Galaxy S and USB Dac

Has anyone of you tried USB DACs with custom roms which support USB-OTG? If so, post brand of USB DAC, user experience and issues you may had.

why would i if the samsung galaxy S is an excellent DAC in itself..just have flash the voodoo kernel ( or a kernel with voodoo sound)..or get the voodoo app

An external DAC/AMP would be still a great option as an upgrade. Still there are better players out there. I'm also using a Sony Z walkman as portable player and its on a league of its own.

Possible that no one has used an external dac from the Galaxy S. I was thinking that all those custom roms listing this feature would have caught some interest.

USB DAC support
So, we have Jelly Bean ported for our devices. Any news about USB DAC support?
In CM10 usb dac can be detected in USB Host Controller app, but sound still plays through the rear speaker of the phone. At first I thought to change /etc/asound.conf to make sound go to the external usb dac, but it seems that this file is not used by the system at all - it can be deleted and everything works fine.

Any developments on this? I'm wondering if I can hook my old i9000 to the phono input of my Hi-Fi and play music stream via DLNA. The built in DAC is very good apparently, but If i can attach an external one, even better.

[Q] SGS as a sound card?

Hello. I was wondering if it is possible to use phone as a sound card via USB cable? (wi-fi will also do) I broke my 3,5mm audio jack on a laptop. So if you guys know any app or anything at all, please do tell me.
Thanks in advance.

audio over wi-fi impossible because of bad latency (slow delay)
audio over usb possible in theory, but requires firmware modification and pc driver modification (I don't think anyone done that)
audio over bluetooth possible and must be easy, probably work on any firmware.

I am aware of the low prices of USB sound cards. I was just wondering if there is a way to stream all audio from pc to phone via USB cable, for android everything is possible. Well if there is no way to do that, I can live with that.

USB Audio

I'm trying to make it working. I have Sound Blaster Surround 5.1 USB external sound card connected to RAZRi through OTG and powered USB Hub. Card is recognized properly but I can't make it play through it. I tried few apps to redirect sound to USB host but no luck.
Android 4.1.2 should have alsa driver and it should work without any kernel modifications.
Any suggestions??

Anyway to play music thru usb port on car radio?

I'm wondering if it's possible to play music on a car radio (or any usb input) thru the usb port on the note 4?
Any app, mod, hack, tweak to mount a certain folder (music) as a thumb drive?
I have several usb input audio devices, but I can't access anything when I attach the note.

I feel you, I tried to do the same with no success ended up buying a 3.5mm headphone jack to rca for my car stereo ?

Yeah that sucks

So you're trying to MOUNT a USB DRIVE filled with music and play it to your car stereo? You using a 3.5mm cable or Bluetooth here?
I have some USB OTG cables (really cheap, ebay) and play the music from my SD card using PowerAmp (FLAC Playback, also allows folder choosing; your USB drive?) through the OTG cable, to my Fiio E07k, then to my headphones/speakers. Works FLAWLESSLY, and if I plug anything to the headphone jack simultaneously, it will re-route the audio.
Hope this helps.

I want to use a usb cable from my phone into my car radio usb port and play the music that is in my phone thru the car radio using the usb cable and not the 3.5mm head phone jack.

i believe this is a feature in lollipop to enable audio through usb. gonna have to wait
"Android 5.0 has added official support for USB audio devices (both input and output) along with lower-latency audio input and the ability to mix up to eight audio channels. All of which means one, amazing, thing: "

I want my phone to act like a usb thumb drive when I connect it to my car radio thru the usb port.

I can't remember, I set it up a long time ago. It's a 64gb uhs1 card. I remember I had to format it with a pc app to get it to be recognized in my (then) Galaxy S3, and I simply moved it in to my note 4.

OK, with that being said, what stereo you using? Display style or single din?
Is it linix based or android?
Brand and model number?

I've got a pioneer single din in the wife's car (can't remember the #) and I've got a Kenwood dnx5120 double din, which has a usb port that will read a usb thumb drive or a hdd (or iPod / iPhone) but will not "see" my phone when connected usb.
I figure if it can read a usb thumb drive or even a hdd, why can't the note 4 mount itself as a thumb drive (external sd card) and allow my radio to read it's content and play it's mp3's?

Ever found a way?
Im in the same situation.
Ive tried the apps that enable usb mass storage mode on my sgh-1337m galaxy s4 and while it works and my computer recognizes my sd card as an usb drive, my car stereo still does not.
Any other way or USM enabler that works?

I have never found a way ? sad to say. If anyone can point us in the right direction if that direction even exists, that would be great.
Sent from my Samsung Note 6

I just bought a Kenwood KDC x701 and I had a very unusual set of circumstances. When I plug in my HTC 10 to either USB cable one or two nothing happens other than charging the phone. The Kenwood radio does not recognize the HTC 10 at all. I thought this was completely normal as I was not trying to mount the HTC 10 internal storage to play music files as I have no music files on my phone except audio recordings I make myself a phone calls and such. I am able to stream music via Bluetooth from the phone to the radio just fine and that's what I've been doing this entire time. The only thing I listen to is tidal music streaming service. So the other day I went to plug in my lgv10 to charge while I was driving and a funny thing happened. The radio display indicated it was reading and then went into a hand mode, it is literally called hand mode LOL. The next thing that happened was a message popped up on my phone asking me if I wanted to download a Kenwood app from the Play Store I hit cancel. Then all of the sudden it started playing music from the Tidal music streaming app. Although no information was displayed on the radio I was able to use the buttons to skip forward and Skip ahead of the different tracks but I am not sure I am able to pause or play music on the radio controls. I am not sure how it is possible to stream digital audio through the USB cable directly into the radio. I have no audio files stored on my phone on either phone and I'm not even sure how to mount internal or external storage on the phone if I wanted to use the head unit to access any audio files. So I called Kenwood and they said what I described is not possible with any of their head units. They did say that I should be able to mount my internal or external storage on my phone and use the Kenwood app two act as a music player and play the files on the phone and have them information sent to the radio. What it sounds to me like is I have a USB OTG situation with the LG V10 and no one knows why. Also of note I am unable to stream music from the lgv10 to the Kenwood stereo and no one knows why Kenwood does not know why. All of the track information is displayed on the radio I can control the songs going backwards and forwards the timer countdown xcetera but there's just no music. I will say streaming music from Tidal music service streaming app sounds much much better through the USB cable versus Bluetooth. I can't believe how much better it sounds over the USB cable it's like adding an amplifier to your system. I will try to make some videos and if this helps anyone that's going to be awesome. Also of note when I select source to USB when I have my lgv10 plugged in it calls the source Android1. This totally sounds to me like USB OTG. What do you all think and has anything like this happened to anyone else? And this does not work with my HTC 10.

