lspci gives me 00:1f.5 Multimedia audio controller: Intel Corp.
82801BA/BAM AC'97 Audio (rev 05) .
module loading:
PCI: Setting latency timer of device 0000:00:1f.5 to 64
intel8x0_measure_ac97_clock: measured 49302 usecs
intel8x0: clocking to 48000

In my opinion there must be a small bug which causes that native ALSA
sound is a bit delayed - A/V statistic shows perfect sync but you
can see that this is not true.

Talking about aoss (OSS emulation on top of libalsasound) - maybe
divx uses OSS in different way then MS codecs so this is not properly
emulated - I will be testing that.
