January 2026: Delivered DMIC Topology Support for 2-Channel Audio Capture in thesofproject/sof, expanding hardware compatibility and enabling 2-channel capture. Added separated DMIC topologies (SDW_DMIC and PDM_DMIC, 2CH) with dedicated topology files. Commit e19293c118b60f3bb3945153032b1012174393b1 (topology2) adds 2-channel support and topology files for both SDW_DMIC and PDM_DMIC, signed-off by Mac Chiang.

Monthly summary for 2025-10 focused on the thesofproject/sof repository. This period delivered substantial Audio Topology enhancements and expanded multi-codec support, strengthening playback/capture capabilities and cross-hardware interoperability while maintaining maintainability and clear ownership.

September 2025 month-in-review: Focused on stabilizing audio configuration for Fatcat hardware within the qualcomm-linux/kernel-topics repository. Delivered a targeted bug fix to ensure consistent application of machine quirks by using PRODUCT_FAMILY instead of PRODUCT_NAME in the Fatcat series, aligning with Intel ASoC/sof_sdw paths and improving cross-revision consistency.

June 2025 monthly summary for thesofproject/sof. Delivered new audio topology support for the sof-lnl-rt1320-l12-rt714-l0, enabling rt1320 amplifiers on Soundwire links 1 and 2 and the rt714 dmic codec on link 0. JACK codec remains unused; rt1320 AMP_IN capture DAI is unused for this topology. The change is captured in commit 913223387a60f5685024d396fcc86893c7c4ebdf with message 'topology2: add support for sof-lnl-rt1320-l12-rt714-l0'. This work strengthens hardware compatibility, reduces integration risk for new devices, and lays groundwork for expanded testing and validation across SoundWire configurations.

April 2025: Delivered Deep Buffer Speaker Configuration for Topology2 on Intel, enabling a second playback pipeline instance with explicit topology definitions for pipeline IDs, PCM IDs, source and sink paths, and PCM names. Implemented through commit 5359a7f6743e0ea3d878f466c3b063169bcebc7a. Activation and correct configuration validated, improving stability and reliability of deep-buffer playback on Intel hardware.

Month: 2024-11. Focused on expanding topology2 to support a multi-function codec setup with shared SoundWire lanes, enhanced PCH_DMIC capture, and Bluetooth integration for the thesofproject/sof repository. Delivered a critical capability enabling sof-ptl-rt712-l3-rt1320-l3/-4ch configurations and laid groundwork for broader hardware support.
