[GitHub issues - opened]

alsa-project/alsa-ucm-conf issue #424 was opened from DeepHarsora-Dell:

Installed Fedora Rawhide on Dell Latitude 7350 Detachable resulting in no-audio output from onboard speaker and in-built mic (DMIC) can't be detected.

Updated the SUT with the following

1. Topology built rightly.
2. Noticed proper SOF Machine driver in upstream as on v.6.10-rc1, able to load the topology.
3. Updated the UCM2 config files as per [[ALSA_UCM_README]](https://github.com/alsa-project/alsa-ucm-conf/blob/master/README.md)

Below is the error found while alsaucm reload

[linuxengg@fedora ~]$ sudo alsaucm reload
