looking for a free sound mixing program

[Donut]

to keep this short, i plug a male to male 3.5mm headphone cord into my tv, and then into a pair of headphones so i can use headphones for my games. what i want to do it take the male end coming from the tv, plug it into the microphone port on my laptop, and then have a sound mixer allow me to output the sound coming from the mic (tv) and the sound coming from the computer. i want to be able to listen to music and use my tv headphones at the same time. does anybody know of a free program that lets you do that? i did some searching on google but tbh i dont really know what to look for.

if im an idiot and windows has a built in function for this, feel free to call me an... idiot :v:

Right Click on the Volume Controls > Recording devices > Right Click on Microphone > Properties > Listen > Listen to this device

No 3rd party programs needed.

i had a feeling it would be simple. thanks :)
E: i dont have the option to listen under the microphone device
E2: nvm, it was working by default. i am an idiot, lol.
E: i was just getting feedback. it doesnt work. i played around with the sound options, then googled "microphone playback", and it seems some sound cards dont support playing mic sound through the speakers. i have a built in mic, so i suppose it makes sense that it wouldnt work on my pc (or would be turned off by default), so what i need is what i said before: a program that will allow me to play my mic input through my speakers

Hey I found it! After about half an hour of desperate button pushing and knob tweaking, I managed to hear my microphone through my speakers. Here's how to do it: Right-click on the sound icon in the system tray and select Playback Devices (or alternatively, go to Control Panel and select Sounds). Once in the Sounds window, double-click the Speakers options, then go to the Levels tab, and there you'll find the available options. Why oh why did they make it so complicated?


It was in the comments section of your link, if you already tried this disregard.

Isn't that same thing as using "Listen to this device" under the Microphone properties?

[iizahsum]

I just noticed it in the comments of the link he posted, I don't know anything about recording audio so if it's the same thing just disregard it.

yeah i tried that. i just dont have anything other than a slider in there. im thinking this might just be an issue of not having the functionality available, but that just doesnt make sense not to include this function. could it possibly be a hardware limitation? i have an hp dv9000 entertainment laptop, so i figure it should have something as simple as this

[Syuusuke]

Wait, no you can't use your mic-in for that, that's a comptley different functionality.

If anything you should use the Line-in jack on your sound card.

oh. i dont have a line in though. im on a laptop, so i have 3 ports in the front of it. 2 headphone jacks and one mic-in, which i assumed was a line in since when something is plugged in there it overrides the built in mic

[Syuusuke]

Why is there 2 headphone jacks?

[Donut]

i assume its because this is an entertainment PC with a big screen, so people can plug two sets of headphones in without using one of those splitters. iv seen the two headphone jack thing before in small portable tvs, so thats what i figured they were for.
