The upstream commit of a newer version usually include the topology files for the new platforms or missing configuration on old platforms. It would be better to catch up with upstream to have these configuration which can support more configurations we could be missing in the future. This firmware-sof patch includes the New DSP topologies added in v.2.12 which is formally released in https://github.com/thesofproject/sof- bin/releases and signed by Intel.
Although there're lots of new tplg files added, but they are mostly for missing configuration on old platforms or newly added for next-gen Intel platform. And they are specified for particular soundwire configurations which can hardly affect the existing machines. It should help reduce our efforts to support different audio configurations coming from more vendors and machines. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2106394 Title: [SRU] enable cs42l43 and cs35l56 audio on Intel LNL Status in HWE Next: New Status in alsa-ucm-conf package in Ubuntu: Fix Committed Status in firmware-sof package in Ubuntu: Fix Released Status in linux package in Ubuntu: New Status in linux-firmware package in Ubuntu: In Progress Status in alsa-ucm-conf source package in Noble: Fix Committed Status in firmware-sof source package in Noble: Incomplete Status in linux source package in Noble: Won't Fix Status in linux-firmware source package in Noble: Fix Committed Status in alsa-ucm-conf source package in Oracular: Fix Committed Status in firmware-sof source package in Oracular: Incomplete Status in linux source package in Oracular: Fix Committed Status in linux-firmware source package in Oracular: Fix Committed Status in alsa-ucm-conf source package in Plucky: New Status in firmware-sof source package in Plucky: Fix Released Status in linux source package in Plucky: New Status in linux-firmware source package in Plucky: New Bug description: [Impact] No audio input/output for cs42l43 and cs35l56 on Intel LNL of ThinkPad.
