I tried running through different switch options on my headset but on this quick check it didn't seem compatible. I wonder if UAL wired the mic plug with no mic voltage or if this was just a fluke? thx
This is an issue with some of the aircraft. I use a Bose A20 (carry over from the 737) and found that occasionally the mic plug didn't feel like it was fully seated when plugged in. When this happened, the mic portion of the headset wouldn't work.
The are at least two mic plugs that are common on commercial headsets. They look very similar but one has a slightly more rounded head. If you are using a personal headset and are having problems, this is probably the issue. Compare your mic jack plug to the stock setup on the aircraft. You'll probably see that your mic plug is slightly different.
If you are using a Bose aviation headset, call their aviation support number. They will send you an adapter that will fix this issue.
Hope this helps
