ALSA: hda - Add workarounds for pop-noise on Chromebook with ALC283
The headphone automute on this machine triggers annoying pop noises. It seems that only the first DAC can be used, the secondary DAC always results in this problem. This patch disables the secondary DAC with a few additional workarounds. Signed-off-by: Kailang Yang <kailang@realtek.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
