Dear maintainers of the wavesurfer and libsnack2 packages, I am one of the contributors to wavesurfer and work in the lab where both wavesurfer and snack were developed.
I am writing to both bug threads because I think we need some coordination in order to solve this problem. In http://bugs.debian.org/659974 it is said that this is not a urgent issue because not many people complained. I can tell that this bug affects a whole faculty at KTH, Stockholm where I work and use wavesurfer as a teaching tool. The way we solved the issue is to install a binary version of wavesurfer outside the apt-get system, which is far from optimal. >From the threads http://bugs.debian.org/659974 and http://bugs.debian.org/567713 it is not clear if any decision has been reached, yet. I believe the correct way, as has been suggested already, is to have wavesurfer depend on libsnack2 (without version) and make libsnack2 a virtual package provided alternatively by libsnack2-alsa or libsnack2-oss. However you decide to solve the issue, please do this as soon as possible, because it affects more users than you think. Thank you for your help, Best, Giampiero
