** Description changed: - this bug is for tracking. + [Impact] + We need to enable a Dell soundwire machine in the OEM project, but + the soundwire design is different from previous generation, it follows + soundwire sdca spec. both ubuntu kernel and upstream kernel don't have + driver for soundwire sdca yet, so the audio device on this machine + can't be detected. + + [Fix] + backport 20 patches from the kernel git tree of intel sof/project + + [Test] + After booting up, we could see the sound card by running + pacmd list-cards, and there is speaker, headphone, dmic and headset-mic + on this sound card, test playback and record, all worked well. + + [Where problems could occur] + The patches change some soundwire bus driver and alsa intel asoc + machine driver, it could make the sound stop working on old + soundwire machines. But this possibility is very low since we + tested these patches on Dell soundwire machines.
