apport information ** Description changed:
Binary package hint: pulseaudio On Lucid I am finding my sound easily distorts with the volume set to 30% or less. I found a blog post at http://phronetic.wordpress.com/2009/10/30/loud-and-distorted-sound-in- ubuntu-9-10/ and observed that the PCM in alsamixer was always at 100%. I followed the change described in the post and changed: volume = merge to volume = ignore Then restarted pulseaudio and the sound no longer distorts.
