This bug has been there since the first releases of Teamspeak 6, making it unusable for those in a noisy environment.
The toggle in settings → audio → audio processing → Echo Cancellation
Can be enabled, but as soon as any other settings menu is selected, like account or identities, instead of audio settings, then it gets turned off.
This is very annoying, running Teamspeak6 as admin does not fix this bug.
Please fix.
