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.
