Ah I know why your internal mic doens't work, it is a new HW design, the internal mic is connected to PCH instead of codec, so it needs sof driver and firmware/tplg/ucm to work. But so far, we don't have them for Xiaomi.
We only have some files which are specific to some dell machines and lenovo machines. this is a similar bug to https://bugs.launchpad.net/ubuntu/+source/alsa- driver/+bug/1852922 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1846148 Title: Realtek ALC256M with DTS Audio Processing internal microphone doesn't work on Redmi Book 14 2019 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1846148/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
