random no audio playback in timeline and with export with Sony MTS files (H264)

With V22.3 I have strange problems with audio when editing HD 1080i files

- first I can edit clips in a timeline with audio but after a while I can't get audio playback on that sequence anymore. (audiometer don't show any audio)

Audio files are showing waveform but the clips of the timeline don't play with audio anymore in timeline

and source window.

While other sequences in the same project still play ok with audio.

When this problem happens, I tried following things

- created a new sequence from clip result no audio no meters

- opened that clip in the source window, no audio, no meters, waveform showed audio however

When I have audio with playback in the sequence it still can happen that I don't have audio in the output render.

I don't have seen this problem with earlier versions then V22.1.2
