[Q] How do I record from an external audio source (Microphone/Line-In)

Hi, I hope you can help me out.
I'm trying to record some audio through the 2-in-1-combo-audio jack.
Everytime I connect an external music player to the transformer via audio jack, the transformer does not recognize that somethign is plugged in, but it thinks I want to use headphones (jack as output).
How can I swith to mic mode (jack as input)? Do I have to use a special asus app or is there a good app in the market that can do this?
Thx in Advance!

I doubt that you be able to do that

Why?
The specifications are very clear:
1 x 2-in-1 Audio Jack (Headphone/Mic-in)
Or do I understand this wrong?

I would guess that it will only recognize the microphone when it is connected via a 2 ring connector like a headset/mic combo. A mic by itself would not have a connection that the hardware could recognize.
I am only theorizing based on my experience with with an iPhone.

Hope you like mono recordings...

Maybe it can be achieved after 3.1 and with USB?

Yeah I think you are right, a member of another forum told me the same, that he plugged in an Apple Iphone Headset and the external mic on the headset worked. I also have such combo headsets with the same plug but they dont work. The internal mic still was still active. Could anyone please try to connect your headset and post if
1) the external mic will work
2) the internal mic gets deactivated.
3) and what headset is beeing used?
THX!

I will only use it to record voice, so thats ok.

Maybe then with additional Accessories, I hope to do this with the standard audio jack, which should be able to do that... at least according to the specs.

Quite possibly it would just need software to work. Since it is in the specs, a headphone/mic combination should work. I noticed tigerdirect was selling a combination headphone/mic as a bundle with the transformer.

You're going to want a 4 pin headset (mic/left/right/ground), which is how modern devices do dual input/output audio. Standard mics are 3 pins (L/R/Ground) just like normal headphones, therefore the hardware cant differentiate. Now the issue may come up on the arrangement of the headset pins. Prior to the iPhone, the standard 4 pin headset was configured in such a way that they would not work as normal headphones in devices that weren't meant to support headsets but Apple (or someone around that time) came along and switched up the order so that a 4 pin headset would be backwards compatible with a 3 pin jack -- a superior setup I say hesitantly, with the only con being that old headsets and new jacks are incompatible and new headphones with old (4 pin) jacks. If Asus is using the old standard, then an iPhone headset would not work and if Asus is using the new standard, then an old headset would not work.

Finally, it works!
I wanted to use an external audio source. You have to connect the cable first to the transformer, and AFTERWARDS connect the other side to the audio source. Only in this order the internal mic becomes deactivated.
If there is any signal on the cable while plugging it in into the Transformer, the internal mic is still active. I've attached my "cable construction".
The side with 4 pins goes into the transformer the 3 pins into a mono audio source (normal Headset Output). This works fine for me since I'm only recording voice (mono channel).
Problem solved!

[Q] What's missing between Apogee One > Nexus5?

[EDIT] When testing the setup below again it's obvious that the Nexus 5 doesn't detect an audio sorce. It does if I use the same cables connecting the headphone output on iPad Mini to the Nexus 5.
Hi
I need to be able to use Skype in my Nexus5 with an external, phantom powered microphone. It's powered by an Apogee One sound interface that has a headphone output with 30 Ohms impedance. I have the right adapter cables to connect the headphone output with the four pin input on the Nexus 5. But the quality of the sound heard in Skype is terrible. I guess the problem is the impedance. So please advice me on what I have to by and add between the two devices? Preferably something portable and not to expensive.

USB Type C to 3.5mm Headphone Jack Adapter

My issue
Hi everyone, I have a Nexus 6P and want to route my audio through a USB type C converter to 3.5mm headphone Jack. I have purchased one online, but it doesn't seem to be working. I have seen that the Moto Z has this adapter and I assumed one I found online would be compatible with my 6P. The reason I want to do this is because I prefer for the AUX jack to come out the bottom of my phone.
What I have tired
Changed 'Select USB Configuration' to all the different options and tried playing music.
Tried 'audio routing' apps from the app store
What I would like to know
Is this because I need to change a setting in my phone to route music out of the USB C?
Do I need to get some kind of DAC to allow support for this?
Has anyone else tried this with their phone?
Thanks

If you don't mind my asking, why bother?

One reason is that to me it makes more sense to put your phone upside down into you pocket. I've always done this at least. So when listening to music I have to put it the other way round. I have also heard the USB C port offers better sound quality.

Re:sound quality, you'd possibly see a quality increase if you use an external Digital to Analogue Converter or fully usb-c headphones. BUT, if you're using a little dongle (if it's possible), then the phone is still managing the analogue conversion and, thus, a very similar quality of audio output. Now I don't know of the 6p's ability to pipe it straight out iPhone 7 style through a dongle, but short of buying a DAC and going whole-hog on an audio upgrade, I'd just flip your phone the other way in your pocket and go the standard route.
Just my $.02

I have been looking for a solution to this too and I seem to have found one. I poked around on Amazon and I think I finally found adapters that work, here's the link https://goo.gl/QT2ith This the only one with positive reviews so when it comes in on the 30th I'll let all of you know.

Looks quite similar to the one that I got. Hopefully it works for you! Let me know how it goes

I read recently that the current implementation of audio over USB-C isn't very efficient or battery friendly. There's a new spec being ratified to provide audio like the iphone can. Hopefully that's a firmware change and not a hardware one.

