I have never had a problem with the good reliable vlc media player until now. I have since downgraded to 1.0.5 but 1.1.0 inexcusably hiccups audio when I play back an .avi file with a 20,000 kbps total data rate. This is inexcusable because I am running windows 7 on a computer running i7, 12 GB ram etc. and 1.0.5 has never had any problems. I hope you figure this out so I can upgrade, otherwise I am perfectly happy with 1.0.5.
Thanks for all your hard work!

Can you share the file?

Same here on mp3s and flv, ANY of them. Works fine until you stop the stream and then start it again. Then intermittent hiccups that I've never had on any VLC. Worked fine in 1.05

XP Pro, Realtek HD Audio, MSI board, X2 AMD 5400

same here. only since 1.1.0. about every 10 seconds. mp3 files only tested, but i'm sure it's all. winamp works fine.
running win7 64 bit
amd quad core, asus onboard audio

this thread hasnt been touched for awhile so i'm sure it's been addressed, but never know

Try 1.1.2

Hi,
I'm using 1.1.4 and I get audio hiccups playing any file of almost any kind/size (DIVX, XVID, MPG, MP3 etc.), every 5-10 seconds, throughout the play. It also happened with the previous version I had before the update (I don't remember which one, I guess 1.1.0).
Statistics show that a couple of audio buffers and video frames are lost, but it happens only at the beginning and it's not consistent with the hiccups.
I tried configuring different audio/video output methods and combinations but none of them worked this out.
In addition, during x264 720p MKV plays I sometimes get video freezes (audio continues normally, except for the hiccups).
This is what Messages showed:

main warning: output date isn't PTS date, requesting resampling (-40251)

main warning: timing screwed, stopping resampling
main warning: mixer start isn't output start (-58403)
main debug: audio output is starving (165773), playing silence

Hiccups occur when "audio output is starving" of course.
I'm using Lenovo T400 - WinXP, Core2Duo 2.4Ghz with 2GB RAM.
CPU load is 90% idle while playing a file.
VLC CPU Load - 3-7%
Mem Usage - ~60MB (Peak mem around that value)
Page Faults - 357,000 after 22 minutes and rising.
VM Size - ~54MB.
I believe that VLC player is the best player that exists out there, and it's very frustrating that since the new version I encounter this issue.
If I can do anything to help debug this issue please contact me directly through email.

Thanks for your hard work on this player,

I hope you can solve this issue... It's irritating...

I'm having the same problem, I have a Lenovo T400 with XP SP3. I only have the audio hiccups when I am using the discrete ATI graphics card. When I switch to integrated, the problem goes away.

Is your CPU peaking?

Posted: **03 Mar 2011 15:00**

I have just joined, cant find a way to post a question and need to know how to stop the audio from being so high pitched when I play the videos on MSN (the news, the entertainment, etc.) I only joined so that I could fix this and now I dont seem to be able to do this. HELP.....JOAN

Lots of hiccups when playing songs. Every time there is a hiccup there is a input error message on the debugger. The debugger says it keeps increasing pts_delay; when it gets to 4000ms+ the lag stops on that song, next song starts over again. CPU stays between 0% - 2%, Memory 22mb-23mb.

edit: I probably should have started a new thread; but I found this one on google with my same problem. I'm also using a realtek on-board sound card.

From the log, it looks like input bandwidth is insufficient. Not that it makes much sense if you play a local file.

It may be a problem with power management, especially on Windows.

Posted: **14 Aug 2011 17:45**

It happened when I was running two EvE Online clients, it didn't do it when it was the only thing running. It's weird because my CPU usage was below 20% and memory below 40% and the drive was a dedicated media drive, it should have been the only thing using that hard drive.

What can I do if it is a power management issue? Also, can I manually change the pts delay to stay at 4k?
