I see. Thank you!

But I have further questions:

* Do I need USE_RTC for better accuracy to eliminate the delay problem?
* Do I need kernel >= 2.6.13 to enable USE_RTC ?


I have also tried patch from bug 4252 (app_meetme-HEAD.diff).
But the audio quality degraded evidently, while the delay problem
still existed... Sigh...
