P.S. 開機後，如果發現PulseAudio無法連接，執行sudo rmmod snd_hdmi_lpe_audio

雖然該作者是針對Fedora系統客制，不過Arch Linux相關網頁卻也建議使用者依照該網頁編譯Kernel，剛好司徒習慣使用的Linux系統是Debian系統，於是司徒在Debian系統上編譯測試該客制Kernel，結果竟然可以完美地支援電池和音效等相關驅動，於是司徒借花獻佛、依樣畫葫蘆，整理成如下：
$ cd $ git clone https://github.com/jwrdegoede/linux-sunxi $ cd linux-sunxi $ make-kpkg clean $ fakeroot make-kpkg --initrd --revision=0.0.1 kernel_image kernel_headers $ sudo dpkg -i ../linux-image-4.13.0-rc2+_0.0.1_amd64.deb $ sudo reboot
