Audio pitch is too high/plays a little too fast

[TigerNightmare]

This problem seems new for 1.1.5. I've noticed that when I play songs, they sound wrong. The pitch sounds just a little too high. I did a few experiments playing the same file in VLC and Media Player Classic. With my audio tests, after syncing the audio, VLC overtakes MPC quickly, and after tapping my spacebar to re-sync, VLC overtakes MPC again. I tested video side by side on separate monitors and the problem is similar but not just speed that's too fast, but inconsistent fluctuating, with VLC overtaking MPC, then slowing down enough for MPC to catch up, but eventually overtaking MPC completely. The effect is very subtle and very difficult to notice unless you have a certain familiarity with the sound of voices or how a song is supposed to sound. VLC also lets out significant glitchy pop sounds every so often.

Does it help if you change audio output module?

Tried every mode but VLC plays faster in all of them. Interesting thing happened when I used file output mode. I opened a song with VLC, then I opened the same song and the audiofile.wav that it created in Adobe Audition. The original file's length was 1:43.612 and the new file was 1:43.561. I played the new file in Audition against the original file in MPC and they were able to stay synced the entire time.

Does Tools -> Messages (set Verbosity to 2) show some messages during playback?

Yes. At first I thought it was because I encode all my music files under VBR, but this was from playing an uncompressed wav file.

[VLC_help]

Yep, the timing goes crazy. But unfortunately I don't know why (log doesn't tell). But I would guess this just another form of power saving timing issues that seems to bother VLC 1.1.5

[TigerNightmare]

I downloaded the most recent nightly branch build and the timing/pitch issue seems to be fixed. However, something that I think was a problem since at least 1.1.4 is still happening and it happens with all audio files but it's really more noticeable if you try to play really short files, like Windows event sounds that are mostly under 2 seconds. Part of the beginning and part of the end gets lopped off and some files don't even make a sound (like this one, which can cause VLC to crash if I enable loop one playback and click play: http://www.zot.org/~hamish/sounds/sosumi.wav). I know the nightly builds aren't officially supported, but this is still an old problem.

Short files are problematic for VLC since with current design VLC core doesn't wait for vout or aout.

[Jean-Baptiste Kempf]

I downloaded the most recent nightly branch build and the timing/pitch issue seems to be fixed. However, something that I think was a problem since at least 1.1.4 is still happening and it happens with all audio files but it's really more noticeable if you try to play really short files, like Windows event sounds that are mostly under 2 seconds. Part of the beginning and part of the end gets lopped off and some files don't even make a sound (like this one, which can cause VLC to crash if I enable loop one playback and click play: http://www.zot.org/~hamish/sounds/sosumi.wav). I know the nightly builds aren't officially supported, but this is still an old problem.

Test 1.2.0-git
it should be fixed.

[TigerNightmare]

I guess the timing problem being gone was a fluke. I have no idea how it was working right before, maybe it has something to do with a windows update that was installed the last time I shut down. I'll be trying out nigtlies and testing files every now and then and will post again if I find any improvement.

[TigerNightmare]

I'm noticing a pattern. It's like there's a sort of state that my computer will be in that's not easy to define, this part of memory is being used by program X and program Y and Z are dormant in the page file or whatever, something like that. I would wake my computer up, download a branch and overwrite the previous installation and it would work fine in testing. Then, hours and several files later, when I try to play something else again, it plays fast again. If I try to upgrade to a new build right after noticing the problem, it will still play fast. I've used the 12/19 and 12/21 branches of 1.1.6 and the latest trunk of 1.2 to test.

[TigerNightmare]

Just downloaded today's trunk of 1.2. The speed problem seems to occur when I open VLC after a fresh reboot. If I put the computer into S3 standby mode and then wake it up, VLC will play at normal speeds and the debug error messages go away. It seems to be a consistent temporary fix but I don't understand why standby would do anything.

[VLC_help]

It will prolly adjust your power saving options in some way.
