Hp spectre 14 ea000 audio fix: Ubuntu 21.04

There has been a lot of questions on the few solutions to hp spectre 14 ea000 audio issues and the best temporary fix i got for my laptop (hp spectre 14: 11th Gen Intel® Core™ i7-1165G7) has been the amp pin fix below;

#!/bin/bash

sudo hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x01
sudo hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x01
sudo hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x01
sudo hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x00

My audio sound card is alc245. This was made into a script and ran everytime i needed audio from any application. The side issue here is, the audio source must be active: e.g a movie or audio must be playing in the background before the script will activate the sound audio. And immediately the sound stops playing, the audio sound source it disable again. This cycle has to be repeated again to have audio and is quite frustrating.

The solution i temporarily adopted to prevent the audio going to idle is to comment out a section below from the /etc/pulse/default.pa

### Automatically suspend sinks/sources that become idle for too long

#load-module module-suspend-on-idle

After this, my audio does not go into idling again. I only have to run the script once at login. My laptop has the facial login, with howdy, i don't have to type in my password when i run the script. I added the script to my auto-start with ubuntu startup application and my audio works automatically at login with howdy.

Need i also mention that i run kernel-5.13.12-051312-generic. My audio still works after suspend and hibernation. I have been able to reproduce this with ubuntu 21.04 + gnome40 desktop only. Had issue on gnome 3.38. This also works perfectly with ubuntu 21.10 impish development.

I hope someone can make something better out of my discovery and permanently make the audio working seamlessly after installation without tweaking.

Good news! Just installed Ubuntu 21.10 beta but the sound issue persisted out of the box. I installed kernel-5.15rc2 and sound started working. Bet a solution at last! Thanks Ubuntu team. Great work. My spectre 14 ea000 is known to have keyboard delay after each boot. This requires me to consistently tap the keyboard keys randomly until an input is registered at login. It works fine until next reboot. I resolve this by editing the line below to /etc/default/grub file; Locate the line,

GRUB_CMDLINE_LINUX_DEFAULT=" “

to add i8042.dumbkbd=1

This resolves the keyboard delay issue. Only side effect is that the caps lock key led indicator light does not light up. I now use gnome extension to indicate caps lock state.
