Reinstall Audio Codec Drivers / Intel IMA Adpcm 11 Codec Vista Download
On installing Windows XP and 2000 on a fresh new machine, the default sound codecs are installed for each sound device that will play sound in that Windows machine. However, if Windows does not detect a sound card, these codes might not be installed at this point. So, if you were to install a sound device and/or a sound card later on, your sound card driver might not detect these default codecs and/or install them if required. This is true for most low-end sound card drivers.
Thus, most likely, there will be no sound output from your system. To check if your system is undergoing a missing sound codec situation, go to Control Panel -> Sound and Audio Controllers, and then click on Hardware tab. Then select the Audio Codecs entry and click on Properties tab. If you have this error and you can’t hear any sound, you will most likely find only about a couple of codecs entered in the listing, particularly if you have not applied a registry patch to fix the issue. Actually, even a registry patch can’t fix this problem if the *.acm files are missing.
However, you can manually install the required codecs – just follow the steps given below.
· Click on Start -> Control Panel.
· Click on Add hardware applet.
· On the Add Hardware Wizard, click Next.
· Select “Yes, I have already connected the hardware” radio button and then click Next.
· Choose “Add a new hardware device” at the bottom of the list and then click Next.
· Select “Install the hardware that I manually select from a list (Advanced)” and click Next.
· Select “Sound, video and game controllers” from “Common hardware types” list and click Next.
· Select “(Standard system devices)” from “Manufacturer”.
Note: To install or reintall video codecs, select “(Standard system devices)” from “Manufacturer” and “Video Codecs” from “Model” instead.
· Click on “Have Disk…” button.
· Click Browse button in the Install From Disk dialog box. Navigate to folder C:\Windows\System32, and then locate mmdriver.inf file. Highlight mmdriver.inf and click Open or simply double click on mmdriver.inf file, then click OK in the Install From Disk dialog box.
Click on “Continue Anyway” button if a warning about logo compatibility pops up.
