Embedded audio broken after linking to external audio

I'm using a BMPCC6k with a XLR shotgun mic on the left channel, and the camera's internal mics combined to the right channel. For a recent recording, I also had a field recorder hooked up to a lav mic, recording at 96k.

On initially importing the .braw files, Resolve 17 ("17.0B Build 23") correctly shows them as having two 48k channels, and on playback, these channels span the entirety of the recording duration.

After I link the field recorder audio, the metadata _for the braw file_ shows only one channel. That metadata also still shows "48k". However, when I go into "Clip Attributes" and select an embedded channel, it plays back at double speed, ending halfway through the clip.

What I _want_ to deliver is three separate audio tracks, all in sync with each other; this issue means I'm needing to do the synchronization manually. Is there a way to avoid it?

(I also haven't yet determined how to generate more than one linked audio track with content from the same input video, but... one thing at a time).

When you synced, did you Append the audio?

Doing so will retain the camera's original audio. Otherwise that gets replaced by the new audio file.

Thank you! I misinterpreted what "append" would mean in this circumstance; the actual behavior is exactly what I'm looking for.
