[Q] Audio through HDMI?

This could be due to the ROM I'm using (Primee-P9 David's mod), but I tried using Rockplayer Lite to watch a video on my TV through HDMI and there was no Audio. Is there a setting I'm missing? Thanks in advance.

Perhaps there is a setting you are missing (I found rockplayer to be the most problematic player possible for the a500 with the exception of the crappy Acer apps that are preinstalled) - but HDMI carries audio and video only on receivers called HDMI switching or HDMI repeater, from my experience.
Try MX player, and if that fails, try a alternative receiver so we can figure out the source of your problem.

Thanks, I should've tried different apps to see if it was my tablet or the app. It won't be the problem of the receiver, as I'm plugging it straight into a TV :-D. Hoping its not an HDMI cable problem, I just got this cable from monoprice and I don't have another micro HDMI device to check it with. Thanks!

But it might be the problem of the receiver - your TV is acting as a decoder/receiver and depending on what company produced it and what standards it supports......
http://en.wikipedia.org/wiki/HDMI
Don't just assume a bad cable before trying a alternative receiver (TV) - plug it into a friends system with known good HDMI and see if that works.
Best of luck, hope you get it working

Well, I've used this HDMI port many times before and it works fine, which is why I was saying that the cable has a possibility of it being bad, but I'll try it on another TV as well just in case.

Always a good idea - that way you know for sure if you have a bad cable.

I'm using my Note to 'throw' photos and videos to my TV. It's great!

This is probably just a standard feature of android now, but I've just come across it recently after upgrading to a smart TV. It's just so easy now to watch my vids and photo slideshows at a whim on my 50" plasma. Another great use I've discovered for my Note.

How do you "throw" videos to your TV?

Using Allshare

Do you have a Samsung TV? The only way I know of to "throw" media via AllShare is with a Sammy TV or using the AllShare dongle connected to the TV.

So, let's try to understand this... I tried AllShare as a server on my PC, I thought it sucked to I installed Twonky instead.
Can I still get content "pushed" to my (older, Samsung) TV from the tablet?

My TV is a Panasonic 50GT50. I would assume this works on any `smart ` TV as long as it's dlna certified, so that should include all of em.
When looking at pics in my photo gallery I now have an extra button visible on screen because a dlna device is within reach. When I touch that, the photo I'm viewing appears on the TV in a few seconds.
It's the same with videos.
It's great for downloaded HD music videos from YouTube, or my photo slideshows I'm making in Windows movie maker (a great program).

Works well with a wdtv live.

It can also be thrown to an Xbox consoles that connected to the same Wireless network
As will you can watch youtube vedio from mobile to tv through youtube xbox application install it on xbox and pair your note with it and you will be able to watch the vedios on your mobile youtube on your larger LED

This is true. Dlna makes it possible. Works with my Samsung blueray player hooked to My LG t.v. I couldn't get the allshare thing working. Then I discovered the dlna way. Same thing really.

I gone to look see if this can be done with my ps3 I want that option......, lol

i use BubbleUpnp on my android and XBMC on a RaspberryPi to throw videos, music and Fotos to my TV.

If you happen to have a decent android phone with hdmi connection to tv, you can uses bubleupnp (both devices), to "throw" stuff and junk, if you dont have anything else.

With mirrop sender/mirrorop reciever app, you can do the equivalent of allsharecast(with lag), where your able to mirror your android devices, great for pics, vids, slow paced games etc etc etc...........ofcourse, ive not got my hdmi cable yet, so im assuming theirs no issues with connecting phone to tv, and mirror my note 10.1 to tv, via phone?

