Hello @AlanaTreppler,
Thanks for your message. The issue has to do with the AC3 audio format used in AVCHD recordings. It is obsolete.
Please see user @RjL190365's response here.
Since version 2017.1.4, Adobe no longer included an AC3 decoder or encoder due to Dolby Laboratories' increasingly restrictive licensing rules....
So, on MacOS newer versions of Premiere Pro now no longer support AC3 audio at all without the installation of a third-party audio plugin.
The Dolby suite for MacOS has

Apologies @lflegg (and everyone else) for the typo. Just to clarify, Resolve was NOT able to do it. I would go back and correct it but I no longer have acess to the profile I wrote that under.

Someone suggested using handbrake to transcode / convert footage to constant frames ... this worked for me . But hoping there is better solution from Panasonic or Adobe

Hello @AlanaTreppler,

The Dolby suite for MacOS has not been updated much since 2017, and is not guaranteed to work properly on an Apple-silicon Mac.
In other words, AVCHD is now considered obsolete by the video recording industry. Newer consumer camcorders record in regular H.264 (not AVCHD) format, with audio now encoded as AAC instead of AC3.
Dolby indicates that AC3 is supported on macOS; however: https://developer.dolby.com/platforms/apple/macos/os-support/
I'm afraid Windows users might also be having trouble with AC3 audio. From what I recall, the OS is supposed to support AC3 audio.
I advise copying the entire contents of your Private folder to your HD and importing via Media Browser to see if that works for you. This has worked for other users. All card-based media should be imported to Premiere Pro in this fashion.
If that won't work, try exploring other format options for the camcorder or purchasing a newer device.
Thanks,
Kevin

Appreciate the first direct answer . And it seems credible . Easy for u to say to replace a perfectly good $3500 camera . Not happy with ADOBE and PP.

If you use Shutter Encoder (donationware) to transcode the MTS streams of the AVCHD data structure to ProRes (ProRes 422 LT, ProRes 422, or ProRes 422 HQ), the resulting files should play fine in Premiere Pro. In the current version of Shutter Encoder, we can preview the file and check lip sync before transcoding it.
For organization, I copy the AVCHD folders to a "Camera Originals" folder and transcode to a folder called "Source Footage".

Sorry, @RobertRNPinc59.
I didn't mean to be flippant. I understand a new camcorder can be super expensive.
Can you shoot a format and avoid AC3 audio? If you provide the camera model, we can help you check. I hope we can help you.
Thanks,
Kevin
