HDMI Audio Help

[squibby171]

Someone suggested I posted this here in case someone had some ideas.

I've been combing through the internet for a couple weeks now trying to sort out this issue. I bought a new laptop, ROG GL503GE, and wanted to use it to play games on my TV (Samsung). My previous laptop everything worked fine for all the games but this one seems to have issues I cannot sort out. There are select games (e.g. Ultimate Chicken Horse and Jackbox) that run in full screen and push the audio through the HDMI to the TV perfectly. Other games will run in full screen but not push the audio (e.g. Terraria). And lastly some will run in full screen but play the audio only through the laptop speakers (e.g. the Lego games). I have tried uninstalling and reinstalling the drivers for the Intel Integrated graphics card (UHD 630) and the NVIDIA graphics card (GeForce GTX 1050 Ti), both the ones recommended by ASUS and the latest out there, and that did not work. I have tried setting the default audio to the TV with no luck. And I have also tried disabling the laptop speakers entirely and still no dice.

I suspect this is a driver issue but I've run out of ideas of things to try so if anyone has any ideas, I'm game to try something new because this bothers me that I can't play all my games through a TV. I ran DXDIAG and there were no issues reported.

If you need more specs or information just let me know. I really appreciate any help anyone can offer. Thanks!

Have you set HDMI audio to PCM?

[squibby171]

TV was Bitstream. Switching to PCM did not fix the issue (restarted Steam after the change just to make sure).

I meant on your laptop...

Presuming I did it correctly, that did not fix it. Though the only instructions I could find were to uncheck the allow exclusive use box option so if that isn't it then I may need some pointers.

Have you tried Open Sound setting? It should be sound out to your TV.

Right click on speaker in taskbar then click Open Sound Setting.

"Choose your output device" should be your TV.

Let me know if any change.

Setting TV to PCM on a Samsung TV won't help. It only really needs PCM if the TV is sending audio to an external device.

If TV is set to Default Audio device then most, not all, games should use the TV to output audio when you're connected to it. Some games actually detect all audio devices and give you the option to choose between them. Possible those games are defaulting to a device other than what you have set in your OS. In those games enter audio option and check if there is an output/audio device option.

I'd check myself to be sure but I don't own or have any of those games installed/

how are you getting audio out of the tv?

tvs dont decode pcm 5.1-7.1 to their optical outputs, will need to set it to dd or dts
or it may require arc/hdmi to a receiver capable of pulling audio from hdmi

audio path
pc -> reviever -> tv -> arc output -> reciver
pc -> tv -> arc output -> reciever
pc -> reciver

Yup, I did try this and no luck. I also tried disabling the laptop speakers entirely so there was no alternative that the computer could possibly select. In that case though I simply get no game audio from the games that previously only came through the laptop speakers.

For the games that have no audio or audio only through the laptop speakers there are no audio settings beyond volume control in the game. Somehow some of the games are only going to one output or the other and not using the default (which is confusing to me).

I may not be knowledgeable enough to understand what your question is getting at. The audio simply is passed through the HDMI from the laptop to the TV. I have a different laptop that can do this without any issues but this one seems to have some problem I can't quite figure out.

Follow on piece of information from a suggestion that someone else had. I look the laptop and connected it to a stand alone ASUS monitor (that does not have speakers but did have an audio pass through ability with a headphone jack on it) and got the same result as the Samsung TV. I then tested it with an older Hiteker TV and the game that only put audio through the laptop speakers (Lego) played through the TV. The game that didn't have any audio (Terraria) still did not have any audio. I'm not sure what this tells me other than something is different about the one TV than the other devices I have tried to use.
