Can someone please enlighten me on how to reinstall .acm files. I noticed that my sound was not as great as it used to be so I tried to reinstall that drivers and that did not help. I ended up going and opening up the device manager and removing all my audio codecs. Well long story short I was able to reinstall my audio drivers and fix my problem but int he interum I can no longer play audio cds through WMP, this isn't a big issue but I need that for other things. Thanks for any help you guys can offer.
