[Q] Audio through HDMI?

This could be due to the ROM I'm using (Primee-P9 David's mod), but I tried using Rockplayer Lite to watch a video on my TV through HDMI and there was no Audio. Is there a setting I'm missing? Thanks in advance.

Perhaps there is a setting you are missing (I found rockplayer to be the most problematic player possible for the a500 with the exception of the crappy Acer apps that are preinstalled) - but HDMI carries audio and video only on receivers called HDMI switching or HDMI repeater, from my experience.
Try MX player, and if that fails, try a alternative receiver so we can figure out the source of your problem.

Thanks, I should've tried different apps to see if it was my tablet or the app. It won't be the problem of the receiver, as I'm plugging it straight into a TV :-D. Hoping its not an HDMI cable problem, I just got this cable from monoprice and I don't have another micro HDMI device to check it with. Thanks!

But it might be the problem of the receiver - your TV is acting as a decoder/receiver and depending on what company produced it and what standards it supports......
http://en.wikipedia.org/wiki/HDMI
Don't just assume a bad cable before trying a alternative receiver (TV) - plug it into a friends system with known good HDMI and see if that works.
Best of luck, hope you get it working

Well, I've used this HDMI port many times before and it works fine, which is why I was saying that the cable has a possibility of it being bad, but I'll try it on another TV as well just in case.

Always a good idea - that way you know for sure if you have a bad cable.

Stereo thru usb?

Hey guys so I got my phone hooked up to the car stereo via usb and was wondering is there an app or a settings I can do make my phone play music?

What kind of cable did you use for that? Did you use a mini USB to USB cable?

Yes exactly what I am using.
Also I am using the ICS roms (though unstable) and I heard that ICS is able to play music through usb. Correct me if I'm wrong

I'm unaware if ICS is able to run Audio through USB.
I've found in several another threads here on XDADev that it doesn't work even on the most recent phones and even on Jelly Bean (4.1, 4.2).
(One of those threads: http://forum.xda-developers.com/showthread.php?t=1771834)
Also, I'm just shooting at the big globe in the sky right now, but you could try mounting the SD card as a Massive Storage Device and letting the car stereo read the MP3 out the SD card. I can't try it on my radio, as it is CD-era old. Just saying.

FiiO E07K

Any one plugged an FiiO E07K into the USB port and can confirm the unit works with a 9505?
Would be interested in others thoughts/experiences..

have you asked the folks at head-fi.org?
I'd imagine you'd have a better chance there.

My Fiio E07k does't work (USB) with i9505.

I'm using the ATT i337 (nearly identical with the i9505) and it doesn't work with my Fiio E07k either.
My S3 works great with my E07K, so I'm a bit disappointed the S4 doesn't.
I've even tried a couple different roms without success.
If I connect my E07K to my S4 and try to play a music file, it fast forwards through the song/play timer in a couple seconds with no audio output.

Have you guys tried the USB Audio Recorder Pro app? Many DACs that don't work by default work via that app. Nowhere near as ideal as the native USB audio, since that app isn't designed to be a player, but if you got to have it that might be the only way.

Most of the posts I've read about USB Audio Recorder Pro mention that it only supports FLAC and possibly WAV files. I guess I could convert my ALAC files to FLAC though. Just hoping it's a kernel or driver issue that will eventually get sorted out.

Same issue with my Note II

Have you found an solution for this. I have experiencing the same issues with my Note II and E07K

No, I have not found a solution, but I'm hoping a custom kernel will eventually sort it out. It's obvious by the way songs FFWD when the E07K is plugged in that the phone "sees" the device, I would guess it just doesn't have the right kernel / usb drivers or configuration to use it properly.

I was also disappointed to find out my E07K doesn't work with the S4. Just got rid of my Note II as well. Any way we can move this forward? Using my headphones on the train just isn't the same!

[Q] Audio over USB with Android 5.0

I know there have been threads in the past about the Nexus 4 not being able to support outputting audio over USB, but now that stock Android 5.0 supports it, can the Nexus 4 do it?
I'm using the factory 5.0 images and I have an external DAC/amp that I want to use (Fiio e18) that's made for Android, but nothing seems to happen when I hook it up. I've read posts that the Nexus 4 physically can't output power over it's USB, which is fine because the DAC has it's own battery source... but can it at least output the audio?
I started with the stock kernel, but also tried the latest Franco kernel (r214) with no luck. Also, I verified the DAC itself works by using it with my laptop. I'm hoping there's just some hidden setting or patch I need to apply to get it to work... Has anyone else tried this yet?

pls report your findings if you can make it happened!!
i can not help you with your problem but it is something that interest me too. i only can suggest to use a more feature enabled kernel like unleashed or hells core
pls report your findings if you make it work mate!

