Bluetooth drivers are crashing after opening "sound" ( sound devices) in windows 7 x64 or soundcheck from Avaya scopia meeting client This is happening with 300wx and ergo. WIth another Manufacturer device (Jabra), there is no problem What I made. I made complete windows reinstallation, but the problem is still the same. Other USB Bluetooth device - the some attached you can find the error message by opening the sound settings The Bluetooth devices are from Broadcom.


Broadcom Bluetooth it detecting the 55wx like STEREO Headset device, I changed the settings to MONO and now is working OK.

The ego model I detected like STEREO Headphones, unfortunately, the MONO settings are not helping here

Intel – autodetect like mono and is working stable, without any other settings
