HP Omen 15 - ek0010ca - audio issues

Intel Corporation Comet Lake PCH cAVS - Realtek ALC245 - uses SOF. This is going to be just a briefly cleaned up version of my notes.

I'm hoping someone has had this issue and can help, I have been plodding away trying to figure it out to no avail. All of my searches has not brought up anything that really matches my issue.

When using the GNOME control center sound test, audio is delayed/broken on both sides, I'll hear a "t left" or "front" for example. Looking at the output bar, I can see the full audio being played. The audio is just not being output right, at the speakers.

speaker-test -> audio sounds normal, reports playing out Front Left
channel, but audio is coming out of both speakers

speaker-test -c2 -> Front Left channel has skipping audio at regular
intervals (1s on, 1s off), Front Right channel has skipping audio at
regular intervals (1s on, 1s off)

speaker-test -c2 -s1 -> Front Left channel has skipping audio at
regular intervals (1s on, 1s off) out of the left speaker

Playing a video or game, audio sounds correct, move balance to left and the audio skips, move the audio to the right and it skips. As long as the balance is centered, the audio plays correct. However, there is a delay to the audio start, this is noticeable in Minecraft. If 0 sounds are playing (according to the debug), and I make a sound occur, it is silent. If I don't delay and keep making the sound (e.g. mining) the sound starts. If I wait 10 seconds, the behaviour repeats.

Tried Pulseaudio and Pipewire, both exhibit the behaviour

Tried multiple Linux distros (ArchCraft, Axyl, Pop!_OS, Ubuntu, Manjaro), issue follows

For Pop!_OS 21.10 and Ubuntu 21.10, kernels are 5.15 and 5.13 respectively, both exhibit the behaviour. Axyl had the bleeding edge kernel in the 5.16 series, issue still present

Complete shutdown of Pulseaudio (and confirmed it was not running), and used speaker-test directly with ALSA, issue was still present

Since the I took Pulseaudio out of the formula, commenting out module-suspend-on-idle does not help

Disabling power saving does not help

Laptop has Bang & Olufsen speaker setup (not sure if that really matters)

Audio works as intended in Windows 10

I have the same laptop model and am experiencing the same problem with clipped audio when playing audio books/podcasts or listening to anything speech related. Sure is annoying as hell. Tried all suggested solutions from the web with no result so far.

However I've found a simple solution to this problem. Simply play a background sound, such as calm ambient songs at low volume.

It seems the speech pauses between words caused the audio subsystem to prematurely stop and then to start again at the beginning of the next word, at a slight delay, causing the word to be clipped. By playing the background song, even at low volume will keep the audio subsystem to remain continuously active/open. Good luck.
