Stop Tensor device's AOC daemon for reducing significant jitter

     <li>disables the effects framework of the mixer (to interface to equalizers, virtualizers, visualizers, echo cancelers, automatic gain controls, etc.) for obtaining a nearly direct low jitter audio pass,</li>
     <li>disables the android built-in spatial audio feature (A13 or higher; especially Tensor devices) for obtaining a nearly direct low jitter audio pass too,</li>
     <li>disables pre-installed Moto Dolby features and Digital Wellbeing (please uninstall this manually if remaining as a usual app) for the same as above,</li>
+    <li>stops Tensor device's AOC daemon for reducing significant jitter,</li>
     <li>adjusts a USB transfer period of the USB HAL driver (not the recently common hardware offloading USB (tunneling) driver, but including Tensor device's offloading USB driver) for directly reducing the jitter of a PLL in a DAC (even in an asynchronous mode); Use <a href="https://github.com/yzyhk904/USB_SampleRate_Changer">"USB_SampleRate_Changer"</a> to switch from the usual hardware offloading USB (tunneling) driver to the USB HAL one,</li>
     <li>sets a higher bitrate limit of bluetooth codec SBC (dual channel mode) for EDR 2Mbps entry class earphones (not for EDR 3Mbps performance ones, but including AV amplifiers and BT speakers),</li>
     <li>sets an audio scheduling tunable "vendor.audio.adm.buffering.ms" "2" to reduce jitter on all audio outputs,</li>
