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

sygnus21, you're a hero! You had the final step in the equation!

SOLUTION:

1. Wipe all bluetooth settings and drivers, unplug and re-plug the Iogear dongle, achieving a blank slate
2. Install the appropriate Windows 10 driver from Product Drivers, Firmware & Software - IOGEAR
3. Open Start, type "Device Manager" and open the first result
4. Under Bluetooth, right-click "Broadcom BCM20702 Bluetooth 4.0 USB Device" and left-click "Update Driver"
5. Select the automatic option in the new window.

Finish updating that driver, and you're good to go!

Apparently, one must have Iogear's GBU521 driver installed first before asking Windows 10 to update it. Quite a complex process if you ask me, certainly not plug-and-play at all!

My bluetooth devices are now working fine and dandy!

 

Windows 10 problem with USB DAC

I have a USB DAC (digital-to-analog converter) that allows me to play music through my speakers.

It has worked fine for a long while but recently it has started to abruptly stop working randomly (over 10 times per day).

I can get it to work again if I:

• Unplug the DAC from usb and immediately replug it in.
• Disable and them immediately enable the device in the windows "playback devices" window.

I have tried:

• Uninstalling and reinstalling Nvidia high definition sound drivers
• Disable USB selective suspend setting (this is a PC not a laptop).
• Troubleshoot sound problems

Any help would be greatly appreciated.

Edit: The device is this one:

EHP-O2D Miniature Desktop Headphone Amplifier with USB DAC - Sound Manual

It is plug and play and I have never installed drivers for it.

 

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.
