quiet confort II audio (bluetooth or wired) stopped working, help
Hi , My QC 35B II stopped working suddently while I was listening to audio via wired connection. The audio and the noise cancelling went off. Lights are OK, recharging works.
First tried to switch off, then on multiple times.
Then reset my headset (30sec off, plugged 5 sec to power and wait 1min, switch on again).
I then tried via bluetooth (my phone and my computer had the bluetooth connection OK with the headset): no sound.
I then tried to upgrade the firmware; it appears that I had the firmware 3.1.8 and upgraded to 4.3.6 with my computer. The upgrade went OK.
Still the same problem.
The only way to have audio is to switch off connect by wire: of course this passive mode works. When I switch on, no audio.
I tried to dowgrade using advanced mode (a d v up and down arrows) but I only have the latest firmware available: 4.3.6, not the old ones. here is the system information in advanced mode:
