Is it possible to run digital out from the nexus 9 into a mac for recording system audio at the highest possible quality. Don't really want to resort to use the headphone jack.
These are input specs and finally Android taking a step in the right direction.
From the Android Lollipop page:
"Lower latency audio input ensuring that music and communication applications that have strict delay requirements provide an amazing realtime experience"
"Multi-channel audio stream mixing means professional audio applications can now mix up to eight channels including 5.1 and 7.1 channels"
"USB Audio support means you can plug USB microphones, speakers, and a myriad of other USB audio devices like amplifiers and mixers into your Android device"

Ok, so I take it I would need an OTG cable, then would I run a usb cable from that into my mac or would I have to go via an audio interface?
Yup. See this:

Ok, last question. Is the Nexus 9 able to play music at a resolution of 24bit/96k? I ask because I understand that apple products are limited to 16bit/48k. Thanks

Hi guys,
After hours of web searches, forum trawling and experimentation, I have yet to find an answer to my question.
GOAL: To connect an old, Android bassed phone handset to an analogue amplifier and use it as a bluetooth passthrough gateway.
I have an old Sony Ericson X10 at my disposal which I would like to connect (via a 3.5mm jack to RCA) as a permanent fixture to my outdoor analogue amplifier and speaker setup. Ultimately, this phone would act as a bluetooth gateway to which other bluetooth source devices could connect and stream music stored on said source devices via this gateway to my audio setup.
The control and volume, as well as the media storage would be taken care of by the source devices and audio passed via bluetooth to the audio setup.
I have tried many apps available and have found none to do this basic task. If there is one available, or similar, I would love to hear about it!
Regards,
Jordan.
I’ve been looking a various solutions to stream music to a Hi-Fi such as Squeeze Box and Sonos, and am wondering if I could use my trusty old SGSI i9000 to stream from a NAS or other DLNA enabled device? I believe to Wolfson DAC is quite good for a phone, so I could connect the phone to the amp with a phono lead, but I also wonder if I could attached an external DAC via a USB adaptor to improve the sound output. I know this can be done on the S3 and some tablets, but not sure of the situation with other phones. I am ok with routing and custom ROM’s if that helps. Please note I do not want to play music stored on the phone, as my library is already 200gb and rising, but use it as a conduit to get the music from storage to the Hi-Fi

Hi,
You could try ArkMC app on Google play , it's streaming video by DLNA , it's well done
Regards
Hi Brya, thanks for making this your first post! The ArkMC app looks good. There are many DLNA streaming apps and this looks like one of the better ones.
My situation though is that if my Hi-Fi isn’t a DLNA device and only has phono input, can the phone stream a file from a NAS etc, play the file on the phone and output it through the headphone or micro USB socket to an amp. I think now that I’ve typed this out that the answer to this is yes.
So next question, how good is the audio quality going to be from such as set up? I think this depends on the DAC in the phone, which is quite good for a phone but probably not great compared to £300-£500 mini system. I’d welcome feedback on this.
Then the question is, can I connect an external DAC via the micro USB port?
For info, I haven’t actually got a Hi-Fi at the moment. I’m weighing up buying a mini system that includes a network streamer against more expensive and better sounding separates that do not (though they may have a USB input) and seeing if this would be a viable option for playing digital music.
Hello,
I'm trying to get higher quality audio input (sample width and conditioning, don't care about sampling rate above 32k) than is available through the microphone jack and was looking for an overview of where the development of such capabilites stands today. From what I gather:
Android 3.1 (maybe 3.2) added some support for USB Audio, though I can find almost no details on the capabilities. I can't post links, but a post on computeraudiophile with google search terms "usb audio enabled galaxy s3" claims support for a bunch of USB DACs on the Galaxy S3, but there is no mention of using the ADC.
Android 4.1 added support for USB audio docks -- these are generally (as far as I can find) speaker systems with a USB cable -- which only support audio output.
Software such as USB Audio Recorder Pro can record from a number of devices but this is of no use to a developer wishing to get the data into a separate application.
Lots of devices have HDMI ports but I found nothing about anyone managing HDMI input.
I can't find any such device for Bluetooth, but also nothing suggesting that it isn't possible. If so, can anyone speculate on audio quality limitations?
Now, I understand that the vast majority of users who want USB audio want output so it can go to their speakers, but there are some who need the other direction (or both...). Can anyone more familiar with the subject comment on the state of external audio input on Android devices?
Thanks,
Ben
Hello,
I am making navigation system out of my android tablet, and i faced a problem that not all times i connect USB DAC, android sends audio data to USB, but rather to internal speakers (some times it does that, sometimes it does not)
Is where a simple way how to set to use USB as main audio source, and block headphones or any other audio source ?
Same apply to FM radio, i can plug headphones so it would act as antenna, but i still need audio to be rooted to USB DAC
Small support via PayPal for some one who give me the right answer
I would like to know too
Hi All,
I have been searching about this topic for months I cannot find a method to use 6 channel usb dac or HDMI Audio output on Android. I dont want surround sound at all, but I would like to use my phone as the infotainment engine. However I should be able to route notification/phone audio to a specific channel lets say front left. I checked android hal service for related interfaces but configuration files doesnt really show clearly how can I implement this.
Are there any kind of example of this? Can you please advice me how can I do it. Even if I can manage to make one stereo pcm output for media + mono pcm output for notifications and calls that should be enough too. I can do the rest with a microcontroller.
One more question I heard few times androids audio mixer layer is so crappy that makes jitter on pcm signals, how is your experiences? For instance qualcomm based socs have integrated dsp why phone developers gets benefit from it?
Thanks
Hi, mbt28 did you manage to find a solution for this?
I'm searching for exactly the same solution, to somehow output digital stream (containing multiple audio tracks) to a DAC, which will then convert it to multiple analog tracks.

I've got multichannel analog output working on my H96 Max V58 tvbox, with a Startech 7.1 channel USB soundcard. It's got Android TV OS 12. I had to edit /vendor/etc/usb_audio_policy_configuration.xml to add the necessary info. I'm attaching a diff with my changes. The changes are just based on what I saw for the HDMI policy. I haven't tried to get the digital channels working on this device yet but that might be nice to try later too.
The reason I deleted some text from the header comment was to keep the overall filesize the same as the original. On my box /vendor is mounted from /dev/block/dm-1 and even though it's an ext4 filesystem, you can't edit any files on it because the FS has no free blocks left. So I had to overwrite the file by finding its byte offset in the block device image instead. If you can edit the policy file on your box, you can ignore that part of the diff.
PS: this is the USB soundcard I used https://www.amazon.com/StarTech-com-7-1-USB-Sound-Card/dp/B002LM0U2S
It works OK except its USB jack is flaky, doesn't always get a good connection. I have to jiggle the cable sometimes to get it to power on, but then it works.
PPS: I just checked, the SPDIF out works as-is, carrying the front left/right audio.
