Hi Arun,

Yes, When I use tsched=0 in default.pa, getting low delay but the audio 
quality is not good as compared to the previous audio(audio with delay). 
I am getting audio with noise(I think extra noise sample added with 
audio). I have tried with kernel Version: 2.6.35 & 2.6.38, in both case 
results are same.

I tested same usb mic on laptop and its working fine without any delay 
problem, also tried USB mic with usb headset(playback sink) on 
pandaboard but delay still persists.

Please help to figure out where is the problem.
