I have the same problem with a ThinkBook 13x Gen 2 with Ubuntu 23.04. The sound works properly when connecting external speakers or headset, but I couldn't get the internal speakers to work :( This laptop also has an ALC287/3306 chip with a CS35L41/CSC3551 amplifier. This seems very similar what is mentioned here:

https://gist.github.com/lamperez/862763881c0e1c812392b5574727f6ff?permalink_comment_id=4526397

journalctl displays the following message: "Error: ACPI _DSD Properties are missing for HID CSC3551".

I tried it with the base kernel (6.2.0) as well as the latest one (6.3.3). The issue occurs regarless of the BIOS version (factory version: HXCN49WW and 20230517 version: HXCN52WW).

I used the ACPICA tools to extract the ACPI tables and noticed the entries relative to the CSC3551 did not contain the required "cirrus" and "dev-index" parameters.

This is quite disapointing and I will juste return the laptop to Lenovo.
