Good day guys

I just upgraded from a Sony optical Home theater amp to a newer Sony HDMI amp.
Now my HTPC is a second gen I7 with a 550gtx gpu

I have cable from tv to amp and cable from pc to amp

Video comes through perfect but having trouble with audio. In the NVidia app it shows the tv as audio output and nothing else.
in windows audio only shows Realtek optical and Hisence tv.
if I switch to tv it plays audio on the tv.

So I plugged the optical wire and audio works on amp.

Is there setting on gpu that I need to look for.

You need to change the output device in Windows, you need to tell the OS which device to use for audio output

Is your HDMI cable plugged into the ARC port on the TV?

How old is the TV?
 
its a Hisense 65A6K looks like it ha eARC but not sure in what port I have it plugged in. I have a 8K cable from tv to amp.
 
when I select the tv as a output device it plays audio on the tv and not on the amp
I changed to the arc port and played around on the tv settings but still nothing.
 
It absolutely has to be plugged into ARC it cannot work any other way.

Focus on getting your TV sound from the Amp first then worry about the next device.

You’ll need to enable all HDMI-CEC related functions.

But actually thinking about it if your PC is plugged directly into the Amp there should be nothing stopping it from working so there’s an issue on the PC side.

Yes that’s by design you are telling it to play on the TV.

You need to simply switch the source accordingly and it should just work.

Make sure you have all HDMI-CEC functions enabled on both sides.

No it doesn't, he's trying to get sound from the PC through the amp. Not sound from the TV through the amp. ARC is audio return, if he had PC plugged into TV and TV into amp sure, but he doesn't
 
Here's the optimal connection chain for your HDMI cables:

1. PC to an available HDMI INPUT connection on your AMP - Set NVIDIA app audio output settings on the PC to DIGITAL AUDIO via HDMI connection

2. AMP TO TV (Amp connected to eARC / ARC port of TV - Amp AND TV settings for HDMI-CEC set to AUTO or ON)

3. TV audio settings set to EXTERNAL source and NOT Internal speakers only

Yes, see the last line.

You still ultimately want Arc to work regardless of your original motivations so everything you plug in down the line or runs directly on the TV works.

So why avoid fixing it now?

All SONY HDMI amps should natively support HDMI-CEC - I have a decade old SONY BDV-E280 Blu-Ray Home Theatre System connected to a JVC 32" TV set, and it happily processes both the HDMI audio from my Netogy Nova Streaming Box (HDMI 1 input) and Windows 11 PC (HDMI 2 input)

I can also use the power button on the TV remote to turn on the TV set, and it powers up the SONY system as well - and I use the volume button on the TV remote to adjust the SONY system's volume - and when I turn off the TV, and it also turns off the Sony System & the streaming box as well.

Sure but why are we trying to get that sorted if his issue is the pc, more than likely it's a pc configuration issue. Hdmi passing audio has nothing to do with cec. He literally needs to pass audio from his pc to the amp via the gfx card.
Nothing to do with arc or cec, you guys are making it harder for him to fix.

Best solution then is to uninstall all the PC audio drivers via Device Manager, then reboot the PC and let it sort out what drivers it needs to re-install (possibly even uninstall and reinstall the NVIDIA control panel app as well)- go to its Digital Audio Out settings menu & see if the Windows Audio HDMI AUDIO option to route audio from his GPU to the SONY amp is now available...
 
I sometimes connect my desktop pc to my TV via an extra long hdmi cable to my motherboard hdmi, my monitor is connected to the graphic card.

This is mainly when I watch SABC sport (Rugby), the sound is always through my surround sound. My tv and sound system are Samsung.


To OP, the problem might be, because it is a Sony, years ago I had the same problem with my Sony surround sound, it did not want to play surround sound when the tv was connected to another source, i.e. from the dstv decoder, the solution was to connect RCA cables to the TV, only then did it play the sound, weird. Not sure if Sony ever fixed that issue.


Edit: too add, everything was connected via hdmi, but I had to add RCA cables as well.
