I have connected my receiver with HDMI. I only have sound with Directsound and not with WASAPI when I set the audio output in XBMC to HDMI.
But I have sound with Directsound and WASAPI when I change the ouput from HDMI to Optical/coax. But I haven't connected my receiver optical and I can't select DTS-HD.
Why I have no sound with WASAPI when I set HDMI as output?

Have you checked what Supported Formats says in Windows?

I followed all steps, but I don't get sound with WASAPI. In windows sound manager I have the same 2 outputs. There is one output to my tv that don't work and one output to my tv that works, but not with WASAPI. In AMD Vision engine control center I can't select my tv as standard device, but only spdif. So I think this is an driver issue. Anybody suggestions?

How is your HTPC connected to HDTV? Is there an AVR in between HTPC and HDTV?

Although your TV supports Dolby Digital it's more than likely that is only from terrestrial or satellite broadcasts from whatever tuners it has, very few TV's will allow Dolby Digital from an external source connected to the HDMI to be passed through to the SPDIF out, that's probably why you had no sound initially.
Unfortunately there is no simply solution for what you want to do as SPDIF to AVR and HDMI to TV will require different settings for sound if you want the choice of DD5.1, therefore your choices are:
1. Route sound direct to AVR via SPDIF and always use AVR for DD5.1 sound (Select SPDIF 5.1 in XBMC)
2. Route sound via HDMI to TV and then via SPDIF to AVR but then you'll always be limited to stereo 2.0 sound (Select Analog 2.0 in XBMC)
3. Change XBMC settings manually so you either route sound direct to AVR via SPDIF, or via HDMI to TV and then via SPDIF to AVR (Switch between SPDIF 5.1 & Analog 2.0)
4. Use Profiles to configure a TV Profile and a AVR Profile so you can switch between settings as in 3. but without having to do it manually each time (Switch between SPDIF 5.1 & Analog 2.0)

Thanks for your reply, but I have already get sound with WASAPI dolby digital to my tv. I don't know why it works now without change any setting.
The only issue now is that he don't play GUI sounds. I browse now silently through the menus. Does anybody know why sound output during music and videos work, but no GUI sounds?

Perhaps a daft question, but have you got GUI sounds enabled? double check to make sure in the course of adjusting things you haven't disabled them.

Towards the bottom there are two settings:
Audio output device
Passthrough output device
Do you have both set to HDMI?

The "Audio output device" is for LPCM audio whether from music files or audio that is decoded from a passthrough format such as DTS (only if the relevent "capable receiver" option is not selected), so it's sounds like WASAPI has a problem with certain types of LPCM.
So yes it's fine having that sent to Directsound unless you're an music audiophile after bit for bit reporduction, movies with DTS or whatever will use the Passthrough device.
