v0.1.1

• The add-on's default sound card (slave) is now hdmi_bmc, the optical S/PDIF device
  provided by the add-on service.rpi-gpio-spdif (an ALSA plugin, no kernel driver), instead
  of the card iec958:CARD=SPDIFout,DEV=0 of the old rpi-gpio-spdif kernel driver. With
  HDMI or another sound card the setting must be changed, as before.

v0.1.0

First public version.

• ALSA PCM plugin leadtap: passes audio unchanged to any slave PCM, reports the slave's
  delay, and writes a copy (48 kHz, S16_LE, stereo) to up to four named pipes a fixed time
  before the audio becomes audible.
• IEC 61937 bitstreams give a silent copy; each pipe is independent and never blocks the
  player.
• LibreELEC / Kodi service add-on service.alsa-leadtap (aarch64): the plugin with the
  wled-audiosync binary, settings for sound card, lead and WLED target, ALSA configuration
  as a drop-in file in /var/lib/alsa/conf.d.
• Selftest with a simulated slave, no audio hardware needed.
