I finally had time to investigate the issue. It looks like that as of 11.5, the DesktopVideoHelper.service has to be running for the capture card to work properly.

I think that pulseaudio is using the snd_blackmagic_io module, therefore preventing it from being unloaded.

Updated to 10.8a2.

I sent him an email

fthiery, that worked like a charm.. question is; where is the maintainer..

It appears I was able to install using linux kernel 4.4-lts. During the install it complained about linux Kernel 4.7 Here is some additional information. ==> Continue installing decklink ?

yea, im curious whats the status as im getting similar errors

The software was updated on August 1st. Has the issue been solved?

@rstoye This is a problem with the decklink driver itself, and can only be fixed by blackmagic. I've already contacted the blackmagic development departement, so that they look into it.
