** Changed in: hwe-next
Status: New => Fix Released
** Summary changed:
- audio card disappeared after suspend device during audio playback Edit
+ audio card disappeared after suspend device during audio playback
** Description changed:
[Impact]
- audio card disappeared after suspend device during audio playback Edit
+ audio card disappeared after suspend device during audio playback
[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, 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.