That's a good idea... unfortunately no dice with the latest unleashed kernel either (98u). It claims it supports USB OTG, so I was hoping that would be enough, but maybe there's more that needs to be done.

one thing that you might not know. nexus 4 does support usb otg BUT cannot provide electricity via usb. you must use a y cable and provide external power so you it might not be possible to use your DAC!

Thanks, I did know that, but I figured that since my DAC is self-powered (it has its own battery) that I wouldn't need to do the y-cable trick.
Worth a try though, I'm going to order one and see if I can at least get regular USB OTG to work. Maybe once that's working it'll be easier to troubleshoot the audio.

Just wanted to update, I got the Y OTG cable so I could have external power at the same time... but still doesn't work. This is with stock 5.0.1 and unleashed 98u kernel. I went into Synapse and enabled the OTG setting as well. DAC doesn't get recognized, and I tried a few free apps that are supposed to do OTG checks, but they all came back that nothing is attached.

Usb otg is one thing and uab audio out is another. USB otg means that you can connect an USB stick or external hdd to your phone ( with or without external power) USB AUDIO OUT need special circuits from your internal Dac to the USB. If those are not implemented you will never have USB audio out. This is something witch depends on the manufacturer ( S4 mini with snapdragon 400 don't work with USB otg or USB audio out, htc mini 2 M8 works perfectly with fiio E18 as a audio surce for external DAC). So if you really need USB audio out please next time do your homework and read before buying a phone. P.S. Htc mini 2 M8 has the best audio ever and really you don't need an external dac. If you need more power just use your fiio as an amplifier with your phone.
Maybe you could find for your phone a apecial kernel modified for better audio experience. Flash that and use your headphones.
Good luck!

Thanks, yeah I don't need usb audio out... I've had the phone for over 2 years and I still really like it, so no plans on getting a new one just for this.
I believe it's physically possible to do audio out on the N4... I've seen random posts about people getting it to work, but they've all been on custom ROM's based on 4.4.x stuff. I'd really rather not try to reproduce that since 5.0 is running so much better on my phone, and I was just hoping with the new native Android support it might work out of the box. But alas, it looks like google locked down 5.0 on the N4 - even USB OTG storage doesn't work unless you put a custom kernel like unleashed on.
In the meantime, I've just been using it as a headphone amp like you suggest and it's a big improvement.

USB-C audio in 9.0 update

Hello y'all,
I recently discovered by accident that when I tried plugging in my PS4 controller through the USB-C port the phone was showing headphones icon in the status bar. And sure enough, the audio wasn't coming from the phone. So can anyone test this out since I don't have any USB-C headphones, but I always wanted them.
Thanks to anyone participating in this test.
Write your results here.

Audio through USB-C works at least since Android 8.1. I've USB-C mini DAC (Hidizs Sonata HD) and works perfectly. Also I tested Nobsound NS-10g USB input via USB host adapter and also works. So, isn't a new feature of 9.0 update, if you are thinking so.

I've been using fulla schiit 2, usb audio works on 8.1

Actually yes, I was thinking it's new because when I tried my friends USB C headphones it didn't respond.
But thank you for clarifying me! Your response is appreciated.

Does your Hidizs Sonata work also with Android Pie? I've just got Sonata II and it works only if I connect it within one minute after reboot. After that the phone ignores it and acts like nothing has been connected (but the phone is powering the dongle as I see increased draw in logcat and hear a very faint click in the headphones). So if I want to listen via Sonata, I must connect it first and reboot the phone, then it works perfectly. I tried all the available firmwares for Sonata, it does the same with all of them. With the PC or Huawei phone it works whenever I connect the dongle, so it most probably isn't faulty USB DAC, but rather something in the phone. Also I'm missing the option "Audio source" in the USB options in the phone's settings completely, if it makes any difference/sense.

Yes, my unit works perfectly with Android Pie, stock and custom ROM. What build are you using? Maybe something is corrupt

I'm no stock Android Pie, tried the adapter with February patch. Unfortunately adapter just stopped working with all of my devices (got really hot and then died completely), so can't verify with March update.
I'm going to visit an Apple store and try their USB-C - 3.5mm adapter, it is being said to be of a very high quality and is just 10USD/EUR and available locally, so I don't have to wait more than a month for delivery of another Hidizs from China.

Apple dongle behaves the same. Working when connected within ~1 minute after reboot, won't work on later (re)connection. I tried a different kernel to no avail. Would love to know why is it happening.
Edit: it happens that I'm forgetful, see explanation below

Oh my.. I'm stupid guys, I totally forgot that I configured recommended workaround "disable USB host" for 70000.USB wakelock couple of months ago. It was running one minute after boot via Tasker, no wonders I was experiencing this. Dongle works completely fine now (except of volume buttons on the Apple DAC). Sorry for stupid confusion.
