a788b7e747 PcmConvert: fix src_format corruption when converting from DSD 
Method PcmConvert::Convert() modifies the src_format variable.  This
used to be a parameter, however commit d2679f59c made it an attribute
instead.  The modification to src_format persisted, and the next call
would return garbage.

105b431e4c PcmBuffer: reset size in Clear() 
Fix for Mantis #3806.

"PcmBuffer::Clear clears the buffer but does not reset the size. If
Get is called on the same PcmBuffer later on with a size that is the
same as (or less than) it was before the call to Clear, the "else"
branch is taken and the memory of buffer (at the address of nullptr)
is poisoned instead of the necessary allocation being performed. A
memset or memcpy on the returned pointer (nullptr) causes a
segmentation fault."
