I had the exact same frustrating problem for over a year but FINALLY SOLVED IT! This is what my A135-S4427 was doing: turning the volume wheel would diminish the sound slightly and then rapidly raise it to its peak. Subsequent attempts would have the sound rocketing up and down. I, too, had to use the control panel volume to manage the sound. I pondered putting in another volume control wheel but it seemed a bit of a task. I searched the internet--driver conflict, software conflict, OS reinstall, hardware failure?--to no avail. Just other people with the same problem!

Then one day, I just started turning the wheel back and forth quickly and it seemed like it was kinda-sorta working. I then wondered if maybe there was DUST affecting the connection. I grabbed a can of compressed air and blew it in the front along the edges of the wheel, top and bottom, and the volume control's been working like a champ now for the last month. Hopefully, this will solve your problem, too.

Men may show their gratitude with monetary donations to my retirement fund; ladies, I'll be glad to accept hugs and kisses. <smiles!>

Cheers!~
