Dave W. from Kaysville asked:
I have a blu ray player in my basement hooked up to a plasma tv with a surround sound system. For some bizarre reason the audio works on some blu ray discs and not on others although it has worked just fine on these same discs before. What do you suggest?
Hello Dave and thank you for your question.
Troubleshooting from afar is sometimes difficult, but I think we can talk you through it. First off, there are a couple of things I would investigate. Do the problem blu-ray discs play in other machines now? Perhaps a friendly neighbor could oblige and determine. The real culprit probably has to do with which audio track is being played. Per Wikipedia (said better there than if I tried): Players are required to support Dolby Digital (AC-3), DTS, and linear PCM. Players may optionally support Dolby Digital Plus and DTS-HD High Resolution Audio as well as lossless formats Dolby TrueHD and DTS-HD Master Audio. Now back to me. Some of the formats can play using an optical digital cable, whereas the newer formats require an HDMI cable. Additionally, some of the formats aren’t recognized by older players. The good news is that the good ‘ole Dolby Digital 5.1 format is available to play, the trick is getting your player to play it. When you look at the menu for a disc you will probably see Audio choices. Try selecting the Dolby 5.1 instead of the 7.2 or Master Audio. One other item to consider is to update the player’s software. Most blu ray players “like” to be hooked up to the Internet. That way when new formats and functionality emerges they can update the software to accommodate. I would recommend doing this also, just on the off chance you are playing a new disc with an older software. My money is on the audio format issue though. Give it a try and let us know. If those quick items don’t work, give us the model numbers of both the blu ray player and the surround sound system along with the blu ray disks in question and we’ll do some digging GTK.
Thanks again for asking the Guys That Know!
