CasparCG slows down with Decklink cards on 1080p5994 #1191

Expected behaviour

CasparCG should work with no lag / slow down during broadcast.

Current behaviour

After running for 1hour and 15 minutes, CasparCG drastically slows down and all the templates start lagging. This only happens with decklink cards enabled in the config and on 1080p5994. It does not happen on 1080p6000.

Tried multiple windows installations, different CasparCG servers and different decklink drivers.

The issue also happens with one decklink card disabled and with no template running.

A temporary solution I found is to put <embedded-audio>false</embedded-audio> on both devices. This doesn't solve our problem though as we can't play videos with audio this way. So the issue definitely comes from the audio source. I wanted to check if I can modify any sound settings but it's locked to 48khz DVD Quality in Windows.
