They're fairly easy to build but you can also buy one. Depending on how much time/money you want to put into it, the fidelity of the output can be affected. The simplest form of passive mixer will slightly degrade the sound quality from both the TV and the PC, although some people can't tell the difference.<br /> <br /> It's possible your IR transmitter has a built-in mixer if it has two input jacks.<br /> <br /> Another alternative is to set your TV sound output to mono, and feed the TV audio into one of the IR transmitter's channel inputs (e.g. the left) and the PC left <b>or</b> right audio into the other channel input. (this assumes the PC 'warning' sound is played on all L/R outputs, and also assumes the IR transmitter has a stereo input) The downside of this arrangement is obvious...no stereo TV and you hear it only in one ear...which can be annoying to some people.<br /> <br /> Note: you most likely won't be able to use 2 separate IR transmitters (one from the TV and one from the computer)...they'll just interfere with each other even when there's no sound.<br /> <br /> An alternative is to just have the volume of the PC speakers set high enough that you'll hear them even with the headphones on.<br /> <br /> A visual cue...<br /> You can also get a device that converts the output from a PC speaker to flash a room lamp. You can even set it to react only to specific frequencies, and tune your specific 'warning' output sound files to those frequencies so other PC output would generally be ignored or less likely to trigger the lamp. You may also be able to get the PC to display a REALLY obvious visual cue when it posts a warning, but if you're watching the TV you might not see it. text/html 2008-01-31T11:48:39-05:00 KM http://www.hardwareanalysis.com/content/topic/70563/#527491 I have this set up on my system. All I did was place a TV tuner card in my PC and run TV through the PC. The headphones and speakers run from my PC as well. This also allows me to record and save anything on TV.<br /> <br /> text/html 2008-01-31T01:49:18-05:00 R S http://www.hardwareanalysis.com/content/topic/70563/#0 Is there a way to hook headphones up to a laptop and TV simultaneously? I use wireless headphones that I have connected to my lcd TV and want to connect them to a laptop as well so I can hear alerts and other things when I'm doing work. I'm not sure what kind of adapter or hardware I would need for this. thanks
