Thanks Renato. But what I'm trying to do is use the "Script" in Setup to make QjackCtl automatically load a certain preset without me having to do it. The reason I want to do this is because: 1) I have QjackCtl set to start automatically on system startup and I also have QjackCtl set to "start jack server" straight away when loaded. At the moment it automatically loads the last preset used, so if I've been using "firewire" and then I shut my computer down, when I start it again QjackCtl loads automatically and tries to load the "firewire" driver/preset even when the firewire isn't connected, so I get loads of error messages. And 2) whilst studying the options in QjackCtl (I'm new to Linux audio and excited) I noticed that there seems to be the facility to make it load specified presets automatically and I wanted to try it, but it doesn't seem to work and I don't know if I'm getting the "meta-symbol arguments" right (I'm totally new to them).<br>
<br>This relates to an earlier request/thread I made in LAU. It's not a big deal if I can't do this as it just means I need to always remember to manually switch QjackCtl to my "alsa" preset whenever I turn my firewire device off so that it doesn't ever try and load "firewire" when the device isn't there, like you said. I just hate error messages and I like automation - some kind of Obsessive Compulsive thing I have maybe ;). It just seems like QjackCtl offers an easy solution to my problem and I'm not using it right.<br>
