But snd_soc_dapm_new_widgets also calls dapm_power_widgets which operates on the passed dapm_context, will it be without any effect on the DAPM context, when it is called on a newly allocated context?
Yup.
Otherwise I would say call snd_soc_dapm_new_widgets once for the cards dapm_context and snd_soc_dapm_sync for each codec context.
There's no point in repeatedly syncing - it may cause audible issues if we power things off due to incomplete information. If the sync isn't propagating over the entire system we should fix that.
