Comment 4 for bug 792769

I did more tests:
1) When my PC is idle, I don't see problem, Audacity plays OGG files OK.
2) When my PC is not idle (I run BOINC cloinet, so my PC is never idle but has always load with low priority), I see problem with Audacity and OGG files under this condition.
3) When I load file in safe mode (copy), OGG is played without issue (I cannot replicate the issue)

I noticed today once, that only one of OGG channels was shifted in time. One channel (left?) finished in time but right channel was played when waveform displayed silence.
I noticed today that channels were not synchronized (like right channel was delayed after left channel, it sounds like an echo.)

To replicate the issue:
1) run PC with some load, it can be BOINC client or some benchmark, or something else.
2) open OGG file in Audacity in fast mode (direct play from file)
3) play the file and hear the music, watch volume level indicator. Music sample should have at last 2 minutes. Longer sample has higer chance to trigger the issue.
