Does the television itself have an internal volume or adjustment? In some cases, the internal and external audio settings can make a difference.
PCM is listed because that's the signal it is receiving. If the source signal changes, it will reflect on the bar.
Hello there. I just purchased a Samsung Crystal Surround Air Track, and have it plugged in via the optical cable into a Panasonic Viera HDTV. I realize that I can't access the visual menu unless I have the system plugged into a Samsung TV, but does that mean I can't access volume controls any other way? I have to turn the system up all the way to get any more volume than I do out of my TV. That, and the subwoofer volume is very very low. It's wirelessly linked to the Soundbar, but producing very little sound. Am I stuck here or is there a way to work around this? Also, the Input Mode is always on PCM. Not sure what that means, but it won't let me change at all. Is there a way to fix this? Please help, thanks very much!
