i stream video from my laptop to my projector work fine but i have problem the sound! when i stream any video to chromecast on my computer have to sound of the video im playing!
is there the way to by pass this? stream video but also on pc still play audio of that video?
When you use a native Chromecast app for casting, it "hands off" the request to the Chromecast and the Chromecast itself goes and retrieves the data. Essentially the Chromecast itself plays the content, so the audio and video come out of it.
If you cast a tab or the entire desktop from a PC and don't enable the audio, it should play audio from the PC, but the audio and video probably be out of sync.
Otherwise you will have to "break out" the audio from the HDMI stream with an HDMI audio extractor (make sure it is HDCP compliant) or other converter, or route the Chromecast through a HDMI A/V receiver so it can play the audio.
I apologize. I was incorrect. When you cast a tab or the entire desktop, the Chrome extension somehow mutes the PC audio... which in your case would leave you with no audio at all.
So you'll have to "break out" the audio from the HDMI stream and get audio that way.

Something like the options in the ling below may be what you need.

But in the setup the audio would have to go from this "box" to your audio system.
Chrome cast to "Box"
"Box" to projector for video
"Box" to audio system for audio
I have read that other have used a similar set up to get video and Audio to a monitor that doesn't have a HDMI input. I don't know if sending the Video to the projector and the audio the the audio system would produce sync problems. One way to find out.
I don't see a way to get audio out from you laptop using the Chromecast.
Hope this helps
I was just watching a video on my TV with VLC player using cast entire screen and audio through my PC worked fine, just had to set an audio delay in VLC to get audio synced. I did this thru my bluetooth stereo adapter but I thought there was a minute before I setup the bluetooth that the audio worked through the PC speakers.

It's one of the following...
1 - You need to change settings on the TV to pass Audio or to Use External Speaker (setting vary from model to model so some hunting and pecking for correct settings is in order)
2 - You need to check your HDMI connection between the TV and the Speakers. HDMI-ARC (Audio Return Channel) usually works on only one input of the TV and it should be labeled as an ARC input. If thats correct then check settings (see #1)
3 - If you have an older TV that does not have ARC support you need to connect an Optical Cable from the Audio Out of the TV to the Amp. If you have that then again See #1!
Take note that EACH INPUT on a TV will have it's own Settings for Audio, CEC, and ARC so just setting the TV defaults may not be enough. Check to see if your Inputs have their own Audio/Speaker config settings.

Hi all,
First off, thanks for the help.
I'm trying to cast a local file from my PC to the TV in my living room. The video plays fine, but there is no audio stream to the TV. There is also no option to turn the audio on at all within the browser.
Any ideas what the issue or extension I need?
Thank you!

The Cast extension should automatically redirect audio to the Chromecast when casting a tab or the full screen.

Cast the entire desktop to see if you get no audio at all, audio on TV, audio on computer, or audio on both?
Play a second then pause it. You should be able to determine if you get audio from the PC and TV, because the PC playback will be immediate, while the TV playback will follow a second or two later.
I get audio on both[/]b PC and TV doing this.
Now, cast just the tab and do the same.
I get audio only on the TV doing this.

If you are trying to view a MKV file, it will not have audio at this point.
Here is my set-up:
A Vivo LTV42FHDN 42” Full HD TV (2x HDMI inputs, 1x RCA stereo audio output, few other audio and video input connectors, and a set of really crappy built-in speakers)
A Logitech 2.1 Speaker system connected to TV's RCA audio output
An old DELL XPS M1330 notebook running Windows 7 hooked up to the TV via one HDMI port
A new Chromecast I’m trying to setup connected to the other HDMI port.
When I watch TV and switch to the HDMI input of the PC I get audio through both the TV’s crappy built in speakers as well as the much better sounding Logitech Speakers. However, when I switch to the Chromecast I only hear audio through TV’s built-in speakers. I have connected other PCs and tablets through HDMI before and from what I recall, sound always came out external speakers.
Is there any reason for the PC and Chromecast to behave differently when connected via HDMI ? I tried both HDMI ports, went through TV's audio settings (which only has very few settings like bass, treble, and some sound profiles), but couldn't get the chromecast to output audio through external speakers.
Does this mean Chromecast doesn’t support somesort of an HDMI specification/standard my old PC does, therefore the TV can't split and reroute the audio ? Is there any way to get around this without buying new hardware ? Other than audio, rest of it works great ! For me spending $50 or so extra on additional hardware really defeats the purpose of buying a Chromecast, because for that price I could've bought a DLNA enabled media player.
Any help appreciated. Thanks.
I'm not sure about your LG, but my Sony correctly re-routes audio from Chromecast to SPDIF (optical) output connected to AVR, so the Chromecast isn't a problem. I'm not sure about analog RCA output though.
Just go through your TV settings again. There must be an option burried somewhere in menus.

