No, but I feel your pain, having just wrestled with this recently.
Could play an ogg file on startup, but after recording a file with
krec, all players failed to open the audio device for playback of any
sound file, even with full duplex enabled, or if krec was stopped.
Some kind of locking? Guess you get just one shot at using the
soundcard anymore. Couldn't find an answer in googleland either...
