As it was reported for Galaxy S III on 4.0.4 there is USB Audio snd-usb-audio usb class audio driver present. and it enables the phone to stream digital audio directly to external DAC for perfect audio quality.

I badly want this as well. I have a locked (but rooted) bootloader Ray so my options are limited in terms of JB roms but I also have a Phillips S351 which supports USB audio, it would be great if there were a patch or a port or something.
I'm using FXP's CyanogenMod CM10 and I've got an audio.usb.defaut.so file in /system/lib/hw ....if someone (with an unlocked rooted phone) has one of these USB DAC's thingies then this might worth testing....
Has anyone got the official car dock working on a custom ROM with audio out by the USB slot?
I have the option ticked in device settings but audio keeps playing through phone speakers?
I use it that much I'll swap to any ROM that has it working.
Or kernel.
Swype'd at pace from my Galaxy S2
I tried the pacman 4.4.4 rom.
I have an usb ON to go cable + Go vibe mini U dac (which is usb).
I see the USB- DAC turned - powered on.
However I do my headphones in and music does not play.
The developer doesn't have time I read for android anymore.
I did see in sound settings the option : Dock- Audio. But it was greyed out, either shifted out of the rom, or my device is not recognized?
Does anyone please know a rom that might work with this???
Thanks!
Hello,
My question is quite specific, but I am currently running RR 5.8.4 (20170914) and I noticed that OTG has never worked for me (although it works when in TWRP)
I never minded so forgot about it, but I recently got hold of the Hi-Fi Plus cheaply only (£35) and wanted to try it out. As it turns out, it doesn't work and I was wondering whether;
Is this a kernel issue - can I flash an appropriate kernel to get OTG (and hopefully Hi-Fi plus support)
Or, is this just due to the Rom - should I flash a stock rom (e.g fulmics?)
Thanks!
*I have edited the Title as some of the information has changed based on my research, see my replies below*
Just as a follow up to this - I just flashed Fulmics and it still doens't work. I wonder if they only work on completely stock Rom. I will flash back to stock and update accordingly.
I also will try out OTG to see if that works.
OTG on Fulmics also doesn't work (if anyone is interested).
I hope I am doing something wrong here because it would be great to get this going

Can confirm the Hi-Fi module works on Fulmics, both internally and as an OTG device. If you're using it via OTG, I recommend USB Audio Player PRO. Their custom USB device stack works a lot better than Android's default USB audio device support. Arguably works better than using the Hi-Fi module connected directly to the phone via LG's own apps.
-edited to add: If you're using the Hi-Fi module via OTG or even connected to a PC, make sure you have headphones plugged in. For some reason, the device shuts off entirely and is not recognised unless this is the case.

Thanks. I am surprised by this - I went right back to stock (20K) and it still doesn't work for me (even with headphones plugged in). I wonder if there is something I have missed - I have no OTG support on any of the ROMs I have tried (Fulmics, RR and Stock (20K)
I thought the process would be easier - I expected to be able to listen to Spotify with the DAC - is this the case?
I have taken my phone completely back to stock, (H85020g_00_VMC_GB_OP_0703) and plugged in the Hi-Fi plus and it still doesnt work:
The "Friends" app detects the the Hi-Fi Plus
the 32 Bit DAC settings item is greyed out
I plugged in two different types of headphones
I am now at a bit of a loss as I still don't understand why OTG doesn't seem to be working either (obviously related), so the wider question is, why?
I tested out OTG on TWRP and it works, and I tested the cable I purchased on a Huawei P9 and it also works so I dont think it is the cable.
For reference, the OTG cable I have is this:

Any assistance would be greatly appreciated! Should I just return the phone and get a new one?

Does it play music through the Hi-Fi module at all when you plug in earphones? The stock ROM specific things (like the little Hi-Fi symbol in the notification bar) don't work with it attached as a USB device, it is just picked up as an Android USB audio device.
The cable might also be a factor (although yours looks like it should work); I've found the module to be picky with what will and won't work. Attempting to use the short USB C -> micro USB cable included with the Hi-Fi module (with a micro USB -> USB C OTG adapter, of course) for instance did not work for me.

Hi,
No it doesn't play music through the module, it just plays out of the speaker. If I put the headphones in the top of the phone, then it plays from there, but not from the bottom.
I think there is some issue with OTG, rather than the Hi-Fi module as it works fine when I plug it into a computer. I don't really know how I can diagnose it further. I have verified that OTG works in TWRP (and with other devices) so the cable seems fine. I'm not really sure how to proceed from there.
Thanks,
Charlie
The same thing happens to me in my g5 h860n. I have tried different firmware versions and the problem remains the same. Does anyone have an idea that I should try?
Hello! I have the same trouble. Lg G5 H850 GBR, V20v-EUR-XX, unlocked bootloader, root Magisk, stock ROM and kernel. HiFi plus recognized when direct plug into the phone (not tested with OTG-cable) , but, as was writed by Chalima, it doesn't play music through the module, it just plays out of the speaker. If I put the headphones in the top of the phone, then it plays from there, but not from the bottom. Does anybody know, this trouble of hardware, software, or a HiFi plus?
You probably checked this, but I say it anyway:
Developer options/media/USB audio routing ??
Don't disable this.....
Yes, I try with enable and disable this - not working. Also in prog Device Info HW in USB tab I see nothing.
what can the pixel 6 usb plug do and what do you use it for (other then headphones and adb).
if you have tried OTG to a ssd usb drive how fast are the transfer rates in real life? i heard there is no video to hdmi like Samsung. and the audio requires a digital to headphone style . can the pixel 6 do 7.1 surround sound? or just stereo audio out? any other features from the usb plug ( eg. direct to printer printing?)
