NAME

     eso -- ESS Technology Solo-1 PCI AudioDrive audio device driver

SYNOPSIS

     eso*   at pci? dev ? function ?
     audio* at audiobus?
     joy*   at eso?
     mpu*   at eso?
     opl*   at eso?

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

     eso0: can't map Audio 1 DMA into I/O space  PCI autoconfiguration did not map the first audio channel DMA controller into I/O space at a
     suitable address, and the driver was not able map it by itself.  In that case only playback functionality will be available.

     eso0: reset timeout  The device failed to acknowledge being reset.

     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.
