Aha! I knew I remembered something about Adaptec and the envy24 chipset. Check this out: http://www.staudio.de/kb/english/conflicts/index.html Granted, this is the ST Audio card and a 2940 but the chipset is the same on the audio card and the 29160 is just a faster version of the 29160 (note that there are problems with the on-board SCSI controllers too). After re-finding this (it's linked on my web site) I would *definitely* recommend getting a cheap IDE drive for your audio data.
