Asus Maximus Hero Z690 - Audio Crosstalk

[Log!cal]

I was experiencing a similar problem with PC audio playing out on Discord. Turns out the issue was caused in the Realtek Audio Control config, under Device Advanced Settings there was an option selected "Tie up same type of input jacks, i.e. line-in or microphone, as an input device."

This setting was causing PC audio out to mix with the microphone input, contrary to expectations. Issue would happen even if I completely unplugged the microphone and had no other input devices plugged in. Disabling this setting resolved the issue, though I did have to readjust microphone boost afterward.

Hi Mouser

The setting for "Tie up same type of input jacks" is not available with the current audio driver and Realtek Audio Control Panel. Also the "Acoustic Echo Cancellation" setting is not available as some users with other motherboards have reported using this setting also removes the audio crosstalk.

Hi Log!cal,
Thank you for your reply.
May I double confirm when you replicate the issue in windows sound recorder, you connect only one headset and no speaker connecting for the sound output?
Could you please take a picture of your ram like this?

Thank you.

Hi Log!cal,
Do you enable Stereo Mix?

If yes, please disable it and then check discord and windows sound recorder again.
Thank you.

Hi Log!cal,
Thank you for your reply.
I'll consult our tech team more about this.

Hi Log!cal,
I'm afraid our tech team cannot reproduce the issue with the devices at hand.
Do you have the issue since first build and install windows?
or does it occur after use the pc for several days? Was any settings different before and after you have the issue?
May I have more information about your audio settings?
Could you please help to use other drive to reinstall windows(or back up your personal files and then reinstall windows) to see if the issue still there without any settings changed?
Thank you.

Hi STARRAIN

Sorry for late reply.
The issue has been there for me since i first built the PC. I have since had 2 other motherboards (both Asus z690 maximus hero) and 1 other CPU (another 12700k) and i have had the issue. The CPU was exchanged due to a single core getting 10c to 15c hotter than the other cores and hitting TDP. The motherboards were exchanged because of this audio issue and the second motherboard was exchanged due to coil whine. All 3 motherboards have had the issue with the audio crosstalk using front panel audio or the rear io panel audio.

I have stripped down the computer and rebuilt it 3 times now and reinstalled windows 11 about 5 times. Each time was a fresh new install. I have re routed the front panel audio cable separately from all other cables to the motherboard connector.

I have the issue with just the standard windows audio driver installed, the asus/realtek driver all versions including newest driver 2307, with and without sonic studio, with and without realtek/asus audio control panel and with and without Dolby Atmos and DTS.

The issue is there with 2 different headsets both with 2 3.5mm connectors from a 3 pole 3.5mm single connector. The issue is not there if i have the mic plugged into rear panel and headphones plugged into front panel and vice versa. The issue is also not there if i use a USB headset.

Hope this information helps to get to the bottom of this.

Regards

P.S It also may be worth noting that the headphone impedance sensing has always been around 300 ohms. My headset is a 65 ohm headset.
