Audio waveforms being cut above certain level

Hi, recently I finally upgraded to DR17.2 after using DR16, everything has been going smooth so far except one thing - when I put quiet audio clips into the timeline and want to raise volume for that specific clip (either using inspector and volume slider or by making keyframe with alt+click and draging up) the waveform is being limited to certain height. Everything above certain level looks like clipped when in reality it isn´t.

What I´ve tried:
Playing arround with timeline / audio view options on the left - no matter what setting I use or what track height do I specify, It is always limited to a certain height, beyond which it doesn´t extend.
Fairlight page shows the same result.
I also tried different clips, different timelines, different projects (empty ones) and also different computer (both Mac and Windows).

As you can see in the attachment, my old projects from DR16 are shown as "clipped" as well but the keyframes are preserved, so is the volume and nothing is audibly clipping. When the waveform is this low I cannot make precise local adjustments of volume which is really frustrating. Please tell me that this is a trivial problem and I´m doing something wrong.

Davinci Resolve 17.2 (studio)

Here is the video example of what it does:

It just jumps down when I first move the volume and then I´m not able to revert it back unless I reimport the media.

This is a problem that has been reported by others. It only seems to affect the waveforms of embedded audio. The actual audio is not affected only its waveform display.

Thank you for your response. I was able to extract audio track (using audacity) and after importing to resolve and syncing it with the video track, it works now as expected. This does not however solve the issue and it is a huge problem for the type of footage I´m dealing with - footage with really inconsistent audio levels. Hope this gets resolved soon, otherwise I will have to revert to DR16.

Is this the same thing as what I get here?
I was ready to make a new thread about that.
I just bumped the volume very high to show the difference between the clips.

The one on the left is AAC LC (see screenshot)

I've noticed the same issue in the display of audio waveforms.

I use them extensively to visually pick out areas that need attention when mixing a project. The visual clipping is very annoying.

I can't replicate the issue on my Mac. This looks like some kind of odd display bug.

I've narrowed the problem down I think

It appears to only effect MP4 clips imported that contain AAC encoded audio. If the clip contains PCM audio it displays fine.

I recorded the same shot on my Canon XF400 and changed the MP4 audio codec between the two formats and the problem vanished for the PCM audio. I don't know if this effects any other formats though.

I don't have this problem at all, including MP4 clips with AAC audio.

Not sure that's the key.

Neither can I reproduce that here, but I'd suggest to stick to uncompressed audio.

Thankfully this issue seems to be fixed in 17.2.1 update.

I can concur with that.

All my projects that exhibited this issue now display waveforms correctly.
