with our large voice file being loaded in its entirety to the buffer there isn't enough room to allocate the required pcm buffer well prior to this patch we looked for 1k free to allow the talk buffer to be given away well the pcm buffer expects something like 5-600 kb on the clipzip and there is 1k allocatable but not 300 more so instead get the required pcm buffer size and check against that Change-Id: I40a056e4170c37bc3429f0cb37af221ae7f812e5
