Debra,<br /><br />I am sorry to hear that you are not completely satisfied with the overall volume of the HW-C400 soundbar. You can try to select PCM audio on your TV. You&#39;ll get much louder volume that way, and potentially better sound quality. <br /><br />If your Digital Output Audio Format isn&#39;t set to PCM, for instance if you have a Dolby option selected, then you will likely notice decreased maximum volume. Dolby options are designed for surround systems (like 3.1.2 or 7.1), whereas PCM provides great sound quality for stereo speakers.<br /><br />On a Samsung TV this can be found at Home &gt; Settings &gt; Sound &gt; Expert Settings. (It can also be found in the Quick Settings.)<br /><br />I hope this helps. For further assistance with settings, features, or functions, please contact Samsung Customer Support at 1-800-SAMSUNG, 8AM - 12AM EST (Ask for Soundbars), 7 days a week.
