Windows 10: Laptop HDMI to TV: video but no audio

    Laptop HDMI to TV: video but no audio

    Okay. I'm having one heck of a time trying to get this thing to work. I recently purchased a new Asus laptop running Windows 10. I have it plugged in to an HDMI switcher which, in turn, runs to my TV. Now the problem is I am getting no audio from my TV speakers, but the video is perfect. I know it's not any of my HDMI cables because I plugged in my older laptop and that works perfect. And I know it's not the switcher. I also tried to right click on my audio device manager and it says nothing about my TV or HDMI being the default audio player. I've also checked on "Show Disabled Devices" and "Show Disconnected Devices." I've downloaded the AMD Catalyst but that didn't seem to do anything. I am completely stumped. My other laptop was working flawlessly as soon as I plugged it in. Any advice would be wonderful.

    The new laptop may use a newer version of HDMI eg 1.4 , while the old one used 1.2 and you may need new cables if going to a higher resolution eg 4K which the old cable don't support too .

    take the HDMI switcher out and try it direct too , incase it is it , that cant handle a newer version of HDMI

    Okay. So I tried a number of things. I ran the HDMI directly to the TV and it worked fine, so perhaps it's not the cable? Although for one reason or another, I need to utilize the switcher, and for some reason my laptop simply won't recognize it as an audio source. It's gotta be something on the laptop. I even pulled out an old crappy switcher is used to use, and with that I was able to get audio and video, but there was quite a noticeable delay with both.

    I'm no expert on this stuff , sounds like the Switcher is the issue to me if not recognized, perhaps see if the Manufacturer has a Firmware update or anything for it perhaps ,check their FAQ too..

    It's just weird that the switcher will work with one laptop but not the other. I'll keep digging. Thanks for the input.

    I am guessing (again :) ) that it is a HDMI version issue , I have seen similar issues with DisplayPort 1.1 and 1.2 , I think HDMI 1.4 needs different cables to be capable of hi resolutions (4k) for eg. but I am not sure why your audio is now not working.

    Hi there

    Check Audio settings on computer - you might still have it set to Analog / phones etc.
    You can easily test that - try connecting headphones to the socket and see (hear !!) if there's any audio.

    You've tested the switcher I assume - swapped the laptops around.

    Incidentally quite a nice cheap piece of kit is an Audio splitter - it's a standard HDMI cable with L and R audio output as well. The slightly more expensive ones have Digital (Optical) audio output too. Often 5.1/7.1 as well. Great if you have better sound systems than the standard fairly cheap desktop speakers.

    OK not a solution to your current problem but I thought I'd mention it as it's a useful piece of kit - a lot have never heard of this type of stuff.

    For multi-media I'd suggest also using VLC as it has zero problems with almost any video / audio codec thrown at it.

    Also not a solution to your problem - but saves loads of cables etc -- for multi-media on your TV try using something like PLEX media server (free) on the computer(s) - it's free. If you don't have a smart TV then a google chromecast device works brilliantly.
    The advantage of using a server is that you can easily switch on the TV to the computer you want serving the video you want to watch (or the audio if music). So mch better than messy cables and switch boxes. Again just a suggestion - I know it doesn't solve the problem but IMO this is a much neater, cleaner and more elegant solution to the problem - YMMV of course. Just to note --the PLEX server(s) are controlled by using a smart phone (Free PLEX app) so it's really easy on the remote TV. !!
