    Hey guys, the title is pretty much self explanatory... I'm looking for a way to output sound from my Alienware M17x r4 through jack and HDMI at the same time... i've googled a lot but all i could find is that it either can't be done, it can be done via some third party program, or it could be done by using his method:
    1.Open Sound panel
    2.Select Speakers as the default playback device
    3.Go to the "Recording" tab
    4.Right click and enable "Show Disabled Devices"
    5.A recording device called "Wave Out Mix", "Mono Mix" or "Stereo Mix" (for me on my alienware it was "What u Hear") should appear
    6.Right click on the new device and click "Enable"
    7.Right click on the new device and click "Set as Default Device"
    8.Double click on the new device to open the Properties window
    9.Go to the "Listen" tab
    10.Click on the "Listen to this device" checkbox
    11.Select your HDMI device from the "Playback through this device" list

    The last method actually worked perfectly, but it produced an echo sound ... the HDMI was delayed compared to seakers (jack output).

    So is there any way to get jack audio and HDMI audio run at the same time properly? if nothing else, isn't there any way to eliminate the echo sound from the solution I found?

    Thanks, Pistino01

    I'm guessing the reason for the echo is this:

    In a laptop, the external displays (e.g, HDMI in this case) is handled by the Intel graphics, or iGPU - even with a dedicated/discrete graphics card.

    In a desktop with an add-on graphics card, I think some cards have a dedicated sound chip for the HDMI controller for playback. In this scenario, you would be using two different, dedicated audio controllers (one from graphics card, the other from onboard audio or sound card), instead of sending the audio from a single chip to two different output devices.

    I have the feeling that the sound chip on your laptop is not capable of pushing the signal to the two different output devices without the delay you're experiencing.

    You may have already come across this in your search, but here is some info.
