Sound/Midi Not Working in Adobe Flash, YouTube etc. using CMedia sound card

About two months ago, I was playing around with the codecs on my Windows XP machine...I cant exactly remember why, but I think I was trying to install a new DivX one. I installed a few differnet players and codecs until I found the one I wanted. Everything seemed to be fine...until I went to YouTube and noticed that I was not getting any sound. I thought it was an Adobe Flash problem, so reinstalled it, but still no luck. I found that I could play MP3s normally but couldnt play MIDIs or any Flash sounds. It appeared to be playing as normal but no sound came out. I thought it may be a sound card problem (C Media) so I reinstalled the drivers...no luck.

I noticed in Control Panel under "Sounds and Audio Devices" (Windows XP) that my "default device" for MIDI Music Playback was blank and also my "default device" was blank. Even if I selected an option from the drop down list and pressed "Apply" then "OK", the settings would not be saved and next time I go back in, it would be blank again.

I also noticed that the speaker icon in the bottom right hand corner of the screen (in the task tray) had disappeared as well.

I was getting really frustrated and googled the problem and found that this was a very old problem with no resolution.

After playing around and tweaking alot of settings, I finally found the solution with a little help from an old friend RegMon. I found that Windows was looking for two keys in the registry and couldnt find them. These were:

HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NT/CurrentVersion/drivers32/midimapper

HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NT/CurrentVersion/drivers32/wavemapper

It seems that one of the programs I installed then uninstalled when looking for the codec/player that I wanted must have deleted these keys.

Anyway, the solution is that these two registry keys should be set to the following string values:

HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NT/CurrentVersion/drivers32/midimapper should be set to midimap.dll.

HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NT/CurrentVersion/drivers32/wavemapper should be set to msacm32.drv.

If you are still having problems, you may need to reinstall some default audio codecs the instructions found here.

Finally, everything is back to normal again! I can now select my voice playback and midi playback default device and the speaker icon is back in the system tray...and I can watch Flash videos and listen to MIDIs.

  • THANK YOU VERY MUCH 1000 TIMES !!!! I DID POST MY PROBLEM ON AT LEAST 20 FORUMS IN LAST THREE WEEKS AND NONE CAME UP WITH A SOLUTION. THE BEST IS THAT I CAN SEE THAT LOT OF PEOPLE HAS THE SAME PROBLEM AND ARE FORCED TO REINSTALL G.D. WINDOWS, AND YET YOU FOUND A SOLUTION THAT REMOVES THIS PROBLEM IN 30-40 SECONDS. I WAS ALREADY THINKING OF LOSING THIS WEEKEND TO REINSTALL. THANK YOU FOR MY WEEK-END. I ALSO AGREE WITH PEOPLE THAT YOU REALLY SHOULD POST THIS SOLUTION ON MORE SITES SINCE THIS IS OBVIOUSLY A COMMON PROBLEM. I ALSO CALLED MY HP SUPPORT AND GUESS WHAT ---- THEY DID NOT KNOW JACK A.. I WONDER WHAT THEY GET PAID FOR. WELL, MAYBE IN THE FUTURE I COULD HELP YOU WITH SOMETHING SO DO NOT HESITATE TO WRITE ME ON dtlesq@yahoo.com !! God bless you !!!




    Any idea or possible solution to workaround this below would be highly appreciated. I am currently going mad with this issue. God help us all with windows !!!

    Also, I have WMP, Real Player and Quick Time installed and Flash Player 9 as well. Well, your post helped me and gave me an idea where to look in my machine for the problem and I discovered these facts:

    1. My speakers are working fine
    2. My mic's are working fine
    3. My sound card and driver works fine SoundMAX HD Audio
    4. All my players work fine except audio when playing FP9
    5. My windows sound recorder does not work at all
    6. I cannot play MIDI files by default Microsoft Synth and I have to use Quick Time to play it.
    7. I cannot play my default ( and other themes ) system sounds
    8. Also, I can see Microsoft GS wavetable SW Synth when setting Audio Properties but after apply it disappears again.
    9. My all drivers are updated and machine as well.

    So, I did realize that problem is in default Microsoft Windows MIDI Synth like you also found it but after spending hours on the forums and use nets I couldn't find any solution to work around this problem except to reinstall my windows. I also can confirm that this problem have nothing to do with different codec installed like AC3, ffdshow etc.

    Furthermore, there is no any help on HP Support site for this kind of problem.

    SO, IF I WOULDN'T BE ABLE TO FIND WORKAROUND SOLUTION I WILL BE FORCED TO REINSTALL MY WINDOWS AND HAVE AT LEAST 8 HOURS OF "FUN" TO SET UP ALL THE STUFF I HAVE NOW ON MY COMPUTER !!! SOMETIMES I REALLY DO HATE WINDOWS AND THINKING TO SWITCH FOR A LINUX !!!

  • How do i add the strings or whateva im only 11 i dont understand sorry

    By Anonymous Anonymous, at 3:38 pm  

  • i dont have drivers 32

    By Anonymous Anonymous, at 6:30 pm  

  • I am going mad with this problem. I'm sorry; I'm 13 and I don't know how to add the strings. Besides, people say that messing with the registry can screw up your computer if you're not very tech-experienced.

    My problem is that itunes works, fine, but when I get to an internet site like youtube, no sound comes out. At the bottom right of my screen, the sound device item has disappeared and when I go to control panel to sounds, speech, and audio devices, there is no audio device under volume. Someone please help me! I'm going nuts with this problem!!

    Good luck.
