If you are recording it is always a good idea to disable the automated channel notifications (member enters/leaves, etc.) so that they aren't heard in the recording. To do so, follow these steps:
- Click "Settings" at the top of TeamSpeak, then click "Options".
- Find "Notifications" at the very bottom of the list and click on it.
- Under "Sound Pack", choose "Sounds deactivated".
- Click "Ok".
- To re-enable, just follow these same steps, but select whichever sound pack you wish to use.
