HDMI questions

Two questions:

1) I've seen DVI->HDMI converters, but is there anything to get audio into the signal as well? I have the standard 1/8" line out and optical out.

2) Is it a bad idea to run a ~30ft HDMI cable (purchased from Monoprice)? If I can't find a DVI+audio->HDMI, would running an audio cable of this length result in bad quality?

    1) I don't think so

    2) 30ft+ isn't going to be bad. Hiding it will be the hardest part of it.

    1) Yes, but you're looking at paying $200 or so for a DVI+Digital audio to HDMI convertor. Skip it.

    2) As long as the cables are decent quality (and they should be, coming from Monoprice) you won't have any issues with a 30' run. You'll want to worry when you get closer to the 50' mark.

    1) Nothing cheap, no. I imagine something out there exists, but it will be more expensive than simply upgrading your vid card to something with an integrated HDMI A/V out. 'Cause that's, like, $50. Maybe less.

    EDIT: *disregard half of the below, because apparently my monitor rendered the bolded above invisible*

    2) 30' should be fine for HDMI. I'll probably disagree with Peregrine, though, in that whether I'd want to do a 30' analog audio run probably depends on what kind of source we're talking about here. If it's from an on-board audio out, I'd think long and hard about some kind of upgrade allowing for either HDMI A/V, or (if you already like your video card) RCA SPDIF out. TOSLINK (optical) can go 30' as well, but running that might be a pain in the ass and somewhat expensive. Whereas carrying digital over RCA results in the exact same quality, for less. You can probably get a sound card with an SPDIF out for like...$20 or so? Hell, some motherboards actually have an SPDIF header on the board that simply hasn't been run to a port on the case...something to look into.

    EDIT: Fuck, I guess a 35' TOSLINK cable only runs like $9-$10 on monoprice. Cheap. Still, IIRC you have some other considerations with TOSLINK that you don't have to worry about with RCA coax, like maximum angle for bends and shit.

    For point #2, I assumed he was going to run digital audio over the 30' length. The bend contraints aren't nearly as bad as you think - it's just a matter of giving it a gentle curve and not staplegunning it to the corner. :P

    Oh, I apparently just failed at reading. Didn't see that he had optical out. Don't ask me how.

    Yeah, just run optical. Length will not affect quality at all. If you run that 1/8" analog instead (presumably using a 1/8"->RCA adapter) it will sound, at best, utterly mediocre.

    According to Newegg, I have S/PDIF optical and coax out. Would coax be better than optical? I'm not really sure what the exact setup is going to be since I'll be moving in June, but I'm just trying to get an idea of what I'll need.

    Thanks for all the help, I'm pretty clueless when it comes to this kind of stuff.

    Coax will let you use the typical RCA red/white/yellow cables for the connection, if you happen to have a 30' length of it, and doesn't have the limitations of "don't bend the cable." They're both a digital connection though - and since you're not actually going to need this until June you might as well get a better look at the layout before making a decision. :P

    Coax S/PDIF versus optical S/PDIF will provide the same quality; it's the same bistream carried either way. The only concerns there are physical, like "will I get a signal or won't I" and cost (TOSLINK cables run marginally more).

    So assuming your receiver has both inputs, the choice is largely up to you. I prefer RCA in most cases, especially for long runs, because it's just a bit easier. And if you're a cheapass like me and you already have some cables laying around, you can do things like use an inline Female->Female adapter to splice two together.

    Of course, my receiver (like most, in my experience) has a lot more TOSLINK inputs than RCA...I think I have like four optical ins to just one coax input.

    EDIT: Not that optical->coax adapters are insanely expensive or anything ($10 maybe?)...hell, I've actually built one for a project at school. But usually it's jut easier to choose whichever is more convenient and requires less equipment.
