Severity: normal
Hi all,
In vlc sometimes the audio is there, sometimes not. This is from a vlc
-vvvv session of a media file I was playing :-

I am usually able to play the audio after using the slider (for going
forward and backward) and somewhere get the audio.
Looking forward to know what the issue might be ?
I also took the liberty of getting pulseaudio details in case if they
are helpful to figure this out. I have no idea if the bug is in vlc or
pulseaudio or the codecs in libavcodec.
