Short description
We're having problems with headphone input/output. We found a little activity that tests input/output so I guess it's meant to be posted here to find a solution. Are they self explanatory or more data is needed?

We're having problems with headphone input/output.

Do you mean headphone plugging and unplugging? Or audio input/output through headphones?

For the Nokia device, all of the failures were for INPUT open.
Either another app is using the microphone and blocking the test,
or OboeTester does not have RECORD permission.
I see that I am not asking for Permission in that test.
Try the TEST INPUT Activity to see if it can open a mic. It should ask for permission.
Or go to the launcher and long press on the OboeTester icon. Then tap App Info.
Then Permissions, and turn on Microphone permission.

The Huawei device looks like it has hit a known bug with plugin detection. More information here:

Thanks for the report. I added the Huawei device to the table.
