I dont think he thought it was a disaster but rather speaking his mind

You are right they do need to speed up the app if they want everyone to convert to it.
[Moto G Q&A, Help & Troubleshooting] UnknownAX:
I already found out, that the Moto G supports USB OTG, but would it support USB DAC's (digital-analog audio converter) ? If any Moto G owner owns a USB Dac or atleast something compareable like a USB headset or USB headphones, I'd be really thankfull if you could try it out.

The dac/headset needs to be plugged into the phone using a USB OTG cable.

Thanks! :)
[Moto G Q&A, Help & Troubleshooting] shaftenberg:
Works!! BUT:

I hooked an USB-OTG to Moto G, in there a Creative USB Soundcard with analog/digital output. Analog didn't work (must be the soundcard), but digital. I connected the digital out with a light cable to my RME environment and I could hear the music but with wrong frequency and crackled - but it works :D

Moto G has enough power to let the soundcard work.

[edit]

Hooked another soundcard in, this time analog works but wrong sample frequency and oversaturated, no option to control the volume.
[Moto G Q&A, Help & Troubleshooting] UnknownAX:
Wow! This phone seems to be even more incredible value than I ever thought.

The problems that you mention sound pretty weird, though. The first thing that I'd suspect is the lack of special drivers for the soundcards on the Moto g. Maybe a simple DAC that doesn't need any special drivers would work better.

In fact, stock androids rarely work with any USB audio devices. But there's a app that includes special drivers and makes most USB-OTG enabled droids work with USB audio devices. You can the trial version (link in the description of the app) of it if you like:

https://play.google.com/store/apps/...=organic&utm_term=usb+audio+recorder+pro+demo

Be aware that the trial only works for 15 minutes and it doesn't play the usual audio formats. ( .flac works) If you try it, you should put a flac on the phone before installing the app.

Oh, and who knows how well this might work when CM and KitKat arrive!

Thanks a lot for your help.:)
[Moto G Q&A, Help & Troubleshooting] shaftenberg:
With the app it works, without stuttering and you can control the output volume, although there was an error warning at startup regarding main volume :D

I tried to record something, but hadn't enough time. First try was unsuccessful unfortunately.
[Moto G Q&A, Help & Troubleshooting] UnknownAX:
Well, that's nice to hear. Maybe some Custom ROMs (Cyanogenmod in particular) will have better support for this without the app.

Anyway, I think I'm going to get this phone (Christmas is coming :p). Usb audio support (atleast with the app) is crucial for me, so thanks for reporting that it works.:good:

One last thing though, what make and model were the two soundcards that you used for testing?
[Moto G Q&A, Help & Troubleshooting] shaftenberg:
First a cheap Creative USB Soundcard, second a DJ-Audio-Player from EKS (www.eks.fi) which has its own soundcard per player.
[Moto G Q&A, Help & Troubleshooting] UnknownAX:
Could you test this on the faux kernel that your running atm, Shaftenberg? :o

Most people who have tried it on the stock ROM have experienced the same glitches that you mentioned in your first post. On the other hand, there's also one report of it working fine, with the Google music player. The DAC is probably the biggest factor.

Anyway, I'm just waiting for the 16gb version to be available....
[Moto G Q&A, Help & Troubleshooting] nlra:
I tried 2 DACs. One was a CEntrance DACport LX flashed with the iPad firmware, and the other was a cheap off-brand thing (ELE EL-D01 on eBay). Both of them "worked", but I encountered the same issue with each: I tested both by playing a Youtube video, and the audio was not playing back at the proper sampling rate. The audio was slightly slowed down... as a result, pitches were slightly lower, and the audio lagged behind the video pretty significantly. If I had to guess, the audio was 48kHz, and Android was trying to play it back at 44.1kHz without resampling it first.

Why it was doing this, I have no idea: on a Nexus 4 running stock Jellybean with jacknorris' patch (which, AFAIK, doesn't pay attention to sampling rates but just assumes Android will handle that properly elsewhere), this works perfectly. However, it was fascinating/encouraging to see this work at all on the Moto G: it means that with stock firmware, not only does OTG/USB host mode work, and not only does the kernel have the stock Linux USB DAC driver compiled in, but the Android framework itself attempts to use the DAC, which is *definitely* not true with plain-jane AOSP.

