Hollow Internal Speaker Sound on HP ZBook 15 G6 (Realtek ALC285)

[GitHub issues - opened]

alsa-project/alsa-lib issue #513 was opened from Purgenta889:

I've tested this throughout several different Linux kernels (ranging from version 6.x to 7.x), and no matter which distribution is used, the internal speakers sound considerably emptier and without bass than they should, compared to how they sound on Windows 11.

Hardware Details:

- Laptop Model: HP ZBook 15 G6
- CPU: Intel Xeon E-2286M
- GPU: NVIDIA Quadro T2000
- Audio Codec: Realtek ALC285
- Speaker Brand: Bang & Olufsen (B&O)
- Speaker Type: Dual Stereo

Additional Information:
All audio with bluetooth and wired headphones work perfectly fine, with no noticeable change in bass or quality. According to [this source](https://www.storagereview.com/review/hp-zbook-15-g6-workstation-review), the laptop comes with something called "HP Clear Sound Amp", which could be a contributor to the lack of bass, if it does not work properly on Linux.
