DESCRIPTION
     The eso device driver supports sound cards based on ESS Technology Solo-1
     PCI AudioDrive chips (ES1938 and ES1946), e.g. the TerraTec 128i PCI
     card.

DIAGNOSTICS

     map the first audio channel DMA controller into I/O space at a suitable

     playback functionality will be available.

     eso0: RDR timeout  The driver timed out reading data from a controller
     register.
