Very glitchy sound using pulseaudio.

Binary package hint: kdenlive

My sound was very crackly and sometimes delayed when viewing a clip in Kdenlive. I am using Karmic (technically Linux Mint 8) and Kdenlive 4.3.2. This seems to be a fairly common problem in Ubuntu (as suggested by: http://kdenlive.org/user-manual/troubleshooting-and-common-problems/sound-bad-and-delayed) and I found a fix for me on the following forum thread:

See:

I have had some success leaving PulseAudio installed and installing the libsdl1.2debian-pulseaudio package. YMMV. I am not sure why this package is not the default SDL audio backend in Ubuntu:
https://bugs.launchpad.net/ubuntu/+source/libsdl1.2/+bug/203158
https://bugs.launchpad.net/ubuntu/+source/libsdl1.2/+bug/386104

If this works for you, please vote those bugs in launchpad up!"

This made the sound work 10x better in Kdenlive, and if it seems to help with those other bugs in the post too I wonder why the libsdl1.2debian-pulseaudio package is not installed by default.

I suppose it may be relevant that I am using GNOME and not KDE.
