Mouselag when muting or unmuting

[alphatonic]

Describe the bug I have a Corsair K70 MK2 Keyboard with dedicated Volume Wheel and Mute button. I bound the mute button to muting in Volume² to change the ugly default windows volume popup to something more pleasing. If i press the mute button my mouse lags for a second or two. Did something change with the latest version of Volume² to cause this?

Desktop (please complete the following information):

• Windows version: Windows 10 Pro 64Bit 21H2 Build 19044.1466
• Volume² version: 1.1.7.449

I cannot reproduce it on 2 my PC's

Maybe my sound-card is dying or the driver is bad. I'll try some things and report back.

I have the exact same problem for some time now, i'm not sure if it's a coincidence or not but i have a similar keyboard Corsair K70 LUX Cherry MX Brown.

My last PC was:

MB: Asus Z170-A CPU: I7-6700K GPU: MSI 1080

• Windows 10 Enterprise x64
• Volume² v1.1.6, build 428
• Volume² v1.1.7, build 449

My current PC is brand new with all new parts except for the SSD/HDD and fresh Windows install:

MB: MAG Z690 TOMAHAWK WIFI DDR4 CPU: I7-12700K

• Windows 11 Enterprise x64 22H2
• Volume² v1.1.7, build 449

In this example i'm constantly rotating the mouse to visualize the flow while pressing the mute/unmute button:

After hours of testing and searching i found out that:

1. I think the core problem seems to be Realtek audio drivers;
2. When i don't have any Realtek drivers installed Windows seems to auto install a driver called "Realtek USB 2.0" and when i press the mute button the volume gets muted/unmuted instantly;
3. If i install the latest "Realtek HD Universal Driver" which for me is version 6.3.9600.2342 i get a slight delay from pressing the mute button to the volume actually getting muted/unmuted (with Volume2 CLOSED) but i don't get any mouse lag; I also found this article with someone having the same issue.
4. If i do the step above with Volume2 open i get really bad mouse lag, only when muting/unmuting but NOT when changing the volume which is ok;
5. Starting Volume2 as admin doesn't seem to change anything;
6. I also tested a fresh Volume2 install in Windows sandbox with my same "Config.ini" and i can't reproduce the lag which makes me think this is caused by Realtek, Volume2 just adds the lag.

With everything i tried the only solution seems to be not installing any Realtek HD Universal Drivers but that potentially could lead to other audio problems.

Very interesting discovery but without the Realtek drivers my 5.1 setup doesn't work as intended. I now stopped using mute and just lower the volume to zero when i want to mute audio.
