I have been fighting video stutter on Vista MC for months. I was using a DMM Radeon HD 3870 card over HDMI. I have a second system with a VisionTek HD 3870 card. It has the same stutting issues using MoBo sound out. My everyday PC was recently upgraded and I chose a VisionTek HD 3450 card. No stutter.


So I did a video card swap and it solves the stuttering problem on the living room system. But I can't get sound over HDMI. Same TV and same HDMI cable.


I'm using Catalyst 8.6. I installed the RealTek ATI HDMI device driver after catalyst. No help. This is supposed to work.


Device manager says everything is working but the sound control panel says that HDMI is unplugged. I'm getting 1080p video so I doubt it.


I'm wondering if you need an SPDIF cable to the Mobo or something.


The documentation sucks for these cards. Nothing printed except a quick start guide. Manual on CD is for 2000-series cards.


Has anybody got this to work producing sound over HDMI? MoBo sound output works fine when selected.


Thanks for any help in advance.

It have the VisionTek HD3450 in a dell XPS 410 (just ordered my parts for my HTPC). I just plugged it into the mobo, installed the drivers from the cd that came iwth the card and sound and video worked?


I did have to go into the control panel and set the 3450 as my default audio device.


Also, I had to to uninstall the driver for my x1950 pro prior, so maybe you should uninstall any old drivers that could be getting in the way, then reinstall?


Thats all I can do for ya, sorry

Thanks, That at least confirms no internal cable is needed.
