alsa-project/alsa-ucm-conf pull request #747 was opened from pma1:

Some machines have both cs42l43 and cs35l56 speaker amps on SoundWire. Only the first spk: tag in CardComponents was handled, leaving the second codec without init, control remap, or mute LED.

Detect cs35l56 directly in CardComponents instead of SpeakerCodec1, and when cs42l43-spk is also present, initialise both codecs and extend the mute LED remap to cover all amp channels.

Toggle Speaker Switch in both device confs and set up cross-codec routing and mute tracking as needed.
