[M. Sarsfield]

I installed three new 1.5 versions on my machine: Main Back-Up, Copy 1, which is my German version, and Copy 2, which is my US version. I tried the two copies in stock layout playing both US and German on each and I noticed that engine and wave noises are not affected at all by the Sound nor the Master Volume sliders in the SHIV menu. I can completely turn them off by unchecking the Sound check box, but that is it.

I thought under 1.4 that engine and wave noises could be adjusted by these sliders. Maybe this is a 1.5 bug?

I also uninstalled and reinstalled my sound driver, thinking that maybe it had a bug, but that didn't change anything.

Loading sound mods doesn't seem to affect it, either.

When I run TC around 1024 on the map view, I start hearing crackling noises out of the speakers, as well.

Update:

I was thinking that maybe it's due to having multiple installs. I don't remember running into this issue with a single install before. I followed the MultiSH4 directions, though. So, I'm not sure what the deal is.
