So I bought and use a XR1 Lite to capture MiSTer FPGA gaming footage. MiSTer is basically a small form computer that emulates retro gaming systems on a hardware level. I natively outputs HDMI and analog signals and can be set for a ton of resolutions and scaling options.
I have my mister set to output 1080p and in OBS have my base canvas and output set to 1080p, when capturing mister the video quality looks fantastic and audio is fine but while im capturing if I switch systems (cores) while capturing it introduces an audio delay.
 
Example.... I fire up MiSTer and OBS and start capturing a Nintendo game, If I switch to a Super Nintendo games it will add about a half of second of audio delay, If I then switch to another system and game it adds even more audio delay. The more I switch systems/games the more audio delay stacks and gets worse.
 
Ive been told avermedia and elgato users never experienced this problem.
At this point im not sure if its the XR1 Lite, Firmware, a windows setting, OBS, or what.
 
You can see an example of the issue on this video
 
 
Any suggestions?
 
EDIT+++ I have a video on youtube showing the issue but Im not allowed to post links

    This isn't something that we've test with so not sure what could cause this. We haven't had any issues with the current standard main stream consoles.

    I got this capture card 2 weeks ago and I noticed I'm experiencing this as well with standard main stream consoles. It really does not have anything to do with OP's device.
    I have not tested with the device mentioned here, but it's an issue I'm also experiencing with other streaming setups if you use an HDMI matrix or switch.
    My Nintendo Switch, PS5 and Wii U are all connected to one HDMI matrix that has a single HDMI out running into the capture card, when I switch consoles, it loses a signal for a brief moment and that's where it causes the video/audio desync. Allow me to elaborate:
     
    When XR1 Lite loses a signal, the capture card still keeps the audio capture intact, while it dropping the frames. This eventually will add up to a significant delay.
    I also have Blackmagic Intensity Pro and Elgato HD60S+, but they fix this problem by inserting blank frames. I heard some other capture card sends out "no signal" frame instead as well.
     
    My return window is ending soon and I was wondering if you guys could fix this via a firmware update?

    Generally speaking putting any device in between the xr1 and the video source can cause issues and it is strongly recommended to have the source plugged directly to the XR1 to avoid any issues.

    Appreciate the response, but I'm not quite satisfied that you dodged the main question regarding on the problem no other competing capture cards have as they add add blank frames for cases just like this.
    Even without any device between XR1 (Lite) and the video source, the original poster is clearly having issues without one as well.
     
    It does feel like a terrible oversight and lack of experience in the market seems to have contributed to this issue.
    Do you guys have any plans on fixing this problem via a firmware update?

    I've gone ahead forward this to our engineers to look into.
