Bug description:
[Impact]
We have integrated the alsa sof driver in the oem-osp1 kernel, and
when we tested the hdmi audio function on the docking station, we
found if the machine use sof driver, the hdmi audio on the docking
station can't work.
[Fix]
Intel wrote patches to let sof driver to choose hda hdmi codec
driver, then both hdmi on the laptop and on the docking station
worked.
[Test Case]
ran the kernel with these patches, and in the userspace, we used
the intel updated ucm, then the hdmi audio on the docking station
worked.
[Regression Risk]
Low, Intel wrote the patches and told us to backport these patches.
In addition, we already tested these patches with 4 oem project bugs,
all worked well.
