The initial buffer allocated for the Audio PD memory pool is never added
to the pool because pageslen is set to 0. As a result, the buffer is not
registered with Audio PD and is never used, causing a memory leak. Audio
PD immediately falls back to allocating memory from the remote heap since
the pool starts out empty.
Fix this by setting pageslen to 1 so that the initially allocated buffer
is correctly registered and becomes part of the Audio PD memory pool.

If it's From:Ekansh, it can't be CDB: Ekansh. How can Ekansh co-develop
the patch with himself?
I will delete CBD:Ekansh.
