Hi, Audio playback behaves as if muted except for roughly periodic short, sub-second bursts. I’ve observed this playing audio files using Firefox, Chromium, VLC, and mplayer. When playing video the picture is likewise affected, but disabling audio in VLC fixes it.
mplayer complains about the requested audio codec (see below). Any help appreciated. $ mplayer SONG59B.MP3 MPlayer SVN-r37520 (C) 2000-2015 MPlayer Team Playing SONG59B.MP3. libavformat version 56.40.101 (external) Audio only file format detected.
