[Impact] Users plug headphone and Mic to the audio jacks, but the system can't detect them, and couldn't output sound through headphone and record sound through Mic. [Fix] Backport a upstream patch, this will set the Mic to auto-detection mode and set the headphone to left location. [Test] Plug a headset to the headset audio jack, both headphone and mic could be detected. And output the sound to headphone, could hear the sound, record the sound through Mic, the sound could be recorded. [Where problems could occur] The patch is specific to Acer Aspire 5 machine, if it could introduce regression, it will make the audio like internal mic and internal spk stop working. But this possibility is very low. Hello, There seems to be lots of issues in sound driver for Acer Aspire A515-56-57XR with ALC255. 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.
