impulse gun doesnt make blast sound under water with no HD

Interesting... but for me with HD mode underwater, all sounds are echoed longer. Regular mode plays sounds normally, still.

Steps to reproduce:
1. Spawn a pickup - can be sword, impulse, railgun... something that makes a sound you can easily pick out
2. Place a waterplane
3. Enter play mode and pick up pickup
4. Use the pickup several times above and below water - get a feel for what it sounds like in both conditions
5. When out of water, toggle HD mode to be "on"
6. Repeat step #4 again, use the pickup above and below water
-> Above water, the sounds will be identical and there is no change between HD and regular mode. However, when underwater, HD mode causes the sounds to be echoed and played longer and louder. This echoing effect persists until the player has both turned HD mode off AND return above the waterplane.

Siri, could you post your aboutmybrowser link for me? It's working fine on Chrome

Jatsu, what describing sounds like a feature to me to be quite honest. Thanks for the reports though

This is really weird since I use the same setup. Are you absolutely certain that you're not accidentally leaving out some steps? :/
