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?
Hi every wonderfull android devs !!
I'm a proud owner of the wonderfull (again) TF101, but i guess something usefull is missing in android mobility solution : i named : USB/PCI driver and player for TNT DVB-T TV Tuners under android
As now tablets and even phone have USB plugs and enough power to make it, maybe they can support those little USB TV tuner dongles.
As reference under windows i'm using pouchin TV which is a lite and fluid player for TNT TV (DVB-T - H264 codecs etc ...) but i know there are many more like this one and maybe some which could be better... BUT my guess is for android !! i fall in love with it, its not perfect but it tend to be a light and easy to use (and in same time powerfull and completly controlable and customizable).
(But if i can make a parenthesis i would say that android fully interface with windows and that's great but only few apps can fill the connectivity gap between androtablets and androphones (like pdanet for instance). So please think about functionnality between 2 android device in your apps devs
parenthesis closed . )
So what about my suggestion about a new kind of app for android : i mean TNT TV support (for mobility reasons) through mini antennas or wall antenna plugs?..
First : is it possible? (i guess most linux distro already did it)
second : will it be done one day? does some brave guys/grils with gold software coding hands would be brave enough to make it !?
Please respond to my hope!!!
Thank a lot for all the work already done and for the one that will be ! (in any topics )

Hi
First thanks for replies.
So if i have well read, froyo include the good drivers for usb tuners, but the transformer is under honeycomb (but that shouldn't be a trouble, as i guess that drivers would be included to it also) and the main trouble would be to adapt this app to the transformer (hardware point of view), it's just à guess as I'm just a Mc guyver with c code... And at least working on a rooted stock Rom..
Am i right?

I plugged in a cheap no name usb guitar interface and the rt picked it up as a usb input and audio device. I could not hear the output after trying a few settings but I was able to record it with a simple voice recording program I found in the store (toolbox). Believe it or not the audio latency was not too bad. Like I said I could not get the output to play simultaneously (probably too processor demanding) but it was encouraging that I could record it. I am a guitarist and one of the things I am hoping is for some good audio music production tools on the surface, which cannot be done on android due to latency issues. IPad owns the music production market currently so hopefully MS will be able to compete

EDIT: turns out WinRT automatically a Metro app for the MX892 ("Canon Inkjet Print Utility") that shows printer status (ink levels, etc.). Still no custom print settings (paper type, etc.), though.
Has anybody got a USB RTL8187-based Wi-Fi card that they can test?

Microsoft's site seems to take an "innocent until proven guilty" approach. The site lists my StarTech USB21000S as Windows RT compatible with "free download required."
Sure, it's recognized by Windows RT, but it needs a driver. Windows Update looks, but can't find anything. And, since Windows RT doesn't have any way of installing third-party drivers -- and StarTech doesn't pretend to offer any on its site -- it's incompatible.

Hmm interesting. The chip driving the StarTech USB21000S seems to be the ASIX AX88178, which has all manner of drivers available (including WinCE 5/6 on ARM), so I assume maybe ASIX made one for WinRT (hence the listing), but if it's not on Windows Update, then yeah, it's incompatible from a consumer standpoint.
Some items there seem a bit odd, like Intel's Mini-PCIe wifi cards, which are listed as compatible. I doubt 1) any WinRT machines (at least during MS' tightly-controlled launch phase) are going to use separate Wifi modules and 2) that WinRT users will be swapping said modules. So seems more like an internal component (of which tons are obviously not on the site).
Oh neat- just noticed that Surface automatically installed a Metro app for my Canon MX892 ("Canon Inkjet Print Utility") that shows printer status (ink levels, etc.). Still no custom print options (paper type, etc.), but cool nonetheless.
Dear All,
I have been using Asus OPlay Air, it has the following H/W specs:
Realtek 1073DD Features:
HD MPEG 1/2/4 & HD JPEG Decoder
HD H.264, VC1, RM/RMVB Decoder
AV Streaming/Transmission via Ethernet & WiFi

HDMI v1.3 1080P
I2S, SPDIF out
USB2.0 Host & PHY
USB2.0 Device & PHY
SATA
Fast Ethernet MAC & PHY
(from legitreviews)
Due to the quality of stock F/W, I have been looking for an alternate from day one.
There are lot of Android media players in the market with Realtek chipset: 1073DD, I am assuming that Android will run even on OPlay Air as well.
Can OPlay air actually run Android? Is there an Android Build for 1073DD Chipset? Requesting your guidance on this please.
Regards.

