Blackmagic Forum

hi together,
this is my first question and im a newbie...

if i play in my Timeline the Video, my Audio isnt clear. It croaks and creaks.
If i play the Video in the preview all is ok.

Im useing b15.4 for Windows
The Audio is AC3 48Khz

I hope for help

best regards

You have audio, so you're ahead of me. But to me it sounds like your timeline frame rate is different than your source frame rate. I heard similar things when I chose to ignore the suggestion to adjust the project based on source footage. For some reason, which others have mentioned but I don't recall, you can't change the timeline rate except as suggested by that pop up. So you'll have to create a new project and follow that advice. If you have varying frame rates between clips on a single project, fix the variances first. Unless of course you intentionally want the varying clip to be faster or slower on the final render.

The source preview is playing the file as is, which would sound normal.

...and do give us reasonably-full computer system specifications and full, accurate name of your computer's operating System
so we can better assist you please.

Note my system specs and full OS name are readable to you, as I had so established as my Forum Profile "Signature" accordingly.

(It's revealed below).
You (and Newbies here reading this) might do well to do the same, to facilitate getting speedier, meaningful assistance from this fine user community.

Set up your "Signature" from the Forum's Control Panel.

Now, as to your quirky audio playback issue, make sure your computer's Audio Driver PLAYBACK settings -- for the specific Audio Device you want to be using, are properly matched to the very audio settings you've established in Resolve's Project Settings > (General Options is it?)*
If I'm wrong on thar path, try looking in Davinci Resolve > Preferences for audio Settings.

In short, make them suitable for your audio device's playback settings abd vice versa.
Also

Make sure on the EDIT page, the menu item
PLAYBACK > PERFORMANCE MODE is checked (it toggles on or off by clicking once on it and is alternately confirmed by a visible checkmark to the left)

If on PC, ASIO an Audio driver is likely your best option performance-wise

*I'm not absolutely sure about the path for Audio settings as I'm not near my Resolve workstation at the moment.

With System Specs let us know if this did not help.
Cheers!

Same problem here, bur in Timeline and preview too.
Manjaro Linux.
PCM 16bits

I have found that Davinci Resolve can't use the cards ASIO driver. So if your audio card uses ASIO make sure you open your audio cards control panel and look at the sample rate settings, a common setting is 48khz and not 44.1khz.

thanks for your help, but nothing was helbful

Is it sounding wrong in the edit page and the Fairlight page?

long shot... but make sure your playback and timeline frame rate is set correctly to the frame rate thats recorded, 24/25/50

Best of luck

its the same in Edit and Fairlight Tab

What sound card and settings are you using?
Also on delivery how is it sounding after rendering out?

hi daz,

Soundcard = Realtek (Speaker + Headset)
After rendering in Delivery the audio is also bad.

The file in DV is Audio and Video .mts

If i rendering the audio fili to mp4, all is ok.

Most probably the AC3 audio in the file I guess.

i tryed a new clip with Stereo
Now in the timeline the audio file is a straight line and with no sound.
if i played the cilp in the vlc player, all is ok.
It´s terrible
