Today’s 8.1.6 update includes a set of changes to improve the behavior if/when this issue appears.
Unfortunately, the core issue is a system bug related to how Apple handles some Atmos content and a fix will likely need to be made by Apple.
The next update will include a toggle for Dolby Atmos within Infuse, which would allow you to avoid the issue entirely by playing the affected files in multichannel audio mode instead of full Dolby Atmos. This toggle would also allow for features such as Volume Boost to work with Dolby Atmos content.
Thanks for your patience.
