Question / Help Resolving Audio Crackling via Elgato HD60 on Mac in Bootcamp

[wonderwez]

Hi folks, reaching out for help because I haven't been able to troubleshoot this myself. I have a bit of a kludgey setup which may be causing the issues, but not sure.

Streaming Computer: Macbook Pro with an Intel Core i7 2760QM CPU @ 2.4 GHz
Memory: 16GB
Operating System; Windows 10 in Bootcamp, 64-bit
Game Capture Device: Elgato HD60
Gaming Device: PS3 (running through an HDMI 1x2 splitter to counter DHCP)
Webcam: Logitech C920
Headphones: Sennheiser U320
Net speed: 29Mbps down (up to 50Mbps) // 6Mbps Up

---
OBS Settings:
Encoding: x264, Max bitrate: 2000
Audio Encoding: AAC, 48kHz, 128 bitrate, stereo
---

Here's the issue, when I use the Elgato software to preview my stream, there's no audio glitches and everything looks & sounds fine, but when I set it up in OBS, I hear crackling and intermittent glitches in the PS3 game audio preview (and playback when recording). I thought it might be an issue with the splitter, but since it plays fine in Elgato's software, I was wondering if I have something set wrong in OBS? Uploaded a latest log for your troubleshooting pleasure :)

Does it still happen if you create a new scene collection and add only the Elgato to it?

 

[wonderwez]

Yes, audio cut-out still present when I created a new scene with only the Elgato...

Could you give OBS Studio a try instead to see if it also happens there?

 

[wonderwez]

Trying now, but I'm a little less familiar with the menuing in Studio. Getting an audio delay...

Pretty sure I figured it out. I'm outputting the audio to my desktop, so enabling the "Use WaveOut audio renderer" appears to have corrected the issue!
