What are the best stable settings with minimal audio lag that you all have found? I've been struggling the past month or so with the audio skipping or cutting out on occasion since the latest OBS update

It's a long list, but short story is, if you set your Audio to "Unbuffered" (under AV), it should work (although you still get the occasional 1 second audio cuts and any new Stream will have static for a few seconds at the start) while losing slight game/network performance.
Also make sure to restart your OBS between games.
---
Long story: Every since AFTER OBS 27 (and that period of time with a specific revision of NDI + Windows + Nvidia updates related to WDDM), anything that "spikes" your PC usage from a "low state to maximum state" (mostly on weaker PC's I think) will start lagging the audio.
Please note nVidia is especially notorious for their Audio DPC Latency issues ever since the 1000GTX Series, and no one has tried to find a proper workaround (other than making your CPU and GPU no idle and always work at 25% power levels or P1/0 State).
For example (depending on Hardware and Drivers): Start OBS > Start Game = Audio Lag. HOWEVER, if you Start Game > Start OBS = No audio lag UNLESS the game does some fancy loading where they switch power states on you hardware (ei; old games like Deus Ex 2).
If game is hitting upper limits of your Hardware while doing extra work (ei; UE5 Game caching Shaders), you get Complete Audio Dsync at best, 3-9 seconds of cut audio at worst.
If Game has multiple options for Audio, try and switch them around before you start streaming or recording, since changing them Mid OBS usage will sometimes completely break the audio and requires restarting both OBS and the Game.
Some people reported setting Audios channels (both OBS and PC, as well Mic) to 44Khz instead of 48 Khz improved the Audio Lag issues (I personally saw no difference and it's placebo at best).
People with more expensive GPU (which have 2 Encoders) reported not having these issues compared to Mono-Encoder cards (like the x60 Series on nVidia).
Some people reported disabling the Intel Microcode related to Meltdown improved the issues (it improved performace for me, but not the Audio issues).
Some people reported Software for Mice and Keyboards (ei; ICUE) can be another source of issue. I can confirm that, but they're usually an issue for your entire PC and not only OBS (especially ASUS Crate).
Don't ask my collectively everyone decided to break stuff right around 2022.

Really odd. For some reason today I get random stutters every few seconds on the 2nd PC and I never did prior to that. I uninstalled both the NDI and DistroAV apps, and then manually made extra sure to delete their folders, then reinstalled. This is on Windows 11 for both machines.
Main specs:
-Gaming
5900x
32 gigs
RTX 3080
-Streaming
5700x
32 gigs
RTX 3060
GE800 is the router, which has all 2.5 and 10 gig ports. Running a fairly new firmware 1.2.1. I tried resetting the network settings in Windows, tried Framesync, etc.
I've been using this for years and only now is this happening. I wonder if it is some Windows update or some bug with the router's firmware, etc. I don't get it. I've tried re-adding the source after deleting it, etc. It will be smooth and then chug like it's dropping frames even though OBS does not report any dropped frames.
2nd PC settings - CBR/6000, 2 sec, fast, high, none
If I use a single pc to stream it's smooth as butter but I want to continue using the 2 pc setup I've had for years.
I wonder if it is a setting in the router? I have Flow Control turned off on the NICs, the router for WAN and LAN. I do not limit game capture fps.
? can anyone assist

Ran perfectly (besides minor audio blips) yesterday now I have the same issues as Jaybonaut. Did some windows/gpu driver updates and rolling back gpu driver updates did not fix the issue. (Using DDU, although not in safe mode)
Choosing "Lowest" for "Bandwidth" makes the source less of a slideshow but that's not what I'm looking to use. It's also still not the full 48fps I'm looking for. Tried restarting router multiple times and ran a bandwidth test for it, looks like very stable half gigabit per second.
edit: added info

~Half gigabit for reading, ~.9 gigabit for writing.
edit: Actually the "Lowest" bitrate setting does produce stable 48fps after double checking, was just the preview that looked off.
edit: Audio also looks stuttering from the preview with "highest" bitrate on the video btw. Changing framesync on/off, sync mode does nothing to alleviate the problem as well.

In Task Manager, my "Send" is stuck at average 50-70 Mbps (jumps around +-30%) when operating the software to send dynamic video output (and with static content as well), while using LAN Speed Test it goes up to 500 Mbps write 900Mbps read when interacting with a folder on the stream PC. (from the gaming PC)
edit: Minor additions. Also sending to a different OBS instance on the same PC seems to work without problem on both systems btw.
edit: Same issues when relaying video from stream PC to game PC. Although max Mbps sent is even lower.

Chiming in from the DistroAV team since these has been reported within the discord server. I normally test within Windows 10 with all updates being disabled to avoid any variables.
There has always been the knowledge of windows 11 messing things from time to time.. specially when OBS ran in the background and not as the focused window.
All of you with issues mind checking the latest windows updates and the windows build of your systems?
Reporting within the Github would be better yet we can't ask every user to do that. Once I have enough information I'll be creating a bug report.

Here you go. Let me know what else you need. OBS 31.1.2. Note that Tivvy is reporting the issue with Windows 10. I use all CPU encoding btw. Switching to NVENC shows the exact same issues. Must be a Windows network thing, has to be. Single PC is smooth as silk.

We are getting more information via this link:

Is there an existing issue for this? I have searched the existing issues and did not find a similar issue This bug exists on the latest available release of DistroAV and supported environment? I ha...

For the record, the runtime update does not address the issue as I had described.
As of right now, I need to remove two updates from Win11 23H2, KB5063878 and KB5063875. Removing '878 by itself isn't enough. If '875 is present, it must also be removed for current NDI (in the context of DistroAV) to work properly.

PSA to those affected by the recent regression introduced by Windows update : KB5063709 and KB5063878.
The recommended fix is to actively select the "single-TCP" or UDP, using the NDI Access Manager tool (tab Advanced).
Follow the "how-to" process by DistroAV
These update will keep re-installing and sometimes cannot be uninstalled
