Public bug reported: [SRU Justification]
[Impact] On Dell's platform, Warlock/Bullseye Laptops have a mono DMIC, Cyborg and some Warlock variants uses a stereo DMIC. They are not correctly mapped to the corresponding configurations so the microphone function are not working as expected. [Fix] Cirrus upstream new FIXUPs to support different microphone configurations on different Dell laptop variants. [Test Case] 1. Go to Audio Settings 2. Make sure the microphone is correctly detected and responds to audio input. 3. Issue command "arecord record_file" and check the record_file is consistent with audio input. [Where problems could occur] Risk should be Low. The patches come from Cirrus and the configurations are mapped based on the audio codec's SSIDs for different Dell variants. ** Affects: linux (Ubuntu) Importance: Undecided Status: In Progress ** Affects: linux-oem-5.14 (Ubuntu) Importance: Undecided Status: New ** Affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Affects: linux-oem-5.14 (Ubuntu Focal) Importance: Undecided Status: In Progress ** Affects: linux (Ubuntu Jammy) Importance: Undecided Status: In Progress ** Affects: linux-oem-5.14 (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: linux-oem-5.14 (Ubuntu) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: linux-oem-5.14 (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux-oem-5.14 (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: linux-oem-5.14 (Ubuntu Focal) Status: New => In Progress ** Changed in: linux (Ubuntu Jammy) Status: New => In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1967988 Title: Support different Cirrus audio codec configurations on Dell laptops To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1967988/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
