Thanks, I will try that.

So, the interference problem has been taken to a new level.

I now have the pc connected to the tv via hdmi.

(For those who haven't read the entire topic, I was getting interference though the speakers that would be affected by motion on the screen. The interference would get better or worse depending on what was on the screen).

Now that I have them connected to the TV, I have the very same issue.

So I thought it must be a problem with the speakers, no, when I connected them to a cellphone and ipod, there was no interference at all!

Can anyone explain this?

Additional info. Now that the speakers are at the TV, I used a 3.5mm male to male jack extension and connected it back to the computer and I had almost zero interference.

"Whatever is available". Used market availability fluctuates day to day in unpredictable ways.

Well let me know when that happens.

Sounds like hardware acceleration isn't working then. That would explain it. Either a driver or flash plugin issue.

I thought I already did. Either a software issue or more likely EMI between the video and audio circuits in your computer.

What exactly did you change? I thought that's how it was setup before.

This thread is so confusing to read. You keep changing so much so often that I can't even tell what your setup looks like anymore or what you're trying to do to it.

Yeah I like to move things around a lot.

I'll go through it step by step.

1. Build the HTPC (the same pc discussed in this topic). Plug in 2.1 speakers which are on the same desk of the PC. Everything worked fine, no interference.

2. Decide to move the HTPC into the living room. Exactly the same setup as before, just moved to a different location and then I had interference that seemed to be affected by what was showing on the monitor. Unplugged the monitor and that didn't make a difference.

3. Tv came, so I moved the 2.1 speakers over to the TV, plugged them into the TV's headphone jack and connected the PC to the TV via HDMI. Speakers had a constant loud hum which again seemed to be affected by what was on the TV (later realized whites would make it worse, darks would make it better).

4. I then unplugged the speakers from the TV's headphone jack and used a extension cable to reach across the room to plug it into the PC (speakers are still located at the TV) and now there's no interference.

Obviously the problems are due to cheap speakers which I'll ultimately upgrade. But ideally for now I'd like to be able to plug the speakers into the TV so the over the air channels, the PC via HDMI and PS3 could all use them.

I see that the interference when they were at and plugged into the PC was a proximity issue. This doesn't appear to be the same when they are at and plugged into the TV because I even went as far as to remove the speakers from the TV, set them up in the middle of the living room floor and plug them into the TV and I still had exactly the same level of distortion.

On the topic of soundcards, some of them have optical in, does that mean I could take the digital sound output from something like a tv or ps3, use the soundcards dac and then send it back to a receiver / amplifier?

It should do.

Actually the above tests and results seem to prove the exact opposite. The issue is with the computer, not the speakers. As stated by me earlier, repeatedly.

It should work (I can't be sure because nobody does this so I don't have any real info. to go on) as long as:
1. You make sure the PS3 is outputting stereo LPCM, no compressed audio streams
2. The PC is on
3. The audio card is manually set to spdif passthrough mode

Again though I can't promise that it will work. It should in theory.

I'm surprised no one does it, wouldn't it greatly increase the sound quality?

If you're just doing passthrough? No. Unless I'm misinterpreting your suggestion. It also greatly complicates the setup and doesn't work with all audio formats.

Well I was just going from what I've learned here (and random assumptions I'm making) so here's my understanding.

Audio quality is all about the digital to analogue conversion. Fiber optic output a device is digital. So you send the digital signal to the soundcard so it uses it's DAC and then sends the analogue signal out? Meaning you would be using the pc's soundcard rather than the devices? (More of a hypothetical question as opposed to something I'd actually do).

Well they work fine on the PC now, but don't on the TV so I'm not sure how you got to that conclusion. I re-read what I typed just to make sure I didn't slip up on anything. The only thing I can add to clear a possible misunderstanding is that when I had the speakers at the TV and plugged into the TV the loud hum was an issue when viewing the PC, over the air channels and the ps3.

I appear to be having framerate issues still. I know I said before it was only a youtube problem, but watching hulu today was as worse as it's ever been. Is there any graphics benchmark thing I can run to decipher if it's a software issue or an issue with the GPU/drivers?
