from the mixer to start anew, but that didn't work either, and this normally causes LMMS to freeze anyway before I get to even complete my changes.

What the hell is going on?

Try this. Right click the master fader and choose 'Remove global automation'.

Good thinking.
But i dont like this:

What version of lmms do you use on witch OS?

Did zm's tip, on global-automation, help you?
Normally only imported midi will lead to that issue.
Did you import midi?
