Last Sept on this mobo http://www.abit-usa.com/products/mb/techspec.php?categories=1&model=147 I installed Mandriva 2006. Sound worked OK, but there was a low output level to my home stereo amp. I had to turn the volume up substantially more than normal for other inputs, and there was audible hum. Last month I added 10.0 from the DVD on the same system. With SuSE, the hum is much worse, probably 2-3 times as bad, and to get there I have to turn up the volume considerably more. Is there some low level adjustment in the OS or driver somewhere that can make the hum go away and the output level go up? -- "Blessed is the nation whose God is the Lord."
