On CM7 I used dalingrin`s Nook Tweak app for boosting the weak volume output from the nook to the headphones. Since CM10 uses a different kernel, I assume this won't work. Are there any alternatives to fix this issue on CM10? I love Jellybean but need to be able to use my nook as an audio player.

I have been experiencing the same problem. However there is one exception to it... When somehow USB Host mode worked for me one single time - i played through USB audio and it was the same high level that i had experienced running CM7. I am unable to get USB Host mode working again. It's definitely in the CM10 kernel as it has worked once for me. Possibly the CM team is waiting to provide a Toggle in the User Interface for it. Should have one for Host mode and one for VBUS. Tools I used
Show USB host is active, but might be getting it from dmesg. I don't know where the locations of the stuff are to try to manually toggle it so i guess i will just wait until it comes in. If anyone knows a way to manually toggle the two please PM me.
i wanna learn how to make a kernel at this point...

Since the Nook Simple Touch does not have an audio jack, it's a deal breaker for me.
However, might there be some way to route audio via usb -> 1/8th TRS? If so, I would definitely jump on the device and buy it as soon as I get some money to spend on new toys.
Bluetooth maybe?
Well since the Nook Color hardware is so close to the N2E, since they have working bluetooth, I bet it won't be too long until we see the N2E with it as well.

Bluetooth is great, but it has quality issues. Is there any way to get audio straight out of USB?
would this soulve the ****ty audio hardware issues? my car offers USB bt and aux would USB do the trick?

I suppose giving our nook bluetooth would be without sense - why ebook reader would have it?

Well I believe the SoC includes Bluetooth hardware. Since it's there why not have that ability on the Nook as well. Enabling Bluetooth could solve general lack of audio issues for some people.
I thought I saw it somewhere that it's concluded Nook STR does NOT have function BT?
This week at Walmart I saw a USB / Bluetooth adapter. I believe you would need a micro-USB adapter to connect it to the Nook. But as I was looking at it, I was thinking of this thread and wondering if you could make the physical connections work, would the nook end up with Bluetooth capability.
Any thoughts on if this would work or not ?
not bleutooth ...
the thread seems to be going into bleutooth mode...
Was wondering if connectiing a headphone with a microusb adapter would help get the audio?
like say this micro usb to headphones adapter
www[dot]amazon[dot]com/Samsung-Headset-Adapter-Strive-Flight/dp/B003W057FS/ref=pd_cp_cps_1
same as catzilla this would really help me decide on the nook touch
People seem to get it working with the nook colour, so it may be for the touch as well.
First step is to get USB host mode
check this thread,

Saombra,
But this only works on CM7. Still waiting for something that may run on regular nook android. And it is quite scary that you may fry your usb on th enook in case you forget to switch it back to client mode before connecting to your computer.

Someone with a little patience could probably take the required code from the latest CM 2.6.29 kernel sources and apply it to the Nook kernel sources.
Also I seem to recall that the "usb power issue" was solved some time ago?
USB host mode is nice and all that, but are there actually any libs in Android that can push audio trough USB?
I remember dreaming of being able to connect my X10 to an external DAC, but that was before I invested in a couple of squeezeboxes
Well, I hope we can find someone with time and knowledge to do so.
And regarding the usb host, that is the information I found from saombra's post.
I don't know regarding library, but I know that in this post those guys learned how to get audio from a dock using a samsung smartphone usb port. So there is a way. Maybe the only way.
Hey guys, new to the Rooting community, but I would first off like to thank each and every person that has put time into these projects. The possibilities that have been unlocked on different devices has been enormous and its all thanks to the dev community.
I do however have a question, I recently took my NC and installed Ginger Bread and then Ice Cream Sandwich onto it with no troubles. However upon reading everything that has to do with Bluetooth Audio Input and USB Hosting, theres something that doesn't quite add up.
I can successfully connect to my Bluetooth headset with both the built in Bluetooth and a Rocket Fish dongle that I used through USB Hosting. However I get no audio input, I know that this is a known problem and it has to do with a possible lack of audio codecs and some other ideas that I have seen thrown around.
What doesn't add up though, is that when I connect my Logitech USB Microphone using USB Hosting it works perfect and gets picked up by every app. So my question is, what is the difference between the USB built in drivers and the Bluetooth driver that was unlocked?
From my understanding the Audio input file, driver or whatever it may be sits as a separate file. So with that in mind wouldn't that mean that the file exists, because the USB Microphone is using, so why exactly doesnt the Bluetooth connection pick up the Bluetooth ear piece as a microphone and refer it to the same audio input file?
Once again this is basically me spit balling and asking some questions. I was looking through the source code for the Nook Tablet (Trying to find its internal mic driver) and noticed that there was an audio C file and was wondering if that is what is being used by the USB devices to recognize Audio Input.
Anyways, any response would be great, one of the last tweaks that I would love to help get worked out as I planned on making myself a lovely Voice Control app to run on my Nook Color, and a Huge USB headset is rather illogical.

