darrellg1,
Just to clarify things -
The ALSA driver for your card is "snd-opl3-sa2".
The OSS driver for your card is "opl3sa2" - it's native to DSL.
OSS configuration details here - http://damnsmalllinux.org/cgi-bin....;t=3056
You can use either driver, but obviously not both.  Also, it seems that some sound cards are detected at bootup and a driver loaded, but with the wrong settings.  In this case the driver should first be unloaded - "rmmod xxx" then reloaded with the correct settings.

spiff,
I understand that Linux has trouble detecting devices on the ISA bus, like these older sound cards.  There's a Linux utility for this purpose - isapnp, but I'm not sure if Linux distributions normally run it at bootup.
And in the case of ESS sound chips, the OSS and ALSA drivers actually have an option to disable isapnp, because it's known to be problematic.
Having said this, there's an ALSA utility - "alsaconf" which will successfully find and configure old cards.