My t.v. doesn't have any wireless capabilities. It is an LG though. How I got it connected was through my Samsung blueray player. Which is connected Its wifi capable. But only if you plug in a wifi USB adapter. I have my router Ethernet plug plugged into the back of blueray. The Samsung player has dlna and that allshare cast. But I couldn't figure how to get allshare to work from the blueray end. So since I knew the player and the note had dlna capabilities, I played around with getting it connected. I previously had no experience using Dlna. All I knew that it was something having to do with connecting devices wirelessly or whatever.
How I got it connected? Well going into settings of blueray and in settings of the note. In your case it'll be TV settings where dlna option is at and your note. On your t.v., I'm guessing, as long as you have its wireless capabilities on or connected to your network, youngood to go on that side. On the note, you go into settings. Then more. Then in media share section press "Nearby devices/share your media with other devices" . In there, check the box that says File sharing. Depending on how much content you have saved in your note, it might take a minute or two to sync data. Then go into shared contents and make sure videos, music, and pictures box is checked. It might sync again if they weren't already checked. Then look in "allowed devices". You should see your t.v. name or whatever show up in there. I can't remember if I had to initially accept it or not. Checking the box will only bring up option to delete that device for me now. In my case, I see my blueray player name in there. In upload from other devices, I put "always allow".
Now once you have it set up on tablet side, you should be able to see the option or icon for your tablet appear on t.v. for me I have to press other devices on my blueray and ill see my tablet icon. I click on it and then they both connect. I can access all my video, music, or picture folders and view the contents. Kinda like an HDMI connection. Except dlna only lets you explore clthe content mentioned on the device only. It doesn't mirror everything like an HDMI connection. Like I can't access my apps nnor whatever. Only stored media content on device. Beware though when watching some downloaded movies. Some of these Movies have some kind of failsafe knowledge of knowing you watching a new downloaded movie. For example I have Argo downloaded. It'll let me watch it for a few Minutes. Then it'll stop and say device not authorized to watch this movie..lmfao it detects it by the device recognizing that the movie is in 5.1 Dolby or whatever. Since alot of the movies are screened versions or whatever. People on ps3 watching certain downloaded movies have same issue also. The only work around is reformatting the movie so it won't be detected. Its weird because I can play that movie on my note with no issue. I guess that only occurs when trying to watch it through a new t.v. or blueray player. It may even be built in, but I think its internet connection detects certain things in the movie and can tell that its a new movie that hasn't been released yet or on DVD and you trying to watch a downloaded digital version of it. Which is pretty smart. I can't be mad about that. Ill just watch those certain movies on my tablet which will play them regardless. Its not all downloaded movies. Only certain newer ones depending on what version you downloaded of it. Just a heads up. Experiment and see.
I also have an HDMI adapter for my note. It'll connect to this LG t.v. BUT for some reason the sound won't play through the t.v. or my home theatre setup. Its weird. I've read some t.v.'s be picky like that. I might try another HDMI cable to see if it makes any difference. Now I had another 39in. Flatscreen that I returned. As I didn't need it since I found a better deal on bigger one. But my HDMI played fine on it. Audio and video. Ill be OK though. It still connects the video to t.v. with no issue. So it'll mirror no problem. But when I play a game LR something through HDMI, the sound only comes out through the tablet itself. Doesn't come out the t.v. or theatre sound system. I wish my t.v. or pioneer system had a 3.5mm input jack for audio. As I would connect them that way, audio wise. That's how I connect my audio from my SG3 to my car stereo. I use a double sided 3.5mm male plug to plug them both up. My t.v. or pioneer doesn't have that jack. I haven't tried the coaxel method yet. But I'm not pressed about mirroring anymore. As long as I can access my media content, I'm good. I do miss being able to pull up crackle app and watch movies that way through HDMI. It ain't no good if the sound only coming out the tablet and movie picture on the t.v. lol don't want to watch movie that way. I'm looking for a bigger and newer t.v. so I'm sure my HDMI will work completely on it. But I can play games like Moddern Combat4 through HDMI and it plays fine on t.v. no lag or issues. Only thing is is that the sound to it only comes out my tablet SMH
Good luck getting yours connected. Let me know how it goes.

Thanx
It worked for me today.
Very nice.

I was able to successfully use the imediashare app. Very easy but why is allshare not playing nicely with the ps3? I'd love to use an app that I already have if I can. Anyone else have luck with allshare and ps3?
Sent from my GT-N8013 using xda premium

Maybe allshare is coded to work between Allshare enabled devices. Maybe they need to exchange a handshake code? Be good to get an allshare app for the ps3 and xbox.
I cannot get imediashare to hook up with the xbox though. In fact I can't get any thing to work with xbox.

How well does dlna allshare work when looking at a 1080p high profile movie?
If it is perfect for high profile movies I wonder why we can not mirror our tablet screen with dlna.

Use Nexus Player in Car?

So I was thinking I would like to use a nexus Player or raspberry pi in my car as my current cars music player is crap (I cant stream music through my Bluetooth)..So a couple questions for you smart guys. One my car uses rca for the aux screen input, if i use a HDTV Mini Composite 1080P HDMI to RCA Audio Video AV CVBS Adapter Converter would this play nice with the nexus screen size?
Also I have a nexus 5x can I use my phone as a hotspot tether for the player?
Thanks for the input guys

