Ever since I downloaded Synapse 4, I have been plagued with the following problems:While mic monitoring is enabled, I can hear a faint echo of myself on a delay, on top of the existing intentional side tone. This means I hear myself twice, once the normal way, and again shortly after and quieter. It sounds like the “Listen to this device” feature in Windows input settings. While mic monitoring is enabled, my output volume is lowered to about half of its output. However, Windows and the Razer Synapse app say that its still at 100%. This makes everything super duper quiet.I have reinstalled Synapse SEVERAL times, going as far as getting more and more exhaustive with my removal methods. I first enlisted the official guide for reinstalling Synapse on Windows, but this did not resolve the issue. I downgraded to Synapse 3, and the issue was still occurring (Only the first issue, with the echo. The lower output volume does not exist after downgrading to Synapse 3). When this didn’t work, I uninstalled Synapse again using the guide above and used the official “Device Detection Troubleshoot Tool“ from Razer to remove the devices from Device Manager. I then used “pnputil” in command prompt to remove any leftover drivers that were still remaining from Razer and THX. This did not fix the issue, and upon reinstall of either Synapse 3 or 4, the issue was still present.As you can see, I’ve done a lot of troubleshooting. I’d also like to mention that there are many people with the exact same issue seen in this thread, all within the last 2 weeks.I am on Windows 11 Pro 23H2, OS Build 22631.4541. Synapse 4.0.86.2411140357. All latest available drivers and Windows updates installed. I don’t have 24H2 because Windows has not rolled it out to me yet.

Identical issue. Please address.
