Sample rate set from ogg demuxer differs from one set in libspeexdec. So look for changes in libspeex decoder.

This was broken by 3b061c5e10f78caaf3b2a45cf7a92e50d4d20bfb which changed the code to ignore the sample rate specified in the speex header for no good reason at all and without mentioning it in the commit message.

You definitely expect far too much;-)
