DESCRIPTION

     PCI AudioDrive chips (ES1938 and ES1946), e.g. the TerraTec 128i PCI
     card.

     playback functionality will be available.

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

     eso0: WDR timeout  The driver timed out waiting to send a command or
     writing to a controller register.

BUGS
