The GSII supports the USB Audio standard, allowing USB DACs (soundcards) to be used with a OTG USB cable.
Does anyone know if it would be possible to backport the USB Audio support from the GSIII kernel to a GSII kernel? Or does this require userland modifications?
Linux/ALSA has supported USB Audio for a long time.
Jellybean supports a new kind of USB Audio but it is designed for use with car docks, and is not the standard driver-less USB Audio standard used by Linux, Mac & Windows. Many people have confirmed that the Galaxy Nexus and Nexus 7 running Jellybean do not support standard USB Audio DAC.
The Samsung GSIII support for USB Audio is unique.
Hello everyone.
A question has arised, I was wondering if it would be possible to use a USB DAC device on our RAZR. Is this possible in any way? Can the RAZR output digital audio via the micro USB?
Thanks everyone beforehand, this is a great community, which has been of great support ever since I got my first HTC Hero.
Best regards.
Hi,
I own a nexus 7 4.2.1. My simple question is wether to wait for support for the fiio e7 dac in a next version, or to root and install an alternative kernel which i'm not fond of. I thought that in the 4.2.1 version at least the nexus would notice there is a otg cable and usb dac device connected, but nothing. Any suggestions.
Hello,
Do you know if there is any flagship-spec phone (Snapdragon 820) with MHL/HDMI out?
I need to connect my phone to Appradio via cable (tried chromecast and miracast, doesn't work well and audio compression is terrible).
Thanks in advance for any clues.
Hi everyone.
Have you had a chance to try it with external USB DAC like dragonfly red? Is full volume available? How are the USB audio drivers implemented? Most phones have some problems with it and I do not want another phone with external DAC working only with one app- USB audio player pro or not working at all.
I'm using Fiio Q1 MK II. Audio works on some roms - MIUI, PE, Syberia. Other roms I tried doesn't work - LOS, NitrogenOS. I have no idea why... Trying to find the solution myself.

Have you found a solution?
I own the same DAC and LineageOS does not recognise it. I have other DAC (an hifime sabre 9018) and it works... I wonder if there's just a kernel change

I went back to MIUI 10.2.2. My fiio q1 mk2 works perfectly on the stock rom. Gonna stick to MIUI for some time before trying custom ROMs again.
I have observed that ROMs released before December 2018 work fine with my fiio q1 mk2. I tested late November releases of PE and LOS and they both work. Late December builds do not work. I'm thinking it's something to do with the source developers are using. I'm not sure if future ROMs will start supporting my DAC. Fingers crossed.

I also tried different kernels (stock, Franco, Sphinx) with PE and LOS. Didn't help...
I have a feeling it's something to do the how the ROM handles USB audio. It feels like the OS is continuously looping when I plug in the fiio. Others have reported that other DAC brands work while my fiio q1 mk2 doesn't. Maybe driver fiio uses is not in the newer ROM builds. I wonder why support was lost....
Please let me know if you find a solution

Thanks for the reply!
I will pass this information to one of the developers on my ROM and see if he knows more about it. I keep you posted!

Which cable are you use to connect fiio Q1 MK 2 with pocophone?
Is it include in package or you buy it separately?
Thanks in advance

I bought the fiio usb c to micro USB otg cable. The fiio q1 mk2 only comes with a lightening to micro USB.
I have Sonata HD II DAC cable which works in all ROMs I tried including LOS, NOS, CrDroid, Reloaded, and AOSiP (all tried in their stock kernels and then Sphinx).
I use both Poweramp and Hiby without problems and sound as good as they should be. I even tried UAAP trial version which recognizes my hardware also (though I'm currently sticking with LOS with Franco).
To anyone with issues, have you tried updating to their respective lastest firmware if there's any?
Hi All!
Just for information regarding Poco and external DAC (DragonFlye Red).
USB Audio Player Pro:
Pocophone F1 is marked as "NOT WORKING ANDROID DEVICES", because of "Massive USB errors"
It works perfectly (at least playing local files up to 192/24) after setting in "USB Tweaks"->"Bus speed"->"Full speed (USB 1.1)".
If left in "Auto" or "High Speed (USB 2.0)" it doesn't work at all.
Also it works "USB Audio"->"Bit perfect mode" up to 96/24. (But it's a limitation of the DAC)
Neutron Player: everything works after setting "Audio Hardware"->"Direct USB Access". But USB Audio Player sounds better.
Currently using the F1 stacked with topping nx4dsd it can decode even 768k pcm and dsd512 no problem.
Can it play Hi res files with it's internal DAC?
I do not have access to an external DAC. Can F1 play Hi Res Audio Files(24/192) with the internal DAC with Hi Res Supporting Headphone on USB Audio Player Pro? If yes, then how? Please Help!
Centrance slim works fine with MiUI, can't say about rest.

Using Sonata HD with the same app and it works flawlessly in Hi-Res
Internal (built-in) DAC of Poco F1

Good question and wrong answer. Question is about the internal DAC of Poco F1, not the Sonata HD ..

I see, thanks for heads up.
For the said question, some players like Poweramp, USB Audio Player Pro, and Neutron are able to play Hi-Res through internal DAC though doesn't good as much as phones with dedicated DAC.
