Calling prepare() on a stream which is already active shouldn't touch the sample pointer positions. This code belongs into the trigger callback, so move it there.

shouldn't touch the sample pointer positions. This code belongs into the trigger callback, so move it there.
The trigger callback should execute as fast as possible; any initialization that isn't need to directly start the stream should go into the prepare callback.

You're right, thanks for the heads-up. It was indeed a bug in a different part of my driver which only affected the newly added model it supports. I was increasing the periods counter for inactive streams, which confused the ALSA core.
Forget about this one, I'll repost a new series in a second.
Thanks, Daniel
This patch adds support for the new Traktor Kontrol S4 by Native Instruments. It features a new audio data streaming model, MIDI in and out ports, a huge number of 174 dimmable LEDs, 96 buttons and 46 absolute encoder axis, including some rotary encoders.
All features are supported by the driver now.
Did some code refactoring along the way.
