   @wangxiaohu2026 Instead of creating new topologies for sn624x, can you change .sof_tplg_filename = "sof-arl-sn624x.tplg" to .sof_tplg_filename = "sof-arl-dummy.tplg" to use the function topologies? Same as ptl, lnl, etc.

   Thanks @bardliao — that makes sense.

   We’ll follow your suggestion and update the ASoC ACPI machine match tables to use the dummy topology filenames, e.g.:

   .sof_tplg_filename = "sof-arl-dummy.tplg",
   .get_function_tplg_files = sof_sdw_get_tplg_files,
   (and the same for ptl / lnl / mtl as applicable), instead of adding dedicated sof-*-sn624x.tplg binaries.

   On our validated PTL/WCL platform, runtime already ends up on the SDCA function topologies (sof-sdca-jack-.tplg, sof-sdca-1amp-.tplg, sof-sdca-mic-.tplg). The named sof--sn624x.tplg files were only stubs so probe could find the ACPI default filename. Using *-dummy.tplg should remove that sof/sof-bin packaging need while keeping function-topology selection.

   Plan:

   Send a kernel patch (broonie/sound / ASoC) to switch sn624x sof_tplg_filename to sof-*-dummy.tplg
   Re-validate card probe + playback/capture on our hardware after that change
   Drop the request for new sn624x topology files in this repo / sof-bin
   I’ll post a follow-up here once the kernel change is posted / verified. Unless you prefer otherwise, I think this issue can then be closed as not needing sof topology work.

   Thanks. Sounds great to me. Just remember to re-validate before sending the patch.

   @wangxiaohu2026 Any progress? The sn624x drivers are applied with the monolithic topology.
   There is a new issue reported. thesofproject/linux#6002 It will meet the missing topology issue if we don't change to dummy topology.

   Hi Bard,

   Thanks for the suggestion earlier.

   I've re-validated on a Wildcat Lake (PTL match table) laptop with SN6244:
   with sof-ptl-sn624x.tplg removed, the card probes using function topologies
   (sof-sdca-jack-id0, sof-sdca-1amp-id2, sof-sdca-mic-id4, sof-hdmi-pcm5-id5).
   Speaker / headset / DMIC / HDMI playback and capture work.

   The patch is on linux-sound:

   [PATCH] ASoC: Intel: soc-acpi: use dummy topology for SN624x

   It changes sof--sn624x.tplg to sof--dummy.tplg for MTL/ARL/LNL/PTL
   (Fixes: 32f9c551a91a).

   Please take a look when you have a chance.

   Thanks,
   Qianghua

   When used dummy topology，I fixed one record 4 channels issue：Patch 1 in ucm. ucm2: sof-soundwire: SN624x capture is stereo， Patch 2 in linux kernel（is up stream not be merged）： 0001-ASoC-codecs-sn624x-sdca-limit-DMIC-capture-to-2-chan.patch，these patachs may work on your test.
