Hi.. Hoping someone may be able to help. I have an lg TV that has sound distortion when using a chromcast. I get buzzing every time someone talks or there is a noise. Sound is very fuzzy. Tried extension cable to move chromecast away from the TV. Tried differing sockets and being close to the router. Doesn't matter what app or what stream it always has the sound issue

Hi Guys.
I've searched for an answer to this problem but no success. So sorry if it's been dealt with before.
I've recently received my chromecast and excitedly set it up in my bedroom. Everything seemed to be going great until I tried to cast a film. The video is fine but the sound is really high pitched noise. The noise does change when people talk or music is playing so the sound is getting through. This happens with videos through youtube as well.
My TV is just a cheap Elonex 32" LCD and I've had it a few years so I thought it might be the HDMI port that was faulty. I hoovered out the port and blowed it out with air but no joy. So I tried the Chromecast downstairs on my Sony TV. It worked completely fine. So I thought I'd try my Android dongle RK3188 from downstairs on my TV upstairs and that worked fine??? So ruled out the HDMI port being faulty.
So what is causing this high pitched audio through the chromecast upstairs???
Many thanks for any help :good:

Is the file you are trying to play have Dolby Surround Audio like DTS or AC3?
I have heard the same thing whenever I am playing on a Monitor that does not have a good Stereo Mixdown of Surround to Stereo.
Yes, it's not the port per-se, but rather the audio capabilities of your TV. Some TVs don't default to denying everything and instead go with "umm, I'll try..." which leads to devices feeding it something it can't properly handle and sad users. Same goes with resolution - a few TVs say they'll try to show 1080p then fail miserably, leaving the user with a black screen or "invalid signal" message.
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.
I've had a search but cannot find an answer to this, when I listen to headphones using the supplied dongle, the sound is very recessed, the vocals are barely audible, I have changed the audio settings to atmos on etc and different eq but still the same. I read someone say they had to insert the dongle the other way up, I did that and the sound was OK then, however when I tried it again later the sound was rubbish again no matter which way I inserted the dongle. It on the odd occasion will sound fine but 95% of the time is rubbish when I try it.
I tried different music players to see if any difference, iplayer radio is always bad, other apps are where I have heard the music fine on the odd occasion.
I then bought the Google USB-C adaptor, tried that, when that is plugged in I always get a clicking sound for a few seconds, the sound is always rubbish with that too, very faint vocals again, no matter which way the dongle is inserted. When I use that the phone defaults it to charge USB device, I have changed the options to all the others (charge only, transfer files etc) still sounds the same.
When I use the supplied USB headphones the sound is fine, no issues at all on all the apps tried. Bluetooth audio is fine when I have tried that as well.
Is there anyway to fix this? The phone hasn't been rooted and doing software updates has made no difference.
Does anyone else have bluetooth audio quality issues with their S10? When I connect my phone to my car bluetooth, the audio is crackly sounding, somewhat like a static sound. It seems to be with the bluetooth connection itself and not any particular app - phone calls, data calls, youtube videos, spotify, discord all for example suffer from this. I need to test a bit more but I think it happens on my bluetooth headset too, but it's harder to tell because it's a cheap headset to begin with. However, the car issue does NOT happen with any other device I use, so it isn't something to do with my car.
Nobody?
I have same issue, tested with an iphone and quality is normal

It started happen to me since last software update. s10+
I was testing a Bluetooth headphones using some youtube clips, I noticed that there is no left and right audio channels, the audio was coming from both sides, I used the cable instead of Bluetooth and it was the same, I tried lessening to the clip on my PC using the same headphone and the experience is completely different.
Anyone faced the same issue??? I tried another set and it was the same thing
The clips I used to test the headphones from youtube (I can't post the urls, just search for the title)
Check your Earphones/Headphone Sound Quality with 7D Virtual Expirience
#Stereo: Left and Right Stereo Sound Test
I checked and on my device everything works fine, left and right channels separately just as they should be.
You might want to check if you have Mono Sound turned on in Accessibility settings.
If no, then I don't know what might be the cause.
