Solved! PC connected to 4k TV audio out to Home theatre 5.1

[PCnewbie123456789]

I have a gaming PC connected to a 4k Hisense TV (through HDMI 2.0) .that is used as a monitor ONLY .

The PC have no sound card , just the built on Mobo (H87M-PLUS)
which doesnot seam to have the connections to support 5.1 audio.

however my VGA is AMD rx480 . i think i can do audio 5.1 via HDMI right ?

I donot have a Home theatre yet , but i am planning on buying one. but i want to know what connections to look for . i will never use the DVD or Blueray of the hometheatre or connect a receiver to the TV.

MY initial guess is to use the digital audio out from the TV to the home theatre or speakers , is this the right way? does this connection support 5.1 audio that the TV should get from the PC through HDMI ? does all home theatres accept such input .

Sorry if my question is very trivial , but i am noob in audio systems

I think you can configure the audio jacks on the mobo to output 5.1 in the HD audio manager window.
That won't help you if you buy an HTS package because these don't have usually have 5.1 discrete analog audio inputs. Most HTS do the surround processing via optical or HDMI input. If you get a 5.1 channel speaker system then you can use those connections since when you use a 5.1 speaker the PC does the processing.
You can get an HTS with HDMI inputs. That will have a "receiver" as the main unit that the HDMI input connects to and an HDMI output that connects to the TV.

thank u , Th HTS does have HDMI input but i donot know if it will work i use 2 HDMI cables from the VGA , one for the TV and one for HTS , the computer might "think" that it is a second display ... but you didnot comment on the optical output solution that i am considering . I know it should work if i get a sound card with optical audio out port . but i am trying to save money.
