sound problems with rhythmbox

[Tim Welch]

  I'm having problems using rhythmbox while playing doom 3 or any of the
quake series. If rhythmbox is running in the background, sound in the
game is lagged by about 1-2 seconds (i.e.. shoot, enemy dies, then hear
gun firing). This does not happen with other media players (xmms, moc,
mpg123 tested). Why does rhythmbox have that effect? I'm using the OSS
sink.
