hi guys,
When I use UAPP and I attach the usb dongle to my pixel 2, I can see a couple of scenarios:
1) set the usb dongle as USB Dac;
2) use the HiRes/Android driver to output music.
Q1: In the first scenario the music alway flow out of the Dac at 48khz/16bit, is it a USB Dac limitation or could it due to UAPP ?
Q2: In case a go for HiRes/Android driver I can use a "bit-perfect" approach... fine! My doubt here is that the usb dongle works as an "analogic bridge" since I'm probably using the phone internal Dac? Could it be a real?
Of course my final intention would be to use the USB Dac in a "bit-perfect" mode (variable rate 44.1, 48, 88.2, 96khz), but it seems to be fixed to 48khz.
Any feedback would be appreciated.
thx
I don't believe you can use the dongle as an "analogue bridge". Whatever it is doing, it's using the dongle's DAC.

Hi guys I was wondering if it was possible to get the transformer to output music through the USB ports. I have a set of portable Creative speakers which have great sound and would love to use them with the transformer. They are powered and receive audio from USB
It is very possible, but you'd ave to add the device modules (drivers for the device) to the kernel yourself because it isn't native. I've been trying to get USB headphones working for a while.. :/

Got work usb audio on tf101 with CM10. Just kernel modules for usb audio are not enough to get sound from apps to be routed through the DAC. It's also needed to patch vertana audio driver.
I know it's been a long time but I just got around to rooting my TF101 and actually enjoying it. Has anyone done anything similar with speakers or headphones

Lollipop - Any Improvements?
Has anyone been able to get USB Audio working in a Lollipop ROM given the improvements to USB host?
So far, no luck for me:
KatKiss Lollipop 5.1 #21 ROM
JBL Pebbles USB Speakers connected to the dock
My tablet recognizes there is a USB audio device as the audio stops after connecting.
Also, disabling auto routing of audio to USB audio devices does what it supposed to do - so detection works.
Connecting the headphones out to the aux in of the USB speaker didn't work. Tablet speakers shut off but no sound in the USB speakers.
I could get it to work is powering the speakers from an AC charger and using the tablet headphone out to it.
Also, USB Audio Tester app works in that it can detect the USB device and it was able to play audio out of it (tested via connecting int mic to ext speaker mode and raising the volume bars).
To my understanding from the developer's description, that app uses non-standard interface to output USB audio.
The speakers work fine on Windows and Chrome OS without drivers so I was hoping it was plug and play.
Update:
I did note that I had to raise the in-app playback control volume bars first though to work in USB Audio Tester app.
Also, when connected to a computer and using the Aux In of the speakers, my phones and tablet can play audio.
Based on power draw of a USB charger I connected, the speakers use 0.6W idle and about 1W max.
Therefore, I'm thinking maybe it fails the USB enumeration in Android and the default 100mA is not enough.
Anyone know how to check the USB host enumeration settings?

Since we are talking about USB HOST, maybe it's important to use USB OTG cable, I reckon, as not all USB cables are equal. This has just recently struck me, because I used USB cable that came with my soundcard the other day. Its of great quality, sure, but I'm almost positive it's not OTG. My audiocard is externally powered, so on the other hand it might be just unimportant in my case...
USB Speakers of all sorts have generic DACs in them that require no special drivers and have to work out of the box on any system as long as USB connection and standard USB functionality are intact. Success stories of USB Audio working under Lollipop are rather abundant.
If USB Audio Tester works for you then USB Audio Player PRO should too, those are made by the same guys AFAICT. UAPP is no free app though, costs a sum, and sadly its proprietary driver(yeah, those devs apps use "non-standard interface") only works inside the program, one cannot watch Youtube or MX Player by using that... Compatibility list is on the devs site. My card, E-MU 0404 USB is listed as compatible for only RECORDING, not playback. Heck, I'm absolutely certain, I saw someone on some forum claiming they got same card totally working under UAPP and that wasn't even on Lollipop! Anyway, my trial and error continues...
I don't have a USB OTG cable for the TF101.
Instead, I'm using the keyboard dock that provides two USB ports.
It should be the same thing.
It is very good to hear that USB audio is working for a lot of people on Lollipop.
I've tried testing my speakers on more Android devices - my Nexus 5 and Samsung Galaxy Tab S.
Like the TF101, the speakers are detected as the OS switches over (no more audio out of built in speakers) but no sound out of the speakers themselves.
I'm leaning towards these speakers are not compatible with Android yet.
Sigh - non-standard standards.
I was under the impression that Lollipop supported USB audio devices OS wide, but I haven't been able to get my two Schiit DACs (Modi and Fulla) to work in Google Play Music. I also have a pair of Audioengine A2+ speakers (USB connection) that do work. All three of the devices are detected by USB Audio Tester and are connected via a USB OTG adapter and powered USB hub.
I've reached out to Google and Schiit. So far, only Schiit has responded, but they only said that USB audio may not work with all Android devices and that they didn't have a Nexus 5 to test. I'll update if I get any response from Google.
I haven't been able to find much on the internet about USB audio in Android. Google has two pages (1, 2) on USB audio didn't lead me to anything to help solve the problem, so if anyone is aware of other pages on the topic, let me know. Additionally, the second one only seems to confirm that the Nexus 5 should work since both of the Schiit devices are USB Audio 2.0 compliant. I'm also aware some apps support USB audio, but I need to use Google Play Music since I could only store a fraction of my library locally.
Hi there,
Anyone tried with USB DAC?
I tried, I can manage my Soundblaster E5 settings, but no sound. Same with USB audio player Pro and Deezer etc.
USB option (in developer options) enables the USB sound.
Any idea?
Second issue:
Soundblaster E5 has BT/NFC connect possibility. With my old phone (Asus Zenfone 2) was able to wake up the DAC with NFC, after I touched the phone to the DAC. Huawei Mate 9 isn't able to do it.
Hi, I'm having the exact same issue with another usb dac. Did you find a solution?

