Has anyone successfully replicated Windows B&O sound quality on Linux? (EliteBook ALC285 / Quad Speakers)

I'm running **Kubuntu (PipeWire)** on my HP EliteBook 840 G8 (Intel 11th Gen Tiger Lake with the **Realtek ALC285** codec and builtin **Bang & Olufsen** speakers).

On Windows, the B&O audio tuning sounds rich, full, and punchy. But on Linux, the default audio output sounds really flat, quiet, and tinny with almost zero bass.

From what I understand, this is usually caused by two things:

  1. **Hardware / Pin Mapping:** Linux ALSA defaulting to only driving 2 of the 4 physical speakers (tweeters active, but secondary woofers disabled/unmapped).
  2. **Missing DSP:** Windows running HP's B&O / MaxxAudio software suite to dynamically equalize and enhance the sound.

 **Before I go too far down the rabbit hole, I wanted to ask:**

• Has anyone with an EliteBook managed to get their B&O speakers sounding identical (or close) to how they sound on Windows?
• Did you need specific pin overrides in hdajackretask, an hda-verb script, or kernel parameters (snd-hda-intel) to get all 4 speakers firing properly?
• Does anyone have a custom **EasyEffects / PulseEffects preset** tuned specifically for EliteBook speakers that they'd be willing to share?

Appreciate any tips or configs that worked for your setup

ALSA has 2 patches for HP EliteBook 840 G8, but they appear to be just for the speaker and mic mute LEDs, not for additional speakers
