Public bug reported: Internal speakers are silent on Lenovo ThinkPad X14 Gen 1 2026 / Panther Lake.
Hardware: - Model: Lenovo ThinkPad X14 Gen 1 2026 - Platform: Intel Panther Lake - Audio controller: Intel Panther Lake audio controller [8086:e428] - Codec: Realtek ALC257 - Expected subsystem ID: 17aa:513d - Detected/fallback subsystem ID: 17aa:0000 - BIOS: R39ET25W 1.07 - Kernel: 7.0.0-15-generic x86_64 Problem: The internal speakers produce no sound. The audio device is detected, but the machine appears to fall back from Lenovo-specific SSID 17aa:513d to generic 17aa:0000. This looks like a missing Lenovo-specific ALC257 quirk / pin configuration issue. Expected result: Internal speakers should output sound normally. Actual result: Internal speakers are silent. Notes: This issue has also been reported upstream: https://bugzilla.kernel.org/show_bug.cgi?id=221518 Please let me know if additional dmesg logs, codec dumps, or hda-verb tests are needed.
