There are actually people who treat emails and messages with a bit of privacy. Especially when it comes to accessing files.
But well, I can already see that in 5 minutes I will be a liar, since you are the second person in a few minutes....
Another possibility would have been to write to support and ask about it (you heard about a working update), or to wait a few days for the rollout.
So, that's the link which i've recieved 1 day ago via email:
RazerSurroundInstaller2.0.29.20.exe - Don't be surprised if you find older files with the same name in your dl folder... Had 3 of them with the exact same name.
I didn't uninstall anything before, just closed the app and started the installer, which ended almost immediately with the message that everything was updated. The day before I had tested it again with the old version - Got crackling sound. Now it's clean and works again.
And yeah, we are talking about the Razer Surround Pro app, what's a part of Razer Synapse.
Message to the mod: If external links to exe files aren't allowed, please be so kindly and delete the link without a warning/report. Would be a shame for this old user account.
