Comment 13 for bug 723276

Ok, so it's a problem with fltk-config which lies bundled in the package "libfltk1.1-dev". Apparently this isn't installed as default in 11.04, to fix this, install "libfltk1.1-dev" using synaptic then download alsa-tools from the site suggested by "Patrick le Roux", http://www.alsa-project.org/snapshot/ , open with Archive Manager, open the first folder, up-pack the hdspmixer folder and compile and install it. .)
