I'm hoping someone out there is a mitel guru and can help me figure out why Call audio will not play through the user's headphones (ear buds). This is a really strange one. I have verified that the earbuds and headphone jack are working outside of call audio, in fact if the earbuds are plugged in, you can even hear the phone ring through the headphones, but when the call is answered, the call audio will only play through the laptop speakers other things play through the earbuds fine. I have verified the headphones are selected as the default play back device. System is running Win-10 1909.
I have checked the sound settings and nothing seems to be out of place. I also tried disabling the main speakers to try to force all audio to the earbuds, but when I tried that as a solution, the audio did not play at all. I was thinking maybe it was a driver issue but testing on my own laptop has (different make model and audio driver) resulted in the same problem. Any Mitel gurus out there who know about this and how to resolve?
