Hi aida,<br /><br />Thank you for taking a moment to review the Samsung HW-C47M Soundbar.<br /><br />I am sorry to hear that you are not completely satisfied with the overall volume of the soundbar. If you don&#39;t have a surround system, you will probably want 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 these tips help you enjoy your new product. <br /><br />You can always contact us for further help at 1-800-SAMSUNG (Ask for Soundbars), 8 AM – 12 AM EST, 7 days a week.
