Hi,

This is all new for me, but I am desperate for help and seeking the expertise of those on this forum. I have been trying to build a home theater system with a pc and ps3 connected to an HDTV. It will primarily be used for gaming. I have ordered all of the parts except for the speaker system. I am looking for a 7.1 speaker system that can be used for my tv, pc, and ps3 at the same time. I find the audio-side of things to be very confusing. From what I understand, uncompressed pcm is what to shoot for. I want a system that can handle this. I know a lot of the systems I looked at before only had hdmi pass-thru when it comes to audio.

I didn't know whether it would be best to use the sound from my ati 4870 graphics card or the onboard 7.1 audio. I figured I could connect from the 4870 using hdmi and still get 7.1 sound.

I have ordered a Philips 47PFL7403D/27.

I have the following computer:

CPU: Intel® Core2 i7-920 2.66 GHz 8M L3 Cache LGA1366
COOLING FAN : Asetek Liquid CPU Cooling System (Extreme Cooling Performance + Extreme Silent at 20dBA)
MOTHERBOARD: MSI X58 Platinum Intel X58 Chipset SLI/CrossFireX Mainboard Triple-Channel DDR3/1600 SATA RAID w/ eSATA, Dual GbLAN, USB2.0, IEEE1394a, &7.1Audio
MEMORY: 3GB (3x1GB) PC1333 DDR3 PC3 10666 Triple Channel Memory
VIDEO CARD: ATI Radeon HD 4870 PCI-E 16X 512MB DDR5 Video Card
HARD DRIVE: Single Hard Drive (1TB (1TBx1) SATA-II 3.0Gb/s 32MB Cache 7200RPM HDD)
Optical Drive: LG 20X DVD±R/±RW + CD-R/RW DRIVE DUAL LAYER
Optical Drive 2: 16X DVD ROM (BLACK COLOR)
SOUND: HIGH DEFINITION ON-BOARD 7.1 AUDIO
OS: Microsoft® Windows Vista Home Premium (64-bit Edition)



I am trying to get a system before Christmas. My overall price range is $300-$550. Thanks in advance for all the help. It will be truly appreciated.

do you have a receiver? You said you are missing your speaker system, so i'm not clear if that means missing speakers or missing speakers and receiver. i think you're looking at $4-500 just for a receiver that will do the uncompressed audio through HDMI, so that's pretty much your hole budget.

I know there are some HTiB setups with 3 HDMI inputs now, but I have no clue which would be best.

Here is one:

I don't have a receiver yet. I'm looking to buy a system with a receiver, 7 speakers, and a sub woofer. From what I understand the system that you are recommending doesn't decode the audio. It has Pass through, which means that video and audio are passed through the HDMI like its a switch, the audio is not processed by the receiver and is sent through the HDMI to the HDMI source.

hdmi reciever pioneer elite vsx 92
sapphire st1&2's 7.1 speaker package
svs pb12 +/2 sub
ps3 hooked up hdmi to reciever and to plasma (no burn in problems)
dell xps 630 gaming computer 9800 gt sli streaming to ps3
creative X-FI gaming card


The question is does the newer hi-bit 7.1 surround codec stream to the ps3?

At least I know it must be lpcm and not bit stream.

your reciever must be hdmi because the ps3 doesnt support multi-channel analog inputs (which are the 8 separate cables) that lots of older recievers have.
Use your reciever to handle all your audio because it will have more power
Me personally have all my audio streamed wirelessly to my ps3 from my computer and can access all my music,video,and pictures and display/listen to them
The only downside to not having my computer next to mt HT is the X-FI sound card is not connected directly to my system
