PCM, Stereo, etc. From USB it can send 5.1 or such and soundbars are almost always stereo. Yes some write 5.1 but that's been kicked around a lot. Let's be sure we are sending what the bars have (2 speakers = stereo.)
I'm posting on the chance someone knows right off what this is, and maybe to help anyone else searching for it.
I have the UN48H5500 (2014 model) TV. Right now i'm using a toslink cable (optical with red light) going from the TV to the soundbar. Sound works great unless I want to stream or play videos via a USB drive. If I hook directly to the usb on the tv it won't allow sound to the soundbar.. however if I hook it to the Blu Ray via usb, sound is fine.. so it's not the cable... something, some setting on the TV isn't allowing audio this way. I was thinking trying the 'audio out' port so I got an adapter which allows the plugging in of the toslink cable into that port, which is basically like a headphone jack.. but still there is nothing happening with this setup.. no red light going through the cable from that port.
Does anyone know what I'm doing wrong? or what setting I have to use to make the TV send audio to the soundbar while streaming or using the usb ports? I already went into settings and under 'sound' I changed to from 'tv speakers' to 'audio out' and still nothing.
