[LAD] Handling multiple audio streams [was: Adding a c timer to Kluppe]

Hi, Just in case anyone has had some time to ponder this problem and has forgotten to respond or missed the original request for assistance. I would like to add a timer function to kluppe so that I can add a timed delay to the playback start for an individual loop. There are a couple of problems with the current implementation. 1: There is an annoying buzz when the loop is paused on three out of four pause scenarios. This is probably related to the buffer being trapped on pause for some reason. 2: With the current implementation using select(), the pause affects all running loops. I tried to work asynchronously with signal and alarm() but that was suggested as the wrong method. Now I am out of my depth as I am not sure how to create an asynchronous timer in c that will apply to the kluppe system. For example in some other languages there are timers and example code already written for this problem which makes it a fairly simple procedure to implement. Perhaps there is also something fundamental with the kluppe code that makes this problem even more difficult. If someone has a suggestion for the correct way to handle this problem I am more than happy to code it up and learn something new but I am aware that if I have to figure this one out by myself it's gonna take some time. The current test code is here: http://djcj.org/code/kluppe-0.6.14-playbackdelay.tar.bz2 The core code can be found at src/common/looperdata.c:1342 To enable the timed playback pause you need to adjust the bottom right spinbox in the spinbox grid panel for a specific loop.
