Hi,
it seems like the new Sound menu checkboxes added in 2.0.36 are not taken into account during startup.
What did you do?
I went to the sound settings and disabled the checkboxes for "Master" and "Music", like in the following screenshot, then I restarted the game.
What happened?
During startup, the Factorio title music is played. In the main menu and in-game, the sound is muted (as expected).
What did you expect to happen instead?
There should be no sound during startup when the sound menu checkboxes for "Master" and/or "Music" are unchecked.
Does it happen always, once, or sometimes?
I was able to reproduce it, and tested different sound settings.
The startup music is always played when the volume sliders for "Master" and "Music" both have non-zero values, regardless of whether the checkboxes are checked. If I set the volume slider for either "Master" or "Music" to zero, the startup music is not played, again regardless of whether the checkboxes are checked.
In the main menu and in-game, the sound menu checkbox settings are respected.
Further information
I'm using Arch Linux and PulseAudio as the sound system.
