Thanks for the info I think I got it, these 3 are really not issue just minor inconvenience. I can adapt to it no problem.
1. For first issue can just mute internal dmic microphone when not in use since I almost never use it so permanently mute. 2. For second issue of splitting input/output sources even windows does the same for this laptop so it's normal I think. 3. Not sure about the third hdmi output devices, but since they are unplugged should cause no problem, I even had found a way to remove these once but lost the article. I also forgot to mention one more issue the internal speakers and external headphones are sharing the same volume in current driver even with modified kernel above (legacy driver has different volumes), changing one and switching to other changes switched one volume as well, maybe this could be fixed? Also, I am not knowledgeable about how these fixes reaches official ubuntu kernels and how much time could it take. I will keep using temp fix till these fixes arrives in official kernel. If I could get some information about these would be helpful as well. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1930188 Title: Acer Aspire 5 sound driver issues Status in linux package in Ubuntu: New Bug description: 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.
