Sound problems when streaming from MEGA

Good afternoon, I have the following problem, I subscribe to the Infuse version of PRO (the application itself is the latest available in the Apple Store), the combination of equipment is as follows: Apple TV of the latest generation + MEGA 2 PRO subscription (8TB where my entire film library is located), recently I started to notice that Some films or TV series do not play sound, but the picture runs normally without delays, there is no pattern, some time passes and everything works stably. Firmware version Apple TV OS 17.3, Infuse version 7.6.7, Internet speed 85 - 95 Mb/s. Tell me, has anyone encountered something similar, or can tell me what to do to improve the situation?