The NP will be able to run fine while tethered... I've used my G4 to give my NP internet access and watched 1080p movies just fine. The NP is just like any other android device in regards to connecting to an available WiFi network(in this case provided by your hotspot)
As for using a NP in a car setup rather than a Pi? I'm not sure you are going to enjoy either to be honest. I've tried some creative car audio/visual installs but learned it is not ideal(or safe) to rely on a remote for control. Touch/voice controlled configuration is best for day to day use.
As for will down-converting your digital video output to use with rca cables work?
Probably.... But the NP is still going to think its outputting digital, and you will surely experience some issues. The NP already has some over-scanning issues on older hdtv's. Not to mention the androidTV launcher isn't designed for a car sized display......
Just my 2 cents I guess. Try it and please report your experience with it:thumbup:

Thanks Bud...Not worried about safety I dont even look at my phone when I drive. Its more to have a decent media player for music and have google maps on display when I need it. My display is a 7" no touch....If I did a root and did something like a cm mod could I fix re-sizing issues with the display?
Thanks again
Just trying to find out options for my car with the crap oem nissan media

They are starting to make stereo's that will mirrorcast your phone... but that doesn't seem as fun lol. I'm not opposed to the NP as a car computer idea. You might want a small bluetooth keyboard with trackpad to use in conjunction as the remote.. or maybe not.

Cannot play Netflix with 4K @ 60hz for HDMI

I just switched to using a new TV over the weekend that's (finally!) 4k.
If it matters, the TV is the bleeding new Vizio P65-C1 also a good write up on the TV can be found here.
When I plug the Shield TV directly into the TV via HDMI and go to the Shield's settings then HDMI, it detects and shows (Recommended) next to 4K 60hz, which is what I set it to.
I can play YouTube 4K videos, I can watch anything I want without issue on Plex or Kodi, I can play all of my usual Shield exclusive games like Doom 3 or Portal without issue but for whatever reason, Netflix will just not play anything. Not just 4K/UHD content, just any content. I can move around through the Netflix menus and browse for what I want to watch without issue but when I try to actually play something it has no audio and freezes and might jump forward in broken increments or will be 100% frozen on the screen. I can stop it without issue and the app is otherwise responsive and not frozen.
I can Cast Netflix content to my Shield TV and it works without issue also. Correction, I cannot cast Netflix to the Shield TV. Same issues as trying to play locally. I was accidentally casting to my TV directly, which does work without issue. Both my TV and y Shield TV are hard wired to my router directly via ethernet.
It's only when I try using the Netflix app that is built-in.
The thing I noticed when I Cast vs the native app is it shows a loading progress screen and can take a few seconds depending on the contents quality to hit 100% then start playing. It seems like the native Netflix app is not trying to cache the content and seems like it's trying to direct stream it, which it cannot keep up with for some reason.
The same happens with cartoons, older shows that at best are available in 1080P like X-files or of course UHD/4K content. There is no different in the behavior between the different source videos in the native app.
I have already created a support request directly with Nvidia but wanted to see if others have encountered this as well and have any suggestions on what I can try to fix it?

Hey man... Finally got some sun in Atlanta?? What a nice day....
Anyways...see the link below I answered for somebody else, see it applies to you. They key is HDCP2.2 compatible equipment all along your video signal, Shield (which is), receiver, TV input. If any isn't, it won't work.

It was a beautiful pollen coated day today
I checked and sure enough the TV does support HDCP2.2. Though it also notes that while it's HDMI 2.0, it's not enabled yet and will be coming soon in a firmware upgrade. Makes me wonder if that'll fix this once it's available.
I'm still going back and forth with Nvidia as well but so far nothing other than answering some questions and sending them some logs.

From your TV user manual:
When connecting a HDMI 2.0 device, HDMI Color Subsampling needs to be enabled to support 4K resolution at 60hz.

Statement not correct... It support HDMI 2.0 out of the box. It's the HDMI 2.0a support that will be coming via a firmware upgrade.

Ah, good catch. I'm not as up to date on the HDMI specs/standards these days.
I'm guessing then that HDCP2.2 should work out of the box though but will contact Vizio support to confirm.

Just curious...have you tried different HDMI inputs?
"The new P-Series models will include: four HDMI 2.0a/HDCP 2,2 inputs, plus one additional HDMI that handles 4k/60p at 4:2:0, although it is listed as HDMI 1.4, Vizio told us. The HDMI 2.0a inputs will allow the Vizio displays to connect to new Ultra HD Blu-ray players to stream 4K with HDR10 metadata, something earlier Vizio 4K UHDTVs have lacked"
Are you connected to that "one" input?

According to Vizio's support "The tv supports HDCP 2.2 on all HDMI ports" so I'm not sure. The manual does not detail specific ports at all for HDCP.

@reTARDIS I just bought the same TV and am seeing the same issue. I noticed that if I change the Audio setting for the show I'm watching from "English 5.1" to "English" the show streams correctly. I'm not sure why this is happening either.

