I have UHD 60p H264 video clips with AAC audio. When I bring them into Vegas Pro 14 and put them on the timeline they play fine and I hear the audio track. They also render fine, with audio.
When I bring the same clips into Vegas Pro 15 I hear no audio on the timeline, the meters show nothing and the rendered video (XAVC S) has no audio. What is going on. The settings in 15 and 14 appear to be the same.
There is a fix for this (see a post under video, about avc problems), which entails disabling the new avc encoder in 15 that replaced the old one in 14. This new encoder is responsible for many of the new features we paid for. Turns out it also results in a major reduction in functionality. Disabling it gets us back to 14!
hmmm, I just tried render to Sony XAVC / XAVC S > XAVC S Long 1920x1080-29.97p settings, and then bring the rendered media back to VP15 timeline... I got the audio working as expected..
Can you share your short UHD 60p H264 clip with AAC Audio somewhere like Dropbox / Google Drive / WeTransfer / etc. ? I want to test and also forward it to developers.
This is a link to a clip: UHD 60P, AVC, AAC stereo audio. (WeTransfer)
The audio level of this file is very low (about - 48 dB). But – yes – the audio is distorted in VP15 (it isn't in VP14).
Edit:
Even worse: If I then disable the So4 Compound Reader for AVC/M2TS and try to restart a saved project which contains this file VP15 crashes at startup and it would even crash then if I try to start an empty new project. I need to reset Vegas Pro before it works again.
Further investigation: A simple (ffmpeg based) rewrap of this very file solved the audio problem (without disabling the AVC reader).

This did not happen to me. No crashes. After disabling So4, I can load project files fine, including video files that did not work properly in 15 before disabling and projects that include video files from other cameras. I do not need to reset Vegas Pro, and I do not need to rewrap all my videos. Of course, I cannot take advantage of any of the new features supposed to be offered by So4.
YIxxxxxx.MP4 ? Xiaomi Yi 4K+ Action Cam?
This similar issue is reported by someone else a few days ago... Will forward your sample to developers. Thanks.

Yes. Thanks. Others have reported audio issues for sure, but I do not know what cameras they were using.
"Of course, I cannot take advantage of any of the new features supposed to be offered by So4."
This is why maybe re-wrapping these files may be preferred over disabling the so4 compound reader. Re-wrapping is very fast.

It fixes the audio but the playback smoothness is awful, also from the other Xiaomi Yi file after rewrapping.
This is true. Re-wrapping only fixes the audio issue not the playback performance issue.
