Reorganize the repo so it can rebuild the audio hub on any Pi, not just the live `adac` box: - README.md: now a project landing page (overview, repo map, deploy summary) instead of the adac-specific maintenance guide. - MAINTENANCE.md: the "how it's wired / day-to-day upkeep" guide, genericized with <pi-host>/<pi-ip>/<lan-cidr>/<desktop-host> placeholders. - config/: the actual PipeWire/WirePlumber drop-ins as deploy-ready templates (<VOLT_SOURCE>/<VOLT_SINK>/<LAN_CIDR> placeholders, with the commands to resolve them in each file's header comment). - systemd/bt-agent.service, firmware/config.txt.snippet: the remaining deployable artifacts. - instances/adac.md: the live deployment's real values (host, IP, Volt serial, paired phones, history) — the one place machine-specific data lives. - RUNBOOK.md: replace the hardcoded LAN subnet with <lan-cidr>. - root-README.md: genericized; .gitignore keeps local harness settings out.

# These are EDITS to the existing file, not a drop-in — apply them by hand, then reboot.

# 1. Disable onboard + HDMI audio so the USB interface is the only sound card.
|
|
# Change the existing `dtparam=audio=on` to:
|
|
dtparam=audio=off
|
|
# And append `,noaudio` to the existing vc4 overlay line:
|
|
dtoverlay=vc4-kms-v3d,noaudio

# 2. Wired-only box: disable onboard Wi-Fi. Add ONLY after the wired Ethernet
|
|
# cutover is confirmed working (RUNBOOK §8.5) — never disable Bluetooth here.
