No Audio when exporting clips

Importing Sony F55 XAVC footage with TC + audio with TC. I auto sync with TC + append tracks, create a timeline from the selected clips, add timeline to render queue as individual source clips with export audio checked to include 10 channels of audio (8 source + 2 synced). Don't hear any audio in the exported ProRes file. Running DaVinci 12 on a macbook pro with yosemite. not sure if it's a bug or if I'm doing something wrong in the new davinci? i've synced on davinci 9 the same way with no issues.

I'm having a similar issue with XAVC-I from an FS7. If export to DNxHR I get no audio. If I export using the ProTools preset I get audio but it is garbled.

I am going to test with 12.3.2 and if it still is broken I will open a ticket with support. I posted to the BMD Resolve forum and got not replies.

is it possible the audio was recorded at 44khz? I know Resolve didn't use to like non 48k audio from wave files...not sure about embedded audio.

[Glenn Sakatch] "is it possible the audio was recorded at 44khz?"

In my case no, I don't think my FS7 will even record at anything but 24/48. I doubt the F55 will either.

I am planning on trying 12.3.2 within the next hour or so and am hoping it is better. I tried opening a case online but it apparently did not complete. If 12.3.2 is not working I will try again or call them tomorrow.

Thanks for the thought,
Robert

Did you find a solution for this. I'm having the same problem with Resolve 12.5 and FS7 files.

Nope, as you noticed, still broken in 12.5b2. I have a support ticket open on it.

Workaround is to export audio separately.

It's ridiculous as the FS7 is very popular and the internal XAVC-I is good/very good if exposed correctly.

Take it EZ,

I did an XAVC F55 project back in January, and I definitely delivered in ProRes 444 with audio. The difference is that I did not use camera audio -- I only used a finished track. I suspect there is some issue with the camera audio if this is internal production sound.

If it's a synced track, I don't see how there could be an issue. Resolve shouldn't treat a WAV file any differently depending on what kind of video is playing back with it. I would call BMD support and see if they can duplicate the problem.

There were versions of Resolve that did handle XAVC-I correctly. Also my testing has mostly been with XAVC-I to DNxHR flavors to send to Avid.

This is especially frustrating since linking (was referred to AMA linking) in Avid and transcoding is also broken. I have two updated pro apps that I BOUGHT and neither handle the best quality native output from my PROFESSIONAL camera properly.

If it was some janky lowend DSLR I could understand it, but as you pointed out, the XAVC-I codec is native to even higher end SONY cameras as well.

Not that it bothers me or anything.

Take it EZ,

Just a workaround: Sony's Catalyst Browse will allow you to take the XAVC files and convert them to ProRes, at least on a Mac...

I went back to Resolve 12.3.2 and it seems to be working much better. 12.5 was all messed up for me, with most everything.

I have the same problem with 5D H.264 footage. Tried all the deliver settings, but shots get delivered with no audio.

I had the same problem before.
But it had been solved when I updated resolve to v12.5.1. I can now deliver prores files with original audio track from sony FS7 mxf.
I thought it might be some kind bug in 12.5.
