[linux-audio-dev] help with writing a plugin (part 2)

Dear friends, thanks again for your help with my ports definition yesterday - with it, I created a clipping booster plugin with three control ports and it works perfectly. However, today I added the fourth port, following all rules I learnt, but I get the same segfaults as yesterday. If you could have a look at the sources (attached), it would be of fantastic help for me. Once again, please forgive me, I am a real newbie at this and things that are very obvious for you are not such for me... But as I understand all these bells and whistles, I will be more silent ;-) Thanks a lot again. Regards, Artemiy.
