** Description changed: [Impact] audio card disappeared after suspend device during audio playback Edit [Fix] Set trigger order for FE DAI links to SND_SOC_DPCM_TRIGGER_POST to trigger the BE DAI's before the FE DAI's. This prevents the xruns seen on playback pipelines using the link DMA. - [test] - With the patch, mantis n5 14 could be suspended successfully and + With the patch, machine could be suspended successfully and ALSA device still presents after leave suspension. [Regression Potential] Low. If some DSPs need the reverse order(FE->BE), we may get the same error.
