I reviewed your post and I understand that you want to know the installed audio codecs on your computer.
Don’t worry, I assure you I will try my best to get this sorted.
The audio codecs depend on the audio player you are using. One way of checking is through any version of Windows Media Player although the button link is in rather a hidden away location. Open Windows Media Player and if you don’t have a toolbar menu visible right-click towards the top of the program to bring up the context menu. Go to Help -> About Windows Media Player, then click on the Technical Support Information link at the bottom. This will open a webpage that lists several bits of information including installed audio and video codecs.
I hope that answers your question and you have a great day!
