I had a look here for ALSA support http://www.alsa-project.org/alsa-doc...hnology#matrix
and I looked here for OSS support
I don't see anything starting with ess17 for either sound system. If it is really old, OSS is more likely to work, if you can figure out, or some one can tell you which driver.
There is a sound utility I used a while ago, called something like 'sndcfg' and it used to work with some older hardware.
Hopefully someone can tell you what driver will work.
