[BUG] Internal speakers not working on Lenovo Yoga Aura Edition (LNL + CS42L43 + CS35L56x6)
I'm running Zorin OS 18 (based on Ubuntu 24.04) on a Lenovo Yoga Aura Edition with Intel Lunar Lake. Headphones work perfectly, but internal speakers do not produce sound. The SOF driver loads successfully, and the CS42L43 codec is detected, but the speaker widget never binds.
I've tried overriding the topology with every available .tplg file from the latest SOF bundle, including:
sof-lnl-cs42l43-l0-cs35l56-l3.tplg
sof-lnl-cs42l43-l0-cs35l56-l3-2ch.tplg
sof-lnl-cs42l43-l0-cs35l56-l23.tplg
sof-lnl-cs42l43-l0-cs35l56-l23-2ch.tplg
sof-lnl-cs42l43-l0-cs35l56-l23-4ch.tplg
sof-lnl-cs42l43-l0-cs35l56x6-l13.tplg
None of these result in speaker widget binding. The only relevant log line is:
Code sof_sdw sof_sdw: Setting CS42L43 Speaker volume limit to 128 No errors, but no speaker output either.

Request:
Could you confirm whether this layout is supported? If not, is there a matching .tplg file or patch available for this configuration?
Thanks in advance for your help!
