[PATCH] src/pcm/pcm_ladspa.c: Delay LADSPA plugin activate call

[Matthias Larisch <mail@matthias-larisch.de>]

[-- Attachment #1.1: Type: text/plain, Size: 1342 bytes --]

Some LADSPA Plugins rely on connected control ports on activate call.
While this is not okay by spec, the spec also encourages the activate
call happening as late as possible.
