A bit late, but it appears that since 6.16 kernel (incl. 6.17) DP audio
is broken on qcm6490-fairphone-fp5 (which is using the Elite audio
architecture, not Audioreach).

Git bisect is pointing to this patch:

  98a8920e7b07641eb1996b3c39b9ce27fc05dbb9 is the first bad commit
  commit 98a8920e7b07641eb1996b3c39b9ce27fc05dbb9
  Author: Dmitry Baryshkov <lumag@...nel.org>
  Date:   Fri May 2 01:41:42 2025 +0300

      drm/msm/dp: reuse generic HDMI codec implementation

It's specifically failing with these errors:

[  177.380809] qcom-q6afe aprsvc:service:4:4: AFE enable for port 0x6020 failed -110
[  177.380851] q6afe-dai 3700000.remoteproc:glink-edge:apr:service@4:dais: fail to start AFE port 68

Do you have an idea?
