** Description changed: + The patch was merged to ubuntu 5.13.0 and 5.11.0 generic kernels + with stable update already, but it is not merged to ubuntu 5.4.0 + kernel yet, so I sent this SRU for the focal kernel. + + [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.
