** Description changed: [Impact] This update adds new ALSA UCM2 profiles to the alsa-ucm-conf package, specifically to enable audio on a range of MediaTek Genio EVK platforms based on the mt8365, mt8370, mt8390, and mt8395 SoCs. This is a crucial hardware enablement update necessary for out-of-the- box audio functionality on these specific development and reference boards. Without these profiles, audio playback, recording, and jack detection are non-functional. [Test Plan] This update requires testing on the specific MediaTek EVK hardware for which the profiles are intended (mt8365-evk, mt8370-evk, mt8390-evk, mt8395-evk). To verify the fix: 1. On a target EVK, install the updated package. 2. Confirm that audio devices (speakers, microphone, headset) are correctly detected in sound settings. 3. Test audio playback and recording through all available devices. 4. Verify that plugging in and unplugging a headset is correctly detected and that audio routes appropriately. [Where problems could occur] Regressions are unlikely but possible on non-EVK platforms if the new configuration files cause parsing issues or introduce unexpected conflicts. This would most likely manifest as a loss of audio functionality (e.g., missing input/output devices) on previously working hardware. - Regression testing can be achieved by running the test plan on any - number non-EVK devices, for example PC. + Regressions are incredibly unlikely on non-EVK platforms. To verify + this: - The checkbox audio/speaker-headphone-plug-detection and - audio/microphone-plug-detection tests can also assist in a non-automated - way. + 1. Examine each of the attached debdiffs + + 2. For each debdiff verify that it only touches files specific to EVK. [Other Info] This update cherry-picks a series of 9 upstream commits that add the UCM2 profiles for the MediaTek EVK platforms.