I don't believe that this is possible any longer. It was possible under older versions of android (pre kit kat i believe) where the "internal sd" was seen as a physically separate storage device instead of being mounted under /data/media. Once they made this change, they had to swap from USB Mass Storage mode to the annoying Media Transfer Protocol. The reason Mass Storage had to be dropped is because of how it functioned. When you allowed access to your "internal sd" it would have to dismount it from the OS to give the host device plugged into the USB port exclusive access to the file system. Since they made the move to mounting it as /data/media there is no way to give that exclusive access any longer. Trying to dismount that /data/media to give that exclusive control would yank away all of the writable media away from the OS. Android would likely crash, or at least nothing would function any longer.

OTG support on Moto Z Play

There is support for OTG to Moto Z Play? I found some OTG adapter for USB-C, but I'm not sure if there is compatibility.
Thanks in advance.

I bought a Lexar USB Flash drive and it does work

I tried a couple of type C adapters, and both work.

I got ahold of an Apple USB-C cable and it worked on my Z Force, so I'd say it's a pretty good bet for the Play as well.

Anker USB-C to USB-A
I have bought the OTG-USB from Anker (USB-C to USB 3.0).
Works perfect. Testet 4GB USB 2.0 and 32GB, 64GB and 128GB Lexar USB 3.0 Sticks with "exFAT".
All working fantastic.
Ciao RZ

Thanks for the post. Reminded me to dig out my adapter and try it with my USB thumbdrive. With my battery pack, this thing would last forever on a airplane

I use sandisk Otg usb drive works perfect!!!!

the speed are really slow . I am using a usb-c to usb and the speed are only 2MB/s while I get 150MB/s witht eh same USB stick on my pc ,

The nonda USB-C to USB 3.0 Mini Adapter does not seem to work - I have contacted their support and am waiting to see what thy say.
Tried it with a two USB drives and a USB DAC. All of them are recognized that they are connected but the drives says they are corrupt and the USB DAC outputs garbage noise.

It used to work with Meenova micro usb card reader and a c-type adapter, as with c-type card reader, I also could connect and read/write hdd (ntsc and exfat) BUT.....
ALL OF A SUDDEN IT STOPS EVEN RECOGNIZING ANY USB TYPE DRIVES/CARDS
The readers led don't even light up.....
HEEEEEELLLLPPPPP!!!!

Few file browsers work. FX Commander and Solid do but differently, I use both.
I cannot find a music player that does. Please post yours that does play through OTG.
I have a dash 1 phone.
This is my adapter https://www.amazon.com/gp/product/B0194WSKOM/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1

Hey, I am wondering if anyone else has tried connecting a ps4 controller over OTG. For me it just doesn't work. I don't know if it's just my method of plugging it in (USB C to Micro B to USB A to PS4 controller)

Did you try the integrated music player of Total Commander? It should do. Currently do not have my OTG handy, if it's complicated for you I can try somewhen the next days.

Total C and it's plugin have to create a dup of the file you want to send to a player. Pretty nonfunctional for quarter to 1 GB music file. File Commander just links the file, instant player transfer.
Well, Poweramp is claiming to support any phone for native DAC abilities. They have a request forum. I posted a thread in Q & A. The latest version will browse our OTG but only uses our DAC to 44k. Ours is capable of 192k. USB audio does use our DAC fully but no OTG and no plans to do so.
If you tolerate 44k get Poweramp.

I don't have a USB-C OTG cable, but if you press and hold both the share + ps buttons while the controller is in standby it turns on BT.
Then on your phone go to the bluetooth menu and connect and it works wireless. Why use OTG when you can use wireless

Send to a player? What are you talking about? I meant the integrated player of TC, not sending to a player. Just tested it out: long select a file, press play, and it instantly plays. I'm quite sure there is no limit. Select some music, add it to the TC player queue, I'm quite sure it will work.

Using TC while browsing OTG:
When I select a flac file(bitrate 192k) and ask TC to open as audio, it makes a copy in internal memory. I would then play it with https://forum.xda-developers.com/moto-z-play/themes/music-players-one-standout-dac-to-192k-t3533577 .
I did not try it's internal player as it would use the DAC of our phone at 44k bitrate, standard CD quality.
My concern is music played from OTG. I did not try it but I think it would need to duplicate the file even when playing from it's internal player

Did not know that other behavior is possible. For me playing at a higher rate than CD will make no difference, my ears are not that good.

Don't think so. It should just play. Of course it will use some buffer for playing, but you shouldn't notice that.
My recommendation was "try TC with internal player". That requirement with more than 44 kHz came later. You wrote "TC does not work, but I didn't try the internal player." Guess I'm out of here now. Good luck!

I know I can use wireless, but most of the time I've tried it, it's been laggy AF, that's why I would like to use OTG
