Hello While watching hi-definitions video, I've noticed a lots of audio drop-outs when watching movies with raw ac3 on spdif output (ac3 decoding is done by my Yamaha amplifier).
Long story short, I've been able to reproduce the problem when playing a raw ac3 stream with ac3dec while loading my SATA drive. I.e. run simultaneously: - ac3dec -C en.ac3 - md5sum *.avi > /dev/null (on a sata drive) In this case, the audio is horribly chopped. So far, I've noticed that: - Playing ac3 while loading PATA drive (same commands) works perfectly - Playing PCM (with mplayer) on spdif while loading SATA leads to high frequency noises (like a constinuous scritch-scritch) Since this problem is related to SATA, I don't know if it's a kernel bug or an alsa bug (or both ??). My system: - Advanced Linux Sound Architecture Driver Version 1.0.11rc4 (Wed Mar 22 10:27:24 2006 UTC). - AMD Athlon(tm) XP 3200+ - spdif output on Sound blaster Live 5.12 (emu10k1 driver) - Debian kernel 2.6.17-2-k7 v 2.6.17-8 (roughly 2.6.17.11) Does anyone know how to fix this problem ? Should I log a bug to alsa or kernel ? Thanks ------------------------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
