Dr.Teeth posted:We just bought a new DVD player / receiver / surround sound package. Everything on it is hooked up right, I have checked it a number of times. But when we use it there is a low pitched hum coming from the speakers, notable the front L and R. Sometimes it quiet and hardly noticable but other times it can get quite loud and distracting. I am looking for suggestions on how to fix this. Sounds like a ground loop. Try plugging everything into the same power strip, and see if that fixes the problem. Another possibility might be electromagnetic interference. Do you have any other electronic equipment or fluorescent lights nearby?

ejstheman posted:Is it possible to get a 160W or so (real watts, not make-believe X-BASS MAXIMUM PEAK BURST INTO FLAMES) stereo amplifier, that I can connect to my computer, various video game systems, and two passable 80W 8-ohm speakers that I already have? Is it possible to get it for under $200? Look for refurbished and last year's model home theater receivers. I picked up an Onkyo TX-SR502 for $170 a while back, and while it's nothing special, it's got all the digital and analog inputs I need and it sounds decent. It's got 80 watts/channel. Why do you need 160W+, though, unless your speakers are inefficient as gently caress? The inverse square law says that you get diminishing returns pretty quickly, and it's entirely possible for me to literally shake floors with a mere 80W/channel, not even turned up to maximum.

You'll need a headphone-to-double-RCA cable, yours for not much pretty much anywhere. Something like this. I don't know what you're trying to accomplish with the cable you posted in the edit, but I don't see how that could accomplish much of anything. If your home theater doesn't have any digital inputs, you won't be able to do digital. If it's got six RCA jacks for 5.1 surround, you could do something with three of those headphone-to-RCA cables and the card's analog 5.1 output. Otherwise, you'll have to stick with stereo.

Strict 9 posted:Help! I can't seem to get 5.1 sound from my receiver through my HTPC. I have a new Onkyo HT-S590S Receiver, hooked up via a digital coaxial cable to my digital audio out on my Shuttle SN21G2. The Shuttle uses a Realtek ALC 655 AC '97 audio card for sound. Unfortunately, 5.1 sound over digital connections can be tricky. 2 channels is dead easy; it's just PCM, which requires no brains at all. 5.1 channels won't fit uncompressed, however, so both ends have to use AC3 (aka Dolby Digital - or, theoretically, any compression - but Dolby is of course the standard). Since licensing AC3 costs a decent chunk of change, and real-time encoding requires more hardware, most integrated sound chipsets don't offer it, and only have analog six-channel output. Fortunately, there's still hope. Most chipsets allow media to take over the connection completely - to preempt whatever else might be there with data streamed off the DVD or a file on the drive. In Media Player Classic, try opening a DVD or 5.1 audio file (if you've ripped your DVDs with AC3 intact). Then, go to Play->Filters->AC3 Audio Decoder, and select SPDIF for everything. Then, stop and restart the movie. If it works, your receiver should pick up on the signal and go into Dolby Digital mode, and you should get 5.1 audio. I don't know how to do the same for Mediaportal, but the functionality should hopefully be there to do the same.

pim01 posted:Every amp that's any good should be able to take plain copper - almost all speaker terminals I've ever seen were of the banana/screw type, where you could either use a banana plug or just screw the terminal tightly onto the plain wire. I don't think there's a special term for plain copper, but then again I'm not a native english speaker The banana plug/screw-down terminals are called "binding posts," and the ones with spring-loaded tabs are "spring terminals." Pretty much anything other than a headphone or specialty amp will use one of the two.
