I just don't hear them. How do I "purge" alsa-utils and alsa-base? And what does that mean? When playing sound, I hear occasional crackling from my speakers; like a popping sound. The strange thing is that it ran fine at first with Ubuntu dapper (2.6.15 kernel) and after an upgrade to edgy (2.6.17) things are this weird. The thing that worries is me is that when I boot with dapper, things are still weird. Could it be that my sound chip is in some inconsistent state, or should I start fearing that my hardware is failing?
