Remove chips not needed for I2S connectivity



Hi,

Great job! You are going as crazy as me!

Regarding remove of chips the 74HC125 need not be removed. Alternatively, just lift pin 14 Vcc (the pin above the "D" of DGND1). Check its connection to the reg.

74HC125 is driving the Dig trans and optical output. Without power supply, the trans will no longer work, hence no need to remove. The optical output will not be working too, but it will still draw a small amount of current.
