Takashi --- a/sound/pci/intel8x0.c +++ b/sound/pci/intel8x0.c @@ -694,7 +694,7 @@ static inline void snd_intel8x0_update(struct intel8x0 *chip, struct ichdev *ich int status, civ, i, step; int ack = 0; - if (!ichdev->prepared || ichdev->suspended) + if (!(ichdev->prepared || ichdev->in_measurement) || ichdev->suspended) return; spin_lock_irqsave(&chip->reg_lock, flags);
