After upgrading to 21.1 from 21.0 i experience audio dropouts on video files with AAC codec.
It does also seem to happen on other codecs like Dolby Digital but not that often. Briefly tried DTS-HD and TrueHD/Atmos and they seemed fine.
The Speaker icons on my receiver will flicker when this happens, and i also experienced some big video stutter together with the audio drop out on a video file with AAC.
Did not have this issue on 21.0.
