Yes, in new 217 build these 2 problems is gone, but I've experienced some new trouble:
When I play Mono
OGG file on PocketPC the speed of playback is doubled on all frequencies of OGG or audiosystem of program, with Config::bAudioStereo set true / or false.
When I play Stereo OGG file there is all ok.
In WinXP project I could fit some settings when frequency of engine sound system was 2 times lower than OGG file, and again with stereo file there was all normal and good.
