microphone

[Patrick Dupre]

Hello,

I have a Dell Optiplex 7060
There is only one jack sound plug.
Dell says that I can use it as input or output.
Head phone works perfectly.
If I put a microphone, it is not recognized
I checked that the Audio input/output are enable.

Why?

Do I need to install something else?

Thanks

Usually when there's only one plug, it's a 4-pin jack.  In order to use 
a microphone, you either need to have a headset or a splitter cable. 
That's the only way that you will get the microphone signal to the right 
spot.

Actually, I tried by using this
kind of cable.
4 connectins on the input jack, and
2 "outputs": a green one for the headset, and a ping one for the microphone.

But it do es not work (only the headset works).

There are two completely incompatible ways that a 4 pole 3.5 mm TRRS
jack can be used to carry combined headphone and microphone wiring.

Starting from the tip end it could be:

left, right, common ground, microphone (CTIA/Apple/most Android)

Or:

left, right, microphone, common ground (OMTP/Nokia/some Android/Sony)

Headsets with the opposite type needed for the socket might actually
get working audio in the earpieces, but not the microphone.

Since you're using an adaptor lead, you may have the opposite kind from
what you need.  If you can work out which one you have, try getting the
opposite.  If you can't work out what you have, you have two choices: 
Get someone else to determine it, or buy a pair of new adaptor leads
(one of each type).  But I'd suggest you try taking what you already
have (headset and and adaptors) to a mobile phone shop, or computer
shop, and see if they can help you.

     I think they  mean to be
used with headphone mic combo.
     if that is what you are trying to use. maybe the chipset works only 
with windows codecs and software
     probably a usb external sound adapter that works with linux would 
be required?

Patrick,

You can get some nice USB headsets that simply come with a USB plug
on the end, ready to go.  It works well here.

If you look closely at the male plugin on your Combo Headset, it has one 
more separator ring and hence four separate (electrically that is) metal 
contacts.  Pure headphones only have three.  I found this out only 
recently when I tried to extend my combo headset with a regular 3.5mm 
cable, it didn't work.  That is your issue ...
