ALSA: scarlett2: Fix line out/speaker switching notifications
The values of the line output controls can change when the SW/HW switches are set to HW, and also when speaker switching is enabled. These notifications were sent with a mask of only SNDRV_CTL_EVENT_MASK_INFO. Change the notifications to set the SNDRV_CTL_EVENT_MASK_VALUE mask bit as well. When the mute control is updated, the notification was sent with a mask of SNDRV_CTL_EVENT_MASK_INFO. Change the mask to the correct value of SNDRV_CTL_EVENT_MASK_VALUE. Signed-off-by: Geoffrey D.
