Hi @Gore, Sharon : BUK Customer Care UK
Could you please clarify which application you're using to receive customer calls?
First, check if your headset is working correctly by playing a video or any other audio on your computer.
If you can hear the audio, the issue is probably related to the application you're using for calls, open Settings > System > Sound and make sure your headset is selected as the default output device
Also, open Volume Mixer and check that the calling application is not muted and is using the correct audio output
If everything looks fine, try disconnecting and reconnecting your headset, then restart the application
Also, can the customer hear you, or is the audio not working in both directions?
Let us know
