Hello,
I recently bought a new laptop for school and study. I bought it second hand, since I couldn't afford a fully new one.
When looking for the laptop, I make sure everything was correct. I opened up a YouTube video and the video started playing normally. No graphical problems were to be seen, nor any audio problems. Plugged in my earphones and everything still went smoothly. I litteraly checked everything and every little aspect, and I finally bought it. It was running Windows 7 Home Edition 64 bit.
Once home I did a factory reset and I cleared the entire HDD, purely because I wanted to be sure that I could start with a clean Windows 7.
Once it finished and booted up, I updated Windows 7 untill I couldn't no more. Around now the time was about 02:00 at night.
I wanted to watch my series on the Internet, yet I had no sound. I unplugged my earphones and replugged them and again. No sound.
I checked Windows sound at the bottom right corner and while the video was playing it showed no activity of any sound (no bars going up). I then unplugged the earphones and tried it on normal speakers. Nothing again.
Strange thing is though, when I plug in my earphones and I go to Windows sound options and from there I chose "Communication headphones (IDT High Definition Audio CODEC) I pause the video, lower or higher the sound and play the video the sound works perfectly fine. But as expected, when unplugging the earphones no sound again. I did the exact same process without earphones being plugged in, but no succes.
When playing YouTube video's this process works. But trying a downloaded video, or the sample sounds from Windows itself, it gives me an error.
If I play a game I have no sound.
I don't know where I can see the exact modelnumber of the laptop, but it's a HP Pavilion DV6 with an i5 2410M, 4GB of RAM 450GB of storage (14,5GB recovery) and a AMD HD6770M and Beats Audio.
Any help is much appreciated!
