I built my computer with a Chaintech 7NJL6 mobo, which is suppose to have  C-Media AC97 onboard sound. After getting all the bugs worked out(or so I thought) I have no sound. I have no little speaker in the task bar and windows does not find/recognize any sound devices. But I can open the generic CD player manually and play a audio CD. So my speakers do work and my drive is reading the CD. Any help would be appriciated.Goto start/PROGRAMS/accessories/entertainment and open volume control from there. Make SURE nothing is MUTED, except the microphone. You say you can play an audio CD OK. What are you not getting sound in, everything else? Did you see the sound device in the device manager?When I go through the start menu andd try to open the volume control, My computer thinks(little hour glass) for a minute, then nothing happens. My sound shows up on the device manager, but all programs tell me that no suitable/or no playback device is foundHave you downloaded the latest drivers from here?

http://www.chaintechusa.com/tw/eng/Download/dl_desc.asp?DCSNo=15&PISNo=277Yes I have just RETRIED downloading the drivers from Chaintech's website, but it is the same thing that is on my disk that came with the mobo. And still computer says no playback device is installed. But it shows up in device manager and says it is working properly.Try deleting ALL of the sound drivers in Control Panel/Device Manager and reboot. Do you have the little icon for sound in the bottom right corner (the speaker)?I have deleted the drivers and rebooted, no luck there. But I was wondering, If I have programs on the computer that run with directx 9.0 ( which doesn't work on windows 98 ) if that might be the problem?DirectX 9 is a video thing. I don't know if that would have anything to do with your problem. I say send it back  . Yes I know, its a new mb. Bu thtings happen and you may have a faulty board. It would not be Chaintechs first.Are we to assume that you are running win98 on this machine?Yes running windows 98 SE, I just don't understand how the device manager can say the device is working properly but windows doesn't find any playback devices!Go into control panel/multimedia and see what can be set up from there. While in there, tick the check box to show volumn control icon in system tray.Please read the entire page before MAKING a suggestion. I appreciate everyones advice but I seem to be getting some reptetitious answers to my riddle.My reply is hardly "reptetitious". I see nowhere in this page that it has been suggested. Why don't you try it, or at least state that you have.well I guess it just seems like everyone I have talk to has mentioned the little speaker icon in the task bar. In the start menu under multimedia, the playback and record page is grey'd out. In the lower corner where it says "check box to display volume control in task bar" is checked but also grey'd out.Are you certain that the volumn control program is actually on your machine. Go to start/find and type in sndvol32 - it should be in c:\windows. When you loaded the software for your sound device it probably created a directory and placed files there. If it is SB or Ensonique compatable, the directory would be sbpci. Locate the proper directory; See if there is a setup program for it. If so run it.
