audio issue going through Blackmagic

[Sheeba]

Any help appreciated.......Not sure if this is the right part of forum to post this but....

I have started experiencing crackling popping sounds from my audio output device (Blackmagic Shuttle USB). Currently Edius is using the Blackmagic device to output both audio and video through HDMI.


I would like to continue montoring video with HDMI but would like to change the audio monitoring device to be my PC's onboard output (Realtek Audio device).

How can I configure Edius to output my audio/video output to these 2 different devices?

If the Black magic has RCA audio outputs, you could loop them to your soundcard input via stereo RCA to stereo mini jack cable

but be warned that lip sync will not be perfect because HDMI video may be delayed to analog audio (maybe out by 1 or 2 frames)

Thanks for reply Anton....
I think I'm trying to bypass blackmagic completely, because blackmagic seems to be causing the crackling problem. (and updating blackmagic drivers didn't solve it.)
My tech guy is the one who asked me to query on the forum about this issue. He has looked through Edius settings and was surprised he could not find any audio settings that bypass blackmagic completely?

I have 0 issues with the PCIe versions of BM cards

you may hear crackling sound if you run out of buffer because of heavy layering or many filters

do you hear the crackling with full buffer playback?

I have a Shuttle from the first year of release.
Mine is running on 9.54 and an X58 chipset.
The X58 chipset is what it was designed to run on.

Did you try a different cable, different USB port or even a complete uninstall of not hardware and software and reboot?
Then a reinstall?

Edius does not let you send the audio and video to different devices. I presume that this is done to eliminate the sync delay that Anton mentioned. If you are not hearing any issues from the analog outputs of the shuttle, I would suggest you try to use a new HDMI cable as a test or even a different video monitor to see where the problem actually resides.
