Audio Distorted

[nalilord]

Hello,

the audio output of the DirectShow filter (OBS-Audio) is distorted after OBS is launched. To fix this stopping and starting the VirtualCam output again is necessary.

We tried switching the used sample rate between 44.1 and 48kHz in OBS, no change.
Also we are using and outputting the signal to a DeckLink SDI card, the SDI sound is fine.

We are using OBS 23.02 64 bit.
VirtualCam version is 2.0.3.
The application that uses the virtual sources is in 32 bit.
Everything runs under Windows 10 Pro 1809.

I guess the compatibility of directshow audio device may not as good as video parts since there's only few 3rd party software support it . For more researching , what's the software you are using to output signal to Decklink card ?

We are using the built in functionality from OBS to output to the decklink card.

I believe it's this: https://github.com/obsproject/obs-studio/tree/master/plugins/decklink
