Graphics card as audio section?

I'm just wondering, if the board's audio section is brokwn or outright missing, can the graphics card still put out audio signal? Just a thought about saving space on ITX boards, after all an audio section takes up more board space than a post code display and will let the VRM get bigger.

What board?

So I'm assuming you would want audio coming from the TV/monitor?

 

I believe most modern GPUs have their own on-board sound, so I don't see why not. But I can see audio input becoming another challenge. You can go ahead and try it (if you have a board with broken sound or something) and see if it works that way.

Any board. I know they'll work without audio but I wonder if you need the onboard components to hear anything.

No need for audio hardware at all for HDMI/Bluetooth sound output.It's basically only there for the analog ports (and optical/coax out if there is one). You can easily try that for yourself by disabling the sound card in device manager (or in the bios).

No the boards audio section is not needed for the graphics card audio to work

Please quote or tag  @Ben17 if you want to see a reply.

If I don't reply it's probly because I am in a different time zone or haven't seen your message yet but I will reply when I see it ?

Graphics cards can't really process audio themselves they output a display signal that also has audio but whatever you are out putting to your monitor or TV is the device actually converting it to analog not the graphics card. If you want to save space you can take audio externally with a dac/amp. And just plug them in through toslink or usb.
