Thanks Lawrence for the reply, appreciate it. I'm completely new to video/audio editing, I did spend 10-15 minutes looking through the log before posting, but wasn't sure what I was looking for other than 'audio' and 'error'.
There are two devices that I'm not using for my Stream, Desktop Audio and Mic/Aux. So I have muted them. I can see I can 'hide' them from the audio mixer, but I don't think I can remove them, I assumed 'hide' is purely cosmetic:
I haven't played with any audio settings here:
I can see the two different rates you've mentioned for the audio in the log; 48000 and 44100. I'm not sure where I can amend them, other than the overall sample rate in the above image which is set to 48kHz.
My PC isn't wifi enabled, it's 100% ethernet I'm quite picky on using ethernet for all devices, so I'm not sure what this is in the log;
Qualcomm Atheros QCA9377 Wireless Network Adapter #2 (802.11, 108 mbps)
The only two devices I require sound for is Elgato HD and xsplit Cam, and they are both set to Monitor and Output.
If you think any other screenshots may be of any use, let me know. If there are any general settings you would recommend, that would be great.
I have streamed this evening for around 3 hours, with no audio issues. The only thing I changed from last night was OBS being run as Admin, could be a coincidence. Had a scan through the latest log, and the sample rates are still 44100 and 48000, and that wireless device is not mentioned.
Again, thanks.
