Workaround allowing proper playing of audio files with different formats
using Pusleaudio.

*For some audio formats that required resampler to be invoked, the
default Pulseaudio resampler (speex-float-N) was not working as
desired and hence no audio was being heard. Changing resampler to
speex-fixed-N allows correct resampling and audio can be heard.
But this is just a workaround since actual issue seems to be with the
toolchain because Pulseaudio source and configuration is same as before
but toolchain has been updated.
A test case is to be developed to cofirm that this issue is related to
toolchain modifications.
