MDL Playback Audio Randomly Cuts Out

Hello MuseScore Team. I really love this program and have used it for the past year or so to compose drumline cadences. However, I have experienced errors during playback in MDL. Whenever I play back the audio of a score, the audio cuts in and out. Some of the notes do not play back, and it has become extremely frustrating. For example, if you have written a bar of 16th notes ("1e&a2e&a3e&a4e&a"), during playback you may hear "1e a2e&a a4 &a". It is completely random and unpredictable as to what notes will not play back. It happens whether I press the "Star or Stop Playback" button or the spacebar. With this problem, I thought that at least the full score would play back when I exported it as a WAV audio file, but no. This is also extremely frustrating because I used to export an audio file of a new cadence I composed and send it to my fellow drumline members for feedback, but I cannot do this anymore because the audio cuts out even when exported. This issue greatly takes away from the music composing experience and community.

It may be worth noting that I have noticed that there are only issues with the snare and tenor audio. I have not experienced this with bass or cymbal playback. I always choose "MDL Snare", "MDL Tenors", MDL Bass Line 5", and "MDL Cymbal Line". I do not know if this issue occurs with the other marching percussion instrument choices, but I assume it does.

I am using MuseScore revision 7684abe on a 2012 MacBook Pro with MacOS Mojave 10.14.5 installed (I also noticed these issues on a 2012 iMac running on Mojave). I have attached a MuseScore file of an unfinished cadence I was composing. You will find that when you play back the audio, notes will be dropped inconsistently.

I really hope this issue will be fixed very soon, because I really do love this program. Thank you for your time.

//Update only a few minutes later - The bass audio actually DOES also cut out. It did not the many times I played it back before, but now I am noticing that it does.