Interesting find. I'll test that on mine this evening.

@oracleicom I just tried this and confirmed it works for me as well. I send an update to Nvidia with this info to see what they have to say. Thanks for the workaround. It's not perfect but will do for the short term.

I would make sure you have a HDMI 2.0 cable (18Gb/sec), that's the only one that supports 4K @ 60fps with 4:4:4 chroma (color).
Use a port on the tv that supports HDMI 2.0.

I am having the same issue with Nvidia Shield and and the same TV. I was so excited when I got it today. I can also make it go with changing it english from 5.1. I had the Shield hooked up to a previous Vizio 4k TV and there was no issue. I am talking to Vizio support now and they want to blame the Shield even though it works fine with their previous 4K TV.
I also tested with my Nexus Player and it has the same issue.

@reTARDIS Did you ever get a reply from anyone at Vizio or Nvidia? On mine, everything but Netflix works fine, so maybe it is something that Netflix can fix in their Android TV app.

Correction, both Google Play Movies & TV and Netflix have the issue. Nvidia is saying it is Vizio's issue and Vizio is saying it is Nvidia's issue. I pointed out the Nexus Player has the same issue with the new Vizio and they have not replied.

They've really not given any indication that they have a clear understanding on what is happening and every time I ask for an update, if they reply at all, it's just to say that they're still researching the issue.
They recently suggested that I test the following.
SHIELD TV HDMI out -> Vizio P65-C1 -> Vizio P65-C1 HDMI ARC to Pioneer SC-1522K
Initially, I didn't think this would work as I had thought TV's did not output anything via HDMI and could only input but after doing some further reading today into HDMI and ARC, I think it might work to output just audio from my TV via HDMI to the receiver using one of the HDMI ports that supports ARC but I have not yet tried this.
As a backup solution, I just ordered this USB to Optical audio adapter last night that others have said works with the Shield TV to output audio via USB to TOSLINK. The device includes a TOSLINK to SPDIF adapter. I plan on just using this to output SPDIF directly to my receiver to bypass the Vizio TV to see if this resolves the issue or not. I will update later once I've tested it out.
I'll report back my findings with both test.

Update: The same issue exist with the USB to SPDIF/Optical adapter straight into the SPDIF/Optical input on my receiver (bypassing the TV for audio).
I'm at a loss for what to try next and the issue has not gone away.

Update: I figured out how to make ARC via HDMI work from my TV to my receiver over the weekend and am now only using audio out for all devices connect to my TV via HDMI then out via the ARC HDMI port on my TV (HDMI 1) and into the ARC input on my Pioneer receiver. While audio works without issue for any connected device and the Shield TV in general, the same issue exist as before with 5.1 audio playback from Netflix on the Shield TV.
I also did a factory reset on my Shield TV this past weekend but sadly it didn't change/fix the issue which still persist.
I just cast to my TV now for Netflix and avoid using the Netflix app on the Shield TV.

Does anyone have experience with a device that will mirror this phones display to a TV without a WiFi network? I'm pretty sure Roku and Chromecast require network connectivity.

A Chromecast will work internally with the phones hotspot feature

Yes the Chromecast itself is what downloads the show you are watching. The phone is merely a remote telling the Chromecast what to do

Oh yeah... No I'm wanting the phone to be the physical streaming medium but I want the TV to basically mirror what would be on my display .. Say I was playing PUBG and wanted that to show up on the larger screen... Or if I was using the Netflix app on my phone and wanted the movie to show on the TV... Is there something that can do this?

Not to my knowledge as everything is pretty much over the internet now. Maybe streaming pubg, but definitely not Netflix.

Is there a USB type-c cable with an HDMI connector on the other end that would work or will the phone not output to an HDMI like that?

I hate the Chromecast because you MUST have the "middle man" aka Chromecast connected to the Internet for it to work. It's so stupid. You can't just use a router, nope they make it where you must have internet access even to mirror to the thing. It's so stupid.
Rant over...but you can get mirrorcast HDMI dongles on wish cheap, and probably cheaply made. They also sell CC clones that don't have to be connected to the network to mirror

These are also on wish. I'm sure you can find much better quality ones on eBay or Amazon though

I wondered if this will do the job?? I just don't know if the phone outputs video data through its USB-c port

Alright I think I figured it out... If a TV has MHL built into it's HDMI port then it is good to connect a phone to with just a USB-c to HDMI adapter... However MHL needs a power source apparently and MHL seems to be a requirement to convert mobile signal to HDMI apparently. So if MHL is not built into the TV you actually have to have an MHL compatible adapter which connects to a power source to enable the USB-c to HDMI connection.
