## Audio (neon)
Speakers, headset jack and mic work under neon thanks to custom fixes
applied 2026-03-05, documented in **`AUDIO.md`**: WeirdTreeThing's
`chromebook-linux-audio` script (`avs` driver via
`/etc/modprobe.d/snd-avs.conf`, cros UCM profiles, WirePlumber
headroom), avs topology blobs hand-downloaded from upstream
linux-firmware into `/lib/firmware/intel/avs/`, and a `Syntax 7` →
`Syntax 6` sed over the UCM files for neon's alsa-lib 1.2.11. FydeOS on
the eMMC has no audio yet (not investigated).
