A loud clicking sound like a speaker or amp being turned on happens while upgrading any base materials.
I've done work in audio and it sounds like a dc error or something clipping really hard not a good sound and kinda concerning for my speakers meters peaked out to max I have a physical read out sitting next to me.
All my sounds for the game are turned off from the in game menus
I'm using a external sound card but haven't had this happen before this last update
Happened 3 times because I wasn't sure what was causing it so I had to make sure.
