Hi Brian184,
My name is Jackson, thanks for your question.
We sincerely apologize for any issues you may be experiencing with your Teams App. I'm a user and don't work for Microsoft, so I understand how frustrating this can be.
If your computer is running a lot of applications, you may experience issues with sound quality, like lagging or cutting out. If this happens, closing other applications can help and also ensure you have a stable internet connection. and disconnect form any peripheral device and try using Teams again.
You can fix issues in Teams by clearing the Teams cache on your device. follow the steps in the link below to clear your Teams cache for Mac.

Also, if you use the Teams desktop you can try the web version as a workaround to see if it works well on the web. Open a web browser (Chrome/Edge) and go to https://teams.microsoft.com/.
After all the above steps if the issue persist you can give this feedback to the developer Teams using the feedback steps in the link;
