I've made a new test, currently on POPOS 21.04, kernel 5.13: ❱ uname -rv 5.13.0-7614-generic #14~1631647151~21.04~930e87c-Ubuntu SMP Fri Sep 17 00:24:58 UTC
1) default boot options: ======================== - internal mic works, external not 2) changed to intel_dspcfg.dsp_driver + headset-mic: ======================== ❱ cat /proc/cmdline initrd=\EFI\Pop_OS-a99686bf-c48a-464b-af3a-25f67847049a\initrd.img root=UUID=a99686bf-c48a-464b-af3a-25f67847049a ro snd_intel_dspcfg.dsp_driver=1 snd_hda_intel.model=headset-mic - neither mic works 3) changed to intel_dspcfg.dsp_driver + alc255-acer ========================= ❱ cat /proc/cmdline initrd=\EFI\Pop_OS-a99686bf-c48a-464b-af3a-25f67847049a\initrd.img root=UUID=a99686bf-c48a-464b-af3a-25f67847049a ro quiet splash snd_intel_dspcfg.dsp_driver=1 snd_hda_intel.model=alc255-acer - external mic is now working (!), when jack is plugged-in, it corerctly asks what device have I connected (headset or headphones?) - internal mic is not working, though :( 4) it (does not) works with pci=nocrs, too: ================================ ❱ cat /proc/cmdline initrd=\EFI\Pop_OS-a99686bf-c48a-464b-af3a-25f67847049a\initrd.img root=UUID=a99686bf-c48a-464b-af3a-25f67847049a ro quiet splash pci=nocrs snd_intel_dspcfg.dsp_driver=1 snd_hda_intel.model=alc255-acer So, this solution is not very practical, because when I do not have headset available at the moment, I cannot use internal microphone :( -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1912052 Title: [Acer Spin 5 - SP513-54N] External headset microphone not working on Ubuntu 21.04 (not even wired, cable headset) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1912052/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
