The problem is that the "Pink Sardine" (Phoenix) laptops were being applied to the "Yellow Carp" (Rembrandt) driver. This is improper behavior and will cause other problems even if it fixed the immediate microphone issue.
The Phoenix Lenovo laptops are supposed to have something in the ACPI tables that makes sure they bind properly to the Pink Sardine driver, shouldn't need quirks. You *might* be able to workaround the issue until Ubuntu issues a fix by blacklisting snd_pci_acp6x. A Phoenix laptop should be loading snd_pci_ps. -- 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/2062412 Title: No input through internal microphone (Ryzen 6000) Status in linux package in Ubuntu: New Bug description: The microphone in a Thinkpad P14S (AMD) Gen 4 stopped working after updating from 23.10 to 24.04 Beta with kernel 6.8.0-22-generic.
