Help plz for DSP connection via HDMI" - Android Head-Units

Hi guys,
I would like to connect an external DSP via the HDMI output and I want that any audio source from the HDMI go into the DSP.
So in your opinion, from the HDMI output on my Dasaita MAX 6 comes out any form of audio? For example, do you think that an Mp3 audio track (from USB stick) comes out from the HDMI output?
Thank you!

I'll explain:
Is it possible to play the audio mp3 track present on a USB stick and make them come out from the HDMI output?

[Q] HDMI + Sound output?

Hi Everyone,
I plugged my A7 through the HDMI port to my projector, it works with no issues whatsoever! But the sound jack doesn't work once the HDMI is plugged. Is there a way to force the sound to work even if HDMI is plugged in? Or even the speakers?
Thank you,
Marc
I have run into this issue with other devices, not the A7 yet though.
Once HDMI was connected the device only wanted to send audio over it and disabled all others.
My projector had RCA L/R out, but no internal speakers.
What I ended up having to do was get a RCA -> headphone jack adapter from Radio Shack and use regular PC speakers from that.
Probably not the solution you were looking for, but I hope it helps.
Possible solution
The option I'm looking at right now is an HDMI switch. It has 2 inputs for HDMI and outputs 4 HDMI and an RCA. I'm not really insterested in dishing out the 70$ for it though.

[Q] Nexus 4 audio over usb?

Does anybody know if it's possible for a mod/hack to be created that would allow for audio to stream over micro-usb/usb? Similar to iPhone..
Right now connecting the phone to car stereo via USB only reads stored audio, but can't play tune-in radio for example over the usb.
Audio currently cannot be directed over USB

USB digital audio output capabilities?

Hello folks
I'm considering buying a USB DAC/Headphone amp, the line in is USB. Does anybody know if the LG G2 has digital audio output from the usb interface by USB OTG? And up to what bitrate is supported?

[Q] USB DAC support?

Can I hook up an usb dac to the nexus player? I want to connect the nexus player through a quality USB DAC to my amplifier (which only has analog stereo inputs).
Currently I have a chromecast and use the headphone out jack of my TV to feed the amplifier, but this is less then ideal.
Would something like this do the job?

Yes, it might do the job. However, i read in the reviews that HMDI audio extractors can cause troubles with video sync and HDCP. Also, I want one with good audio quality. Most HDMI extractors are not reviewed by HIFI magazines.
So a good quality HDMI pass-through DAC reviewed by HIFI people start at $250,-, they are more expensive then their USB only counterparts of similar quality.
USB DACs are way more common. I can get a better quality USB DAC for $150,- (the ODAC by nwavguy)
I read that android 5.0 supports USB dacs (at least on mobile phones). Since the nexus player also has android 5.0, it should hopefully also support an USB DAC.
I'd like to do the same with my Icon Nuforce Dac, so I'm interested in the answer as well. thank you for the question.
Just an FYI that I am using an HDMI audio extractor with a Chromecast on a secondary TV. The TV (Sony) and receiver (Onkyo) are both 4 or 5 years old and were lower end units. Neither had pass-thru which was making me crazy until I figured out the problem (why no audio from the Chromecast)
I picked up one of the J-River (?) Extractors on Amazon. Reviews were mixed so I wasn't expecting much, but it works perfect. I plug the Chromecast into the extractor and run HDMI video and optical audio to my receiver. I've experienced no issues at all with audio out of sync and the sound is very good.
I am not an audiophile & not sure if this will help with your DAC question, but since I had good luck with splitting my audio/video via an extractor, I thought I'd mention it just in case.
I read that latest version of Android operating system for mobile (Lollipop) supports usb DACs.
Can we expect the operating system of the Android TV to support it as well?

[Q] Audio Specs? USB DAC Possible?

What are the audio specs of the nexus player? Does it support passthrough? Is there DD and DTS when you hook it up to your receiver? Also is it possible to use a USB DAC?
