I also have the quiet sound after the boot (but not too quiet).

About the noise you mentioned, I didn't hear that yet.

About the "Line Out Playback Volume" and "{Headphone,Speaker} Playback Volume, without my patch, the Headphone and Speaker has its own independent DAC, with my patch, they share one DAC, then the mixer name is changed to "Line Out".

Could you generate 2 alsa-info.txt?

1) under the quiet sound condition, sudo echo 1 > /sys/modules/snd_hda_codec/parameters/dump_coef; alsa-info.sh; then upload the generated alsa-info.txt-quiet-headphone

2) after the sound change back to normal (quiet->not quiet), sudo echo 1 > /sys/modules/snd_hda_codec/parameters/dump_coef; alsa-info.sh; then upload the generated alsa-info.txt-notquiet-headphone.

thanks.
