Issues:Stuttering Audio
From CCCP

If the audio plays, but cuts out or "hiccups" every few moments, there are a few common problems that can cause this:
- Your CPU is not fast enough to play the media properly. You can try disabling the Matrix Mixer (see "Mixer" in the "ffdshow audio decoder configuration" window). A slow computer can cause audio problems even if the picture displays properly.
- The player is not using the ffdshow decoder for the type of audio that is in your file. For example, Nero comes with a decoder that doesn't work properly in our tests, and if its priority is higher than ffdshow's it will be used instead.
- FFDShow might have problems playing badly encoded MPEG-4 audio. This can cause stuttering sound over an optical or digital-coaxial connection, and even no sound at all from the analog sound card outputs. If you encounter this problem with files containing AAC, AAC+, HE-AAC, SBR-AAC, MPEG4, or MP4A audio types, you could try using CoreAAC (available on this page) instead. Add the filter to your player's preferred list, then find the "Codecs" page in ffdshow audio's configuration window. Beside "AAC" in the Format column, change the Decoder from "libfaad2" to "disabled". Don't forget to change it back when you're done watching, and please note that CoreAAC only supports analog output.
