Re: hdmi no sound

Check TV Speaker setting in menu, check audio input setting as well as some TVs can be set to use digital input or only feed out digital output on some inputs.
Also try to verify digital output if present.

All HDMI cables are able to carry sound. Sound is carried over the video pairs on the cable in the vertical blanking interval.

Well, I have a cable that will not carry any, no matter what I do. Got a better quality one and it works fine as kind. Cable is / was between my server and a 40" Samsung TV.

DVI to HDMI cable? That's a different affair.

HDMI cable. A DVI cable doesn't carry any sound.

Re: hdmi no sound

Firmware update might be worth a go if the set allows you to do so ?

There is no reason a DVI to HDMI cable cannot carry sound as before I said that it is carried on the video pairs in the blanking interval between frames. It is up to the graphics card or other peripheral as to whether it implements HDMI audio over DVI, as it is technically a non-standard feature. Technically you could even have a DVI to DVI cable where both graphics card and monitor were capable of sound, but they would be using HDMI, effectively, over a DVI cable. I'm not aware of any monitors that do this, though.

There should have been no reason your previous HDMI cable did not carry sound. It would be literally impossible for a cable to fail in such a way where it transmitted video, but was unable to transmit audio, unless it had some kind of audio-stripper chip in it! (but who would make such a cable?) There's a small chance the EDID (configuration) lines were damaged in the cable - in which case it would probably fall back to some kind of default configuration, low resolution 480p for instance, which for some reason the TV might not support fully.
