John Joseph (INDIA)
I tried playing a wave file on BF548 EZ-Kit with the 'play' utility and found that the audio output is at times very noisy.
Source used for building the image is release 2008R1.5
Kernel Build Configuration: All default settings except one change. "DMA has priority over core for ext. accesses" has been enabled.
I tried the same on multiple BF548 EZ-Kits and the issue is there on all.
Is there any additional kernel configuration changes required?

There were some fixes we made to the branch, (not in the tarball) with respect to audio.
Do a checkout of the 2008R1 branch.
