[Q] Why doesn’t chromecast output audio through TV's external speakers ?

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.

How to setup VR with External Surround Sound speakers?

I believe people use VR along with a Headphone/earphone, as well as they experience the VR through their 5.1 / 7.1 Surround speaker setups, atleast thats what i saw on youtube where people mentioned they get an immersive experience of the VR when you have the music coming from all the directions on their external speakers/soundbars.
So whats required for this. Currently am hooked up on a 7.1 channel home theater setup, Denon 4311CI AVR, HTPC (Home theater Personal computer) Chromecast, appleTV.. is this possible? Whats required?

Never mind i was able to figure this out.
Here is how its done..

You can also use bluetooth. My 5.1 theater system is kinda old with no bluetooth but I have a Bluetooth stereo adapter that works great plugged into my front external audio input jack.

Chromecast
if you turn on screen casting with chrome cast before plugging in your phone to the headset it will send audio to the tv. Its not perfect by any means and the video freezes right away but its a simple way to have more immersive sound.

Audio issue, please help

Hello to everybody, thanks for reading.
I will start with facts: on one hand, i have my desktop pc connected via hdmi to my tv, whose analog audio output is connected to my speakers. On the other hand, i also have a Chromecast 2 connected to the tv.
So in both cases, audio output is the same, BUT sounds different (and here's the issue).
For example, when i play anything (netflix, Spotify) through my computer, sound is fine, perfect. But when i do it via Chromecast through my android phone apps, sound is definitely worse: louder and a little bit distorted, like noisier.
I guess that the difference should be on Chromecast or phone audio driver (apparently working worse than pc drivers). But i don't even know if phone's audio is relevant here or not.
What do you think? What can i do? Thanks!

Do you have any other HDMI only devices to check the audio? Maybe there is something wrong in the TV with incoming audio on HDMI.

No, but i tried playing and sending Spotify to Chromecast through another phone, and i detected that sounded different than mine. So each phone's audio driver definitely made the difference by equalizing in different way. So I'm closer to conclude that problem may rely on my phones audio eq

That's so weird because from what I understand the chromecast works by receiving a stream URL and fetching the content itself. Your phones audio eq shouldn't matter.

Check the Apps to make sure they don't have any Audio Boosting features enabled.
Also try lowering the volume on the Apps to see if you can match the sound from the computer.
The Loudness and Distortion sounds to me like you are overdriving the HDMI input past what it should be.
Setting the volume lower should solve that and get rid of the distortion.

I have no issues with the chrome cast. I would check the connection on the TV or it maybe the chrome cast

Results will vary from device to device, TV to TV, App to App....Even from content to content.
Reasons why it can happen include:
Encoder/Transcoder used to create the content or stream boosted audio or failed to set levels to normalize it.
App (used to send the stream) has allowed volume control to boost low audio which would mean full volume on that App is much higher than +4 dBu expected by a digital device. This is done by App devs more for playback on speakers but that extra boost can distort the digital being sent to the CCast. Volume levels out of range will distort as the DSP doesn't know what to do with it. Remember the Device that launched the stream uses it's volume control to tell the CCast what level audio to send to the TV.
It can even be a simple matter of a dirty HDMI connection or bad handshake between the CCast and TV.
Both the CCast and the TV expect what we call a NOMINAL Level or (+4, -10 dBu depending on the TV model). This Level is supposed to allow enough headroom for louder sections to not distort while maintaining a decent range of quiet to loud.
If you go past this you are essentially cutting out whatever headroom exists and at some point everything gets distorted.
The solution is to lower the volume on the input (in this case the App sending the stream) and if needed raise it on the output (in this case the TV).
It may be counter to how Google expected and wanted the CCast system to work but it really is better (albeit less convenient) to control the volume on the TV as opposed to the App. Setting the App to full volume can easily lead to distortion.

Stream to Chromecast and Chromecast audio at the same time

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.

Is it possible to re-route sound output of AA to phone-car BT audio connection?

This is my setup:
Aftermarket head unit (IDCORE) connected through AUX to car stereo. AA is connected wireless (S10+, stock) with head unit; there is also car BT connected to mobile; when driving TWO active BT connections: 1, phone - car BT for audio and 2, IDCORE for AA).
And this is my problem:
AUX output (head unit -> car stereo) works, but has a quite annoying (static?) noise. Ground loop isolator is set, everything I can do hardware-wise is done -but the quality of AUX sound is MUCH LESS than it is when using BT phone-car connection (makes sense, Meridian built in system, with fiber optic).
Question:
considering above and that there IS an active phone-car BT audio connection during driving (beside the necessary AA-IDCORE connection) is there a way (software, app, switch?) to route AA sound through the phone-car BT audio connection, instead of the (noisy!) AUX wire?
Rooting of the phone is not an attractive option (due to my company account on the phone) - but I would be interested in any solution; as noise on the AUX output is quite disturbing. Thanks in advance

Have you checked the Bluetooth settings and checked music audio for the connection to the head unit?

Just did it. I CAN route music audio (in my case TuneIn) to BT in the settings of the phone (sounds, separate app sounds setting), but 1, this does not work (no sound over car BT from TuneIn, when using it on AA), 2, this setting can only be set for ONE application at the time (and I also use navigation, news service on AA), 3, the Android Auto app (the one I need?) does not show up in the application list of this setting. Still stuck.
My idea was (but I don't know if it is possible) a nifty app, that FORCES all sound (music, nav, news, etc) from the phone to BT (car), even when using AA.

I've got the same problem, using AA over USB and can't get Viper working because it doesn't stream over Bluetooth.

I have the same request. I have an AA unit attached to an original BMW X5 nav system. I can switch between them by long pressing the MENU button. The problem is that the AA unit can output sound only via audio jack and my car's system has fiber optics. The quality is very poor when compared. Is there anyway in which I can force my Android phone to output AA sound through car's BT? The AA unit has an option to do this for phone calls but unfortunatly not for regular sound (Spotify etc).

Anyone heard of anything related to this? I noticed that in the iPhones there is a setting in the accessibility options to route the audio through bluetooth. But there is nothing similar in AA. I can't believe this feature is not requested more.

Has anyone solved it? I'm struggling with the same thing.

I just ended up buying a BT transmitter which connects to my device's jack audio out and in turn it connects to the car's bt. It is stupid that there is no software solution to such a simple problem. Why can it do it for audio calls but not for music!? Why the iPhone can do it but the all configurable God of a mobile OSes simply can't?
Also, another idiotic thing of AA is that it doesn't allow you to switch the call to speaker or another bt device... in fact nothing happens when I get a call on the actual phone when connected to stupid AA. This is sooooo idiotic. Way to go android...

Aawireless also has a fewture that solves this also

Really? Where? What is it's name? Where do I access this?!

Aawireless: that is a piece of hardware again, isn't it (https://www.aawireless.io/)?
I look for an app/ software to solve this issue, if possible..

Aaahh I thought the reference was to Android Auto Wireless not a 3rd party hardware thing.
