Default Test your external microphone jack

I purchased 2 Nexus 7 tablets from Google and both appear to have the same manufacturing defect; if you insert a headphone/mic, the headphone works fine but the external mic does not. Perhaps a solder joint is bad in both receptacles. I wanted to use the tablet for Skype and SIP so I am returning both units.

Does the 3.5mm Jack even support microphone? Haven't been keeping up.

Yes, various posts as well as Google support have confirmed that it should work.

My N7 only has 1 channel coming out of the headphones. I tested the headphones and they definitely work. I don't have headphones that have a mic so I can't test if that works tho.

I have the same issue of the sound only coming out of 1 side on the headphones. I've tested multiple headphones on different units and it's the nexus 7 which I will be exchanging this coming Sunday.

I haven't had an issue with my headphones at all - crisp sound out of both ears. The microphone on the unit works as well (haven't had a chance to try out the wired ones). The only gripe I have about sound is that I wish the speakers were a bit louder, but a slight handcup on the back normally takes care of that!

Did you hear a loud click when you put your headphones in?

If not, ram it in HARD. It's seriously the tightest headphone jack I've ever seen...

Just to be (crystal) clear, it is the external mic input that is not working. The internal mic works fine. This may not be important to you if you never intend to use a headphone/mic. What is happening on my defective units is that the jack is not cutting out the internal mic and connecting the external mic so when you do a test make sure that the input is in fact coming from the external mic (tap on the external mic to be sure).

I don't think it supports the mic through the 3.5mm jack. I just tried a few headsets i have and none of them worked with the mic.
Where did you see any reference to the mix being enabled to the headphones jack?

Thanks.
