Thanks,

I was able to test this and tried few things. The SND_SST_IPC_ACPI has
depends but someone can still selecta ACPI machine and cause these errors so
I have moved the onus on machines and thus removed the depends and moved to
all the ACPI machines. The PCI ones don't care about this so they are okay.

Thanks for reporting, patches are posted now.
