Hello, I have a WDTV Live Streaming. I have it connected wirelessly. I have MKVs with 48kHz AC3 audio tracks that the unit does not play properly; the video works properly but the audio is nearly silent (static picks up during playback). The AV unit is a Sony STR-DE835, with optical inputs that support DTS and AC3. The WDTV unit is set to work with a AV unit that accepts AC3 and DTS in the Audio/Video Output settings.
During playback of the affected files, the AV unit displays the correct information about the audio track, a blue light indicates that it is receiving an optical input, but no sound is forthcoming.
The optical cable has been swapped and verified with another device (PS3).
If I set the WDTV to Stereo instead of Digital Passthrough Via Optical Only in Audio/Video Output settings, the sound works albeit in stereo. If I play a file with a DTS track, the unit works as intended.
