I was wondering if anybody was experiencing random cracks and pops (loud ones actually :( ) while using pulseaudio with intelHDA? I have the following configuration for my inbuilt intelHDA card and will be thankful if somebody helped me out here. I haven't observed cracks and pops on my other card (Griffin iMic). I am using pulseaudio 0.9.8 which is able to acquire realtime scheduling priority and a nice level of -11.

I also tried appending fragments and fragment_size options at the end of the intelHDA alsa sink configuration but it still reports "Using 3 fragments of size 19200 bytes.". I was hoping to improve buffering but it seems I am hitting on a bug here. I used to run dmix with my intelHDA running at rate 192000Hz without any problems. Plus, the cracks and pops come using both alsa-pulse and gst-pulse. Thanks in advance for the help. </blockquote><div> I am surprised... *no one* faced this problem? _r </div></div>
