No sound using MediaPortal v.1.2.3 (1 Viewer)

[Zoltan Nagy]

My HTPC consists of:
ASUS P7H55-M PRO,
4GB RAM
Samsung TV
YAMAHA RX-V440 for audio.
OS: Win 7
MediaPortal (MP): version 1.2.3
For playback audio the S/PDIF port is connected to my ampliefier with optical cable.
Foobar2000 playback of Audio files/disc works. Settings: audio output redirected to S/PDIF. Out Realtek Digital Output (Optical íhigh Definittion Audio)
PowerDVD, MPC-HT, VLC Player, OpenSubtitlePlayer: playback of DVD/BluRay disc or mkv file ok. (Audio: output: S/PDIF, Audio renderer: Realtek Digital Output Optical)

Problem: Media Player
No sound when watch TV channels.
When I play back DVD disc within MP (Play disc): No sound.
Playback the recorded channels/file. No sound
Exception:
When play disc within MP: audio playback: Ok, sound is Ok.

The hw is properly connected and settings in other media players are ok because:
If I playback the MP recorded file/channels with VLC player or MPC-HC, it also play sounds, too.

Current settings in MediaPortal Configuration:
Codecs and renderer:

MPEG2-Video decoder: Cyberlink Video/SP Decoder (PVDV9 UPnP)
H-264 video decoder: Cyberlink Video Decoder (PVDV9)
MPEG/AC3 audio decoder: CyberLink Audio Decoder (PVDV9 UPnP)

DVD Disc/Images Codecs
DVD video decoder: Cyberlink Video/SP Decoder (PVDV9 UPnP)
DVD Audio decoder: Cyberlink Audio Decoder (PVDV9 UPnP)

How to make setting to:

Thank you for any help in advance.

Hello!
Could it be that MP is muted?

To check this:
Open MePo in window mode -> Play a music file, a movie or LiveTV -> Open volume mixer in windows taskbar

See:

Hi,
The MePo was muted then I un-muted.

Please find screen-shot attached.
If I play audio disc the volume indicator is in green and sound is OK.
Still no sound, any other idea?

Zoltan Nagy:
Sorry for long time no response! You could try to use -> Audio Renderer: Default DirectSound Device.
Else you could try to use a different audio decoder.
Thanks!

Thanks, the setting::>
Audio Renderer: Default DirectSound Device
it works now. There is sound.
Why I wanted to render/direct to DirectSond Realtek Digital Otput (High Def Audio)?
Because I want not to encode by the plug-in of MediaPortal but the Amplifier itself.
I want to play back DTS audio disc, as well. At the moment only sizzling can be heard. I want to send digital signal via cable and let it encode by the amplifier.

Ps. I also have other problems/questions and go for checks or write new threads.

This is possible with Default DirectSound as Audio Renderer too. It is just a Audio Codec setting -> Just tick passthrough for DTS/AC3 in the audio decoder settings.

You are not alone with this problem. I think there are some threads about it here.
