AverMedia Live Gamer Mini has good quality output through RECentral but not through OBS. I am using the GC311 on my MacBook Pro, when using RECentral I get smooth gameplay recordings and streaming. I tried using it with OBS and SLOBS, and I get very bad quality in terms of recording and streaming. Mac system requirement: Operating system: MacOS High Sierra 10.13 Mac Thunderbolt 3 (USB‑C) Cable (0.8 m).

Live Gamer ULTRA
The next generation of game capture is here. The Live Gamer ULTRA (LGU) brings 4K capture to the table while its pass-through allows gamers to fully experience what 4K HDR is all about. Not limited to 4K HDR, this compact device can pass-through high refresh rates of up to 240 Hz on a full HD signal as well. Ultra, indeed.
4K High Dynamic Range Pass-through
Don’t give up 4K HDR content just to be able to record your gameplay. With 100% lag-free, 4Kp60 HDR video pass-through, the LGU allows you to enjoy mesmerizing 4K HDR gameplay and record at 4Kp30!
High Frame Rate Capture
With its high frame rate capture ability of up to 120 fps for full HD signals, the LGU is the first external game capture device in the market to bring super smooth recordings to your archives.
Easiest Setup Ever
The LGU takes full advantage of UVC technology, which basically standardizes video drivers across Windows and Mac. In other words, all you need to do is plug your LGU to your PC or Mac, and it’s ready to record and stream.
RECentral—Powerful Streaming Software
First in its class! RECentral is the first gaming capture software able to record HDR content. And it doesn’t stop there, RECentral is also able to simultaneously stream to multiple platforms such as Twitch, Youtube, Mixer, and more.
Customizable resolution utility
If you decided not to connect a display to the HDMI output (pass-through) of your LGU, we got you covered! With the AVerMedia Gaming Utility, you can customize which resolutions and corresponding frame rates you are able to preview and record without the need to connect a pass-through monitor.
Capture, Record, Edit 4K
Are you thinking about editing your 4K videos? This is a good starting point: The bundled CyberLink® PowerDirector™ 15 is a feature-packed, intuitive 4K video editor to kickstart your editing skills.
When I'm capturing audio from my Avermedia Live Gamer Ultra GC533, I get these occasional audio sizzles/fry, small pops, and stutters. Here's my setup:MacBook Pro (15-inch, 2018)
2.9 GHz Intel Core i9
32 GB 2400 MHz DDR4
Radeon Pro 560X 4096 MB
Intel UHD Graphics 630 1536 MB
MacOS Mojave Version 10.14.2
Here's a list of everything connected to the MacBook Pro:
Xbox One X > GC553 > Apple Thunderbolt 3 USB-C Cable > MacBookPro
Mixamp Pro TR > Focusrite Scarlett 2i2 > USB Cable > CalDigit TS3Plus Hub > Apple Thunderbolt 3 USB-C Cable > MacBookPro
Logitech C922 Camera > USB Cable > CalDigit TS3Plus Hub > Apple Thunderbolt 3 USB-C Cable > MacBookPro
ElGato StreamDeck > USB Cable > CalDigit TS3Plus Hub > Apple Thunderbolt 3 USB-C Cable > MacBookPro
Here's an example of the sizzling/popping sound, coming through on a twitch recording:
https://www.twitch.tv/videos/346111640
This happens when I create a source for Audio Input Capture and set the device to the GC553. In the mixer, if I raise or lower the volume for this source, the sizzle/fry sound raises and lowers on that channel.
I was even able to reproduce the issue on a different MacBook Pro using the same setup.
I managed to figure out a workaround by deleting the Audio Input Capture via the GC553 and capturing the game audio through the Mixamp Pro TR. It works but my game audio, chat, and chat mic all come through the same channel and I'd like to be able to adjust the channels through OBS.
I contacted Apple support (got upgraded to Tier 2, went back and forth with their engineers) and this was their final verdict:
The logging is indicating that a USB audio device is ‘falling behind’ meaning that its clock is not in sync with the master clock and the sample rate is going out of sync, creating the distortion they are hearing.
