BUGREP No hardware speaker volume control on ALC287 (Lenovo Yoga, Ubuntu 25.10): master/sink volume has no effect

["Sergii O. Uriupin" <urupin@gmail.com>]

Hardware:
- Laptop: Lenovo Yoga (AMD APU with ALC287)
- Audio: Family 17h/19h/1ah HD Audio Controller, codec Realtek ALC287
- OS: Ubuntu 25.10 (kernel 6.17.0-6-generic)
- Audio stack: PulseAudio 17.0 (PipeWire audio removed)

Problem:
- System master/sink volume (1–100%) does not change actual speaker 
loudness.
- Only slight change >100% (as if a high-frequency path kicks in).
- Actual audible volume changes only when per-stream volume is adjusted 
(e.g., `pactl set-sink-input-volume <id> ...`).
- In ALSA controls there is no usable “Speaker Playback Volume”, only 
switches; so PA/desktop slider has no effect on internal speakers.
- Reproducible after clean boot, with PulseAudio as the active server 
(pipewire-audio removed).

Data:
- ALSA info: <ALSA_INFO_URL>
- `amixer -c1 controls`: <paste output>
- `amixer -c1 contents`: <paste output>
- `pactl info`: <paste output>
- `pactl list sinks short`: <paste output>
- `pactl list sink-inputs short`: <paste output>

Expected:
- Master/sink volume should control speaker loudness.

Actual:
- Master/sink volume does nothing; only per-stream volume changes affect 
sound.

Notes:
- UCM profile (HDA/HiFi) points speaker to non-existent “Speaker 
Playback Volume”; mapping to Bass Speaker volume locally (user UCM 
override) still yields minimal effect. Needs correct UCM/driver mapping 
for ALC287 on this platform.
