Why is sound only coming from some speakers on my Samsung Home Theater System?
When listening to a CD or radio, sound is often output only to the front speakers. To use all six speakers, select the “PRO LOGIC” option by pressing the Pro Logic button on the remote. Also, verify that your DVD disc is 5.1 CH compatible.
Why is the sound quality irregular on my Samsung HT-DM150?
Check the speaker cables to ensure they are not loose. Also, inspect the speaker connectors for any dirt or debris.
Why is there no sound coming from my Samsung Home Theater System?
Several factors could cause a lack of sound. Note that no sound is produced during high-speed, slow, or step motion playback. Check if the speakers are properly connected and the speaker setup is correctly customized. Also, inspect the disc for severe damage or dirt, and clean it if needed.
Why is Dolby Digital 5.1 surround sound not working on my Samsung Home Theater System?
If Dolby Digital 5.1 Channel Surround Sound isn't being reproduced on your Samsung Home Theater System, confirm that the disc displays the “Dolby Digital 5.1CH” mark, as 5.1-channel sound is only available if the disc is recorded with it.
