I tested this kernel here are my findings. 1. Headphones input/output are unplugged by default now
2. When I physically plug it in and select headphones input/output as default, from next plug in it auto switches to headphones input/output from internal input/output and vice versa. 2. Headphones microphone is working fine now, had to set mic boost(seems to be tied to microphone sensitivity) in alsamixer to max to get good sensitivity was set to 0 at first. So, all issues I mentioned above seems to be solved but I have few extra small issues and want to get some insights into it before fully marking this thread as solved. 1. When internal microphone switches to external headphone microphone, internal microphone is still on and keeps picking up compared to internal speakers/headphones output where one or the other is muted automatically. 2. In the legacy driver when earphones/headphones is plugged in internal input/output devices shows as unavailable in pulse audio control and can't be selected in gnome sound settings, in current driver seems like all devices are active and can be switched without unplugging headphones/earphones. I am not sure if this is something that needs to be fixed. 3. I also notice few unplugged hdmi devices in pulse audio control which are not shown when switching to legacy driver. Like HDMI1/DP1 Output, HDMI2/DP2 Output, HDMI3/DP3 Output all of them are shown as unplugged. Also, not sure if this is something that needs to be fixed. If you could provide some insights on these 3 extra issues would really appreciate it.

I will list all of them below and what I have tried so far. 1. Headphones appears always plugged in even if they are physically not 2. When actually plugging in headset/earphones it does not auto switch from speakers/internal mic to headphones/headset microphone automatically and vice versa, have to manually switch everytime. 3. External headset/earphones microphone won't work at all After, logs of trial and error I have found a temporary fix. This seems to use legacy intel drivers which solves all 3 issues mentioned above but the internal/dmic mic is completely gone (which seems intentional when using this). Both depreciated dmic_detect and dsp_driver works, I have been using dsp_driver for now as I need external microphone at any cost. End of /etc/modprobe.d/alsa-base.conf # Headset mic fix options snd-hda-intel dmic_detect=0 / options snd-intel-dspcfg dsp_driver=1 options snd-hda-intel model=alc255-acer In another thread similar to this I got some support and at least fixed the external microphone without using the alsa-base.conf change in custom modified kernel. I will attach it here. Now, hoping to fix other issues as well slowly like making headphones unplugged when physically removing as well as auto switching like the legacy driver one.