Thanks for your reply, I did go through all the settings on the TV and even read the manual. But couldn't find anything there. Its not a very high-end TV, hence no optical output, all I have is that stereo analogue output.
Few minutes after posting I again connected my new notebook, and a Windows 8 tablet, audio works fine with all of them. But the Chromecast just doesn't work the same way. When I tested I connected all devices to the same HDMI port and didn't change anything on the TV, all I did was plug one in > test > unplug > plug the next one in > test etc.. that's all.. the fact that everything but the Chromecast work has to mean there is something different in Chromecast's HDMI signal.

Try switching the audio output in whatever application you're casting from to Stereo.
If Chromecast is sending multichannel audio, your TV might be smart enough to decode and play it on its speakers, but not smart enough to downmix to the analog output.

Hi,Were you able to resolve this problem? Chromecast works great except for this exact same annoying problem. Also have the same TV. Thanks.
I'm working on a multi-room audio system with both AirPlay and Chromecast as input sources. It utilizes forked-daapd and Shairport (for AirPlay input) running on a Raspberry Pi. For Chromecast, I'm using an (AGPtek® HDMI to HDMI + SPDIF + RCA L / R) audio extractor and (AFUNTA USB 6 Channel 5.1 Optical) USB sound card. I've written a small C program to capture the audio input and feed it to a pipe that forked-daapd can then play to AirPlay speakers throughout the house.
So far, it works with analog audio, but I can't get the S/PDIF capture to work. I've hooked the Chromecast and audio extractor to my Yamaha receiver over S/PDIF, and it works. The receiver displays "PCM" and plays 2-channel stereo. I've also run S/PDIF out of my Windows 7 PC to the USB sound card, and I am able to capture that audio with no problem.
What could be different between the S/PDIF stream from the Chromecast/audio extractor and the S/PDIF stream from my PC?
I'm still struggling with this. Could there be copy-protection that is surviving the audio extractor and preventing capture?
Chromecast audio now has multiroom support. I would like to figure out a way to add chromecast (video) to my audio group. Currently google says it's unsupported, but hoping for a work around. Like maybe have my chromecast "look" like its a chromecast audio to the app?
Any help is appreciated.
What would also be cool is if I could cast video to chromecast and audio from that video to chromecast audio. But this is a lot more difficult.

Here is a workaround for simulating 5.1 sound with Chromecast audio. Say, for example, you want an approximation of 5.1 sound for your home theater but you don't want to have wires connecting your 2 surround speakers to your receiver. For example, you don't want the speaker wires cluttering up your living room and you don't want to run them through the attic. Here is what you can do: buy 3 Chromecast audios for about $35 each. Buy two small amps for your surround speakers. For example, the Pyle 200 amps cost around $26 each. These small amplifiers will change your surround speakers from passive to active. One Chromecast audio device should be connected to your main receiver . Attach the 2 remaining chromecast audios to your Pyle amplifiers connected to the surround speakers. Each Pyle amplifier can actually run 2 speakers, but for this example we are using one amplifier for each of the surround speakers to minimize wire clutter. Short speaker wires will need to run between each of the Pyle amplifiers and and its surround speaker These speaker wires should be attached to the appropriate terminals (left or right) of the 2 amplifiers. In the Google Home app, first add all 3 devices. Then create a speaker group that includes all 3 devices. For example, we will call the new group MySimulated5.1. Attach your laptop, tablet, or phone to your TV HDMI-in by cable. Cast the audio to the MySimulated5.1. Be sure built-in TV speakers are off so that all sound comes from your external speakers.
This system will work because you are not casting to both Chromecast and Chromecast Audio. Your video will have HDMI quality. to the extent it is supported by the source device. You can use Microsoft Dolby 5.1 test on YouTube to verify that all your speakers are working. If everything is set up correctly, your left front speaker will play audio intended for left front and left surround. Center speaker will function as usual. Right front speaker will play audio intended for right front and right surround. Everything played on right front and left front will also play on right surround and left surround speakers, respectively. The system will not be true 5.1. However, the surround speakers will reinforce lateralization of audio and improve immersion.
Does anyone know of a single input, single set of outputs, 5.1 Dolby Digital/DTS decoder that actually works with the Chromecast?
I'm using a Chromecast in an outdoor theater setup, with it plugged into this "extractor":
http://a.co/d/7m2UFHS
with the extractor's HDMI output plugged into a projector HDMI input. I have the extractor's front L/R, center, surround L/R RCA outputs running to an amp, with the amp's outputs connected to the five speakers.
Trouble is, the extractor doesn't actually appear to do anything to produce audio going out the center or surround outputs. I assumed it decoded the DD/DTS audio signal so the 5 channels would be separated into the corresponding RCA outputs. Otherwise, I have no idea how those outputs can ever get sound going out of them.
My two uses for the chromecast are Netflix and casting video files from my computer via VLC player. The files are mostly mkv with 5.1 AC3 audio.
