While developing an application that uses advanced sound techniques, I've noticed several problems:
- The get channel/sample frequency expression is not supported despite the fact all actions related to frequency are supported
- It's impossible to play the same sample at two or more different channels at the same. The only workaround I've got to work outside of the standard Windows runtime is to use a different clone of the sample for each channel, which obviously is a dirty hack.
- It seems that once a channel volume drops below a certain threshold it's considered muted despite being above zero. It creates an ugly artifact when fading in/out samples.
