I have an HP 8740w with Nvidia Quadro FX 3800M video card. I connect SIIG displayport to HDMI adapter to the displayport. I connect a standard HDMI cable to the adapter with other end going to the T.V.
Video works fine but I can't hear audio out of the T.V. Speakers.
From what I've read, the video card needs to support audio via onboard sound on the VIDEO CARD or pass through from the SOUNDCARD (since it is coming out of the display port). When I look at the specs of my NVIDIA, it does not say anything about audio support whereas the 3800 (Desktop version of the vid card) does.
I am close to just accepting this is not possible (though in the back of my head I can't believe a $3000 laptop cannot do this and how HP could justify going from HDMI to displayport).
Here's where I'm at: running latest NVIDIA driver, running latest IDT drivers (for my sound) WIndows 7 64 bit, using SIIG Displayport to HDMI with AUdio ACtive Adapter (Says it supports: - Displayport 1.1 and HDMI spec - 2 channel stereo audio
Sony Bravia KDL46S-4100
I've tried: Put laptop to sleep Connected to T.V. Unsleep Check playback devices (no NVIDIA options is listed - though I can get the volume level for the "Digital Output Device (HDMI)" to flash with volume level.
CHeck NVIDIA control panel, notice that I have an audio settings page. From the I see: "Verify displays that will appear as audio devices in sound settings". My options are: - Display Port 1: empty dropdown box (when I click the down arrow, there are no options to choose) - Display Port 2: NO AUDIO CAPABLE DISPLAY AVAILABLE.
Note: I don't just want to connect to my headphone jack to get audio to my T.V. Help and thanks.
