@Marian,

After read the https://github.com/thesofproject/linux/issues/2700, looks
like the kernel 5.11 couldn't work on your machine. So please use the
5.13 kernel built on your won, and wait for the mainline build kernel to
merge this kconfig fix.


And for the sof-firmware and alsa-ucm-conf, could you please replace the needed 
files little by little, then find what files must be upgraded to support your 
machine. like:

/lib/firmware/intel/sof/*.ri?
/lib/firmware/intel/sof-tplg/*.tplg?
/usr/share/alsa/ucm2/sof-soundwire/?

Title:
  build module CONFIG_SND_SOC_INTEL_SOUNDWIRE_SOF_MACH=m for 5.11,
  5.13-rc2 and later

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Hirsute:
  Fix Committed
Status in linux source package in Impish:
  Confirmed

Bug description:
  [Impact]
  Ubuntu users ran the kernel on the Dell soundwire audio machines,
  the dmesg shows the audio mchine driver is not found, then the
  audio fails to initialize

  [Fix]
  Enable the intel soundwire audio machine driver and some related
  codec driver.

  [Test]
  run fakeroot debian/rules clean updateconfigs, and check the
  config.common.ubuntu, the content is not changed.
  Build the kernel with this patch applied, the soundwire audio
  machine driver is built.

  
  [Where problems could occur]
  This could possibly introduce the building failure, I tested it,
  so far no failure.

  Default kernel from
  https://cdimage.ubuntu.com/kubuntu/daily-live/20210327/
  and also upstream kernel
  https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.12-rc4/

  tested and both do not work.
