No sound from LCD TV when connected to Dell PC via HDMI cable
I have a Dell Studio Slim 540S desktop PC with Blu-Ray player and integrated Realtek HD Audio sound. When I connect this to my Panasonic Viera TX-26LXD70 LCD monitor via HDMI cable I get picture but no sound. However, I have had sound previously and therefore I suspect that it might be settings issue on the computer. The Realtek driver is up to date. Furthermore, the monitor is set as the default device for sound production. When audo is present (e.g. music file through Mediaplayer) and properties are checked the monitor sound output is shown to be working.
Alongside my PC is and XBOX 360 system that is also connected to the above mentioned LCD screen via HDMI cable. In this instance, I get both picture and sound. I have tried swapping the cables between PC and XBOX but this has had no effect.

You need to match the connectors, very likely your TV has HDMI or DVI, so use the external video port in the computer, DVI or HDMI, you can buy a cable with a match to the video connector you have in both devices.
This has to do with your video driver on your laptop that needs updating.
go to Control Panel\All Control Panel Items\Windows Update
download any updates from here.shutdown laptop, check the cable connection from laptop to tv then restart.
If still no luck try another hdmi cable
Not sure what you mean by "optical connection" but you need to connect your SkyHD box to your TV using both HDMI and SCART cables. Your Sky HD box will then send the signal via the HDMI cable for the HD channels and the SCART cable for the SD channels.
If you would like to use high definition audio decoding, connect the HDMI from the blu ray player to the receiver. If that it not an option for you due to lack of equipment such as an additional HDMI cable to go from the receiver to the television for the video portion of the signal, then connect your optical cable again. After the optical cable is connected, make sure the Dolby Digital decoding is enabled on the receiver, and that the media you are playing also has a version of 5.1 surround sound. Then, enter the setup menu of the player (which I suspect this is actually where the problem might reside in your case) and make sure that Dolby Digital and DTS are not set to "downmix." Dolby Digital should be set to output Dolby Digital and so on and so forth...hope this helped.
Do you have a High Definition cable/satellite reciever or a Blu-Ray player? Does your tv have a HDMI input or component or DVi or all of those? Most newer HD components use the HDMI connection. The HDMI connection is a single cable that has both video and digital audio together. The component connection is a connector with three rca jacks that are red, green, and blue. Audio is connected seperately with this connection via red and green rca audio jacks or a digital audio connector. The last is a DVi connector that is found on computers. Some older HD tvs and components use this connection. There are adapters available to turn a DVi connection into a HDMI connection. So if your TV does not have a HDMI connection but your HD reciever does you can use and adapter but you will not have any audio this way without using a seperate connector for the audio.
You say this doesn't happen on regular cable or when playing a regular DVD. Hmm. Is this Blu-Ray player connected by simplink? HDMI is a bi-directional format cable, so there are cases in setups where your tv can send commands to your blu-ray player and vice versa. It could be a problem with your blu-ray player that it is sending for some odd reason a mute command to your tv. Or is processing a command that your TV interprets to be a mute command when playing blu-rays. Because if it was the TV itself chances are you'd see this when watching a normal DVD or on cable as well. Since you say you're not, it leads me to believe the issue lies with the blu-ray player itself.
The best possible solution to your problem is :
Connect your blu ray player directly to the HDMI input of you Plasma and watch HD video....
and connect the 5.1/7.1 sound thru the optical or the coaxial link directly to your AVR 3805.
You will not loose anything on the Blu-Ray.
The sound is best processsed by the AVR3805, while the video, which is the real upgrade (BluRay) in terms of resolution of picture would be processed by your plasma.
