Bug Description

Since updating the package from 1.2.6.3-1ubuntu1.9 to 1.2.6.3-1ubuntu1.10, when playing audio from a speaker connected over HDMI, using the default stereo audio preset adds the sound of sand to the audio being played. Switching to the 5.1 audio preset fixes the issue.

In case it's relevant: My HDMI port is connected to an NVIDIA GPU, which is the dedicated GPU in the laptop.
