Reverted commit :5e8de9f, issue can't reproduce on CML-H.

Yeah, we need to be more careful with topology changes, we need the matching machine driver to be ready as well, or refer to a PR.

[bardliao]

It should be "fixed" if we remove the SOF_SDW_NO_AGGREGATED flag. But we still need #2539 #2540 or alternative PR to make synchronized playback work.

[tlauda]

@bardliao Are you going to change something in topology or should we move this bug to linux repo?

Can we ignore this issue and #2570 until #2539 and #2540 are merged? I will send a kernel PR to remove SOF_SDW_NO_AGGREGATED after #2539 and #2540 are merged.

[bardliao]

This is due to mismatch between machine driver and topology. It will be fixed by thesofproject/linux#1928

[sinahuang]

Issue can't be reproduced with sof-dev (commit:9b5b6c2a3)+pr1928 and master(commit:d12ad78) .
