Dear Maintainer,

   * What led up to the situation?

        I installed Debian Trixie on a Dell Pro Max 16 (MC16255) with a
        AMD Ryzen AI 9 HX PRO 370. The chipset audio for the speakers and
        headphone jack was unsupported.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

        I installed the 6.16 kernel (which should support the hardware)
        from trixie-backports, the onboard audio was still not detected.
        A quick check showed that the Ubuntu 25.10 and Fedora 43 live ISOs
        did not have the issue.
        I built a custom kernel using the linux-source-6.16 package
        and a modified kernel config based on the config of the
        linux-image-6.16.12 package that enables various modules relate to
        AMD SOC, AMD SOF, and Soundwire otherwise no changes.
        The config diff might not be minimal, since I enabled building all
        modules that might be related and it is attached to my report.

   * What was the outcome of this action?

        After booting with that kernel the speakers and headphone jack were
        detected and worked as expected.

   * What outcome did you expect instead?

        I expected the debian 6.16 kernel to come with the necessary modules
        to support my hardware.
