In answer to my own question. I went into sound settings on my Sony Bravia TV and changed highlighted TV speakers to external speakers and also changed the setting that said originally A instead to stereo. Played a track that I had trouble with before and it played perfectly ,no fluctuation.
I bought some Creative labs t20 speakers to go with the Bravia and wd hdtv after reading many good reviews about them. They are fantastic giving very good sound and are quite small. They connect via the headphone jack if needed.
