I can't recreate this at all along with any of my other testers.

Can you give me a little information more, is it on every part of the map, some?

It looks like there's a bug on the source engine that means ambient sound is taking up sound channels from any range, even when unheard. I think the max sound channels is in the 100s, and I've only 10-15 on my map, but it could still possibly cause this issue rarely.

No problem, in next release I will clean up the sound so as to be created via one soundscape with locations. With this I should be able to bring the number of channels used down.

Until then, I can only advise that I've heard of people on csgo fixing this by swapping audio settings back and forth. Other than that perhaps clear sound cache (snd_reloadcache). Maybe it counts for something

Thank you for the report, you can expect a permanent fix on the next version. (beta 1)

I've only had this problem with one other map before, I forget if it was soundscapes or ambient sounds so I ended up using stripper:source to remove anything that plays sound lol. (Which fixed it).

(I vaguely remember it was probably soundscapes).

Next time I play the map I'll try to figure out where it's happening.

Seems to depend on how many players around, I don't get this kinda glitch on other maps though.

Alright np. Same as before, I'll clean it up to use a bit less. Thanks again, on beta it will be fixed for sure.

Alright. for this next release I've brought the ambient sounds down by about 60% - this should be the final before alpha ends. It should release tomorrow or day after, for a test day coming soon, please let me know if you still experience the issue.
