Hello,
I have a HP Pavilion dv7 laptop (LS066EA#UUZ), with:
# cat /proc/asound/card0/codec* | grep Codec Codec: IDT 92HD81B1X5 Codec: Intel CougarPoint HDMI
when play sound without any tweaks, I get a very weak sound output. If I want to have "beats audio", that is subwoofer and all speakers, I need to set:
# cat /etc/modprobe.d/alsa-base.conf options snd-hda-intel model=hp-dv7-4000
Could the snd_hda_intel alsa driver be updated to recognize and setup the driver accordingly?
alsa-info.sh output here:

Could you check whether the patch below works?
