Hi Xavier

If you can, please make a sample clip available.

Please take a look at the FAQ for details on OS, Resolve version, hardware, drivers you can include in your report. Do note that AC3 is not supported in Linux.

Regards
Shrinivas

I tried again.

The clip is listed as having 6 channels of AC3 audio, but the meters don't show any signal in Resolve.

The clip plays audio outside of Resolve, so there's definitely signal there.

Studio 17.1.1 for Windows.

Try this.

Open an administrator command prompt. You should be at C:\Windows\System32

Type: regsvr32.exe mpg2splt.ax

This should re-register the AC3 directshow filter.

Did the command say that registering was successful, or some other message?

Have you tried setting the Resolve audio preferences to "manual" and selecting your output device?

I already put in manual, but everything remains the same ... is there a way to remove the update without losing the database? thankyou

made a new database and now I can see waveform, but it is not heard, the audio of other videos is heard, the ac3 does not.
