What's the reason for the switch (or is is a bug)? Hi! The pcm buffer low watermark level was increased because some people were reporting problems that pcm buffer goes empty on certain situations. Now I have decreased the level much and I hope the current setting would prevent these problems from happening. However, if crossfade is enabled we need to keep the buffer always as filled as possible.
