Dear Debian maintainers,
I am experiencing a complete lack of sound output from the internal speakers on my Lenovo Legion Y9000X 2021 laptop after a fresh installation of Debian 13 (Trixie). The headphone jack works perfectly, but the speakers remain silent.
**Hardware details:**
- Model: Lenovo Legion Y9000X 2021
- Audio codec: Realtek ALC287
- Amplifier chip: Cirrus Logic CS35L41 (two amplifiers, one per channel)
**Software environment:**
- Debian version: 13 (Trixie)
- Kernel: Linux debian-world 6.12.95+deb13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.12.95-1 (2026-07-04) x86_64 GNU/Linux
- ALSA utils: 1.2.14-1
- PipeWire: 1.4.2-1
**Steps to reproduce:**
1. Boot the system with default settings.
2. Log in to the desktop environment (GNOME/KDE/etc.).
3. Open the system sound settings or `pavucontrol` and set output to the built-in speakers.
4. Play any audio file or test sound.
**Expected result:**
Sound should be heard from the internal speakers.
**Actual result:**
No sound from speakers, but sound plays normally through the headphone jack when inserted.
**Additional observations:**
- The speakers are correctly listed in `cat /proc/asound/cards` (card 0 is the HDA Intel PCH with ALC287).
- The CS35L41 amplifiers are detected in `dmesg` but seem to remain in a powered-off state.
- Running `alsamixer` shows no muted channels, and all volume sliders are at 100%.
- The problem persists after rebooting, and even after loading `snd-hda-intel` with `model=auto` or `model=legion` (tested via kernel module parameters).
**Diagnostic information:**

**Suggested approach:**
I suspect the issue lies in the kernel’s support for the CS35L41 amplifier, possibly due to missing or incorrect initialization sequences for this specific combination of ALC287 and the Cirrus amp. Similar bugs have been reported for other Lenovo models (e.g., ThinkPad X1 Carbon) with the same audio hardware, and they were fixed by adding proper quirk entries in the `snd-hda-intel` driver.
Thank you for your time and effort in maintaining Debian.
Sincerely,
Kaspar