This is indicated as such:
2018-12-14 09:25:44.030919 -0800 kernel USB Sound assertion (Input Fell Behind) in /BuildRoot/Library/Caches/com.apple.xbs/Sources/AppleUSBAudio/AppleUSBAudio-315.6/AppleUSBAudioDevice.cpp at line 6502
The reference to the basic Apple USB Audio driver indicates that the device is a class compliant device, but as most USB Audio devices are, or can be, sadly that doesn’t help narrow down which is specifically having the issue.
However, right off the bat, we can see that their Live Gamer Ultra-Audio, CalDigit devices, and their Scarlett 2i2 are set to different sample rates.
Live Gamer Ultra-Audio:
Input Channels: 2
Manufacturer: AVerMedia
Current SampleRate: 48000
Transport: USB
Input Source: Default
CalDigit Thunderbolt 3 Audio:
Manufacturer: CalDigit, Inc.
Output Channels: 2
Current SampleRate: 48000
Transport: USB
Output Source: Speaker
CalDigit Thunderbolt 3 Audio:
Input Channels: 2
Manufacturer: CalDigit, Inc.
Current SampleRate: 48000
Transport: USB
Input Source: Default
Scarlett 2i2 USB:
Default Input Device: Yes
Input Channels: 2
Manufacturer: Focusrite
Output Channels: 2
Current SampleRate: 44100
Transport: USB
Input Source: Default
Output Source: Default
The system is reporting (as seen above) that the AVermedia and CalDigit devices are set to 48kHz and the Scarlett is set to 44.1kHz. If these devices are both being used by the same app, or are configured as an ‘aggregate’ audio device with themselves or another device, then there will be unmatched sample rates that will lead to issues like the customer is describing. And there is an aggregate showing in their configuration that is set to 48kHz sample rate as seen below.
Aggregate Device:
Input Channels: 6
Manufacturer: Apple Inc.
Output Channels: 2
Current SampleRate: 48000
Transport: Unknown
Input Source: Default
Output Source: Default
We would suggest that the customer set their Scarlett 2i2 to a 48kHz sample/clock rate and assure that all devices are in a class compliant mode to assure they are all using nonconflicting standard USB audio drivers.
They’ll also want to make sure they have the most current firmware for their particular devices, especially the AVermedia and Scarlett as they both would be the most ‘involved’ in creating an issue like this.
Outside of that, the customer will want to continue working with both the developer of OBS (for configuration assistance with the app itself an its sample rate settings, etc.) and the manufacturers of their other devices (CalDigit, AVermedia and Focusrite).
The good news, is that this is related to one of the USB audio devices, or simply its configuration, not the computer itself.
So as to not interrupt their current install, they may want to create a new test partition on their internal HDD and install a clean installation of macOS Mojave and setup the devices and test various configurations there. Then, once they find the culprit (be that a simple configuration issue, firmware issue, or even having an issue with the HW on one of the USB devices noted) they can isolate it and go back to their main install and adjust the changes there.
Though we can’t 100% resolve this one for the since it is pointing to one of the USB devices (or its configuration) as the source of the issue, I do hope this helps them get back up and running and configured correctly, or helps them locate which piece of USB audio hardware is causing the conflict
CalDigit Thunderbolt 3 Audio 1 Output > Format: 2 ch 16 bit integer 48.0khz
CalDigit Thunderbolt 3 Audio 2 Input > Format: 2ch 16 bit integer 48.0khz
Avermedia Live Gamer 4k Hdr Capture Card
Live Gamer Ultra-Audio > Format: 2ch 16 bit integer 48khzBut these two... this was as close as I could get:
Scarlett 2i2 USB > Format: 2ch 24-bit integer 48.0khz
C922 Pro Stream Webcam > 2ch 16-bit integer 32khz
I can't change the bit depth on the Scarlett 2i2, and I can't change the sample rate on the C922 Webcam to anything higher than 32khz. Could this really be the problem? I'm not even capturing audio from the webcam but I recognize how it might be a problem. Do I need to get a new mixer or a fancier webcam? Or are some of my settings in OBS just off or wrong?

And the weird thing is if I remove the Live Gamer Ultra as the audio capture source for game audio and capture the audio through the mixamp pro tr > Scarlett, I don't hear any pops.Avermedia Live Gamer Ultra Driver
I'm pulling my hair out over here. Any ideas?
