I found this old thread
I have an Intel AC 7260 but followed the steps to try to rectify the poor audio and nothing changes.
I have updated the Bluetooth drivers. I have turned off the telephone option from the headsets, but the audio quality is poor. It is fine when connecting to my mobile phone so it's not the headset in terms of handling the quality.
I found the other thread but was not able to get the answer.
We understand you're experiencing poor audio quality when streaming to your Bluetooth* headset.
In order to better assist you, we would like to have some more information:
- What is the brand and model of your Bluetooth* headset?
- Was your audio quality always bad when streaming from this computer, or did the issue begin recently?
- We understand that when you use your mobile phone to stream audio to your headset, the quality is ok, correct?
