Comment 3 for bug 84900

This is confirmed for Feisty. In Edgy, this package did include the output plugin that allows ALSA to output to JACK, but that has gone missing. Any reasons (other than not wanting to force people to install JACK??). For those of us who use JACK as a primary audio interface, this plugin is an absolute necessity for applications that do not natively support JACK.

Furthermore, the package text description still says the package includes support for JACK, despite that being removed. This is potentially very confusing for new users.
