Audio Issues with AverMedia Live Gamer 4k (OBS Specific)

After several months of struggling with a dying Elgato HD60S, I purchased an AverMedia Live Gamer 4k and it seems decent so far. However, I'm having two issues with it that are specific to OBS and seem primarily audio-focused:

1. Random, short audio drop-outs accompanied by a "pop" sound when audio returns. This is a Twitch highlight showcasing the issue twice in ~1.5 minutes (around 5 seconds into the video and 5 seconds before the end). I primarily speedrun and I can't have audio issues like this, cheating is a hot speedrun topic and audio inconsistencies sow potential doubt into my runs.

2. Audio desync (>1 second delay) and pitch change when changing consoles via my HDMI switch. This issue presents itself differently and the fix is slightly altered for my three consoles. On my RetroUSB AVS and Analogue Super NT the audio is delayed and the pitch is corrected, but I can fix it by simply opening the video input settings and immediately closing them again which appears to "refresh" the input. On my Nintendo Switch, the audio is sometimes delayed and the pitch is corrected, but I can't fix it via the same method as the AVS. I can, however, add the same source to another scene within OBS and it will not display these issues. Here is a short YouTube video demonstrating the pitch change and how it solves itself on my Switch if I change scenes (ignore the frame drop at the beginning, that seems to be a fluke and I did not see this happen in any other recorded videos yesterday). For my Switch, the only fix for the OBS scene I am actively using is to unplug the HDMI-IN and plug it back in - obviously not ideal.

I have confirmed that both of these issues appear to be specific to OBS as I cannot replicate either of them in AverMedia's RECentral software. Relevant log files are attached. Thank you in advance!

related to the pop and delay

you not read the manual? the encode adds a delay from audio and video feed
that needs to be added manual , the same linke on the elgato
thats a basic part of every record devices

a realy short quick search with google send me to this

your hole Post talks about that.
1. is the Pop thats a audio reset related to noth matching audio Frequenz or delay and its perfect show in your video reference
2. same here the pitch change is a result of the resync of the audio/video perfect seen in the video
that is a result of a Async audio/video or a async of the Sound frequence 41/48khz
bottom is a async its the hole time the same like the linked document in a range from 50-200ms so sometime not realy visible but shown in the reported issues

I'm sorry I don't fully understand your reply, but the pops are always present even when there is no audio desync. The pitch change and delay are not present until I change devices (or wait to turn on a console while OBS is already running). If I offset the delay the sound timing will no longer be correct a majority of the time. That also does not explain why the same source has audio delay and pitch shift in one scene but not in another.
