Sound issue at the beginning of clips

Hello,

I have a weird sound issue which may have occured since I've installed version 22H2 of Windows 11, but I might be wrong.

When I put a clip, which has sound, in my timeline, and press "play", often the sound remains silent until 1 to 5 seconds has passed and then for the rest of the clip, then sound works ok.
Then, if I go back to the begining and replay the clip, sometimes the sound works immediately, sometimes it remains silent for a few seconds and work again. Often the amount of "silent time" isn't the same.
The big problem is that it also does the same when I render the clip.
It is sometimes visible in the visual audio peaks (which looks empty for the few firsts seconds), and sometimes not.

It seems random with each play attempt and render attempt.
It seems to affect only clips which have been rendered by resolve (in the past or present version, and also from other people resolve versions).
I seem to have no issue with clips which have been created by a camera or by using things like youtube download videos stuff.

I've never had this issue before using resolve for 3 years.
I've tried a work around in the form of rendering "audio only" then re-attaching this new audio to the video but unfortunately the rendered audio does the same random error.
It's always the first few seconds of a clip, sometimes like 0.5 seconds.

Resolve version: 17.4.6 BUILD 4
Windows 11 v. 22h2
I also recently updated the newest NVIDIA drivers.
My sound card is a Steinberg UR22 MKII.
I work and render in full HD or 4K at 60fps.

Should I try to delete all cache files, or install resolve 18. I don't know.
I have a windows save prior to the 22h2, but I'm not sure how to revert back to it (never done this before).

Anyone has experience with this issue ?

Any ideas ?

Update to version 18.1.2.

SOP backup procedures, first.

The playback delay has been common on some systems for many years. It usually corrects itself if you stop playback and restart, as if the system is buffering itself.

However, if the material is exporting with missing starting audio, that's a whole other issue. Can you provide any clips which behave in this way?

The clips work perfectly if I read it on windows media or upload it on youtube.

But now, if I put those clips in my timeline, resolve just "interprets" it badly.

I playback and restart a clip 10 times:
2 times the sound worked ok
4 times there was a silence of multiple (variable) seconds then the sounds kicks in
4 times I could hear the sound from my right ear for a few secs, then the full sound kicks in.
And if do 10 tests renders, it will have those same random results.

So yeah, it's like that old little sound buffer delay (happens when you open resolve, or read a big clip) that fixes itself after a single restart playblack. But here, it's on steroids, it affects renders and it doesn't fix itself, it's random.

I decided to update to the latest 18.1.2 version of Resolve
and it fixed the problem ! I'm happy. New resolve looks nice.

How do you find 18.1.2 generally - I am considering upgrading but Id rather not get stuck with bugs.
