Reverted commit :5e8de9f, issue can't reproduce on CML-H.
plbossart commentedon Mar 18, 2020
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 commentedon Mar 19, 2020
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 commentedon Mar 19, 2020
@bardliao Are you going to change something in topology or should we move this bug to linux repo?
bardliao commentedon Mar 19, 2020
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 commentedon Mar 24, 2020
This is due to mismatch between machine driver and topology. It will be fixed by thesofproject/linux#1928
sinahuang commentedon Mar 24, 2020
Issue can't be reproduced with sof-dev (commit:9b5b6c2a3)+pr1928 and master(commit:d12ad78) .
