I checked now if Premiere is lacking support for AC3 in AVI (as you mentioned), and indeed Premiere doesn't like AC3 in AVI. I remuxed the 1 minute M2TS (H264+AC3) video to AVI, using Avidemux and Video Containers Changer, and these AVI files has the same loud noise in Premiere.
Because I prefer deinterlacing to FFV1 (smaller than UT Video and FFvHuff, and only a little bigger than x264 lossless) and AVI is needed for Premiere, I'll replace in timeline the loud noise with either the original AC3 sound from M2TS, or with the WAV edited sound in Izotope RX (I always edit the sound). Or, now that I learned that Premiere doesn't like AC3 in AVI, I can import in Premiere FFV1+FLAC/WAV in AVI, after AC3 is encoded with Hybrid to FLAC or WAV. Other option, x264 lossless in MP4, can be imported in Premiere, and AC3 is supported in MP4 (AC3 muxed with MP4Box in MP4 with Hybrid has sound in Premierex).
In future, Premiere will have to add back the support for MKV (that was removed in the 2019 version); at "How can we improve Premiere Pro?" forum, "Restore MKV Format Support" is the second requested feature (883 votes now), after "Support Blackmagic RAW" (1628 votes).
