My motherboard is ASUS P5QL PRO..That motherboard producing very low volume sound..The driver is Realtek...I have installed Windows 7 Ultimate..I set the volume to maximum level in all volume setting. My speaker is sonic gear spectra 200..The problem is volume is not very loud compared to my previous motherboard Gigabyte P31-DS3L...So what I should do? Is there any software to increase the volume?
