Wav files are played missing the first 0.10 seconds

Every wav file I play misses the first 0.10 - 0.15 seconds with every media player I tried except with Audacity which plays them fine. This problem happens even with fresh new users. I erased my root partition and installed everything again but the problem remains. Please any help.

Re: Wav files are played missing the first 0.10 seconds

I have the same problem: it looks like a problem with alsa.
It's funny because if I use the oss compatibility layer, the files play just fine.

Re: Wav files are played missing the first 0.10 seconds

I tried to search with google, but couldn't find anything.

What card do you have?

this is mine:

using snd_intel8x0 as driver

I'll try fiddling with some module parameters tonight

Mine is this one:

But I got no idea how to know which the driver is

Re: Wav files are played missing the first 0.10 seconds

Ok, I made some other checks.
I was misled by mplayer: mpg123 using the alsa output module plays mp3s fine.
So it seems it was a coincidence and both mplayer and aplay have this problem.

Just to know, what programs did you notice the problem with?

Beep-Media-Player
Exaile
Totem
VLC
aplay file.wav
gst-launch-0.10 playbin uri=file://

I reported the bug in alsa https://bugtrack.alsa-project.org/alsa- … hp?id=3979 but no answer yet

Re: Wav files are played missing the first 0.10 seconds

I have the same problem. mpg123 and audacity work fine, but all others I've tried (mpd, aplay, mplayer) fail. Where's the problem, so it can be fixed?

~ $ cat /proc/asound/cards 
 0 [Intel          ]: HDA-Intel - HDA Intel
                      HDA Intel at 0xfebf8000 irq 22
~ $ hwdetect --show-sound
SOUND  : snd-mixer-oss snd-pcm-oss snd-hwdep snd-page-alloc snd-pcm snd-timer snd snd-hda-intel soundcore

Re: Wav files are played missing the first 0.10 seconds

Hello people

i've the same problem, fortunately i only need playing short wavs in IM programs, so i simply added 0.1 seconds of silence to these wav files.

//edit
Do you use any sound deamons?
i've noticed this only happens when playing wavs if i don't use any sound deamon. I tried starting esd and playing the wav using esdplay works normally - no bloody gap at the beginning of the sound.

Re: Wav files are played missing the first 0.10 seconds

I also have this problem, playing "Front_Center.wav" in aplay gives me "-ont Center" not a major issue, but it is annoying

Re: Wav files are played missing the first 0.10 seconds

I've got similiar problem, but it happens on all audio files. It is quite annoying when you're listening to few connected together music tracks (live recordings for example). I suppose it may be caused that player requires some time to close current file, and open the next one, but there should be some prefetching or something to avoid such situations... But I am still a begginer, and I may be wrong

Some applications are WYSIWYG, and some are WYSIWTF.

Re: Wav files are played missing the first 0.10 seconds

This issue is resolved for me with the latest release of alsa. See here: http://bbs.archlinux.org/viewtopic.php?pid=413985.

Re: Wav files are played missing the first 0.10 seconds

one small step for an alsa developer, one giant leap for me
