Greetings! I have an issue with my Toshiba laptop at the moment. So about 2 weeks ago, my stock Toshiba hard drive failed on me. Toshiba told me the process of making a Windows installation disk and then using the key on the bottom of my laptop to get Windows 7 Home Premium. So i did just that. I was enthralled after realizing I wouldn't have anymore Toshiba crapware on my laptop, but that means I have to install all of the drivers manually. No big deal for me really. So I installed all of the drivers and I thought everything worked until I plugged my headphones in. No sound comes out of them! I installed the Realtek audio driver and it recognizes that a device is plugged in. The window pops up after plugging in my headphones. However, I played the test sounds and nothing comes out. Even the little diagram on the right side of the screen recognizes a device is plugged in, but no sound. I also have OpenSUSE 12.3 installed (dual-boot) and the headphones work on there. In Device Manager, it says that there is something missing, but under "Other devices" is lists and "Unknown device". It is present even when the headphones are not in the laptop. I don't know what else to try. Thanks for anyone who helps!
