Some systems (especially budget laptops) utilizes a DSP shipped with
the CPU for connection with the audio codec. The Sound Open Firmware
must be loaded onto the DSP to make it functional. These firmware
files can be downloaded from
<ulink url='https://github.com/thesofproject/sof-bin/releases'/>.
Extract the tarball and changing into the extracted directory,
then as the &root; user install the firmware:

<xref linkend="alsa-lib"/> needs Use Case Manager configuration files
for the systems using Sound Open Firmware as well. The ALSA UCM
configuration files can be downloaded from
