You have been subscribed to a public bug: Binary package hint: alsa-base
I have a Fujitsu-Siemens notebook with a HDA-Intel audio card that I first installed with Feisty Fawn. Since then I have upgraded every half year to the latest Kubuntu release, and DVD playback was never a problem. Now I have upgraded from Karmic to Lucid and when playing DVDs the sound crackles like an old record. When I boot into a backup copy of Karmic again, DVD playback is still fine, so it is not a problem of broken hardware. I have tried doing a fresh install of Kubuntu Lucid using the alternate CD, and the problem also occurs on this fresh installation (the only thing I did after the installation finished was to install the non-free codecs as proposed by the dragon video player in order to be able to play DVDs), so it is not an upgrade problem. This crackling sound only occurs on DVD playback, not when playing mp3 and also not when watching youtube videos. It is independent of the player software: it occurs with dragon as well as kaffeine as well as vlc. The funny thing is that – with all players – the crackle sounds occur every now and then (few seconds) when running the player in windowed mode, but when switching the player to fullscreen mode, the crackling gets so strong that you can barely understand speech. Turning off compositing and desktop effects does not help. Installing "linux-backports-modules-alsa-karmic-generic” and rebooting does not help. Compiling the latest alsa source modules does not help. The sound crackles independent of the volume, so it does not only occur with volume near 100%. “dmesg | grep -i hda“ does not reveal any problem.
