The VideoLAN Forums

Now when I play a video file with the latest version of VLC, there is no audio. But if I click the video to loop, the audio comes on the second time the video plays, and thereafter. I tried but can't figure it out. Any help? Thanks!

Before you start playback, open Tools -> Messages (set Verbosity to 2), then start the playback. Message log should complain.

VLC_help -- I tried what you said, but it didn't work. In fact with most videos when verbosity was on 2, the audio didn't come on until the third time through. I tried level 1, to no avail, and then when I went back to level zero, the audio still often doesn't come on until the third time through. Ironically, with some but not many video the audio works as it should. Thanks!

It won't solve your issue directly, but if you paste those messages here, we can try to diagnose what went wrong.

1. The first time through (no audio) there are no messages.
2. The second time through (no audio) I get this:
main info: Reparenting an object is dangerous (027cc6c0 -> 02803df0)!
main info: Reparenting an object is dangerous (027cc6c0 -> 02803df0)!
3. The third time through (no audio) I get this:
main info: Reparenting an object is dangerous (027cc6c0 -> 02803df0)!
main info: Reparenting an object is dangerous (027cc6c0 -> 02803df0)!
main info: Reparenting an object is dangerous (02803df0 -> 027cc6c0)!
main info: Reparenting an object is dangerous (02803df0 -> 027cc6c0)!
4. The fourth time through (AUDIO) I get this:
main info: Reparenting an object is dangerous (027cc6c0 -> 02803df0)!
main info: Reparenting an object is dangerous (027cc6c0 -> 02803df0)!
main info: Reparenting an object is dangerous (02803df0 -> 027cc6c0)!
main info: Reparenting an object is dangerous (02803df0 -> 027cc6c0)!
main info: Reparenting an object is dangerous (027cc6c0 -> 02803df0)!
main info: Reparenting an object is dangerous (027cc6c0 -> 02803df0)!
The fact that I now get audio only on the fourth time through is new. I used to get it on the second or third time through.
Thanks!

Could you open messages before you start playback, and paste them here after ~3 seconds of playback? (so I could see the audio initialization messages)

Set at level zero, this is typical of what I get: 1st time through (NO AUDIO) = no messages.

2nd time through (NO AUDIO) = main info: Reparenting an object is dangerous (0164dc98 -> 016b6610)!

I don't know if this what you want. Please advise. Thanks.

Set verbosity to 2, then start playback. And if forum complains about too long message, then paste text to pastebin (and share the link to that).

Where do I find the pastebin? Thanks.

Okay here is the Pastebin link. No audio first time through. Audio Yes the second time through. Thanks!

Again, open the Tools -> Messages before you start playback. Otherwise it won't collect all messages.

I figured out what had gone wrong. I went to a place I had never been before: Tools > Audio > Preferences > Always Reset Audio Start Level to > . When I got there the setting was at zero. How it got there, I don't know. The reason there was audio the second time I looped the video through was because on the first pass, I used my scroll wheel to increase the audio level. It had no effect as the first pass through was playing, but the new level I'd set kicked in on the second pass. All I did was to reset the audio start level to 150%, and voila, no problem. Thanks for your help.
