Bug Description
When PCM volume is muted and some audio is playing, I hear noise through front and LFE speakers (or earphones when plugged in). If no audio is playing, I don't hear the noise.
NOTE: that we have been seeing PCM channels becoming muted during updates without user intervention so it is worth checking your Alsa PCM mixer level if you are suddenly getting crackling sound when sound is supposed to be being produced.
Individually muting Master (which control front speakers) or LFE volume, I can't hear the noise. PCM volume controls both front and LFE speakers simultaneously.
