Laptop HDMI connection to A/V receiver playback device is not producing any sound

I have one issue which hasn’t been resolved from the past several days. My laptop was connected to an A/V receiver via HDMI. I connected the cable from the receiver to may sony LCD TV for output. Now I am familiar with how to modify the playback device. The problem is I can see the picture but not getting any sound from the receiver speakers/subwoofer. I can only hear the sound from my TV speakers. Is there any way to change the playback device so that I can hear the sound from A/V receiver instead of Sony LCD TV? I hope that someone might have found the answer for it. So don’t delay to post it with a appropriate solution. Thanks in advance for any kind of help and suggestion.
