Five9 audio issues

If the headset doesn't work in Teams, fix that first.
- Check that Teams has the correct device selected.
  - If the device list doesn't change when you plug your headset in, the system may not be detecting the headset.
    - If the headset is USB, try plugging into a different port.
    - If the headset is a 3.5mm headphone jack plug, you may need to download and install the Dell MaxxAudio driver, and make sure it detects the headset as both speaker and microphone.
