Pixel Audio Dongle on Samsung S8+ - Samsung Galaxy S8+ Questions & Answers

Hi guys,
I am trying to use Pixel headphone dongle on S8+ and for some reason it doesn't work. Before you ask why (because S8+ has a headphone jack), Pixel dongle is a semi-decent DAC with the better output than what comes out of S8+'s headphone jack.
I also have Dragonfly Black external DAC and that one works just fine. I noticed on Pixel dongle, that I can control the playlist (play/pause) with the headphone button, but no sound is coming out. No idea why, all the other phones we can in the house (some dating 2-3 years back) work with the dongle.
Thanks...

No 3.5mm Stereo Jack Output w/ Aux Cable w/o Hi-Fi Mode Enabled in ICS

I've been using a Motorola for the past 2 years and upgraded to a faster dual core (Huawei Ascend P1 LTE U9202L), and faster quad core (Blu Quattro HD 4.5 D450) - both run on ICS 4.0.4, stock ROM (but rooted), but both have the same problem with the 3.5mm stereo jack. I did not have this issue with my previous phones and have no idea why the behavior is so dysfunctional. On both devices, plugging in the 3.5mm aux jack into my stereo does not work. It does not detect as a headset and just outputs through the phone speaker. However, on both devices, plugging in ANY headset, and the phones detect and output audio appropriately.
However, plugging in a 3.5mm aux cable into a car stereo does not work at all. It won't even show the headset icon in the status bar. I've used several cables, in several different cars, but all no love, while iphones and other phones in the house work just fine. This is with both 3 conductor and 4 conductor stereo cables. With the Blu Quattro however, I found a setting in Sound called "Hi-Fi Mode" which enables the phone to specifically output audio through the 3.5mm jack to an external stereo system. If I plug in the aux cable to my car, nothing goes. Enable Hi-Fi Mode, and then I magically get audio output.
What in the hell is Hi-Fi mode and is that something standard to ICS? Is there a software fix where I can just plug in the stereo aux cable like every other normal phone out there, and have it automatically output properly instead of enabling this funky Hi-Fi mode? It's really annoying because I need to use this device for work as well where we sometimes use the Square Reader. That thing won't even detect on either phone!
At the moment, I'm considering buying one of those USB to 3.5mm jack dongles that I've seen phones come with, that don't have a 3.5mm jack. In the meantime, if anyone has any suggestions, I'd really appreciate it.
Many Thanks in Advance,
Chuck

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.

Moto G6 Better (WOW) Sound (found by mistake)

Hi. The audio is okay on the phone. Good with earphones but okay when I use the headphone jack to my car stereo input. Why not bluetooth? Its because direct connect provides the best sound. NOW HEAR THIS. I plugged in my essential phones usb head jack adapter (essential phone has no headphone jack but they do provide a USB C headphone jack dongle) and its like a WOW. I couldn't believe how much the quality of the audio improved. I am talking about tremendous improvement. Like a different phone WOW. Now whether it was due to essential having a dac chip in the dongle (I think it does) I have no clue. I was shocked because normally the question would be why does a dac chip USB C headphone cable work on a phone with a headphone jack? Did Moto decide at the last design phase was to include a built in jack? The dac cables only supposed to work on phone like the essential or the google pixel 2 etc if I am correct.. Well i am da.... sure glad it works on the Moto G6. How you proceed with what you get/prefer to purchase is up to you. I don't know what the end result will be because I truly don't know. The one I have from essential worked miracle wonders. I only suspect it will work with other USB C dongles with a dac chip. Man, i am digging this phones audio improvement. I am like WOW.
Check it out with something like Viper installed and disable Dolby for a little while to see if that also improves the sound. I use an aux cord to play music in my car as well the Viper HiFi Magisk module on top of tweaking some of my head unit settings, and it puts out some of the best sound for music. Can get my old 2004 Carolla to sound like it has a 10-11" sub in it just from the stock stereos and a Pioneer head unit ;p
Not really that big of a surprise, considering that my old Moto E4 would use a pair of USB-A headphones plugged into a OTG adapter. Feel free to call me out, but isn't the USB-C headphone dongle just getting talked to by the phone like a USB sound card?
Most newer (and some older) phones are all capable of USB audio routing. Just take a look in developer options to see some settings.

3.5mm Headset Mic

Hi all. Do I have a defective device?
I noticed my phone isn't recording sound from the inline mic except (very) faintly. These earbuds came with my work phone (Samsung S9) and all the buttons work perfectly. The earbud's mic works perfectly on the S9 and on the 3a thru the Pixel 2's USB C dongle. Just the 3.5mm jack is refusing to record audio.
I thought 'hardware problem' at first but the controls work perfectly and those use the mic circuit... right? So I'm not sure what to think now. Does anyone else have advice?
just tested it. everyone on discord could hear me
I'm a little confused here. Are the headphones/earbuds USB-C? The S9 and the 3a both have headphone jacks, so not sure why a dongle would need to be used in this situation.
Sorry for the confusion.
1. The mic on my earbuds do not work while plugged into the 3.5mm jack (buttons do work)
2. The mic works fine with the USB C dongle
3. The mic also works fine with my S9 (phone they came with)
4. These are Samsung AKG earbuds
Is that more clear?
my wife has a note 9 so i can find her akg earbuds and see if they do the same thing. the earbuds i tested are some ones i got off of fasttech. so maybe it is an issue with the akg ones
just tested the akg ones and they were fine. so it sounds like you have a bad port. i would contact google for a replacement

Question Using wired headphones

I have a Galaxy S7 FE and I have a pair of Sony bluetooth noise cancelling headphones. I can pair the headphones with bluetooth and audio works fine. But sometimes I go on business trips and long flights the battery in the headphones die. In this case I want to connect the headphones using a wire. The headphones have a 3.5mm female connector as well as USB-C. I have tried connecting the headphones directly USBC headphones to USBC tablet and audio doesn't come out of headphones (just tablet speakers). I have also tried using this device and using the 3.5mm cable, still no luck.
Does anyone know how to connect headphones to the tablet with a wire, either 3.5mm or USB-C?
Appreciate any advice.
I am using this one with my Tab S7 FE. Charging and Headphones work even in combination.
