Well, there is one issue still in here. When I do use both `snd_intel_dspcfg.dsp_driver=1 snd_hda_intel.model=alc255-acer` kernel parameters:
1) VERY BAD: there is no mic available in sound settings :( 2) GOOD: when I connect something into audio jack, an overlay asking for device type pops up - letting me to select whether it is headphones only or headset When I do use just the `snd_hda_intel.model=alc255-acer` kernel parameter or no parameter at all (just defaults): 1) GOOD: both mics work 2) VERY BAD: there is cracking in headphones every couple of seconds whenever there is no audio playback active after changing the volume level - it feels like if it's turning on and off in a cycle… it stops, eventually, but its very annoying, especially if speakers are connected. It is the very same sound as it does by turning on the laptop. 3) BAD: no device selection popup PS: In any case, I am still using also `pci=nocrs`, because I have to due to this issue https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1884232 -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
