Hello,<br><br>I could use a little help on a weird sound issue I'm struggling with :<br><br>
1. Description :<br>------------------------<br><br> When playing audio files with vlc, the sound has from few to many "micro-interrupts"<br> (less than 1/4 of a second), randomly but frequently (so this is not hard to<br>
reproduce). This seem to occur :<br><br> . with any file (I can pick a random audio file to experience it)<br> . with either mp3 or flaac encoded files<br> <br>Note : <br><br>the problem occurs with mplayer as well (either with oss or sdl audio output (although sdl seems to have less "interrupts").<br>
<br> but<br><br> . not with ffplay<br> . apparently not with xine<br> . apparently not with amarok<br>
<br>-> so I doubt this may be a harware or a driver issue.<br><br>and on a almost idle 4GB RAM machine running only KDE-4 and firefox-3 <br><br>no hints shows in /var/log/messages<br><br>Here's what vlc in debug mode says when sound drops :<br>
<br>main audio output warning: PTS is out of range (16139), dropping buffer<br>[0x80883fd78] main audio output warning: output PTS is out of range (67888), clearing out<br>
[0x80883fd78] main audio output warning: PTS is out of range (-9952), dropping buffer<br>[0x80883fd78] main audio output warning: PTS is out of range (-36062), dropping buffer<br>[0x80883fd78] mpgatofixed32 audio output debug: libmad error: bad main_data_begin pointer<br>
<br><br>2. Config :<br>------------<br>
<br>I'm running :<br><br> . 8.0-STABLE FreeBSD amd64<br><br> . full zfs (no ufs) (files are on a "slow" disk pool (5400 rpm) but moving<br> them to the "fast" system disk (7200 rpm) doesn't change anything.<br>
<br> . Tweaking drivers latency options (like hw.snd.latency) doesn't change anything either.<br> <br> . on a (bios up to date) P5Q3 ASUS motherboard<br><br> . with snd_hda sound driver<br><br>Thanks.<br><br>
