Complex Mixer Setup - Need an Audio wiz's help!

Many thanks for the help in advance!

My Home Audio setup has changed since my last post about splitting audio output on the PC, which I have solved by adding a sound card into the mix and this now does the job I needed.

System Info

PC Specs

Mixer: Behringer Xenyx QX1002USB
Sound Card: Creative Sound Blaster Audigy Fx
Microphone/Headphones: Audio Technica

Now onto the more complex part ...

Mixer Setup

AT2020 Microphone > XLR to XLR cable > Phantom Power Supply > XLR to 3.5mm cable > Sound Card Mic In > Adobe Audition > Sound Card Audio Out > 3.5mm to XLR cable > Mixer Line 1

PC System Audio > MOBO Rear Audio Out > 3.5mm to Twin 1/4" cable > Mixer Line 5/6

Playstation 4 System Audio > Optical Cable > Digital to Analogue Converter > Twin RCA to Twin RCA cable + 1/4" connectors > Mixer Line 3/4

iPhone System Audio > 3.5mm to Twin 1/4" cable > Mixer Line 9/10

Mixer Phones Socket > 1/4" connector + 3.5mm cable > ATH-M20X Headphones

Mixer Main Output > Twin 1/4" to 3.5mm cable > Sound Card Line In > Open Broadcaster Software

What Works

The microphone into the PC, being run through Adobe Audition, listened back to via Audio Repeater (MME) through the PC System Audio of the mixer - sounds perfect through the Mixer Phones Socket!

PC System Audio of the mixer - sounds perfect and does not pick up the microphone (no echo) through the Mixer Phones Socket!

Playstation 4 System Audio of the mixer - sounds perfect!

iPhone System Audio of the mixer - sounds perfect!

Problems

1a. The microphone audio from 'Sound Card Audio Out' is distorted when listening to it through the Mixer Phones Socket.

1b. The microphone audio from 'Sound Card Audio Out' is also distorted when recording a segment, after it has been piped through the Mixer and back into the PC and run through Open Broadcaster Software.

So, my question is ... How do I run this setup and not have the mic distorted after it has been run through the PC and back into the Mixer?

P.S. You can call me Matt.

P.S.S. I have been told to run the output through USB rather than the 1/4" Jack Main Out - audio for the jacks seems fine when recording a segment though.

You stated the mic audio sounds good and that it's distorted, both from the same output. So it would appear to be a mixer issue.

Distortion would lead me to believe you have a gain to high.

The microphone sounds OK when listening to it while it is still within the PC, after it has been processed by Adobe Audition.

When sending that audio out of the PC and to the mixer it distorts. It is not the Mixer, but the cabling that has been used. However, I cannot figure out what is wrong because I am not well versed with audio.

.

How are you listening to it "on the PC"? The OP states the exact same output.

It's not going to be a cable issue. Assuming what I noted above is wrong, the issue will be the part of the path that is different (very likely a software or hardware configuration issue).

I am listening to it back via the PC System Audio output, with the help of Audio Repeater (MME).
The distortion comes when the mic audio is sent back through the mixer from the SoundBlaster and into Mixer Line 1.

I'm sure there is a reason for the convoluted audio setup, in any case, assuming I understand correctly, then it sounds like the Sound Card output is too high for the mixer input. Reduce the sound card output (volume) or depending on the mixer, adjust the input level.
