First of all...sorry my english.

I have a HTS5120/55 Soundbar. Its conected to PS3 and Sony Bravia, and the experiencie is very bad.

I connected the soundbar via HDMI, component and TOSLINK (optical). The subwoofer has an intermittent sound. As a pounding, very noticiable when the people just talking in the movies, for example. By the other hand, sometimes the sound disappears for a moment (1 or 2 second) and then is possible to hear the audio again.

The Soundbar has the firmware version 1.5s, the latest.

Please let me know. Thanks from Chile.
