[Q] USB Speakers - Is it Possible

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.

HMDI connected Android TV Box

Hi folks,
I´m not quit sure if it is an Android problem or a problem with my box.
When I switch off the TV when the box is connected via HMDI the box goes "off" (switching off sound for example) is there a way or setting to keep it on? So I can switch off TV and keep spotify for example on?

Yes!

Yes! I use my Chromecast in this way. What you need is an HDMI pass through device, like a stereo tuner. I have both a Chromecast and Roku dongle plugged into the HDMI ports on my tuner (it has a total of 4 hdmi ports) . A single HDMI cable then runs from the tuner to the TV. The sound comes out of my stereo speakers, not the tv, and I use the stereo's remote control to switch inputs (the TV itself is never changed from its HDMI1 input). This allows me to listen to the audio without having the TV turned on. Tuners with HDMI pass through can be expensive, but I got lucky and found one, virtually brand new with 4 HDMI inputs, at my local Good Will for $65.

I found a solution which might work. You need to "block" pin 19 from HDMI which reports powersaving / energy modes. I just need to try it at home

USB DAC

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

As One Plus 6 got USB Host?

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
