Subject: UCM2: Intel: sof-hda-dsp: HiFi: Fix handling of mono DMICs
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=56cbdfd04339cf9598cd9d57f5c1a382504ae902;p=alsa-ucm-conf.git

UCM2: Intel: sof-hda-dsp: HiFi: Fix handling of mono DMICs

When a single DMIC is present in the system we need to set the
CaptureChannels to 1 since the PCM device only supports mono, PA/PW will
reject the profile since it cannot open the DMIC PCM device.
