ATI SB4x0 doesn't need any fix at position.
It's not about the position fixing but whether to use the position-buffer. The devices on the blacklist are the ones that have no position buffer. So, it would fall into LPIB mode, and this list avoids it from the beginning.
This patch solves the issue of receiving several clicks during capture on those devices.
Tested with a Gateway Notebook MX-6453.
The click noise is often a different problem. 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 didn't check the ogg file yet, and just a wild guess)
Is it with dsnoop plugin? With "default" PCM, ALSA uses dsnoop for capture to allow multiplexing for HD-audio. Does it happen with "hw" or "plughw" PCM?
