[alsa-devel] [BUG] Lenovo ThinkBook 16 G7 QOY (Snapdragon X) - No soundcards detected

[thomas.kuang]

Hardware: Lenovo ThinkBook 16 G7 QOY (Qualcomm Snapdragon X / X Plus / X Elite)
Kernel version: 7.0.0-22-generic (Ubuntu 26.04 LTS)
Architecture: aarch64

Problem Description:
-------------------
Audio is not working on this Snapdragon X-based laptop. The system fails to detect any soundcards,
even though the Qualcomm audio driver modules are loaded.

Symptoms:
---------
- `aplay -l` shows: "no soundcards found..."
- `cat /proc/asound/cards` shows: "--- no soundcards ---"
- `/dev/snd/` only contains seq and timer devices, no pcm devices

Relevant System Information:
----------------------------

$ uname -a

Additional Notes:
-----------------
This appears to be similar to issues reported on other Snapdragon X Elite devices
(Dell Latitude 7455, Dell XPS 13 9345). The audio driver modules load correctly,
but the sound card registration fails.

A workaround mentioned in community discussions is to add:
  snd-soc-x1e80100.i_accept_the_danger=1
to the kernel command line, which suggests this may be related to speaker
protection mechanisms not being fully implemented for this platform.

Any help or guidance would be greatly appreciated.

Best regards,

Please post the output of

grep ^ /sys/class/remoteproc/*/state
grep ^ /sys/class/remoteproc/*/name

Try writing start into > /state

This will attempt to power on the DSPs, most importantly the A(udio)DSP
which is necessary for audio to work. If that fails, check dmesg as you
may be missing some firmware files.

As the dmesg suggests, you're missing these firmware files and need
to supply them.
