i tryed it yesterday with my ati hd mobile and my b series tv but not working till now.
any news to this topic?
is there a solution for this till now?
i mean solving this via software not hardware.
1. PS3 (5.1 only, DTS does not get passed)
3. Motorola QIP 6416 FiOS (requires passthrough be selected in device set-up menu)
T-FXPAKUC 1206.3 + SamyGO
I have an F6300 series, and examining the E-EDID information it advertises that it only supports PCM 2.0 16/20/24b depth at 48kHz and that it only has front right/left speakers (which is, in all fairness, the truth...). So, any device using autodiscovery, which is nearly all of them, will only send it PCM 2.0 in the first place.
However, if you can override a device's discovery mechanism and force it to output DTS or AC3, the tv will pass that along. Basically, it does zero audio decoding, just passes it straight along. This means you get static unless your receiver is decoding, of course. Note that this is only DTS over an optical, not DTS-HD, because you can't run DTS-HD over optical due to cable bandwidth limitations -- just AC3 5.1, DTS 5.1, or PCM 2.0.
I was able to construct an E-EDID block that claimed to support a 5.1 speaker setup with AC3 and DTS support and convince my windows installations (three different computers) to use this fake E-EDID instead of the one it got from the monitor, and I was successfully able to pass AC3 from the computer --hdmi-> TV --optical-> receiver, and output 5.1 sound. If I were able to flash this E-EDID to the tv itself, I wouldn't even have to override the connected devices' autoconfiguration...but it would hardcode the TV to support only whatever I put in the E-EDID. The *proper* way to do this would be for Samsung to discover the capabilities on the attached receiver, and advertise *that*...but that requires dynamically updating the TV E-EDID when new receivers are connected to the ARC channel, and I don't think that'll happen anytime soon. The autodiscovery wouldn't work for optical out, of course, though a menu allowing us to configure the optical capabilities would be grand.
For those curious how to override their E-EDID information on Windows XP and higher, check out EnTech's "MonInfo" which can extract E-EDID information from the TV and can create override driver files from binary E-EDID blocks, and Deltacast's "E-EDID Editor" which allows you to edit those extracted binary E-EDID blocks, which you can then open in MonInfo and use to create override driver files. No, I won't post my E-EDID file, because it's unit-specific (not just model) -- extract your own E-EDID and modify it.
Note that most computers don't actually encode to AC3 or DTS for sound output (though they'll pass it along if that's the source encoding), just PCM, so unless you have a dolby digital live encoder in your sound output stack you still won't be able to get 5.1 through the optical. It should work thoguh ARC, though, even just using PCM. N.B. -- I haven't tested audio return through ARC, just optical, so this last is just conjecture.
