Audio stuttering in 1.1.5, but not 1.1.4 and earlier
Posted: 13 Dec 2010 14:11
I'm having severe audio stuttering issues using vlc-1.1.5-win32. The audio stuttering happens on every file I've tried that has audio content. I've tried MKV movies, Xvid movies, MP3 audio files, and M4P audio files. The stuttering occurs persistently on all of them. In every case the files were stored on the notebook's internal hard drive and not streamed via networking. The same files played without stuttering in a 3rd party media player.
I've downloaded fresh copies of VLC 1.1.5, 1.1.4, and 1.1.3, and cleanly extracted them to separate folders. VLC 1.1.3 and 1.1.4 both play files without audio stuttering. Only 1.1.5 exhibits stuttering.
I have tried resetting all preferences, just in case, and I've also tried every Audio Output Module and restarted VLC after every change. They made no difference... well, except for ones like Dummy Audio Output Function which silenced VLC altogether. I also tried using USB headphones rather than the notebook's speakers, to no effect.
Here's a copy of the VLC messages.
Any ideas on where the problem lies?
