The VideoLAN Forums

Since updating to 2.1.2, every 30 minutes or so of playback, audio drops out for about 1-2 seconds. Sync is still fine. Many different file formats affected. OS X 10.6.8, MBP 6,2.

Sounds the similar to mine. See my post yesterday titled "Version 2.1.2 with OSX10.9 Crash whilst playing from NAS"
I've downgraded to 2.0.9 and all problem stops.

Seems quite different actually (from what's described at https://forum.videolan.org/viewtopic.php?f=12&t=115932). I have no crash, and no pause or other problem in the video. Just the audio cuts out briefly, as described.

Please upload a VLC log.

Sorry for this long reply; couldn't find an upload function in the application or on this forum interface.

I assume the problem might be near the end, where it says "main warning: playback way too early (-161260): playing silence"?

It looks like this is only the log for the start of file. Interesting would be the parts where it actually drops audio. "playback way too early" might happen on the start of file, but if you see this or something similar in the middle of the playback, this might be the issue.

there you go. i am using the nighty build 2.2.0. it was happening with 2.1.2 also but maybe its the video file. i dont know.

Looks like you are using digital surround output. And this actually works (aka: you hear normal output, and audio just drops out 1 or 2 seconds from time to time)? Over which time period was this log recorded, approximately?

I'm facing the same problem with versions 2.1.2, 2.2.0 (nightly build) - using digital surround output through hdmi and optical external output from mac book to av-receiver. Problem occurs with different video files on dolby d and dts.

On version 2.0.9 i have no problems.

Any news regarding this issue ?

I have the same issue with intermittent audio dropouts on DD5.1 over HDMI with the same 'way too early, playing silence' log messages. OSX 10.9 VLC 2.1.3. Any news of fix or workaround ?

OK just downloaded VLC 2.1.4 and issue still present. Audio drop outs of less than one second, approx every 5 minutes. Tried several H.264 mkv files, all exhibit the issue. Both DD and DTS surround sound tried, audio device = HDMI (encoded signal). Other than this problem, video and audio is excellent in every way.

OK I tried the nightly build vlc-2.2.0-x86_64-20140219-0113.zip 2014-02-19 01:15 VLC media player - 2.2.0-git Weatherwax

This seems to have cured the problem entirely ! Very happy.

TB.

I've been having this issue for a while, including with the latest/final 2.1.4 build.

I'm running 10.9.2 on a 2011 Mac mini connected to a Logitech Z-5500 via optical. It only happens with video clips that have encoded audio (DTS or DD 5.1).

Anyone have any advice?

I guess, this was never solved - still the same problem in Version 2.2.4 Weatherwax (Intel 64bit)
