I see you don't have much experience in emailing, because you're
always topposting, which makes reading your answers somewhat
terrible.

Increasing the watermark is responsible for laaging your sound
output. Please notice, that alsa-sink.c is a file of the pulseaudio
source package. Please point me to the possible reason if I am
wrong.

Hmm, but not that lagging. As said before on my AD1984 chipset all
sounds well. Maybe you customized your pulseaudio setting in a wrong
way? For testing you should purge all pulseaudio packages, check
lagging and syslog and come back with the error infos to this
bugreport. Don't forget to backup your pulseaudio settings before.

This is a way of sensefull debugging.

Did you tried that as well?
