No Audio in files rendered in Davinci Resolve 17 beta.

Happened 3 times now. One project took 1 hr to be rendered and tried again and yet no audio.

It doesnt give any error either. Now trying for the third time, this time exporting as quick time format rather than mp4.

Haven't had any problems with audio yet. Show us the Audio tab of your Deliver settings.

With quick time format selected this time audio was there in the rendered file.
I shall post a snapshot of the audio settings in deliver page.
I have not touched these settings... never felt the need to look into those settings.

I have experienced this as well, mp4 format and Windows 10 machine. Didn't spot the error and uploaded the video! I've since opened the project again and re-exported, same settings and this time the audio was there.

An important step in professional production is to QC the deliverable. There's nothing makes you look more like an amateur than missing obvious errors because you didn't check it before you delivered it.

Always watch the entire exported program on the best quality home theater system you can afford before you hand it off.

My thoughts.

To make you understand in common words, you don't always get your food tested for food poison before you consume your meal.... why because you did fine to now while having food without testing it for toxins...

I reported this audio bug a good few days ago also..

I also ran into the same issue with audio and had to delete and re-import the audio tracks. But it only happened on one audio track and only to audio attached to .MOV all audio attached to .MP4 was fine. I also had an issue with it hanging on render or taking an extremely long time. The fix in my case, was to make sure I moved the play head off of the beginning of the timeline, then it rendered fine and retained the audio.

Today again no audio for the video, but in the end of the video had addded another outro track with audio, it played the outro track fine.

Funny errors n time wasting.
Had to make the project again in filmora 10 witht the same clips and it worked out fine.

Resolve PB 17 introduces options/issues with rendering audio.

Take a look at the Audio tab and pay close attention to the option "Output Track 1". In theory, you should be able to choose "All audio tracks" and this would merge/bus the audio together, but how? Mono? Stereo?

I found choosing this option rendered audio I could hear on my computer, but not after uploading to youtube. On youtube: no audio. Why?

I often have audio track 1 muted, as it's synchronous sound of a video clip, and use other audio track for VO or ADR. I thought this may be root of MY issue.

I decided to manually bus together all audio tracks under Fairlight (excluding the muted track). Under Fairlight, choose Bus Format, add a submix, select the non-muted audio tracks, assign to the Main, and the muted to Submix, then in Render Tab choose that Main as the "Output Track 1".

Another work around: Render all audio (no video) to a .mp4 or .mov *(without video) duplicate the timeline, import the single audio track, delete all audio off the new duplicated timeline, drop in the single audio track, (make sure it's not muted), render video with only one audio track.

(FYI rendering Audio as .wav "single file" outputs individual tracks, so wouldn't work as a workaround for this issue)

This isn't a perfect solution, especially if you WANT more audio tracks than just stereo.
