I am using HDMI from the BD player to an HDMI switch that connects my devices to the HDMI input on the Vizio sound bar. It provides limited audio options on the BD player. The disc is providing Dolby TrueHD, but my sound bar supports Dolby 5.1 and DTS, not Dolby True HD or DTS MA. So, I believe it is converting the audio to PCM. This is causing the problem with the audio drop outs. I can even replicate the drop outs on my PS3. On the PS3, however, I chose not to output PCM 48 MHz audio and the drop outs do not occur. On the BD player, I switched to the SPDIF cable and that gives me several audio options for Dolby and DTS, and I get great audio and the drop outs are gone. So, in actuality, I suppose it is the sound bar that is the issue.
