Hey Urko, do you know what might be causing the problem for my post above? I tried turning off SRS and just leave Dobly Audio enhancements on and the sound was still horrible. I did get an error when trying to use installer to install your modified driver. I worked around it by using device manager manual install. Can you add my device information to the INF? I would love to give this another try. Also just to clarify the installation process: 1. Disable secure boot/driver signature check 2. Install modified driver using installer 3. Install the DTS software packs 4. Install the SRS software packs Right? Do I need to install both Dolby and SRS or just one of them is enough?