One thing I was sad to see (which also seems to be true of a LOT of other Android phones that support OTG out-of-the-box) is that if I injected 5V from an external source into the USB power lines, the phone would NOT charge as long as OTG mode was engaged. Which means that, at least with the stock Moto G firmware, you can't both be in USB host most *and* be charging the battery at the same time. (Interestingly, the very first time you plug the power in, the phone says "charging", but it's quickly obvious it isn't. If you unplug and re-plug the power in after that, it will not show the lightning symbol on the battery any longer until you reboot the phone. Normal USB chargers continue to work without the OTG cable without requiring a reboot.)

[Moto G Q&A, Help & Troubleshooting] UnknownAX:
That makes sense to me. But what would happen if we played a 44.1kHz track? It wouldn't have to resample then, would it?

Maybe that's why there is a report of it working with google music player...maybe he just happened to try it with a 44.1kHz track?

I'm pretty sure this will/can be fixed with a ROM / Kernel. Like USB OTG charging, it's just a matter of time (I hope). Both things have already been successfully enabled on many different devices.

Thanks for the info, luckily I'm not the only one showing interest in this.
[Moto G Q&A, Help & Troubleshooting] tapasmonkey:
It most definitely works with my Moto G and my FiiO E17 (connected via a generic OTG cable)

Trouble is, although it ALMOST worked, I got sporadic but impossible to listen to skipping/stuttering when using Poweramp or the native Google player app.

I finally found an app made by the same people who do the USB Audio Recorder Pro as mentioned by the poster, called USB Audio Player Pro (can't post the link, being a new poster, but a quick search for "USB audio player" gets to it)

...it costs over 5 pounds, and to be frank it is not the world's prettiest or richly featured player, but it certainly works and the output sound is great.

Anyway, just posting to let you know that it works, at least with my Fiio E17.
[Moto G Q&A, Help & Troubleshooting] nlra:
So here's some good news: after applying the official KitKat 4.4.2 OTA, OTG still works, USB DAC support still exists, and now it even works properly, at least for me! No more strange audio sampling issues: I could attach either one of my DACs and play the same Youtube clip without any difficulty! Audio was perfectly in-sync with the video.

-- Nathan
[Moto G Q&A, Help & Troubleshooting] DukeHarris:
Did anyone manage to get USB audio to work with the Moto G play edition?
[Moto G Q&A, Help & Troubleshooting] jjacks:
Has anybody found a way to enable OTG and charging at the same time? I genuinely enjoy listening to Moto G + FiiO E17 but it leaves me with low battery on the way home which is rather frustrating and makes me to swap charger/DAC during the day.

I don't mind putting unofficial ROM in as long as it doesn't require hardware mods.
[Moto G Q&A, Help & Troubleshooting] nlra:
I have taken ziddey's USB OTG kernel patch for the Nexus 4, which allows both for charging as well as USB OTG mode without an actual OTG cable, and I have compiled a new kernel for the stock Moto G 4.4.2 ROM, and it works great! The only thing is that you have to use a non-OTG cable...if it detects the OTG cable it will shut off the charging. So you will need a USB Y cable to inject a 5V power source to both your DAC and phone, and plug the phone into the Y cable using a standard micro-USB cable instead of an OTG cable.

If people are interested in this kernel, I can post it. You will need to unlock your bootloader to flash it.

-- Nathan
[Moto G Q&A, Help & Troubleshooting] jjacks:
That is interesting. I would be happy to flash it. Is it safe operation? I flashed multiple windows mobile / windows phone devices but no experience with Android mods yet. Any downsides of custom kernel?
[Moto G Q&A, Help & Troubleshooting] jjacks:
Great. Thanks a lot. I will give it a try when I find some spare time

[Moto G Q&A, Help & Troubleshooting] samwathegreat:
Would you be interested in building a compatible kernel for 4.4.4? Is the source available? My Moto G is brand new pre-installed with 4.4.4. so no option to use your 4.4.2 kernel. I would really appreciate the help - I have a project that requires me to be able to charge and host simultaneously.

