For some reason I can't figure out, I can't get any sound on the DVD-Audio stream of "Gaucho." On the other hand, when I play the disc in a non-DVD-Audio DVD player, the regular Dolby Digital track works fine. When in the DVD-Audio player, the video menus work, and the track appears to be playing on the readout on the player. It just produces no sounds. I put in other DVD-Audio discs into the DVD-Audio player and they play fine, so I know my settings are fine. I'm getting an exchange, but I'm wondering if anyone has had such a problem and, if so, what is the solution? Thanks.
