Hello to the devs of mekanism.
I would like to complain about the Basic/Adv/Elite smelting factory being silent. This is not the case as before installing any tier (Enegized smelter) to it, it produces sounds. This disapoints me a lot since I pretty much is a fan of industrial sounds and noises. I never ever have used the muffler upgrade even once. So please look into this problem and fix it. Thanks in advance.

I have also had this happen to me too when I have a lot of other machines, My jetpack is also silent

Well your case is different as your case might be because as too many machines are running your speakers cannot do
multi-sounding. Whereas my case here is that the smelting factory is being silent even when being used alone.

I have tested it by itself, it still produces no sound for some reason

After attempting to reproduce this and having issues, I managed to reproduce it. I believe factories do not start their sound for some reason if upgraded (from a machine that is working with sound) they will stop playing sound until replaced. I will try to track it down so that a fix can be included in 9.8.2

Thanks
