Re: audio problems,desync ?
Make sure that you're specific about what exactly is desyncing with what, and what is coming before or after what. For example, "the LGP's audio and video is going out of sync, after about 25 minutes the audio comes a quarter of a second after the video" would be an ideal way of being specific about it. There are also other things like webcams, mics, and you need to be specific about what all you're trying to get in sync as well.
Also technically it really shouldn't happen for its own audio/video if "use buffering" is on because that option specifically times the audio exactly to the timing of the device.. though it's not impossible depending on how it outputs audio. Hm, I have also heard that resampling can sometimes cause issues with this - could you guys try try changing the audio sample rate in OBS' audio settings to match that of the device? or, if you're at 48khz for example, could you try 44.1khz and see if that changes anything?
