[arch-general] audio skipping frequently with vlc
I recently noticed then when playing DVDs and other audio files through VLC that the audio skips frequently. It doesn't get out of sync, just goes mute for a split second. I tried the past few versions of VLC but it still happens, so I guess it's one of the dependencies, but I'm not sure which. Has anyone noticed/fixed this?

I've also this, specifically when playing music via amarok and KDE setup using phonon-vlc as preferred and specifically just before and after song change. As a result, I still use phonon-xine until this is fixed. -- Divan Santana

I forgot to mention that this doesn't happen with totem, so I guess it's a ffmpeg thing? I tried downgrading vlc, ffmpeg, and alsa-libs/alsa-utils. Nothing helped.

I use both VLC, and Amarok with phonon-vlc, (on Arch; since phonon-vlc emerged around June or August) and it's been working fine the whole time. (Except that Amarok with any backend, for me, (-xine, -gstreamer, -vlc) used to sometimes crash around song-change and now sometimes just does weird-but-predictable things around song-change. I think that's unrelated.) -Isaac

What output are you using? I'm on HDMI. Here is what happens in VLC with a verbosity of 2 for every skip: [0x3415df0] main audio output debug: audio output is starving (21344), playing silence [0x3415df0] alsa audio output debug: recovered from buffer underrun I've found some forum postings on this, but can't find any definitive solutions, certainly nothing that's worked for me.

Built-in laptop output (both internal speakers and headphone jack work). lspci calls it "Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02)". Working with either plain ALSA or Pulseaudio in force. (Modulo an unrelated default-muted-channel issue that I fix every boot so I can hear anything.) My laptop has a Mini-DVI port for which I have no adapters, and USB and Firewire ports but e.g. I have no USB Audio devices, so I don't think there are any other output modes I can test.

Is that log output from VLC? Kernel? Something else?

Certainly you're having a problem! I'm just hoping that the info that not everyone has the problem is helpful for debugging (or I could post some log if you think it'd help). FYI, sometimes I get skipping due to system load (additionally DVDs, being optical media - high latency -, are often a bit more annoying) -- but I can deal with these whenever they occur by closing other open programs. -Isaac
