Thank you for reporting this bug in the "Emerald Mine Club" level collection, which I can confirm.
I have fixed this problem and just released an updated level collection (version 3.2.0), which also contains a brand new Emerald Mine style level set (well, it was already released in 2023, but was not contained in the EMC level collection yet).
I have also improved looping sounds for the activated robot wheel, the waiting yamyam and the active magic wall, which sound like in the original game now.
So please replace the EMC collection with the latest version, which should fix these bugs!
