I have the same problems (copying form cdrom, or ripping audio tracks),
but the audio plays just rigth with ALSA drivers.
With OSS drivers I have had some sync problems, so I reccomend the ALSA one.

The only thing which annoys me is really slow playing (70% cpu usage) of
audio-only files with alsa interface (problem _only_ with mplayer, xmms and
alsaplayer all work good), the same plays fine with oss emnulation.

I have posted about it, but nobody responded :-(
