There is a bug with the last Botania version wich cause some ambiance sounds from Dynamic Surroundings like the birds to bug and repeat them indefinitely.

I'm seeing a similar issue with the elevator from rfTools and the generator from DeepResonance that started after Botania r316. If I remove Botania or downgrade it to r316, the sound repeating indefinitely issue is abated entirely.

The only other way after r316 to get the noises to stop is to remove the block that causes them. We also do not have any Bergamutes on the server or the test clients.

Discussed here: McJtyMods/DeepResonance#113

As a workaround that doesn't require you to reset anything, mute your block sounds for a second and turn them back on, the audio is fixed until the next time you use those items.

fixed in next release, thanks for your patience

Are you sure it is fixed for real? I'm getting reports on it again in release 320 of botania:

McJtyMods/RFTools#703 (comment)

It's not in a release build yet. I'll probably put out a final build of Botania U within the next couple days now that vaz is back
