Hardware: - Laptop: Lenovo Yoga 7 2-in-1 16AKP10 - Audio: Intel HDA (Realtek ALC287 codec, quad speaker setup: 2 top + 2 bottom)
Software: - Distribution: [CachyOS] - Kernel: [6.17.0-rc5-2-cachyos-rc and 6.16.6-3 (same result in both kernel versions)] - ALSA version: [Advanced Linux Sound Architecture Driver Version k6.17.0-rc5-2-cachyos-rc. (got with command cat /proc/asound/version)] - Desktop environment: [KDE Wayland]
Problem: When adjusting system volume, only the top speakers change their volume The bottom speakers keep playing at full volume regardless of system settings. (expect when volume goes to 0 or mutes then all speakers mute)
Steps tried: - Tested with PipeWire - Checked `alsamixer`: only one speaker group responds to volume changes. - In Windows 11, all four speakers respond correctly → confirms hardware works. - Updated BIOS, firmware, and kernel → issue persists.
Expected result: - All four speakers (top + bottom) should respond to system volume control.
Actual result: - Only the top speakers change volume. Bottom speakers remain loud at all times.
