did you see this
you can it at settings.
but it doesn't work at me .
maybe you can try it with your cables
I think HD2 can't use this software because it doesn't support TV out.
I want TV-IN....
I have a Android pad running 2.1 and it has 2 x USB ports and a lousy audio out (3.5 Jack).
I was wondering if USB soundcards work on Android? I am under the impression it is plug&play in linux, and that android uses the same audio driver? (just not via USB).
Beeing able to use a USB soundcard with propper sound would greatly improve sound quality (I want to use my pad in my car) :/
+1
I also want to know about USB sound cards support under Android. I have SB Live 24 (USB) and it works with my ARM-based Asus Wi-Fi router, but what about Android 2.2 and MIDs with USB-host port? ;-)
Anyone tried it?
It could be possible
Any update on this thread, would like to get this for my asus transformer if anyone can confirm it works. http://www.asus.com/Multimedia/Audio_Cards/Xonar_U3/#overview
It could be possible!
I tray it on acer iconia tab a500 and noting happend.
It not working.
It maybe need a driver but i don't see any driver anywere
:-(
USB audio in Android progress
Just for note, it works! I recently added self-compiled snd-usb-audio modules to allwinner based tablet. Found corresponding /dev/snd/* devices. Hard part is to add switch to USB audio to java, if there are no full alsa support in ROM. If alsa used, I need only edit /etc/asound.conf ;-)

could you give some more details on how this was done?
USB OTG gets mouse/keyboard/mass storage working, but USB soundcard doesn't get sound through it (though the card is receiving power) and I cant see a way to check if it can see the device.
the USB soundcard I'm using was seen by my linux pc (kernel 3.0.0-15) straight away no drivers or config needed.
Here is a what I found on USB AUDIO output with Android (maybe it makes sense to put and update this table to the first topic)
NOTE: as of now SOME (not all!) USB AUDIO Android support implementations stream data through Android MUX that disturbs the original PCM stream for changing volume which means re-sampling original media, but also limited to 44.1kHz(some 48) 16 bit, so for SOME Android:
1) max all your volume controls while using external DAC
2) there is no reason to have / use DAC with higher rates then 44.1/16
3) there is no reason to have / use files of more then 44.1/16 quality. Trying to play 96kHz 24bit file will result in forcing Android to re-sample it on the fly with limited resources and not perfect algorithms leading to degrading output quality lower then proper done in studio or desktop 44.1/16!
There might be a way bypassing the Android layer and going right to ALSA you can do 24 bit.
If you specify a hardware device ("hw:0") in ALSA you can bypass any potential sample conversions.
*there is way around it in linux ALSA http://blog.agdunn.net/?p=434 but i have not seen such for Android

please reply here if you find more info on DAC/devices suppot so i'll keep this post up to date.
I use either a C-Media $5 USB adaptor or a Lexicon Alpha 24 bit adaptor on my Nook Touch.
By bypassing the Android layer and going right to ALSA I can do 24 bit field recording.

why you are sure that it is 24 bit coming out of Nook Touch tablet?
what ROM / kernel you are using?
where you specify a hardware device? this should be done editing config file or there is a menu items in settings interface?
I'm sure that it's 24 bit because I can look at the file and see that all the bits are exercised.
Moreover, since the microphone only hits about -30dBFS, I have to crank the gain.
Compared to a 16 bit recording (which is effectively 11 bits when using 30 dB gain), the 24 bits (effectively 19 bits) sounds much better.
The Nook doesn't have any builtin audio, except for Dummy which is hw:0
My application uses hw:1
There's really no need to select the audio adapter because there is usually just the one.

I am a bit confused.
can you explain step by step how to archive it on stock NOOK touch?
1)install custom ROM with kernel and USB host support?
2)install specific media player? which one do you use?
3)plug in USB DAC, player will use it as output by default so no hw:0 tweaking needed?
The whole USB host mode on Nook Touch is covered here.
You will need a modified kernel.
The stock mediaplayer works but there is an unresolved bug that you need a little utility app to get over.
You need to put in an asound.conf

So putting asound.conf from the thread you'd mention will solve it and it will be transparent output 24bit 96khz?
can I use other media player such as Astro or PoweAMP?
The Android layer only supports 16 bits.
The MediaPlayer can not play 24 bit files.
To do anything 24 bit you need an external USB adaptor that supports it and an application that directly uses ALSA.
I believe that there are other 24 bit apps on the market.
24 bit is really only useful for recording when there is a large dynamic range.

I think we are talking about different use-cases.
My question was on plugging external 24bit/96kHz capable DAC (not ADC) to Android device and playing high quality 16bit/44.1 and higher .flac files using one of android players through that external DAC.
As i understand you've done it at least for 16bit DAC? and even mentioned that there is a way to bypass Android layer to get up to24 bit transparently out to the DAC and can highlight the steps for Nook Thouch to archive it.
Can you share your experience, settings and apps you've used?
Most USB adapters you will find are 16 bit.
To get 24 bit, you have to go to a "pro" interface, M-Audio, Lexicon, whatever.
ALSA supports 24 & 32 bits, but does not directly support MP3 or FLAC.
The Android layer supports MP3 (maybe FLAC?) playback, but not record.
You can get 24 bit playback just by using the ALSA utility aplay on PCM files only.
I do not know what there is on the market for 24 bit record/play.
You'd need an app with a JNI interface to the ALSA library.
I wrote a recording application for the Nook Touch that does that.
I cited it in the thread mentioned.

Just got stock Nook Simple Touch. Can you guide what steps to do to let it play music to external DAC?
I purchased an Android TV online and they said it had bluetooth support but it doesn't support it and they later told me there is no support.
Is there a way to add the bluetooth support for dongles into the already functioning android 4.2.2 operating system and add it in to the Settings menu so I can utilize it?
Hi!
I am planning to buy TASKER app in order to control my TV Android HDMI Dongle. But I'm not sure whether it will work or not? I would appreciate if anyone has some experience with this and inform me or guide me to relevant information source.
Thanks.
hi all,
i'm planing to buy an USB-C to HDMI Adapter to connect TV, but still don't know about supporting of Xiaomi mi mix2 with MHL.
Is it possible to show the smartphone's screen on TV and play videos with this adapter, anybody knows?
If no, are there alternative ways to get it (chrome cast and dlna are not a option)? May be with software?
thanks!
I went to a local best buy and tested out a USB C to HDMI dongle, unfortunately it did not work.
However using Chrome Cast to mirror the screen works great.
screen printing？
cable such as in 1990 ? use a chromecast or android tv with chromecast function

Is there a ROM where OTG functions work?
