I do have the request output connected back into the Soundreader. I have noticed on two music files that the playback is slowed and the pitch a little lower. The mp3 loops back to the beginning when it is only partially completed. Any suggestions. One of the MP3s is about 7.5 megs and has a playtime of 4.5 minutes. Is loops after about 45 seconds. Thanks Georeg

You need to set those properties (sps) the same in both elements (should be also the same as the sps the sound was recorded with). The other problem is because of caching (there is an error about it on console). You need to set NO CACHE.
