Hello Again, I am less scattered today. I have restored some damaged files on the system that were unrelated to my sound problems but are indicative that I screwed up big time. I think I have now narrowed the problem to the following. But first a deja vu. I lost everything a couple of years ago and one thing was another list that dealt with specific audio problems. Some people are here I hope that remember that one. Anyway it seems to me that I had a similar problem then and solved it so I would like to access the archives. Please write me off list if you know what I'm referring to. Anyway here goes. 1. The problem started with a conflict between mmtask and wstream.dll. This caused a totally unstable system. I renamed wstream.dll to wstream.d and eliminated the crashing problem but that may have killed my sound. I restored wstream but the crash problem returned so the solution is not in that direction besides there were still no system sounds. 2. The version of directx on this system is 4.09.00.0902 which I think is version 9b running under win98se. My old system was directx 6 running under win98 (not se). I don't think directx is the source of the problem though (hope). 3. The problem seems to be with Crystal PnP Audio System CODEC. Systems resources reports that the driver is not installed although it is on the harddrive and it also says I should continue to use it !?!!!. Also it sometime says that another device is in control of the sound card. It would be nice if that is all I have to do (ie. reinstall the drivers) but I don't think so because there is a disabled device - ms gives no info on what it is but it is a crystal drive of some sort. Ms also identifies "unknown problems" - and they call that a diagnostic!! The Crystal FM synthesizer works (but not the microsoft synthesizer) and the midi mapper works - so the sound card produces sound. I have however no system sounds or sound from the cd r/w. 4. The problem seems to be related to giga synth which I have since uninstalled. The wstream seems to have been used by that program at least. Question - is there anyway of finding out what programs might be using wstream.dll. Question - my sound troubleshooters do no work under help. They offer me a choice of problem (eg. no sound) but when I click on next I get a blank screen. This might mean corrupt help files but it might also point to the Crystal plug and pray situation above (i.e. no sound device). 4. Does anyone know what a file called dxm6patch (p_981116.exe /Q:A) is? This loads at startup. Sorry to be so long here. All I could afford was this used machine and I have no manuals and have yet to crack open the case. (ah. so many errors to make, so little time) The machine is a dell optiplex gx1 with pent2 400. My virus scanner is up to date and the machine is clean. I even used online ones just in case. Sad to say it appears to be pilot error on this one. ===== __________________________________ Do you Yahoo!? Yahoo! SiteBuilder - Free web site building tool.
