Adil, 

what I can tell is that since kernel-2.6.10 there are two new options
wich are not known in kernel-2.6.9 and lower. Since those options are
not known in former kernels it might only look like those options are
off while in fact they are "not set". I upgraded to kernel-2.6.11 over
the weekend on an other system and when I first started I had no sound
as well (what a surprise). The two options appeared to be off. I
switched them on and off. After that the sound started to play right
away. I didn´t change anything else just the two options.
