This setup was done on an HP EliteBook 840 with Intel Tiger Lake hardware, running Ubuntu 24.04 LTS.

Ubuntu 24.04 ships with PipeWire and WirePlumber by default, which is a solid foundation—but getting microphone, noise suppression, and sane device naming to work properly on this platform still requires some manual tuning.

This post documents the exact steps I use to achieve a reliable, high‑quality audio setup suitable for calls, recordings, and daily work.

TL;DR

• Hardware: HP EliteBook 840 (Intel Tiger Lake)
• OS: Ubuntu 24.04 LTS
• Switch the sound card to pro-audio mode
• Max out levels with alsamixer and persist them
• Use WirePlumber Lua rules to rename devices and disable unused ones
• Install PipeWire RNNoise for noise suppression
• Use Quick Settings Audio Panel for fast source/sink switching

Result: clean mic input, stable routing, and no cluttered device list.
