Ahoj, koupil jsem vyse uvedenou grafickou kartu a pripojil ji kabelem HDMI k plazm. tv - obrazove vsechno ok, jen zvuk mi hraje pouze dvoukanalove - DD ani DTS jaksi nejde....audio HD driver mam nainstalovany - prehravam v KM Playeru...je chyba na me strane nebo tato karta nepodporuje vicekanalovy zvuk pres HDMI?
Dik za odpoved.

Karta by to podporovat měla.Takže bych hledal chybu v playeru.

Vícekanálový zvuk přes HDMI samozřejmě protlačit lze, problém je však v encodingu. To by měl řešit nástup Radeonů série HD 5000
Blu-ray (and HD-DVD) both support Dolby TrueHD and DTS-HD audio encoding, which offer discrete 8-channel audio output. The problem is that there's currently no way to send a TrueHD or DTS-HD encoded stream from a PC over HDMI to a receiver, the stream must be decoded on the PC. Cyberlink's PowerDVD will decode these high definition audio formats just as well as any receiver into 8-channel LPCM audio, but you need support for sending 8-channel LPCM over HDMI...
...All of AMD's Radeon HD graphics cards have shipped with their own audio codec, but the Radeon HD 4800 series of cards finally adds support for 8-channel LPCM output over HDMI. This is a huge deal for HTPC enthusiasts because now you can output 8-channel audio over HDMI in a motherboard agnostic solution. We still don't have support for bitstreaming TrueHD/DTS-HD Me still don't have support for bitstreaming TrueHD/DTS-HD MA and most likely won't anytime this year from a GPU alone, but there are some other solutions in the works for 2008...

To se ale týká jen specifické situace s osmi kanály, ne? 5.1 by snad normálně mělo fungovat.
