You have a parent PCI device and a set of child devices for each manager. The parent PCI device cannot suspend before all its children are also suspended, so shouldn't the delay be modified at the manager level? Not getting what this delay is and how this would deal with a lengthy enumeration/initialization process. > > Signed-off-by: Vijendar Mukunda <Vijendar.Mukunda@xxxxxxx> > --- > sound/soc/amd/ps/acp63.h | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/sound/soc/amd/ps/acp63.h b/sound/soc/amd/ps/acp63.h > index 833d0b5aa73d..6c8849f2bcec 100644 > --- a/sound/soc/amd/ps/acp63.h > +++ b/sound/soc/amd/ps/acp63.h > @@ -51,7 +51,7 @@ > #define MIN_BUFFER MAX_BUFFER > > /* time in ms for runtime suspend delay */ > -#define ACP_SUSPEND_DELAY_MS 2000 > +#define ACP_SUSPEND_DELAY_MS 3000 > > #define ACP63_DMIC_ADDR 2 > #define ACP63_PDM_MODE_DEVS 3
