Question / Help Audio desync using 'source timing' sync method for NDI

[1L1dan]

Hi everybody!
I'm using 2 PC setup with the following config.
As a gaming PC I have the following:

CPU-i9-9900K
GPU-RTX 2070
RAM-32 Gb 3100 MHz
MB-ASUS PRIME Z370-PII
2x144hz displays

As a streaming PC I have:

CPU-AMD Ryzen 7 3800X
GPU-RTX 2060
RAM-16 Gb 3133 MHz
MB-MSI B450 Gaming Plus MAX
1x60hz display

To configure LAN I use TP-Link TL-SG1008D. Task manager shows 140 MB/s usage when streaming.

My gaming PC OBS setting are:

General:
1
2

Output:
1
2

Video:
1

Advanced:
1
2

My Streaming PC OBS settings are:

General:
1
2

Output:

1
2

Video:

1

Advanced:

1
2


And NDI sources settings on Streaming PC:

1
2
3
4
5

I use multiple(4) audio NDI sources to separate audio tracks for recording.

The issue is that there is a sound desync when using the latest plugin version for OBS. VOD for example:

Logs for streaming and gaming PC attached.

UPD. I used 'internal' method before, and the sound was synchronised

UPD. As audio devices in OBS on the gaming PC I use virtual cables.
