I had audio issues after the installation of LM20.1 on a brand new Dell Inspiron 15 3000.
The loudspeaker were not working at all, I could solve this by adding the option ="snd-intel-dspcfg.dsp_driver=1" into GRUB_CMDLINE_LINUX_DEFAULT of the etc/default/grub file.
The sound is working / the hardware is detected some seconds after logging in (but not directly) but this is not my real issue.
The other issue is the internal microphone which is not detected (the headset works). I tried several solutions found on this forum and other ones but none seemed to work for me.
I would be glad to find some help!
Thanks a lot in advance!
