In Infuse 7 1080p mkv is the sound out of sync with Homepod pair


I bought Infuse 7 yesterday for one year. Unfortunately I found that mkv files in 1080p do not run in sync on my Apple TV with 2 homepods. The audio/video is < 1 second out of sync. It has not been noticed with other formats. With VLC the problem does not occur with the same files. Other apps like Netfix or Prime Video are also absolutely synchronous. What can I do to fix this problem?

Best regards
