Added

  • A new Audio Card menu in recovery mode. Pick your card (IQaudIO CODEC, HiFiBerry or AudioInjector) and the unit rewrites config.txt, resets the mixer to a known-good state for that card, and reboots. Pick the card you already have to get your mixer settings back to a known-good state.
  • The recovery main menu now shows which audio card is active.
  • MOD-UI has a new on-device SFZ builder: make your own sfizz samplers from your own samples, right on the pi-Stomp!
  • Support for the Compute Module 5 and the Pi 500.

Changed

  • The first boot now sets up the mixer for the audio card enabled in config.txt, before JACK starts. The known-good mixer states live in the pistomp-audio package, so they can be updated over-the-air.
  • Factory Reset now also resets the mixer for your card. If it can't tell which card you have, it leaves your mixer settings alone.
  • File selectors now appear at the top of a plugin's settings in MOD-UI, as they tend to be the most important field when present.
  • pi-Stomp now prefers WPA2 when an access point offers both WPA2 and WPA3 (SAE). (#258 on pi-stomp)

Fixed

  • A CM5 or Pi 500 was set up as a v2 (Core), with the boot splash upside-down. Only a Pi 5 was detected as v3 (Tre).
  • Leftover Wi-Fi driver settings from images before 2026-08-26 are cleaned up, so only one file sets the brcmfmac options.

Known issues

  • On a pi-Stomp Core (v2), the LCD sometimes stays white after you reboot from the recovery menu or shut down from the pi-Stomp menu. Un-plug and re-plug the power and the problem will resolve.