Since you're apparently asking a question about a Nook Tablet, not a Nook Color, you should probably redirect it to that forum.
Audio on Linux and therefore Android is a huge can of worms that even most developers can't figure out. Bluetooth is yet another very difficult library and has its own way of dealing with audio in and out. A2DP media audio out protocol has no audio in capability. As far as I know, no one has ever sorted out or enabled hands-free protocol for the NC, which is what it would take to do a headset with mic.
Hi there,
Sorry if this has been answered before, but I did a search an couldn't find anything.
Could anyone with the tablet tell me if USB audio out works with the nexus 7 into a USB DAC?
Thanks,
Paul
No, standard USB audio is currently not supported. A USB DAC made specifically for Android will be required as they use a non-standard implementation of USB audio.

*sigh*
Thanks for the info. Hopefully the device will be popular enough that iBasso or some other company can come up with a solution.

Super annoying huh. I tried my E7 and E17 since I seemed to be the first user of USB DACs to have a Nexus 7 in my hands and neither worked...
Maybe someone can pull the functionality from the GS3 and port it to CM10 for us to use. I can't imagine it would be too hard
Poitee has made a kernel which enables usb audio
http://rootzwiki.com/topic/30129-kernel-nexus-7-cifsnfsusb-otg-gpu-oc-cpu-oc-072912/
I have used it with my G930 headset. Unfortunately, its very picky about which roms it will work with.
I could get it working with aokp but not CM10, Jellybro, baked or glazed. You also have to have the headset plugged in when you boot.
So it is possible, all we have to do is get the kernel developers to include it.
For the moment i've gone back to Jellybro with trinity kernel, i like the speed
---------- Post added at 11:03 PM ---------- Previous post was at 10:29 PM ----------
I just found that usb audio works on my current config, all i had to do is reboot with the usb headset plugged in. The only problem is that the standard speaker doesn't work when you unplug your headset.
Running euroshank/jellybro rom with trinity kernel.
Yes, the kernel level functionality isn't actually that hard, and many kernels have it baked in even if the kernel dev doesn't realize it.
What really separates the GS3 from AOSP/CM10 is the OS level code that Samsung has added to allow hot plugging. Someone with knowledge of java could probably steal the changes from touchwhiz and incorporate them into CM10 with minimal effort.

When I plug in my G930 wireless headset into my 7 all the buttons work but audio/mic doesn't.
Is there any utilities to get usb audio working on this device? are there any roms here that supports usb audio?
Current running grouper rom and trinity kernel, any help appreciated.
USB audio needs a special hardware chip that we don't have.

I'm currently running on jellybro/trinity combination and my headset works if i plug it in before booting. So the hardware must be there, we only need more control with the software.
Stock no audio/mic but controls work well.

I tried to get mine stock to work. The controls work fine just the audio/mic dont do anything. I tried what you said to plug it in and boot up and it didnt work for me. but i am using stock non rooted. Any one get this working with stock yet?
Kitkat Stock rom on Galaxy Note 3 + usb otg cable + logitech g930!.
amazingly it works, with some notes:
-audio works (for music).. volume is a little to low. crank it up to maximum but still feel very low volume.
-voip call doesn't work (viber, line, etc)
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.
