According to the ACPI that I have access to, this is not correct - the 
Speaker ID is on index 2 not index 1.
Index 1 has a reference to the interrupt line. Therefore this should be:

	{ "17AA386E", 2, EXTERNAL, { CS35L41_LEFT, CS35L41_RIGHT, 0, 0 }, 0, 2, -1, 0, 0, 0 },

According to the schematics I have access to, both amps have a reset 
line. The reason for any issue you see may be
because you have assigned the speaker id for the interrupt gpio in ACPI 
as mentioned above.

Thanks,
