Comment 5 for bug 2017832

Attempted a variety of things that I found on the internet for similar problems:

Various options to alsa-base.conf (tried them individually):

/etc/modprobe.d/alsa-base.conf
    options snd-hda-intel model=auto
    options snd-hda-intel model=generic
    options snd_sof sof_debug=128
    options snd_sof sof_debug=1
(also tried the last 2 in /etc/modprobe.d/sof.conf)

Tried these via grub and also via alsa-base.conf options

   GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_hda_intel.dmic_detect=0"
or
   GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_intel_dspcfg.dsp_driver=1 (and/or with different values, 0-3)

No improvement with any of these experiments.
