DIY adapter to use your PC headset in your android :cyclops:

You will need

- 2 female TRS

- 1 male TRRS

- Wires! I strongly recommend USB wires

Ok just weld everything... yes is simple. But how :silly:? Take a look in the pics.

"The original TRRS configuration was created by Nokia and has a pinout", from TIP to SLEEVE, "of Left Audio, Right Audio, Mic, Ground".

=====================

DIY adapter to pass audio from PC or other hardware to your android with male-to-male audio cable :eek:

You will need

- 2 female TRS

- 1 male TRRS

- Wires! I strongly recommend USB wires

- Male-to-male audio cable

- Soundabout

Ok just weld everything, everything except the MM and Soundabout :eek:... yes is simple. But how :silly:? Just like the above but also look here first:

"Apple came along and in typical elitist fashion changed their pinout to", from TIP to SLEEVE, "Left Audio, Right Audio, Ground, Mic".

Then this adapter is exactly like the first above, but you will need change the Mic Right to Ground.

To force android to receive the input audio when you plug the male-to-male cable, you may use Soundabout.

Through this configuration you can send audio from any TRS output to your android, then the audio will be captured like a microphone.

=====================

The difference between both is only the MIC and GRND position in the TRRS male. They are switched. By mistake I switched and now I have 2 useful adapters.

FIRST OLD POST :

Hello knights.

My country are in such a chaos because of the manifest and I'm here mess around with technology... but I'm doing my part too xP.

Anyway, in the last days I was searching and testing a way to send the sound played in my computer, or other device, to my little android (codename Smultron).

With a 3.5mm cable (TRS or the one with 3 contacts) male to male, I plugged into the audio output of my Dell then plugged to my Mini, I started the app to record and... nothing.

Few days later, I used the app Soundabout and... nothing.

More few days later, I did the same thing BUT I don't put the cable until the end, I pulled out a bit, so the 3 contact of the cable stay full visible and... works! I was able do record the audio input of my laptop.

Also, with Soundabout, I was able to stream the audio from my computer to android calls!! For example, if you call me and I answer, if with the cable plugged I play some music on my PC the caller will clear hear what is playing in my computer.

In one more test, I used the MM cable and a splitter. With the Splitter and the cable I was able to stream audio from PC to android mic AND hear the android with a regular earphone, this test was made with a call in course, of course.

But this is only possible because in some way the PC are sending the signal with some extra power. If you try the test with a regular pc headset, without the computer this won't work.

"So why are you here if you did this you noob?" - Well I not figured out why or how the conectors are working when the stream are succesfully done. So I'm here to extend a bit this little research and ask for some help with who master this things. Also I wanna share with you all.

The keys of this are the jack conectors circuit and contacts combinations, and android audio routing using a app like Soundabout.

The main point, in other words, is how to made a DIY cable to stream audio from pc to android mic and with a splitter enable the audio output.

The reason that I'm searching for this is because initially I was looking for a way to did a DIY adapter for PC headphones with two jacks to android input, for single jack.

One more little thing, for the people that want to record a call without android modifications, you can plug the same male to male cable to PC MIC and start the sound record app of the Windows, for example.
