Real tec audio manager installs. But won't launch, not in tray or control panel?

Basically I used a temporary HDMI monitor for a while and then switched back to the original VGA monitor I used before and all of sudden my audio does not work.

If anyone has had anything similar happen please answer.

But here's additional Information:

I have reinstalled both nividia and realtec drivers countless times and still no luck. I have launched BIOS and onboard audio was already set to [auto]. (There was no enable option).

I have looked a dxdiag and it tells me there's no sound card installed, this is a lie because i check my motherboard and saw a small chip with 'Realtec' on it. And realtec worked before.

The speakers work fine as my iPhone could play music perfectly from the AUX port.

I noticed 'Nividia HD audio' in device manager but I disabled all 5 drivers and then installed realtex with no luck what so ever.

Is there any solution (especially free) or has anyone every had something similar which they solved?

Use a mini speakers in mother board audio jack for chk your audio, update your audio driver from device manager ' or download {ad} software and run it…0r chk your audio setting
