Sound through the hdmi cable i can hear in monitor speakers but not in external

Hello,

Sound through the HDMI cable I can hear in monitor speakers, but not in external speakers. I also have a cable connection via sound card to external speakers.
I want it to listen to music through external speakers.

Please help!

Thank you, Alex

go into sound (im assuming your in windows) in the control panels, and set speakers as the default device

just to make sure it looks somewhat like this? http://i.imgur.com/UaDwq.png

the Nvidia is your video card, so it will send sound through the HDMI cable. Try disabling that option in the Sound menu. Set you default audio to one of the other ones on the list and test. Check your Device Manager and make sure you have the sound card driver installed. Verify you have the green cable connected to the right port. Try connecting the green sound cable into your motherboard and see if you can get sound from there, instead of using the sound card. Make sure your speakers are turned on and sound volume is up.

I also tried this option but without success. In test is no sound through speakers. I have last update.
