Vista - DSP Group TrueSpeech™ Audio CODEC

Ive been trying to use the voicechat feature in Yahoo messenger but i keep getting the message "Your computer does not support the required audio compression format". I did some snooping around and learnd that i need to have "DSP Group TrueSpeech™ Audio CODEC " to use the voice chat can anyone help me aquire the needed codec?

Hi. This is a pain to do, but follow to get up and running:

The DSP codec can be installed on Vista using the following procedure:
1. Acquire tssoft32.acm and tsd32.dll at
Codec-Download.com - Downloads
The Download link is half way down the page.
2. Open the Windows\System32 directory
3. If tssoft32.acm is present, rename it tssoft32_old.acm. Either way, proceed to the next step
4. Place tssoft32.acm and tsd32.dll into the Windows\System32 directory
5. Create the following registry entry:
a. Folder (you may need to create some of these folders: KEY_CURRENT_CONFIG>Software\Microsoft\windows\CurrentVersion\Drivers32\msacm.trspch
b. Set REG_SZ value to: tssoft32.acm
c. No need to reboot, just close regedit
6. You can verify that the codec installed correctly by going to WMP 11\Help and clicking on “Technical Support Information”. A webpage will open listing all the codecs installed. If tssoft32.acm is listed, you’re set!

where do i have to create the folder in the system32 file or in a different spot

OK, I found an easier way:

1. Open Windows Explore goto C:/Windows/System32 and Rename tssoft32.acm to tssoft32OLD.acm

2. Click Here to Download tssoft32.acm save in C:/Windows/System32 folder

3. In Control Panel, go to Add Hardware.

4. Click Next and after it searches choose Yes, I have already connected the hardware Click Next.

5. Scroll down to the bottom of the Installed harware list and choose Add a new hardware device Click Next.

6. Choose Install the hardware that I manually select from a list (Advanced) Click Next.

7. Choose Sound, video and game controllers from the Common hardware types list. Click Next.

8. Click on the Have Disk button.

9. Click Browse

10. Navigate to the C:/Windows/System32 folder

11. Choose $winnt$.inf Click Ok. (if you cant find that file try mmdriver.inf )

12. Click Continue Anyway if you get a warning box.

13. Select DSP Group TrueSpeech Audio CODEC from the list. Click Next.

14. Click Next again to install.

15. Restart if necessary.

16. Done! Voice should now work if you followed the steps correctly...

Thanx coolchris..
IT works like a charm!

EDIT: This IS the ONLY workaround that I could find throughout the net for this problem! And this codec is used by various types of medical transcription software..

You are Welcome. Glad to help.

I have a vista hp pavillion dv9000 which was bought in oct 2007.. my problem is I'm trying to convert dvd's to wmv so they can be used on the Disney Mix Max I have all the programs they say you need but I keep getting the message the requested audio codec in not installed on this system (0xc00d0bc2) what is that? I have been all over the net trying to find it but after I download it it says I have a newer version already installed.. where do I find it and get it installed. I really need laymen terms as I'm not real good on the computer and some terms make no sense to me. Any HELP will be greatly appreciated..I'm using the Windows Media Encoder

I'm not sure what this system is. Its the home premium HP Pavillion dv9000

Hi there and Welcome. Firstly I think you posted in the wrong forum thread, but nevertheless Ill try and help. What you need for Vista is this codec pack.

Download Vista Codec Package 4.5.8 Final - With this package installed, you shouldn't need to install any other codec or filter - Softpedia

This should give you all the codecs you need on your system for converting.

Thank you for your help but I tried to install that and it tells me c:users mary desktop vistacodecs_v458.exe is not a valid win32 application I don't know maybe I'm doing it wrong. What forum should I be going to? Everytime I type into google and ask for help this is the one I keep going to. I really do appreciate your help though as this thing is really starting to drive me crazy. Mary
