OBS Clocking/Lagging

Our instance of OBS clocks in certain situations. I think I have part of it narrowed down, but thought I'd post a log file for those with more knowledge to pinpoint things for me.

We're running a 1 y.o. laptop with Windows 10. The log file will provide the details on that. When we go to start our stream (at 9:05:36 in this log file) OBS hangs for 15-30s. I think it's having trouble with a browser based file/source in one of our scenes. We didn't have any other problems this morning that I can recall, though sometimes it hangs in other places. Our service ended at 10:07:11 and then I clicked around a few other places.

Thanks for any help you can provide for this issue or other items you may notice that we could clean up.

What i can see:
First things may get wrong here:

06:51:08.896: Livepro L1: data.GetDevice failed
06:51:08.896: Livepro L1: Video configuration failed

What is this above? A missed device?

06:51:10.853: [WASAPISource::WASAPISource] Device '{0.0.1.00000000}.{8a20a3c5-81e9-4990-80cc-ac0b776f2bc2}' not found. Waiting for device
06:51:10.897: [obs-ndi] started A/V threads for source 'FELCS-IMAC.LOCAL (StreamingLaptop)'
06:51:10.897: [obs-ndi] A/V thread for 'ProPresenter' started
06:51:10.923: [WASAPISource::WASAPISource] Device '{0.0.1.00000000}.{f2395509-5ab8-4dd5-b597-97c8ac476208}' not found. Waiting for device

Missing devices here, too. In between the init of a ndi source?

06:51:11.216: [WASAPISource::WASAPISource] Device '{0.0.1.00000000}.{65531f1c-4dc0-4078-91e5-d87a698d31d0}' not found. Waiting for device

Next device? (Another ID)
Then problems start long before stream start:

08:02:38.693: Max audio buffering reached!
08:02:38.693: adding 917 milliseconds of audio buffering, total audio buffering is now 960 milliseconds (source: Roland Audio)

All in all a very complicated and huge setup. Can you possible thin out the setup?
 
konsolenritter, Thanks for your anaylsis. I'll have to look into a couple of these.

I vaguely recall having the Livepro L1 in the loop some time ago, but we have a different switcher now, I thought.

The NDI/ProPresenter issue is related to our near-term switch to using ProPresenter 7 and sending lower thirds to our OBS machine, so that should resolve itself when we start using that in a couple weeks. I'll revisit to see if that's gone.

Yeah, the max audio buffering concerned me, too. I'll talk with our sound guy about that.
 
So what's your primary sound source at all? (possibly feeded by your venues mixing board?)
I'm afraid your sound guy couldn't help you on that, cause the audio buffering is collected cumulative on the digital side within your obs machine, whatever he sends on audio.
 
Your setup looks clean and nice!
So this sound comes over HDMI to/thru the Magewell Converter.

I think you aren't loosing much trying to restart with a fresh profile or scenes at all. Try to get rid of all that old stuff, dead links to former usb devices aso. And, if you can, try out a different converter just to be sure he isn't kidding OBS and you. =)

BTW: You can turn the browser hardware acceleration too, and in the windows system the gpu rescheduler. (Don't have that in mind where to switch, but there are threads here already regarding this.)

There was mention earlier of problems occurring before the stream starts. It takes a considerable amount of time for OBS to open up compared to our other site computer that has OBS. When I do scene editing, I almost always get a ‘program not responding’ as the added media/text/etc. I sit there and in about 19 seconds or so, it takes. When I select record or stream, OBS freezes, I get the ‘program not responding’ prompt and then it takes hold.
 
As said you should get rid of the old stuff, possibly starting from scratch with a fresh profile/scenes at all.
Add sources that really exist and look for the moment the issue raises again.

If the issue really is bound to the incoming audio from the Magewell converter, try to get the sound from the mixing board another way into obs, e.g. thru a dedicated audio device like steinberg ur-series, focusrite or the like.
