Followed the sticky instructions: "How to configure audio for analog video capture devices" and have problems:
1. Audio output is only a rapid "put-put-put..." spaced less than 1 second apart, and goes to silence after less than 30 seconds.
2. Video distorts shortly thereafter.
Suggestions?
-
I re-read the sticky thread and found it quite out-dated.
To setup a video capture device like Colossus 2, you should create a "Capture only" channel in MC. You can either do this by running Setup wizard, or by going to Manage Channels tool and add a new "Capture only" channel.

Tried that with the same results.
-
Any suggestions? It still doesn't work.
-
Did you plug the audio video cables in correct connectors?
What general audio settings do you use in MC?
-
Cable is HDMI from Roku via splitter to HDMI in on Colossus 2.
Audio for TV: 48k, JRSS, 16 channels, no sub.
New "capture only" acts the same as "serial digital". Crossbar for both asks for AES Digital In, both produce the same noise and eventual degradation of video.
-
Maybe unrelated but try enabling time shifting on analog devices. That's what I need to do to get untouched bitstreamed Dolby Digital sound from my Colossus.
-
Tried time-shifting, but results remain the same. Other ideas?
-
Try removing the splitter and see if it works. Then in future, do all testing with the splitter removed until you get it working with a direct connection. Only then add the splitter back in.
However, is the source signal protected in some way, such as HDCP? I expect it would be, since AES is being asked for. Plus Roku is unlikely to be allowed to allow HD Digital signals to be output unless the full digital path is HDCP compliant. The symptoms you describe do suggest a deliberate degradation of the signal, consistent with HDCP, although usually you just get nothing through, or on a PC just get told the path isn't compliant.
So, is your full digital path HDCP compliant? That is one reason I suggested removing the splitter for testing. Maybe see if you can find a tool or method to test the digital path is HDCP compliant, or check with Roku/Hauppauge.

The objective is to get DD+ audio into my PC based main system...the Netflix app appears to be plain old super-compressed DD whereas Roku will output DD+.
Monitor and projector are compliant, but I doubt the PC is. Copy protection may be the issue as it seems to work okay on "open" Roku channels. I'll see if I can find a test tool.
-
NVIDIA test tool says the system is compliant. Cyberlink says there is a non-compliant video port...so I disabled Intel on-board video but that didn't help.

That pretty much confirms you are down in the murky depths of DRM. A place I try not to visit if at all possible.
It could still just be a format issue, but unlikely. I suspect only Roku and/or Hauppauge can help you.
