Thanks for the reports. Can you add some detail on the audio codecs and the Audio I/O and peripherals you use? As well as any patching and effect info on clips or tracks that may be pertinent?
Please also mention what your Preferences dialog > Fairlight preferences and Audio I/O settings are.
Thanks

Sorry for the delay. This is now my third attempt to provide the extra information. The forum app timed out while collecting the information and blocked me from posting. I couldn't even save what I had written so I have had to start again.
CodecsShort answer - standard BRAW. That is Linear PCM; 48000Hz; 2 Ch
Detailed answer
This was a 3 hour conference recorded on an ATEM Mini Extreme with 1 x BMPCC and 2 x Studio Camera 4K Pro. The plan was to do an initial edit with the ATEM during the conference. Transfer the drp etc. over to my workstation and complete the edit there on Resolve.
We got a feed from the House PA and connected that to Ch 1 on one of the Studio cams. The other channel was ambient sound using the internal mic. Same for the other 2 cameras. We controlled recording through the ATEM so have braw copies on the cameras, mp4 copies on the ATEM, plus an mp4 of the "stream" which was our rough cut edit on the night.
In post, I copied all the files including the drp to the workstation, fired up Resolve and opened the project. The default timeline had mp4 video and audio. Duplicated that to a new timeline for editing purposes. As intended, the default audio track was replaced by the audio from the Studio Cam which had the house feed. Before copying the audio to the timeline, the audio on the clip was changed. 2 mono tracks were added. 1 for the ambient sound and 1 for the house feed. This meant a total of 3 tracks. 1 stereo from the original recording and 2 mono which were the individual tracks from the original recording. The mono house feed track was copied to the timeline to replace the default track. I also had to copy the mono ambient track to get around issues with the house feed for the first 9 minutes. (They had extra music coming through that wasn't supposed to be there!)
This was all playing normally on 18.1 When I upgraded to 18.1.1 was when the problems started.
EffectsNone - not even compression and EQ! Still early stages in editing.
Audio I/ONothing was explicitly changed away from Resolve defaults.
Both tracks are patched to Bus 1
Bus 1 L & R patched to Jabra Evolve Link Headphones - situation normal for me.
Fairlight PreferencesUnchanged at default settings.
Other comments1. Since my last post, I have gone back to the original timeline using the mp4 files, and there is no issue with delays.
2. I have also checked the audio in the Fairlight page and there is only minimal delay there. Normally the audio starts playing when I push down on the space bar. In this project using the braw audio, it waited until the spacebar key was released before playing. A minor, but still noticeable delay.
Hope this helps.
Again apologies for the delay, but it has been very frustrating trying to get this post completed in the forum app. I have ended up typing it up in a text editor and copying it over.
Thanks,
Darryl
