[linux-dvb] I have the same experience with you.

    Yeah, I have Hauppauge WinTV HVR 950 at hand. And when I use it
under my Ubuntu, I got only the video too.
    When I dmesg, my ubuntu shows that audio stream was not handled correctly.
    I think this is because the driver.
    So you maybe wait for future driver to support this.
    Good luck.
