Argh, seems the kernel I'm using doesn't have the debug options. Any other ways around this?
Check the system log whether the hwptr position are correct in first nine periods and xrun occur on 10th period since the buffer contain 9.27 periods when running vlc?
Which system log? Or maybe this is related to the above? I can't find anything in any file under /var/log/ that contains anything you're talking about.

Does it support 4 and 6 channels in windows ?
6 channels. I don't use more than 2 channels anyway.
