[Q] HDMI and speaker line out question

Hi to all
Has anyone tried the above?
Connecting the dock's HDMI to TV watch the picture in tv and try at this moment if speakers line out 3,5 jack had audio output signal? or it has no output and the sound is only going through the HDMI cable?
If anyone please has the dock, check this and give me the results.
Thanks in advance

The best conection for playing back Galaxy TAB video, picture and music files was,
GT with it USB cable on Mass Storage connection + TV with USB port & media play function.
The benefits from this conection was,
1. Single cable connection.
2. Only need connect GT to TV USB port, so less works & movements retriction between TV, couch/bed, power socket.
3. TV not only playback GT files but also provide power charging to GT. fter playback 1 hour of Full HD video, my GT battery power now up to 71% from initial around 50%+ (can't remeber the exact number).
4. Able to move around GT directory & playback files using one TV remote control. That's saving troubles of using 2 devices, GT screen + TV remote.

The thing is not a TV with USB, I have not a USB TV, I had used the dock in my Toshiba connected with HDMI cable and I have perfect video but NO SOUND at all, I had not found a solution yet, I had tried with several HDMI cables, still no sound.
I cannot find any settings for the HDMI, in the Tab.
Has anyone has any solution?
I had read that a lot of Galaxy Tab owners had HDMI sound problems.
The bad thing is when the TAB sees the HDMI connection mutes the sound in the tab and drives it through the HDMI cable.
The 3.5 Jack audio out in the back of the dock has no sound, when HDMI is connected
Any solution??

that's a really good question and makes a lot of sense. for the 2nd poster, I think almost all of us do not have usb inputs on our tvs. lucky you though
if the hdmi out sends pic + audio but the audio out is still available in the 1/8" adapter or another method then it would be really good.
would be amazing if the tab had digital audio out through a standards compliant consumer digital audio cable (rca or fibre) though
oh well, I'm dreaming right now.

[Q] MHL video and USB OTG at the same time?

I'm hacking a portable USB keyboard (from HP iPaq) to work on my note and planning on including USB hub, battery power pack, USB port for flash drive.
I'm also planning on adding HDMI out. I'll either include a switch to go between USB (keyboard etc) and video only or if I can have everything then this will become my "turn Note into a computer" all in one solution when plugged into HDMI monitor/television.
All the pins are there. But I don't know if MHL and USB can be used at the same time. Anyone know or do I have to try it and see what happens?
Blowing up my Note USB chip would not make my day! LOL

Sorry to rain on your ideas for the second time but not possible. Even if the logic were there to somehow implement both modes, there just is not enough bandwidth on those wires. You only have two twisted pairs and 1080P needs almost all that bandwidth to push enough ones and zeros to fill the screen at 25-30fps.
Your best bet for satisfying that fantasy is bluetooth keyboard and mouse. Think I saw a youtube video yesterday of a guy playing a game through MHL out while controlling through a bluetooth keyboard.

They are mutually exclusive connections at the hardware level, so no software mod can make this possible.
Bluetooth keyboard and mouse are great - check out my youtube channel "AndroidNZ" for a demo on MHL and various uses.

I was already impressed a while back by your video showing MHL video and so I went and bought a connector of my own on ebay
My main focus is to make a little do it all dock for sitting having lunch in a cafe. All built into a wired HP iPaq keyboard. I currently have a Dell Axim bluetooth keyboard and Logitech bluetooth mouse, but they aren't as smooth as I'd like. But the mouse is probably only useful when using a big screen.
So hardware hacking time!
But even if I can't do both, it will be nice to have my phone sitting next to the television with only a short HDMI lead and the phone doesn't flop around because of the stiffness of said HDMI cable as it does currently with my existing octopus setup of leads.
So it will have two modes.
Video mode where the keyboard only acts as a stand, battery pack and video port.
Cafe mode where I have keyboard with stand, USB flash drive, battery pack and USB.
All in a 15cm x 10cm x 2.5cm tidy expanding package :-D
Maybe when the Note 2 comes out with USB 3 we might be able to have both video and USB

oops, duplicate

MHL + OTG Multimedia dock is now available!
Heres the answer to your mhl + otg problem guys but a bit costly!
http://www.ebay.com/itm/Original-Sa...axy-Note-2-N7100-EDD-S20EWEGSTD-/230889526839

who can read is in advantage
this dock station is for the note II and not for the note I.
The pinout is different.
but 1 solution could be plugging in otg then usb hub then the micro usb female to usb A then the Mhl adaptor and the other connector of the hub with the mouse and the keyboard
http://de.focalprice.com/CA0352B/USB_A_Male_to_Micro_USB_Female_Adapter_Black.html
but finally i think it won´t work because there is not enoug voltage and power to get all devices so u need an external power supplier for the hub or an battery connect with the hub. try it out and tell us of your experience

MHL to VGA

Are there MHL to VGA adapters available that are know to work with the 4x?
Or is MHL standardized enough that i can pick any MHL to VGA without any worrying about working?
I know HDMI is usually better but my HMD (tac eye) takes only VGA or SVideo (though SVideo quality really suxx, its only on for NV not for data).
Also I see some MHL to VGA adapters have a secondary USB port, can this be used only as client or could I somehow connect a pointing device to my phone?

