'enjoy' weird bug...
Start playback in piano-roll
There will be no sound from 3oc track
Let it play
Toggle BB-line-1 ON in Song-editor
Now 3oc can be heard
Toggle BB-line-1 OFF in Song-editor
There will be no sound from 3oc track
Delete BB-line-1
Now 3oc can be heard
-There is some kind of dependency between the BB-track, and the 3oc track.
The 'project' had 15 other tracks. They were removed one by one, untill i found this dependency.

Cannot reproduce 1.0.3 win64 or 1.0.9x win64.

I've had this happen before in songs with tracks where various automations are applied. The first playthrough will have the track either be silent or with various settings not correct for that track. However after letting the song play completely, playing it again produces the correct sound.

Not sure why initial values aren't correct, but playthrough somehow picks it up and resets it.

I'd also consider this a fairly old bug. Was in some versions before 1.0

If you use automations, you have to automate throughout the song, or at
least set the initial value for each control manually by adding
automations at the start of the song. LMMS doesn't automatically
remember any control values, if you don't set them, they'll just be
whatever they happen to be at the moment you press play.
