One thing that is disappointing to me is that the cc doesn't use CEC for volume control. It has it's own internal volume that is dependent on the current volume of the TV. I'm a little confused why it doesn't use CEC to turn the TV volume up and down. I realize that not every TV is CEC compatible, but I'm pretty sure the cc should be able to recognize when it is connected via CEC.
Maybe the hackers can figure something out now that they've gained full access to it
To add a bit more complexity to it here are a few other scenarios:
a) plugged into tv with receiver off = Would cec work by mimicing a receiver?
b) plugged into tv with receiver on = If one could control the actual volume of the tv via cec then they should be able to control the volume of the receiver?
c) plugged into receiver with receiver off = could mimic receiver and send volume commands ?
d) plugged into receiver with receiver on = would it work by sending the cec commands to the receiver or the tv which would then control the receiver?

I have two TVs, both with HDMI 1.4. I have read conflicting reports of power over HDMI with HDMI 1.4 being possible. Can anyone confirm this works, because I can't get it to?

my Vizio M551D which as 1.4a ports does not support power over hdmi.
As far as I know the only way to support power over HDMI is via like MHL, which the chromecast doesn't support.
I'm pretty sure any claim that said they were able to just power it via the hdmi port was BS
The Hdmi port does supply 50ma at 5vdc over pin 18. But from what I have seen on the chromecast pin 18 is not used or dead a small jumper wire going from this pin to a positive supply trace could in fact power the chromecast over hdmi as long as more then 50ma could be used. So this does not seem to be an option.
HDMI vs. MHL Power supply
Yes, HDMI has inherited some power supply requirements from DDC. It's 0,250W (5V * 50mA). This is unfortunately going in the wrong direction: From e.g. stick (if pin 18 is connected anyway, it's apparently not...) through HDMI to TV. This energy should be provided to power the internal EPROM of the TV. This intended for peripherals to read info about the HDMI-sink of the TV even when the TV is deeply sleeping. The spec even allows this 50mA to be reduced to 1mA when a session is initialized. Hence this is unuseable.
MHL has revered the power supply direction. This is now from TV to the Phone. This is inteded to power the phone. Unfotunately most TV sets at home don't have any or a proper MHL implementation available.
Hence a mass produced stick can't rely on that, and an additional USB power cable is mandatory.
Does this clarify the HDMI MHL power confusion a little?

Best topicson XDA! Fortunately with USB C HDMI will be outdated and replaced. Surprisingly I have not seen any TVs with USB C at this point.
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.
So I'm looking for a simple and efficient method for screencast/chromecast/similar for the Note to a spare PC monitoras video display.
I have a QI wireless stand for power, BT keyboard. mouse, speakers and a spare PC monitor with VGA and DVI inputs.. What I'd like to do is to simply set the Note down on the charging pad and have it connect to the BT peripherals and video out to the monitor.
I can manage the bulk of connection to the BT devices via Tasker, but what I need is a video solution with a chromecast device or similar to the monitor.
Suggestions?
Anyone know a way to stream any sound output over WiFi to a dongle I can ug into my slightly old reciever? Sort of like a blutooth dongle with output incan plug into my reciever.
Does this exist in a Bluetooth form?
Any ideas?
You look at Chromecast Audio?

Something like this would work

You just need to use an adapter like a left/right rca cable to a mini plug.

Hi. I'm installing a Nougat based Archos Core 70 tablet, with a DAB radio usb dongle in my car, but I'm having trouble sorting out the power scheme.
I can't get it to boot on car ignition due to problems editing fastboot in Mediatek phones/tablets like the Archos. So I've removed the battery and replaced it with 4.2v direct from the car battery, intending to have it sleep/wake on ignition through usb power.
However my otg usb hub wont register a usb power input while being able to run the DAB dongle. I don't need the input to charge, only to signal Tasker to sleep/wake the tablet.
Can Tasker take any other signals from usb apart from power? e.g. when some device is plugged in, or even a usb switch that outputs data instead of power. If needed I can add a relay to a usb input that closes on car ignition so it's as if I was physically plugging/unplugging a device.
Thanks.
