Bad sound occuring when sending audio to second monitor

[harleynut97]

Hi, I hooked up a second monitor to my computer yesterday and I'm really disapointed in the sound quality coming thru. The video is coming thru perfect. This is my set up...

1) windows 7 home, MSI p67a-c43 motherboard with integrated audio- realtek ALC892, nvidea gtx 550 TI. I have my regular computer speakers attached to the 1/2" speaker connection port (green) on the computer.

2) The TV (second monitor) is a vizio E320vl . I have tried changing all of the audio settings on the TV ( like sound filters and pcm/dolby digital settings that are on the tv to try and correct the problem to no avail. There are a number of hdmi ports on the TV, and one of the hdmi ports (the one it is plugged into) does have rca audio ports next to the hdmi connection, but the audio is being sent via the hdmi and these are not being used.

3) The video card has 2 dvi ports and 1 mini hdmi. My regular computer monitor is being hooked up to the dvi port. and BOTH the audio and video to the second monitor is sent to the 2 nd monitor using the mini hdmi. I am using an hdmi extension because of the distance from the computer (about 16 feet from the computer)

Here is what is happening with the audio- while I am getting audio to the 2nd tv ( by changing the playback devices default switch to the second monitor that displays in the computer sound settings, the audio sounds very different from what it should. The best way to describe it is almost like very tinny sounding... almost like listening to it thru a can Music sounds really bad. There is no static or noticable distortion, just sounds bad in comparison to what comes out of my very cheap computer speakers (playing the same source material). It also sounds awful compared to the regular broadcast sound coming out of tv speakers.

Any suggestions as to what I should try changing would be appreciated. - Carl

When you use HDMI and HDMI audio, the audio is generated by the sound chip in the Video card, not the regular PC sound chip. I don't know if the video card has any sound adjustments, but check. Also check with NVIDIA for any updated drivers for the video card.

Thanks for the reply fireberd. Been busy with Thanksgiving so haven't been able to reply back. I didn't realize that audio via hdmi is coming from the video card audio chip rather than my onboard audio.

I did what you suggested and updated the video driver. Unfortunately still have the same problem. There does not seem to be any settings that I could find on the nvidia control panel that pertained to audio other than allowing you to enable hdmi audio to the source that the cable is attached to. They basically tell you to adjust settings via the operating system.

I am going to try and run RCA directly to my 2nd monitor (TV) and not use hdmi audio and see if that is any better, but I need to go out and get longer cables than what I have right now. This second monitor is about 15 ft from the computer.

The sound continues to be "tinny" sounding and definitely much quieter that what I hear with broadcast TV coming thru the same speakers.

I've checked all the levels in windows to assure that I have them turned up all the way. Any other suggestions would be appreciated- Carl
