Strangly I can't hear them anymore. When I first downloaded it I could here them, and since then I haven't tampered with my sound card or sound settings. I can hear distant MG sounds though.
I found that sometimes you just don't hear them.
The ultimate test is to start up a local game of Omaha Charlie Sector and use the axis mortars right behind the bunkers. With no other players or sounds distracting you, you will be able to hear the whistle.
If that doesn't work, redownload the pack.
I tried them on omaha, they work. Thanks! I was wondering because I was playing carentan and I couldn't hear them.
Up the number of channels in sound settings?
I just did that. Will that let me hear the sounds better? Also, should I presst the "Hardware Acceleration" button?
Carentan might have a custom mortar sound. It will overwrite anything else.
This may seem like an ass thing to say... but GOOD! Hearing mortars from across the map (the tube sound) was really really annoying and made you want to grab a K98 instead of actually using the richness and depth available in FH because you'd rather not be hunted because your launch sound could be heard for miles.
It's the whistling sound he's talking about... ;) @foodmaniac - increasing the channels (I think) means your computer plays more sounds at once. Obviously this may cause a decrease in performance. You can press the "Hardware Acceleration" button but I think for most people it is buggy and causes a loss in sound quality and things like the footstep sound not playing.
