Question / Help [LiveGamerHD][STREAMING-PC] Audio Desync after time

[shodan.twitch]

Hello fellow OBS Admins/User/Developer,


ive got a problem, that bothers me a while, tried fixing it on my backend - including Hardware/Software/Driver Issues, but non helped so far, my last hope's are you guys right now, because its driving me crazy.

of Course i used to search for similiar Topic's here and on the internet but non or less got a working solution for my setup in combination with streaming on Twitch.tv, as you can see later on in the settings i'm streaming in 1080p, im partnered so that should be no problem. Tried already scaling down to 720p and similiar. My Guess : OBS or Twitch so far, maybe anyone can spot a error / mistake on my side so far. Thanks.


Okay here we go:

Streaming PC:

CPU: i7 3770k @ 4,5 GHz
CPU-Kühler: Thermaltake SpinQ VT
MOBO: ASRock Fatal1ty P67
NT: Thermaltake Berlin 630W
RAM: 16GB - G.Skill RipJaws
GPU: MSI GTX 750ti - 2 GB
CAPTURE: Avermedia LiveGamer HD

OS: Windows 7 Ultimate x64 atm WINDOWS 10 for testing purpose only xD

Gaming PC:

CPU: i7 6700k @ 4,5 GHz
CPU-Kühler: be quiet! Dark Rock Advanced C1
MOBO: Asus MAXIMUS VIII RANGER Z170
OS: Windows 7 Ultimate x64
RAM: 2x Crucial DIMM 8GB DDR4-2666
GPU: Zotac GeForce GTX 970 AMP! Extreme Core Edition 4GB
OS: Windows 7 Ultimate x64


Streaming PC captures Gaming / Microphone Sound Signal via HDMI.

Everything is working fine, after <random> time broadcasting on Twitch my Sound gets behind the video, which makes it desync, very annoying, the only thing to sync it again is to uncheck/check the LiveGamerHD Source everytime it desync, around random 20 minuter or so.

Okay - Settings:

Capture Card - LiveGamerHD - newest Driver

OBS - Encoding - btw im partnered so no problems there with Bitrate

OBS - Video Settings

OBS - careful - some "custom" Encoder Settings

Ok. Log File attached, as u can see in the Log every 30 minutes im going to refresh the LivegamerHD alias

this streaming session was with No Buffering enabled but made no change, since then i got buffering enabled.


Ok let me know if you guys need anything, i wanna get rid of this problem at all and maybe we can help some people out there which have similiar or the same issue.


Thanks in advance

The standard fix for capture device audio/video desync is to turn on 'use buffering' in the capture device's Properties, and leave it set at 0 or 1ms. From the log file, it looks like this is disabled.

Also... all of your settings are stored in the logfile. No need for screenshots. :)

Put your scene buffering time back to 700ms under Settings > Advanced, 400 is an old default and can cause audio sync issues.

Add your capture card as a global source if you plan to switch to scenes where it isn't present and then back again.

cant add the Device as a global because its not that simple to reset the Capture Card Source then anymore.

will try to change the Scene Buffering Time, thank you!

Why are you needing to reset the capture card source so frequently?

because of the desync that happens, with the reset it is back to sync for around 30 minutes.

 

[Sapiens]

The two changes I provided should correct the desync.

 

[shodan.twitch]

didnt change anything, still audio gets desync while the stream is in one scene, changing nothing on the stream pc, it gets desync -.-
