HDMI sound very silent (1 Viewer)

[max91]

Hello,

I'm running MP 1.8 on a Fujitsu Siemens Scaleo EVI. OS is Win7.
The HTPC is connected direcly to my TV via HDMI.

When watching TV in MP, the sound is very silent. Listen to music or radio works fine.
The volume option is set to master. On wave the volume is loud enought, but I can't change the volume.
The MPEG Audio codec is set to ffdshow and the output codec is Realtek HDMI.

Has anyone an idea how to solve that problem?

Check the 'Audio Renderer' settings are correct for TV ('Default DirectSound' is usually the safe/most likely to work option) - see http://wiki.team-mediaportal.com/1_MEDIAPORTAL_1/141_Configuration/Settings/3_TV_Settings
