Bluetooth Headset cannot be used as both headphones and speakers

It's absurd that microsoft still has to find a solution and correct this.

I had this issue. TLDR I fixed it by going to Services and running the Bluetooth Audio Gateway service. For some reason it wasn't running. I set it to "Automatic" now I can use them as a headset (input and output) on Zoom/skype etc. on W10.

The apps auto-select AG hands-free mode on the headset which is discernably lower audio quality than a wired pair, but for conference calls it works great and the important thing is that the MIC in the headset works in tandem with full stability.

I spent hours and hours researching this on this forum and others - didn't see this simple advice anywhere. Obviously drivers and sound settings are important to have right but the above trick did it for me in the end.

Created this account to share. Hope it helps, couldn't advise beyond this so sorry if it doesn't work for you. I'd start by researching above mentioned service and follow the breadcrumbs.

There is no "Microsoft deals with it".

This is how Bluetooth is supposed to work.

Bluetooth eco-system is about ten of thousands of different bluetooth devices from ten of thousands of different manufacturers working seamlessly together --- without specialized hardware and software.

If you need to buy an iPhone and a pair of AirPods in order for them to work seamlessly --- that's not really Bluetooth at all --- if the same AirPods don't work seamlessly with android phones or pc computers or your car...

If you need to run an app (like Bose app) on the phone to work with Bose bluetooth headsets --- then again that's not really Bluetooth at all.

I have a bluetooth headset that does not allow me to use it as both a microphone and a headset.

I have determined that audio will play through the Bluetooth headset as long as the recording device is set to Conexant ISST Audio.  If I set the recording device to BHS-530 Hands-Free then no sound will play through either BHS-530 Playback device.

I can get audio to play while the BHS-530 Handsfree is setup as the Recording device but not while it is actively listening.  As an example my BHS-530 Stereo is selected for both my default audio and default communication device.  I start playing a YouTube video and audio works with the Playback menu is up in the Sound dialog (first screenshot), as soon as I select the recording menu (second screenshot) the audio stops.  If I switch the recording device back to Conexant ISST Audio the youtube video will continue to send sound regardless of which menu I am on.

What do I need to set so that I can use the headset for both audio and microphone (Microsoft Teams Calls)

The headset comes up as two separate devices once it connects to windows:

Playback Device

Type: Headset

Name: BHS-530 Hands-Free

and

Type: Headphones

Name: BHS-530 Stereo

Recording Device

Type: Headset

Name: BHS-530 Hands-Free

Type: Internal Microphone

Name: Conexant ISST Audio

(this is my laptop's internal mic)

Aww, Thanks i was same thinking about it.