If I were you i would take MHL to HDMI cable and then HDMI to VGA. Reason is simple. Sometime you may want to connect your phone to new TV so you will need HDMI as it is standard port.
Secondary USB port is microUSB and it is used to charge phone while conected to TV (at least thats how it works with MHL to HDMI cable).

Well, for me this would than look like: MHL-HDMI adapter connected to a HDMI-VGA adapter connected to VGA-"Proprietary HMD Port" thats in used space and weight more for the adapters than for the phone and HMD. As i intent to wear this on my body thats rather not cool. Also the HDMI-VGA adapter will want some juice what will be an additional drain on my batteries.
The "VGA-"Proprietary HMD Port" is passive, so if I like the setup I will probably cut the MHL-VGA adapter open and attache the signal lanes directly to a fitting plug for my HMD.
Also I don't own a TV just a 30" WQXGA Dell Monitor with a Duallink DVI port its one of the old models that had only Duallink DVI, no scaling no DVI no VGA and no other ports.
An other issue would be how to control the phone when it in my pocket, how can I attache some pointing device and would this even work with android OS?
Or would I have to wait for an unlocked bootloader and this cool ubuntu on phone projects that provide a full ubuntu desktop?
PS: is the micro usb port on the adapter only used for charging or is there still a USB signal on it?

If i got you right, you want to control phone, connected to PC monitor, over HDM goggles?
You can try something like this https://code.google.com/p/androidscreencast/
It is a software that enables remote control of your phone over WiFi, so if your goggles work on PC it should work here to. It does the same job as the cable connection (MHL to VGA)
As for the MHL to VGA adapter you have 4 connectors:
1) male microUSB (one you connect to your phone)
2) female microUSB (charger or power supply, so it doesn't use phone battery)
3) female VGA (for monitor)
4) 3,5 audio jack for sound

Not exactly I don't want to use a PC at all. I want to connect the HMD (Vuzix-Tac-Eye-LT-Monocular) directly to the phone and use some pointing device or mini keyboard to control the phone.

I have the adapter and a problem,
the phone is only giving out its native screen resolution, my HMD cant handle.
How can I change the resolution so SVGA ?

Chromecast causing audio dropouts on receiver

Hi folks, I have my chromecast connected directly to my Denon avr 3310 and powered from the USB port on my TV. Chromecast is working as expected. I get dolby digital plus with no problems and great hd pictures from Netflix. Trouble happens when I switch back to my satellite box. That's connected to my TV via hdmi and receiver via optical. Since adding chromecast I get audio dropouts when watching satellite. How do I know it's chromecast? When I remove the USB cable powering the chromecast from the TV all audio issues dissappear. Anyone have similar issues? Cheers mick

I would do what was suggested and move the usb to maybe a wall adapter for power for troubleshooting. Also make sure that somehow your optical input is not assigned to the same source as your chromecast hdmi input and double check all your input assignments on the Denon.

Tried everything but in the end changed my satellite receiver to send audio via hdmi to the reciever and everything is playing nice now

Same here with a Denon 790 and analog sources. The Chromecast is plugged on back of the receiver inside a bookshelf nook, so disconnecting it is impractical.
The workaround is to drill down the menu through Input Assign > [HDMI] for the port used by Chromecast > set to "None". When using the Chromecast again, reverse the procedure and reassociate the port. Don't forget which port number holds the Chromecast.
It's inconvenient and my wife explicitly Does Not Like It, but the dropouts stop when you disassociate the port. You eventually memorize the remote key sequence without needing the onscreen menu.
Hope this helps, even after 3+ years.

Wireless deX?

I was wondering if it were possible to use a WiFi display dongle and Bluetooth keyboard and mouse with deX? I think the only issue is getting deX to launch when you connect to the wifi dongle. I want to be able to just set my phone on a wireless charger and (possibly set up Tasker to launch wifi, deX, Bluetooth, etc) use deX wirelessly, I am attempting to never have to hook up a cable to this phone, I haven't yet lol. ( I broke my last Samsung's charging port, RIP Note 5)

I think deX is a high bandwidth, zero latency affair. A wireless connection is unstable for it.
Maybe it can't work over wifi due to physical limitations. Wifi can have interruptions that may cause connection issues.
That's just my guess though.
