Hi,

I am working with DM368 based custom board. we have external codec interfaced to McBSP. when we run aplay command i am observing memory leak.

the leak is around 12k everytime i do aplay. if i get any underruns the leak is more than 12k

the kernel version i am working is "Linux-2.6.32.17-davinci1".

The codec driver is in alsa model. Could you please help to resolve this problem.

Thanks in advance, Sreedhar.
