[Q] Moto E and exteral DAC (USB) - Moto E Q&A, Help & Troubleshooting

The Galaxy S3 I was using as an mp3 player died, so I'm looking for a new music player. I was outputting to a Fiio E07K via USB OTG and would prefer to continue to do so.
I know that Lollipop should bring native support for USB audio out (as far as I understand, it varies from device-to-device because of software), but I was wondering if anyone could confirm that a similar setup with their Moto E works.
Thanks!

Play music through USB?

Hi,
I wonder if it is possible to play music through USB. It doesn't work out of the box with CM 7, but maybe the is a hack or an app that would accomplish this?
Btw: Merry Christmas!
When you say: "through USB"; do you mean playing on the phone (with Music player) having audio output through usb? I haven't heard of one, but it could be theoretically possible as I have a USB Fm transmitter (also, docking bases have an audio out port) which plugs into the phone and transmits audio - so im sure a hack could be built? Otherwise, if you are asking about the ability to plug it into a USB port present on most modern stereo systems - the phone can simply be mounted and the stereo system would read it like any flash drive (have done this in my car)
Do you mean using the usb headphones?

Using SGSI i9000 to stream music from NAS etc to my Hi-Fi

I’ve been looking a various solutions to stream music to a Hi-Fi such as Squeeze Box and Sonos, and am wondering if I could use my trusty old SGSI i9000 to stream from a NAS or other DLNA enabled device? I believe to Wolfson DAC is quite good for a phone, so I could connect the phone to the amp with a phono lead, but I also wonder if I could attached an external DAC via a USB adaptor to improve the sound output. I know this can be done on the S3 and some tablets, but not sure of the situation with other phones. I am ok with routing and custom ROM’s if that helps. Please note I do not want to play music stored on the phone, as my library is already 200gb and rising, but use it as a conduit to get the music from storage to the Hi-Fi

Hi,
You could try ArkMC app on Google play , it's streaming video by DLNA , it's well done
Regards
Hi Brya, thanks for making this your first post! The ArkMC app looks good. There are many DLNA streaming apps and this looks like one of the better ones.
My situation though is that if my Hi-Fi isn’t a DLNA device and only has phono input, can the phone stream a file from a NAS etc, play the file on the phone and output it through the headphone or micro USB socket to an amp. I think now that I’ve typed this out that the answer to this is yes.
So next question, how good is the audio quality going to be from such as set up? I think this depends on the DAC in the phone, which is quite good for a phone but probably not great compared to £300-£500 mini system. I’d welcome feedback on this.
Then the question is, can I connect an external DAC via the micro USB port?
For info, I haven’t actually got a Hi-Fi at the moment. I’m weighing up buying a mini system that includes a network streamer against more expensive and better sounding separates that do not (though they may have a USB input) and seeing if this would be a viable option for playing digital music.

[Q] Play audio on Android through USB ipod dock/receiver/etc?

Hey all,
I'm wondering if it's possible to play audio on my Android devices (SSG Note 2, TF701, etc) through an ios enabled USB receiver? Specifically, my car has a usb port meant to plug in an ipod/iphone to stream music. It seems only to work with ios devices. Is there anything I can do on the phone/tab to spoof the ios and thus play audio in my car via the USB? The stereo does have bluetooth but I'm really looking to use this for videos to eliminate lag.
Any help is greatly appreciated! Thanks!

DTS/Surround5.1 output via MHL usb to hdmi not working, only stereo, why?

I'm using a LeTV x900 (or Le Max), which sports the Snapdragon 810 as well as USB Type C.
I'm using a USB-C to HDMI MHL adapter (made specifically for this brand of phone) to output audio to my yamaha receiver, as I want to listen to DTS tracks on my home stereo. The receiver sees the HDMI signal from my phone. I use MX Player, which plays the DTS tracks fine (I have the one with DTS support and the right codecs installed), which plays the files just fine. Yet for some reason the receiver is only receiving a stereo signal, so its only giving me 2.0 sound, not see any more than 2 channels in the first place. I'd like to at least play 5.1 (if not 7.1) files. I can't for the life of me figure out what step I'm missing. I even went so far as to install Dolby Atmos on android but that was a no go too. Any ideas?

OTG / Hi-Fi Plus on H850

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:
https://www.amazon.co.uk/gp/product/B01COOQIKU/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
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.