DIY Cable
WARNING: DO THIS AT YOUR OWN RISK. I AM NOT RESPONSIBLE IF YOU SHORT WIRES AND DAMAGE THE DEVICE/ACCESSORY
(Mods: Not sure where this fits - If necessary, you may move this post to Hardware hacking).
COMPONENT LIST
PL2303HX or FTDI USB to serial TTL cable WITH 3.3v supply - I also managed to get one from a Nokia CA-42 cable as shown here - but pretty hard to break the plastic shell encasing.
30-pin extension cable with at least 16 cords inside (not ones that just charge/sync) or Podsocket breakout
Aux audio cable. If from a headphone cable, be sure to burn off the coating as shown here.
Assorted sacrificial offerings of USB cables for their male plugs/female sockets.
USB OTG cable.
NOTES
I am not going to tell you how to solder and what equipment you need (Get a multimeter at least!!). I have never soldered or used a multimeter before this, so hardly an expert! Plenty of guides out there to help you in the learning process.
Pinout numbers may be reversed on the pod socket (see last column here).
Most of these extension cables have pinout numbers on both male/female end PCB and all the wires are color-coded.
You can pry open the plastic casing without breaking it..or you can break the male end and trace the pinouts to their respective colour-coded wires. Since I didn't want the 5-6 unused wires hanging loose, I preferred to rip everything out and solder only the essential wires directly to the female socket PCB.
Make sure USB to serial is 3.3v and NOT 5v.
30-pin extension cable manufacturers usually have the digital(1) and analog (audio) ground(2) pins shorted in order to scrimp on one lousy extra wire. But my untrained ear hasn't noticed any major interference. Minor interference I hear only when audio is paused is probably from the crappy LCD display on my el-cheapo tablet.
USB Y Cable isn't strictly necessary, but useful for devices that allow OTG charging.

HC-05 Bluetooth
HC-05 Bluetooth schematic for Hyundai Pre-2013 car audio
Since Hyundai schematic does not use 3.3v Accessory detect, HC-05 Bluetooth module connected to a USB cable can be used.
However, the HC-05 need to be configured with the AT command to the correct baud rate and the Bluetooth device name has to be changed to PodModeBT for it to work with PodMode app.
Please google for instructions on how to enable and run the AT commands on HC-05.
Code:
AT+NAME=PodModeBT
AT+UART=57600,0,0
We need only USB male plug (Shown as connector B above) to be wired to the HC-05 BT chip as shown below

Process to connect with PodMode app
1. First, pair the android device with PodModeBT bluetooth device in Settings>>Bluetooth. (Default pin is 1234)
2. Once pairing is successful, open PodMode app.
3. The app will try to connect and once connected, the status on PodMode screen will change to "Connected.."
4. Now you are good to go

Slight change in schematic - Moved USB Y Cable ground from pin 1 to 15/16. Note that these pins may be shorted on some of the extension cables anyway.
24/09/2013
Added support for FTDI FT311D Android Open Accessory USB host chip - Now, devices without OTG USB Host support can use PodMode in conjunction with FT311D ( http://www.ftdichip.com/Products/ICs/FT311D.html )

9/06/2014
Added support for Bluetooth HC05 chip.

No. Pin 12 of the 30-pin dock goes to the TX line of the USB to serial converter. I have fixed the schematic and added more pics for clarity.(Link to largest size pic)

I made it..It works. i'd prefer to use it with video playing are you working for others features?
Thank you
Great!! Can you tell me what car audio accessory and android phone you are using? Some pictures and video of the working app+hardware would be nice too
I have added a few new features:
* You can now choose a media app for playback in Advanced Remote Mode. Earlier the playback was restricted to media available on your phone and was played back within PodMode (you can still do this). Now you can play & control Pandora/Spotify etc in your car.
* Notifications - in Advanced Remote mode, if you get an sms or use Google Navigation, the sms/turn-by-turn direction text is displayed on your car audio's Track information (Album/song name) display for 15 seconds. .. Edit: Sneak peek pics below. You can display just about any notification like weather or stock info.
* Compatibility webpage - List of accessories and Android devices where this app is working (Information to be crowd sourced on when app is launched for the first time and successful connection is established with the accessory)
* App UI layout improvements - it looks better now (At least I think so! )

I haven't got much spare time to fully test the changes. I will try to upload the new version into Google Play as soon as possible.
Does the app only work with the custom cable??
Hi just bought a cable from cablejive.com called a samdock. its basically the same thing as the custom cable but without the audio jack. WIll the podmode app work with another cable or is it specifically designed for the diy cable above??
Hi. I have an Hyundai i20. I bought an usb-ttl interface from ebay but at the moment the item isn't arrived... So i open an old usb-rs232 interface with pl2303 and used it to connect to car usb
I can't put in links but search
modding-pl-2303-based-usb-to-rs-232
I used only gnd, tx and rx. No 5V to charge android tablet...
I used an xperia sola and Mediacom 810c modded with ICS.
I'd like to use with another tablet with gingerbread but it's impossibile .
When I'll receive the right adapter I'll made a compact cable and post some pics.

EDIT: The app currently uses some ICS API functions, so I can't change it right now to work with Gingerbread. I'll have a look when I have time (which is in short supply).

Short answer: No, samdock won't work with PodMode.
Long answer: I don't know what's inside the samdock cable, but I am guessing it has dedicated hardware to handle the serial protocol and passe-thru analog audio lines from the phone to the dock. My solution is different in that the serial protocol is handled by the app. So my cable design is just a "dumb" hardware.
Also, I don't think samdock cable will give you the remote control feature of controlling media playback on your phone from the speaker dock remote or car steering wheel controls. I know this because it is technically not possible to output both analog audio and usb signals at the same time via the micro-usb port on Samsung phones, even though S3/4 has 11 pin micro-usb
If there is sufficient interest, I may commercialise the hardware and sell it to people who can't DIY.

It is possible to control any media app as long as it handles Media buttons. i.e. you need to check if the app appears on the "Select app" list in app settings.

You can see Samsung video player on the list. However, many video players like Youtube, Vevo etc are not supported. Besides, I don't think it is safe to watch videos in the car
