Hello everyone!

Got quite a problem here.  I have a brand new XPS 13 7390 with Windows 10 (only about 3 months old) and I've run into a rather frustrating issue with audio.  Working from home, I am on Skype for Business and MS Teams calls all the time, often switching from one to the other back-to-back.  I have tried 3 different headsets now (Plantronics Backbeat FIT 305 - Bluetooth, Bose SoundSport - wired, and Solo Beats - wired) with the same results.  The Bose and Solo headsets are a few years old but the Plantronics is also only about 3 months old.

Randomly, the mic on each of these headsets will just stop working.  Usually this happens after a few calls and sometimes in the middle of a call.  I can hear the others on the call but they can't hear me.  If my laptop camera is on, they see me talking but no sound.  For the wired headsets, I just reseat the jack.  For the Bluetooth one, I have to power cycle it.  (Still shows to be paired and connected.)  In anticipation of a problem, I have reseated the jack or power cycled my Bluetooth headset before a call and do an audio check in either Teams or Skype before the call, but I still run into audio problems.

At this point, I'm fairly sure it's not a headset issue (unless I'm unlucky enough to have 3 bad ones altogether.)  I have run Windows Updates, I have run Dell Command Updates, I have run Dell SupportAssist, I have run the Dell diagnostics online, and I am current on drivers/updates and no issues were found.  I don't know what else to do or try.  I just know I can't be swapping headsets or (un)plugging jacks or power cycling headsets all day anymore.  Any insight/help would be greatly appreciated!!

Thank you kindly!
