Hello.

Lets keep it simple:

I have a computer in a bedroom and Edifier S530D speakers next to it, but I also have stereos next to my TV on livingroom which are these http://www.thomann.de/fi/m_audio_bx8_d2.htm, so my audio systems are not that cheap.

The current setup goes like this:

Computer/3.5mm - 3.5mm/5m long cable -> 3.5mm switcher box.
3.5mm switcher box -> TV/3.5mm - 3.5mm/1.5m long cable.
3.5mm switcher box -> Stereos/3.5mm - 2x 1/4" TRS jack/5m long.

The deal is that I want to use my computer speakers too when I am playing for an example and there's only one 3.5mm connector behind my computer, which mean I need a some kind of 3.5mm splitter or splitter cable. Does it reduce sound quality with this setup? Can I keep both stereo sets ON at the same time and decide in my computer settings which speakers I want to use or do I need to turn them off and decide which I wanna use?

Here is a simple picture: http://tinypic.com/r/2w4wf9k/8

(I do also have headset but I am using them only in my frontal 3.5mm connector and unplug them back in the closet when I am not using them. We have two cats and one of them likes to eat thin cables whenever it is hungry, so I need to "hide" my cables)

Besides the setup above, I have 3x HDMI going from TV to PS3, PC, Digibox, but that's different deal now and no need to worry about them.






 
Hi Marko Laukkanen
That depends , in some cases it can , i have done this without issue , but have heard of cases where
it does reduce sound quality
I guess for the sake of a few dollars you can try for yourself with something like this

Hi
A decent quality short Y cable will not audibly reduce the sound quality.
In that setup the computer speakers will be on all the time as well as the stereo or television.
You cannot select in your computer settings which speakers will be on as it is a single output,you will need to turn your computer speakers on or off as needed by the power button or volume on the speakers.

Hey, thanks for the answers. I looked few local shop on the way home but prices were too expensive. So I tried to find a store with decent quality and price included with reasonable low postage bill and ended up to order thishttp://www.kauppasatama.fi/tuotekuvat/big/mm-10a.jpg The cable is Multimedia Y-cable by deltaco and cost 3.90€.


Is it good enough to do the job? There was cheaper and more expensive cables available but I wanted to shoot a try on this.
