Tips and Troubleshooting
ISSUE: One way audio or no audio:
A common cause of this behavior is packet loss and delay.
Possible causes and fixes:
- Cable/FIOS modem need to rebooted on occasion and if possible reboot the device once every two week. If the problem persists contact your ISP, packet loss is not the norm.
- Laptop WiFi card cannot handle the throughput. Even though signal strength is strong, the WiFi card may not be processing the data fast enough. When choosing a laptop look for one with a dual-band WiFi card. If possible keep the laptop plugged into an outlet. As the battery on a laptop gets weaker it conserves energy thus affecting the WiFi card signal
- The laptop doesn’t have enough resources, not enough RAM or processing power impacts call quality because the VS Connect software relies on those resources
- Using unsupported headsets can cause poor or no audio issues. Analog headset, earbuds, etc are not recommended. Approved USB headsets should always be used. Most Windows operating system rely on RealTek for audio, if there is an issue after a recent Windows update it is most likely caused my RealTek driver incompatibility. Try rolling back the driver.
TIPS:
- Use an Ethernet cable when possible
- Only use approved headsets
- Make sure your device meets or exceeds the recommended specifications
- Periodically reboot ISP router on occasion
