Sound disappeared after connecting HDMI

[tommitn]

Hi,

 

I recently bought a TV alongside with my PC (Win7) + DVBViewer. After I connected the PC's video card with HDMI cable to the TV, I'm not able to get sound from DVBViewer to the stereo system which is connected to PC's SPDIF connector. Windows sounds work ok, VLC plays the sound via SPDIF, but no matter how I search, I can't find a setting in DVBViewer's options to set this straight. I removed the HDMI cable and booted the computer - doesn't help, I've checked the Windows sound playback options which obviously are ok, otherwise I wouldn't be hearing the Windows sounds or VLC sounds in my stereo system. Any ideas how to fix this?

 

Another problem related to HDMI connection with the TV: I get the sound from the computer (DVBViewer), but the DVBViewer window remains black. I get the pc screen in the TV when I boot the computer, but once I'm in Windows, I only get the Windows desktop. I can drag a window from the monitor screen to the TV screen but it remains just a dark square. Does somebody know what might be causing this and most of all, how to fix it? :-)

 

Thanks in advance,

The HDMI is probably your default audio renderer. To use the optical output, you will need to select that in Options-DirectX-Audio. Available devices are in a drop-down list. The optical one may be described as "Digital audio output".

Audio renderer

On my system, I have the optical output set as "Audio B" renderer, leaving HDMI as Audio A, so it can be switched easily on command.

 

You have a dual-display system (PC monitor + TV) set up for "extended desktop". You might find it simpler to have the TV cloned from the main display. The black window may simply be a codec issue, but you need to post your support file (see link at top of page) for specific help.

Thanks for your help. The renderer that worked was the Default WaveOut Device. I also set up a keyboard command to change between Audio A and Audio B.

 

I include in this message the support.zip as you suggested. I write down here the other information that was required in the instructions: Motherboard Asus P5Q-PRO, rev. 1.xx, CPU Intel Core 2 Duo E7400@2,80 GHz. TV-card is Digital Devices Base Device, driver 2.3.0.47. Video card is ATI Radeon HD 4350, driver 8.850.0.0

How can I clone the DVBViewer screen from my computer to the TV? I have a Samsung that allows me to watch the recorded programs over wifi connection, but it doesn't support fast forward or rewind, just play, pause and stop. And subtitles are not passed (in Finland we have some channels, which use the DVB standard subtitles). In many ways DVBViewer is superior and I would like to continue using it with the TV-set.

You have selected a CyberLink video decoder as default. On Windows 7, I find the native Microsoft decoder, with EVR, works as well as any, except for AC3 audio. You could try that next to see if it brings back the picture.

 

To change the mode for the dual-monitor set-up, you would need to enter the "Catalyst Control Center" and change display mode to "duplicate".

There are some downsides to this. You might not be able to control resolution independently for each monitor. The taskbar will appear on the TV, and may even appear in full-screen mode (though there is a work-around or this). It all depends on whether you want to keep both displays connected. You might find a solution to your original problem in CCC, by changing some of the settings.

 

You don't seem to have Recording Service installed, so you must be using another DLNA server to stream video to the Samsung TV. Each server has its own capabilities, though sometimes the profile for a specific client can be modified. With the DVBViewer Recording Service as DLNA server, my own Samsung B-series TV can play back recordings with "Jump" feature enabled, though still no subtitles, sadly. RS can stream live TV, too, plus it has a better web interface for TV Guide and remote Recording control. It's a bit difficult to set up first time, but there's a guide on the Wiki.

 

Streaming seems to produce a better picture than HDMI. This could be because the TV can use its own picture processing on the stream, which may follow the same path as the output from the internal tuner.

Thanks again! I decided to install Recording Service. I did it some time ago, but then the troubleshooting has been a bit slow. I manage to record programs with RS and of course watch them on my computer using DVBViewer. But the streaming doesn't seem to work. I've studied the firewall settings and firewall log and to me it seems that things are ok there. RS debug log indicates, if I understand correctly, that RS and my Samsung TV get connected. And Samsung actually shows DVBViewer in the list of sources for videos. But...then the TV says: No video files found on the connected device. And the same with pictures: No photos found on the connected device.

 

What might be going wrong here? It seems I'm so close, yet hours go by and I don't manage to stream the videos to the TV. Alle my media folders are shared and I've made sure that media streaming to my TV is allowed in Control Panel's advanced sharing settings. Now I'm going over the same things over and over again :-(
