Sorry to hear that you are having the problems with audio. If you have not already tried to do so, I suggest attaching the system to a different TV and see if there is a difference. I also suggest swapping out the HDMI cable just to make sure it isn't a defective cable.
Jimco has a great audio FAQ at the start of the forums and he does go into details for troubleshooting HDMI issues. There are some great suggestions here.
I have external display - Samsung T240. Few days ago I got my new audio system - ONKYO HTX-22HDX. My current setup is:
Vostro--(hdmi)------>Onkyo--(hdmi)----->Samsung
This is working fine. My laptop sends both audio and video over hdmi, audio signal is processed by Onkyo, video is sent to external display.
Samsung T240 has also SPDIF audio output. What I'm currently trying to achieve is this:
Vostro--(hdmi)------>Samsung--(spdif)----->Onkyo
This setup would be more convenient for me. This way I don't need to have Onkyo powered on all the time, if I want only video. The problem is that Windows thinks that my display doesn't support audio. I believe this is not Dell issue. Problem is somewhere in nvidia and/or display, because if I capture EDID of display with MonInfo, there is no external EDID block (which is there in first setup). External block contains information about audio support and other stuff. I'm trying to combine EDID information from Samsung and Onkyo, to force audio output, but so far I had no luck.
Anyway, I was thinking, if it is possible to use HDMI with Intel GPU (I dont' need nvidia). Maybe it could solve my problem. Another advantage is, that intel can bitstream DTS-HD (over hdmi tough), nvidia 310m supports only DTS core.
According to this
it is possible to enable or disable the hybrid graphics function, but I have no such option in BIOS (A10). Is there any way how to disable nvidia, or at least get HDMI with Intel working?
Sorry for the delay in getting back to you. I have looked into this and my the information that I have found does mention the ability to disable hybrid grapics. Since you don't have that ability the only thing i can think of is to go into device manager and disable to nvidia drivers and see if the system runs with the integrated drivers. I am not really suggesting this as a fix only as an experiment to see if the problem is really with the notebook and not with the SPDIF connection between the Samsun and the Onkyo.
Thanks for reply. When I disable Nvidia driver in device manager, laptop works fine with Intel GPU. But if I connect external display, Nvidia driver is automatically reenabled. If I uninstall Nvidia driver, laptop uses the intel one, but whenever I connect HDMI, I get black screen.
I am looking to get an Vostro to see if I can find out if there is a way to turn off the Nvidia GPU. I should have more info later today or early tomorrow.
