This PR adds an `If.bass` condition to `ucm2/HDA/HiFi-spk.conf` so that when `Bass Speaker Playback Switch` is present, ALSA UCM defines `PlaybackChannels 4` and channel positions (`FL`, `FR`, `RL`, `RR`). ### Benefits - Automatically routes audio across all 4 speakers (tweeters + woofers) in modern sound servers (PipeWire / PulseAudio). - Eliminates the need for hardcoded machine-by-machine overrides for 4-speaker HDA setups. - Tested on Lenovo Legion Pro 7i Gen 10 (DMI Product `83F5`).