I have a sound Blaster E3 and dac work as it should. USB otg must be at phone side. If you use provided otg cable on dac. It will not work. I used a small micro USB to USB C head to connect the micro USB otg cable to mate 9.

What did you set up for USB CONNECT MODE? MTP, just charge etc?
Any settings in developer settings or so?
I tried with USB male - USB C OTG cable, with SB original cable + Huawei converter micro to usb c, not worked

Not yet.
Anyone got a USB dac working? Which amp and which type c adapter/cable?
I have a Dragonfly Black and it worked perfectly with an Amazon USB-C OTG. I didn't change the setting for the connection type, it automatically identified it as a device that was a slave and supplied power to the DAC.
Mines a bone stock US model fwiw
My Mojo works fine using the USB-C to Micro adapter that came in the box of my Mate 9 Pro.

Ops. Seem like my notification not working. Sorry for some late reply. Mine do not appear any option. It certainly do if I plug it the other way around which make the dac not working but prompt the mtp and charge option.
My Fiio E17K works flawlessly with an OTG cable I found on Amazon.

I can't link but it's a:
Meenova
4.6 out of 5 stars 17 Reviews
USB Type-C-to-MicroUSB OTG Cable for connecting Camera/DAC/Media Player/Game Controller/Portable Hard drive/MIDI to Smartphone/Tablet/Computers
$7.99 USD
So I played around a bit with my S.M.S.L. idol+ today and found the following:
Neutron Music Player (Eval) works fine
USB Audio Player Pro produces loud noise, none of the USB Tweaks work, neither does Bit Perfect turned on and changing the buffer size results in the Player failing to play the songs. It doesn't make a difference if I try to play 64kb/s MP3 or 24bit FLAC..
Poweramp recognizes the DAC and seems to play but the headphones stay silent. Strange enough one time after trying some things with USB Audio Player Pro, Poweramp suddenly worked fine. I couldn't reproduce that though.
So of course I could use Neutron Player but I don't really like the interface and since I already bought USB Audio Player Pro and Poweramp and it seems to be a configuration issue, I would prefer using one of these.
So if anyone has an idea what else I could try, I would really appreciate any help
USB Audio Pro says 'USB Audio device initialised' but App USB Host check says can't find USB Host??
Went on one plus chat just before buying op6 but wouldn't commit to saying if it had or had not got USB Host! Have OP3T which works OK with my Audioquest Black DAC.
Have connected the DAC to op6 and it plays thru USB audio Pro, but it doesn't sound great. Streaming Tidal & Spotify directly produces heavy glitching esp at start of tracks, and again doesn't sound great. . No glitching thru headphone socket. Have been in touch with Audioquest and they seem to think one plus android version of op6 is switching USB off
So wondering if USB Host is supported, or what others experience has been ?
Any update? Did you managed to fix the issue? I am planning to get Audioquest
Hey guys,
Did any of you manage to make the google usb-c to jack adapter (the one provided with the pixel 3) to work with uapp in any of the USB dap mode?
The adapter is detected and initializing correctly but doesn't give any sound.
The Google earbuds work fine with uapp, and the adapter is working fine without the USB mode too, so it's weird. I can't find any information on that anywhere.
It's doing the same on both Android 9 and 10.
So I guess nobody ever tried/cared about uapp on the pixel 3?
