Windows 10: Bluetooth speakers and headphones connect but don't show in 'Volume' or Sound settings

Hi everyone :I've recently discovered that my Bluetooth soundbar and headphones connect but don't show in 'Volume' or Sound settings. The strange thing is that a different set of Bluetooth speakers show up everytime, no problem. I've run the troubleshooters for audio and Bluetooth with no luck, I've removed the devices and updated drivers in Device Manager, changed Startup type to automatic in Bluetooth audio gateway services and Bluetooth support services. However, under Services and Bluetooth User Support Service_1057 I can't change teh startup type as It says 'That parameter is wrong' when

Iogear GBU521 Bluetooth Don. - Not Headphone Compatible on Windows 10?

Windows 10 version 1903


Short story: Our Iogear GBU521 Bluetooth Dongle was used on a different PC running Windows 7 to connect headphones with good-quality sound. Now, on a Dell Inspiron 580 with Windows 10, we can't get the headphones to work with the same quality anymore.

Depth: All Windows drivers are downloadable on this page of Iogear's website: Product Drivers, Firmware & Software - IOGEAR
However, it appears as though the Windows 8/8.1/10 driver is really designed for 8 and 8.1 and not 10. That I conclude because the file name, "GBU521_GBU421_Win8_Win8.1_BT_v12.0.0.9980.zip", does not mention Windows 10, thus suggesting my bluetooth audio problems to be originating from a driver compatibility issue.

I've fiddled my life away with the following:

• WinKey+R / "control panel" / Devices and Printer / (Insert Headphone Name) Properties / Services
• Start / Settings / Devices / Audio
• Start / Settings / System / Sound / Output / Troubleshoot
• Settings within the Iogear bluetooth devices program, which comes with the driver on the aforementioned driver page.

And have gone through many settings that branch off this list, restarting the computer after each change made. Sometimes it connect with good sound quality, but does not retain this quality after breaking the bluetooth connection (turning the headphones off, restarting PC).

Quick side note: I have a new Microsoft Bluetooth 3600 Mouse connected to this dongle that works completely fine, unlike the headphones.

A solution requires the following results, which goes along the lines of how the bluetooth headphones were connected to this same Iogear dongle on the different PC that had Windows 7:

• The bluetooth headphones play with decent quality
• The volume retains it's setting whenever the bluetooth connection is broken by a PC restart, or powering off/on the headphones (I've encountered configurations where the headphones always resets to maximum volume).
• The bluetooth mouse works fine. This shouldn't be much of a concern at all.

If we find no solutions, I will simply buy a dongle that works with Windows 10.

I can provide screenshots if needed.
Thank-you.

 

Bluetooth headphone sound volume keeps changing.

I have a relatively new Bluetooth Pulse Echo headphone set and an Acer Aspire 3 notebook that has Windows 10 O/S. When I use the headphones with the notebook in wireless mode the sound volume alternates between normal and very low. I have run Windows Bluetooth fault finder and disabled sound enhancements to no effect. The headphones work fine in conjunction with my iPad however.
Could anyone suggest a solution for this problem please?

 

Different application sounds coming out from speaker and bluetooth

Only Adobe Rush through speakers. The rest will be through the headphones when bluetooth is connected. When not connected, it goes through speaker.