Also, I'm fine with flashing an alternate ROM with source available, such as CyanogenMod -- anything to get OTG + Charging working. Any advice is appreciated.

Thanks,

samwathegreat
[Moto G Q&A, Help & Troubleshooting] samwathegreat:
I was able to get your kernel to work! I can't thank you enough for compiling this kernel - it works PERFECTLY.

My device is a Boost Mobile Moto G on 4.4.4. I was able to unlock it, and flash the Retail US 4.4.2 system, along with your boot.img. I now have an [unofficial] Retail device with your OTG + Charging kernel.

I had no intentions of ever using this device as a phone -- but it's a bargain at $45 from wally world for some cool projects.

Mine is now serving as a full-time ham radio pan-adapter / spectrum scope using an RTL-SDR dongle connected to my HF radio's IF at 68.833 mhz. It works fantastic, and my power supply powers both the SDR dongle, *AND* the phone.

I made the cable as per your instructions, using a non-OTG cable.

If anyone is interested in replicating what I did, these steps must be performed in this EXACT sequence:

This ONLY applies to the Boost Mobile Moto G running Kit Kat 4.4.4. Also, I think it goes without saying, but don't do this if you plan on using your device as an actual phone. Also, this will wipe ALL data on your phone. Everyone has been warned.

1. Unlock the bootloader - free from Moto's website

2. If not already activated, ACTIVATE the phone. If you don't do this, the activation nag will never go away. You don't have to pay - just go through the steps at the boost activation website, and at the end select "I'll pay later". You don't need to enter credit card details. Make sure the phone actually activates BEFORE proceeding. Easy way to tell is to check SETTINGS > ABOUT PHONE > STATUS. If the phone shows it has an actual phone number, you are good to go.

3. Unzip the US Retail SBF 4.4.2 File. The file name should be: US_retail_XT1032_KXB20.9-1.8-1.4_CFC.xml.zip This is the ONLY ROM that is compatible with [MENTION=4830503]nlra[/MENTION] 's awesome OTG charging kernel.

4. Using mfastboot, issue the following commands to whatever directory you unzipped the files from the SBF to:

mfastboot flash boot boot_motog_KXB20.9-1.8-1.4_OTG_charge.img

mfastboot flash system system.img_sparsechunk1

mfastboot flash system system.img_sparsechunk2

mfastboot flash system system.img_sparsechunk3

mfastboot erase cache

mfastboot erase userdata

mfastboot reboot

Once rebooted (it will take a bit longer than normal), you will be booted into the 4.4.2 GSM (US Retail) Rom.

Failure to follow the exact sequence of steps will result in bootloops, or constant activation nags on every reboot.

This is perfect for SO MANY different uses using host mode. Possibilities are endless.

Thanks so much [MENTION=4830503]nlra[/MENTION]

If you send me your email address, I would like to donate.

I've noticed a loss of touch across the right edge of the screen, most noticable when playing candy crush and i want to switch on the far right, but in normal use it's absolutely fine, points to software in this case.

If you want to know if there are problems then download a multi touch app and move your finger across every inch of the screen, if you lose contact you'll know theres a problem and you'll have some tangible evidence when you take it back to the shop.

[Xperia Z1 Q&A, Help & Troubleshooting] jlevy73:
I agree, on a device this expensive it should defect free. I have the yellow screen issue but not the touch problem. The yellow screen is definitely annoying because no screen adjuster I have tried solves the problem. And when you compare it side by side with a N5 or HTC One, you really see just how bad the yellow hue makes the screen look.

Your case might be different since you have removed the ASF. So we don't know if you have the same problem as ours. You can check this through the multi touch tester and swipe your finger across the screen.

Mine produces skipped touches, this can be also tested in the calibration. Are you familiar with SGS touchscreen booster in play store? it has settings that adjusts the screen sensitivity but does not work on my z1. BTW those numbers that you have provided, does that mean that you have reduced the screen's sensitivity?
