As of commit:
ASoC: soc-core: care .ignore_suspend for Component suspend
function soc-core::snd_soc_suspend no longer ignores 'ignore_suspend'
flag for dai links. While BE dai link for System Pin is
supposed to follow standard suspend-resume flow, appended
'ignore_suspend' flag disturbs that flow and causes audio to break
right after resume. Remove the flag to address this.

we should ask Ben and Curtis @ Google if the changes related to suspend interfere with the wake-on-voice support?
Btw the .ignore_suspend is also set in bytcr_rt5640/51 drivers, so wondering if additional devices are broken, or if there's something off about Broadwell in general. Hans, have you heard of any regressions on Baytrail devices?
I've just tested 5.6.0 on Bay Trail + a rt5651 codec,
using the bytcr_rt5651 machine driver which sets
ignore_suspend, as well as on a Cherry Trail + rt5645
device using the chtrt5645 machine driver which does
_not_ set ignore suspend.
Suspend/resume work fine on both and music playing
before suspend continues playing after suspend.
Note that the bytcr_rt5651 machine driver also does:
snd_soc_dapm_ignore_suspend(&card->dapm, "Headphone");
snd_soc_dapm_ignore_suspend(&card->dapm, "Speaker");
Which the bdw-rt5677 seems to not do...
Regards,
Hans