I don't think it's possible on the 6P, not without using a USB DAC anyway.
As far as I'm aware, the adapter you have is for a USB 3/3.1 interface. While the 6P has USB-C it is USB 2.

I'm able to get audio out of my USB C port, but it's with a USB headset. Haven't tried it with a 3.5mm headphone adapter, but havd no reason to try it either.

This is weird. Because i have a pair of Sennheiser Urbanites (Wireless edition), and i can use bluetooth, aux, and usb (like for a computer) audio. I once tried to turn off the headsets (bluetooth off, aux and usb still works if connected), and turned off bluetooth on my phone. Then i used my USB type C to USB type A Female adapter (from the google store), and connected the usb-cable from the headsets into the type c adapter. it did output audio through the usb-cable.

Bluetooth headphones usually have their own DAC, so the audio for all but the Aux is still being sent through the DAC first, which is supported by older USB standards.
The new USB 3.1 Audio standard can pass through analogue audio from the internal DAC, which is what I believe phones such as the Moto Z utilise. Otherwise the adapter would require it's own DAC, which would make it far larger and more expensive.

Not sure if you will find a good solution at the moment since they just created a standard for audio over usb c http://www.businesswire.com/news/home/20160927006252/en/USB-IF-Announces-USB-Audio-Device-Class-3.0

Did the amazon converter end up working for you?

My experience so far.
Hi, I ordered some usb c to 3.5mm & out of the box so far they aren't working. I tried Neutron and tried to force the audio to usb but unsuccessfully with phone not recognizing the USB connection.
On the other hand the type C to usb-a adapter worked beautifully using mixplorer. If I get working, will update. Thanks.

USB C Audio Dongle

Hey all,
I got the Pixel 2 a few days ago and I love it, but there seems to be an issue with the audio dongle sound quality when connected to my car. Usually there's no problem with the dongle using it with headphones of any kind, but in the car (i checked the aux cable, no issues with it on other phones) there is some cracking sounds and the bass is not so clear as it is on other phones or as it is while using the dongle with headphones.
Anyone have an issue with the dongle?

Have you tried any other dongles? The Essential Phone had a higher quality USB C to 3.5 mm dongle compare to the Google dongle. I wish you can buy it. I saw this at Amazon https://www.amazon.com/gp/product/B0778QKKFJ/ref=ox_sc_act_title_1?smid=A1A7L2TLUUDQ97&psc=1 this might be better than the Google Dongle. I was going to try it to see. Anyone have any experience with this?

I haven't tried anything else, I just got the phone. But I unfortunately bought 3 dongles with it from Google to put on each of my auxiliary devices...

Ok I found out the problem while using the dongle on my brothers Pixel 1. The dongle outputs much more volume than a 3.5mm audio jack, so it's only natural that the bass especially vibrates more and causes this cracking noise. Solution is to decrease the volume on the phone by 1 or 2 levels.

Pixel 4a - Headphone Jack Max Volume Inconsistent

Has anyone noticed the max volume out of their headphone jack is typically very quiet, but at times will top out at a normal max volume? I use an aux cable to hook into my car stereo and always have my phone set to 100% volume. My Note4 and Note8 both play at identical volumes with the same MP3 files, but my Pixel 4a is significantly quieter. With the windows down, I turn my car volume up to 11 (normally) which is quite loud. On the pixel? The car volume at 18 is ALMOST that loud, but at that point is overworking the amp and degrades the quality substantially.
Here's what's weird. At random times the Pixel max volume will actually be slightly LOUDER than that of my Notes, again with the same MP3 files. When this happens, if I unplug the aux cable and reattach it'll go back to being quiet. This issue is system wide and doesn't affect just one app. YouTube, VLC, etc. all suffer from this. Has anyone had this?

I noticed it too on my 4a today when I tested it. My Nexus 5 and Pixel 1 also both had that issue also. Sometimes unplugging and re-plugging "fixes" it temporarily.
A good simple fix is to get a USB-C -> 3.5mm headphone adapter. Best Buy sells the Google branded one for like $8 - $13 in-store. I dunno how good the other brands are, reviews seem mixed when I looked on Amazon awhile ago. With the USB-C headphone adapter you'll get consistent and considerably more volume than the headphone jack. I also think it sounds a bit cleaner, too. Not much else you can do aside from some sort of bluetooth -> AUX adapter.

I have noticed this exact issue on both my current Pixel 4a 5g and even my last phone which was the Zenfone 5z. It's almost like the phone will switch gain from high to low when plugging in headphones, but sometimes will fail to do so resulting in a higher level of volume and scratchy audio. I may follow advice above and try a USB C adapter. I have not found a fix in software for this issue. The only "resolution" is to replug the headphones in until you notice the output volume is lower/cleaner.

Yeah. I can agree with lower volume. But i have one more problem after plug jack. When in song coming to louder parts, my player stops. Theres no notificiation about ears damage or like that. After that i need to press play and then its quiter.
Someone have simillar ?

The headphone jack is not very powerful on this phone, it's something like 0.3v? You need to use a DAC or buy a phone with a better headphone jack... the gold standard has been LG (RIP) and even iPhones back when they used to have headphone jacks. Now it's Samsung but they seem to be dropping whatever ports they can too.

I don't know how about you, but think they finaly fix this issue with new update. Nowy my jack works fine. Someone can confirm ?
