Windows 10: realtek sound left side not working

Ok, so my brother just bought brand new logitech Z337 speakers, they're stereo speakers with a sub, and both speakers plug into the sub, which plugs into the computer via aux. we tested the speakers on a phone, and everything is fine. when i plug them into my pc, only the right speaker and sub play sound, the realtek audio manager does nothing, and i cannot get sound out the left speaker, even if i go to sound settings and in the "balance" tab, turn up the left side. his pc is a personally built pc, but none of his parts are off-brand or sketchy. i assumed it was a problem with windows not detecting the left side. can anyone help?

Sound Quality


One thing that sticks out from looking at your "My Computer" specs. You list "ONBOARD 6 CHANNEL (5.1) HIGH DEF AUDIO (AS STANDARD)" which suggests you do not have the correct sound hardware driver. Your motherboard has Realtek sound and the first step is to install the Realtek sound drivers. My ASUS also came with Sonic Studio 2 which is a sound enhancement package. Check the ASUS install disc to see if you have something similar.

May not be a speaker problem.

 

Sound problem

Hi,

We need to investigate further so that we can identify the cause of the issue. We suggest running the Troubleshooter and see if it helps. Follow the steps below:

• Type and select Troubleshooting on the Search bar/Cortana.
• Click Hardware and Sound.
• Select Playing Audio under Sound.
• Follow the steps that will be provided.

If the steps does not work. We suggest downloading a fresh copy of the audio driver from Realtek and see if it helps.

Looking forward to your response.

 

Onboard Sound Not Working

A friend and I built a PC yesterday for him, using the MSI P67A-G43 motherboard. Everything seems to be working fine but we're having an issue getting his sound to work. A RealTek driver was automatically installed when we installed Windows 7 64 bit, but since we couldn't get it to work we uninstalled it and got the one off of MSI's site. When we go to "Playback Devices", there are 4 things listed there. The AMD sound from his card, which is disabled, "Speakers" from RealTek which aren't detected. Optical from RealTek, and RCA from RealTek. I suspect we need to be using the "Speakers" device, but why is it saying nothing is detected even when he has headphones or speakers plugged into the back?

He has tried the back plugs along with the front audio, which we made sure to plug in to the motherboard. Any suggestions on how we can fix it?
