Description:
The mod have been existed in my modpack for a while, but I just did a full update to all mods. This particular crash related to a SoundManager did NOT happen before the update, but there was another unknown crash related to entity updates (NullReferenceException). That crash disappeared after the update, though. (or it did not, because the world is new)
I have a couple of versions of the pack, which changes how heavy the client is. This crash happens only with the heaviest version (Ultra) which also have AmbientSounds and SoundFilters installed. They might be related OR cause it, I can't tell what mod actually causes this.
Reasons why I think the crash is caused by your mod:
The Medium version had reported to never crash by users, and that version does not have these three mods installed. As far as I know, the High version too have not crashed and it have everything else but Dynamic Surroundings installed. That's why I'm reporting this crash here.
Is the modpack you are using available online somewhere?
Yes and no, the packs are integrated with a custom launcher.
Some other errors reported in the log:
This one will show up sporadically after the initial flurry of reports:

Not sure if this is a result of the failed load:

This exception is related to the fact that a non-client thread was interacting with sound manager which is a big no-no. DS interacts heavily with the sound manager doing its sound management, but all that occurs on the client thread. So if another thread is indeed accessing the list at the same time you can get this exception.
"Unknown" NullPointerException is very old crash, we have suffered from it about 1-2 years now, because nobody knows how to fix it or what causes it. Back then when it first occured Weather was not installed.
Weather mod NullPointerException happens because of the Menu Mobs mod, not sure why though. It spams that when on a main menu, nothing dangerous.
What do you recommend to do at my situation? I have now two "unknown" crashes, one related to sounds and one related to entities.
Try this: https://dynamicsurroundings.readthedocs.io/en/master/debugging.html It may give more details as to what is going on.
@LiskoSlayer63 Its been a bit and I was wondering if you tried out enabling the diagnostic feature in DS.
@OreCruncher I actually forgot this whole problem, it seems to have disappeared now. I had LiteLoader installed for a long time, but then updated the modpack to use Forge only. That fixed many problems and crashes, maybe this one too. I will enable that diagnostic feature and open a new issue (or revive this) if the problem appears again.
