HP ENVY Laptop PC 14-eb1000 (43P73AV)
Microsoft Windows 10 (64-bit)

I often use Cast desktop with Chromecast rather than my HDMI cable. 

 

On my new HP laptop, it mutes the sound by default. When I unmute the sound, it plays sound on both laptop and tv, with the lag between them giving an echo. Turning the sound down on the laptop turns the sound down on the tv as well.

 

I've searched the internet for solutions, and found that all the people having this problem are using HP laptops.

 

I've navigated to System > Sound > Volume mixer. On the right hand side, under Output device, there is a dropdown menu. It only has one choice, Speaker (Realtek(R) Audio).

 

Further down there is a section labeled Apps with a dropdown menu for output device. It only has one choice, default. Below that there are two entries, Google Chrome and VLC. They both have dropdown menus for Output device, and both only have one option, Default.

 

So there is nothing I can change.

That seems a bit odd, but a possible work around might be to plug in a headset or earphone to the laptop to cut off the speaker.  That you remove the echo problem.  Give that a try.

Hi, thanks for the suggestion but I tried it and it didn't work- When I plugged the headphones the audio kept coming from both the laptop and the TV.  I had to manually select the 'playback device' as "Heaphone" by clicking the speaker icon and then the drop down just above the volume slider. When I did that it restricted the audio to just the headphones.

That is an interesting happening.  Since you have already done some investigating on this phenomenon and did not find a solution, did anyone suggest a workaround that solved/minimized  the situation?

Has the Chromecast feature worked as expected except for the audio situation?  If this only happens to users with HP laptops, does the Google forum (if there is one) explain why this is happening?

Have you tried different laptop brands to see if that is true for yourself?

Of course using a HDMI cable to connect to the TV should stop the audio problem.  Have you tried that?  When connected with a HDMI cable, the audio can still be controlled (up and down) with the TV's volume control, and the audio coming from the laptop's speaker should cease.

Hi thanks for the reply.

 

The only other suggested workaround that I could find was the one I mentioned earlier about navigating to System > Sound > Volume mixer. Under Output device, the dropdown menu which only has one choice, Speaker (Realtek(R) Audio) plus the section labeled Apps with a dropdown menu for output device which only has one choice, default. Below that there are two entries, Google Chrome and VLC. They both have dropdown menus for Output device, but both only have one option, Default. So that suggestion wasn't of much help since there is nothing I can change.

 

Chromecast has in fact worked seamlessly when I "Cast tab". It is only when I try to "Cast screen" that I have this issue.

 

I have also been unable to find a Google forum on this subject of hp's issue.

 

I did in fact try casting my screen with my old laptop (Gateway brand purchased in 2012) and it in fact worked perfectly fine. There was no duplication of audio,  the audio only came from the tv.

 

And yes I was using an hdmi cable without any issues, but reverting back to that really defeats the whole purpose for my getting Chromecast in the first place.

I am sorry that I can not help any further.

Maybe someone else will see this thread that does know a solution.
