[Q] Galaxy S4 as Carputer

I was thinking for some time to build myself a carputer, because I want to play 5.1 surround wav files in my car.
But that I discovered that the Galaxy S4 can output surround as well , so why bother about a carputer anymore if you have on in your pocket..
I was thinking about the following setups:
Galaxy S4>EAD-T10JDE AllShare Cast Wireless Hub>HDMI to optical converter> 5.1 amplifier
Or
Galaxy S4>Micro USB MHL to HDMI Cable adapter HDTV>HDMI to optical converter> 5.1 amplifier
Samsung chat confirmed that the wireless hub sends surround to the receiving device.
Any recommendations, or remarks? I'm still in a early stage. There are not a lot of car 5.1 amplifiers available, unfortunately. I have found one on ebay wth a toslink, but not with a direct HDMI input

[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?

4k no sound hdmi cable

1080 and 720 sound on but when switch to 4k no sound. If connect headphones sound on headphones but not on tv. TV is Techwood 40AO2USB 40" Smart 4K Ultra HD TV.

Not having sound on a fancy TV, that sucks. Did you try to swaps ports on the TV?
My MOJO was doing that while on 1020p. It worked when I switched with another hdmi input.

I tried all 4 ports

I connect Bluetooth speakers to get sound

HDMI ARC vs HDMI AUDIO OUT

In my tv no hdmi arc but support HDMI Audio out . what is the difference. And audio pass through missing after the update. Is any third party app for HDMI CEC for audio passthrough.

Are you saying your TV has a dedicated hdmi audio out? ARC stands for Audio Return Channel and it's the technology that can send audio through the same hdmi cable that is carrying video from a different source. In other words, you can pass video and audio to the tv, or the tv can pass audio back to the other device as well. This prevents the need from a second connection to pass audio from the TV when the TV is independently displaying content

Sony Android TV - USB audio support

I use a Sony KD-49XH8096 Android TV which, officially, supports the following audio signal output options:
- analog audio via 3.5 mm jack output
- digital audio via digital optical (Toslink) output
- digital audio via HDMI ARC/eARC output
The TV also has the following USB ports:
- USB 2.0 High Speed port
- USB 3.1 Super Speed port
I want to connect the TV to a Topping E50 DAC with built-in preamplifier, using the USB ports available on the Sony Android TV.
On the TV I enabled the developer mode and the "disable all audio routing to USB devices" option is disabled (as it should be).
If I connect the DAC to the TV USB 2.0 port, the audio signal is routed to the DAC, but the sound is full of "click and pop" artifacts. The volume can be controlled by the TV remote control inside the Android applications, but it can't be controlled by the TV remote control when in TV broadcast mode.
If I connect the DAC to the TV USB 3.1 port, the signal is routed to the DAC and the sound is perfectly rendered, without any "click and pop" artifacts. The volume can be controlled by the TV remote control inside the Android applications, but it can't be controlled by the TV remote control when in TV broadcast mode.
I opened a support case on Sony support Europe and their answer was as follows:
"Regarding your request, the TV has the possibility to play the sound through its built-in speakers, or through external devices connected to the TV via HDMI, optical or Bluetooth cable.
Functionality with other third-party devices, and with developer mode enabled, cannot be guaranteed. This is not normal use of the Sony device."
It seems that Sony don't endorse USB audio playback and don't care about offering or improving support for this capability, although the Android OS running on their TVs has the capability to work with USB audio devices.
I made the suggestion that Sony could and should improve support for class compliant USB audio devices (at least for stereo digital audio).
Sony answer was as follows:
"As you were told in one of the previous emails, the sound can be played on the TV speakers, or via external devices, but not via USB.
If you believe that your device has a defect, the only thing we can recommend is to have this device diagnosed by a repair center."
As you can see, Sony keeps to their policy and doesn't seem to care too much about offering or improving support for USB audio devices on their Android TVs.
