Vinod,

I have attached the dmesg that occurs after I play the sound test. 
(dynamic debug and FE-BE was set via SSH terminal)

Antonio,

While it is true that I had not played any sound when I had collected 
the interrupts from previous mail, after doing the test for Vinod above 
I again collected the interrupt count, unfortunately as you can see it 
is the same...

root@mykro:~# cat /proc/interrupts | grep intel
    7:          0          0          0          0   IO-APIC 
28-fasteoi   intel_sst_driver

Additionally, you were correct about the sorting of interrupts, as my 
dissembled DSDT table shows:
(from Device(LPEA) section)
       Interrupt (ResourceConsumer, Level, ActiveLow, Exclusive, ,, )
                 {
                     0x0000001D,
                 }
                 Interrupt (ResourceConsumer, Level, ActiveLow, 
Exclusive, ,, )
                 {
                     0x00000018,
                 }
                 Interrupt (ResourceConsumer, Level, ActiveLow, 
Exclusive, ,, )
                 {
                     0x00000019,
                 }
                 Interrupt (ResourceConsumer, Level, ActiveLow, 
Exclusive, ,, )
                 {
                     0x0000001A,
                 }
                 Interrupt (ResourceConsumer, Level, ActiveLow, 
Exclusive, ,, )
                 {
                     0x0000001B,
                 }
                 Interrupt (ResourceConsumer, Level, ActiveLow, 
Exclusive, ,, )
                 {
                     0x0000001C,
                 }

For now I can research into overriding the DSDT so the interrupts are in 
order.

Thanks-

Tyler
