When the record starts, the driver turns on MICBIAS and the voltage is pulled up for an instant. If the receiver starts to capture the signal between the instant, there is an pop noise in the stream beginning. To avoid the pop noise, the driver makes a delay in the sequence. After MICBIAS powered up, the driver waits 300 ms for the voltage going down. Then turns on the ADC output, and sends signal to receiver. The pop noise can be erased.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
