The sbpro driver automatically chooses an unused DMA channel and IRQ line

for the device.

Note - The sbpro support for the AD1848 and compatibles uses one DMA channel

for both play and record; simultaneous play/record is not supported.

Turtle Beach Tropez Card With CS4231 Chip

• I/O Address:

0x530

The MWSS I/O address on the Turtle Beach

Tropez card is 0x530 at power-up. It can only be

changed by software after the system is booted,

and the Solaris operating environment does not

do that. Therefore, the Tropez card is only

supported at I/O address 0x530.

The sbpro driver automatically chooses an unused DMA channel and IRQ line

for the device.

Note - The Tropez card comes with a software utility for selecting the IRQ, DMA,

and MWSS compatibility I/O address settings used by the card. However, that utility

does not record those parameters in nonvolatile memory, but in a conﬁguration ﬁle

used by DOS to set the card’s conﬁguration at each reboot. This type of conﬁguration

ﬁle is not used by the Solaris software and does not affect the operation of the card

with the Solaris operating environment.

Known Problems and Limitations

Any Crystal Semiconductor CS4231-based devices supported by this driver are

programmed in AD1848-compatibility mode. This driver does not include support

for advanced CS4231 features; in particular, simultaneous play/record.

Some devices can detect that the IRQ is “in use” by another device in the system.

If this occurs, the driver prints an error message like the following, and you must

change the IRQ setting of either the audio device or the conﬂicting device.

sbpro: MWSS_AD184x IRQ 7 is ’in use.’

Some devices are not able to detect such a conﬂict. The driver will try to use the

card, but that will likely result in the system hanging when the card is ﬁrst used.

Thus, it is important to check that the IRQ that does not conﬂict with another

device.
