[pulseaudio-discuss] ALSA lib -> pulse audio -> ALSA plugins-> ALSA driver

[Dspgrp]

Hey,

       I am trying to upgrade pulse audio from 0.9.22 to 2.1 or 3.0 . I am new to pulse audio and somehow not able to make this work. Though my ALSA driver is able to do aplay but Pulse cannot see it . When ever i try to load the module-alsa-sink manually the i get the error with mmap and tsched setting not matching . Can I turn them off from default.pa even though they are enabled in code ? 
                 Also I want to debug why pulse audio is not able to see the sound card . Any pointers would be helpful.

Thanks
Pankaj
