libaudio: increase audio buffer size
Bring playback and capture buffer size back to their initial size.
Current size was dictated by constraints in early voice processing implementation
but is not necessary anymore.
Increasing buffer size will help in power consumption and limit possible occurence
of audio skipping during playback and capture.
