Recently I bought Infinix Y4 Max laptop and replaced the preinstalled Windows with Ubuntu 22.04. Everything is working fine except the internal speaker (also fast charging is not happening but that's not much of an issue) but audio is working fine from headphone jack. It shows Speakers (unavailable) in audio settings. Currently it's on Linux 6.5.0-15-generic x86_64 kernel. I used alsamixer to change volume and mute/unmute and hdajackretask to change unconnected pins or whatever that is, still no success. I googled and check many pages related to this codec but no solution helped in my case. Would could be the reason for this issue? speaker worked fine in windows tho.
all the system information is in this link. https://termbin.com/mhzu
Partially solved
After going through this page and some trial and error and I find out that adding options snd_hda_intel model=dell-inspiron-7559 at the end of /etc/modprobe.d/alsa-base.conf works better for my laptop. The internal speakers are working now but the headset microphone are not. I tried many model code and figure out that with alc288-dell1, alc288-dell-xps13, alc298-dell1 and alc298-spk-volume, the headset microphone are working but internal speakers are not. So either internal speaker will work or headset microphone.
