Did you already try > the patch below? The click seems associated to some residual samples inside the buffer. Here it is a sample of the king of click noise I'm hearing here (captured from CD input entry): http://linuxtv.org/~mchehab/snd.ogg I've started/stopped the CD some times (with cdplay). When volume goes to zero, after an "echoed click", it disappears. I've did some trials with position_fix changes, but nothing solved. So, my previous patch were wrong. The click is somewhere else (still, I suspect that it is linked to the buffer handling).
