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:

I'm not quite sure that I have the exact same hardware, but I think so. I have 5 speakers (rear left and right, front left and right + subwoofer) Here is my alsa-info: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1056669/+attachme... In my case, model=hp-dv7-4000 doesn't fully solve the problem. The subwoofer works but it is not mapped as such. After some tests, it seems that the alsa's speakers rear left and rear right are mapped to the subwoofer. The front ones are alright. With the model=hp-dv5 that I'm using, the subwoofer isnt recognized at all, but the rear speakers are correctly mapped.
Also, with hp-dv7-4000, the internal microphone is still used when a micro jack is plugged in. That's not the case with hp-dv5.
If you think there's a configuration issue on my side, please let me know, but I think hp-dv5 is actually a better default choice if I have to choose between both.
Kind regards,
