I got my Limited Edition Z10 a few days ago. I found that my app Digital Organ doesn't work properly (making funny noise) on the Z10 but perfectly on the Dev Alpha A and Dev Alpha B.
Could someone with a real Z10 (not the real LE) and Dev Alphas download my app and let me know if it works? I am unable to locate the problem. Thanks a million.
Solved! Go to Solution.

Thanks Peter. That's exactly the problem I got on the Z10.
Now the question is, why are they (Z10 vs Dev Alpha) behaving different? Aren't they supposed to be the same?

There are 4 different variants of Z10 hardware. Three with Qualcomm cpu and Qualcomm’s WCD9310 audio codec and one with TI OMAP cpu and probably with Wolfson WM8994 audio chipset. Also, Dev Alpha and PB implement TI OMAP cpu and Wolfson WM8994 audio chipset.
Both audio chipsets are quite different, in both audio quality and software imlementation.

Thanks to everyone for all the help.
I tracked down the problem. Something seems to be off with my buffer location.

Yes. The Z10 LE requires a much larger frag_size than the dev alphas. Upon enlarging my buffer sizes, the problem disappears. But the problem now is much increased latency. I am not entirely happy with the situation.
