Audio problems in QNX 6.1

Hello.

We are using a CyberPro 5050 chips of IGS Technology.
This chips is SoundBlaster compatible.
It can set enable or disable in CMOS BIOS.
QNX6.1 and QNX6.0 both detects the SoundBlaster 16 - CT1745.

I’m runned Media Player in Multimedia folder and play a WAV format.
It work good at QNX6.0, but no sound at QNX6.1.

difference of driver:
QNX6.0: deva-sb
QNX6.1: io-audio -d sb

status of our system:

#ls /dev/snd
controlC0
mixerC0D0
pcmC0D0c
pcmC0D0p
pcmPreferredc
pcmPreferredp

#pci

PCI version = 2.10

Class = Display (VGA)
Vendor ID = 10eah, InterGraphics Systems
Device ID = 5000h, CyberPro 5000
PCI index = 0h
PCI Mem Address = fd000000h enabled
PCI Int Pin = INT A
Interrupt line = 11

Class = Network (Ethernet)
Vendor ID = 10ech, Realtek Semiconductor
Device ID = 8139h, RT8139A/B/C Fast Ethernet Adapter
PCI index = 0h
PCI IO Address = f800h enabled
PCI Mem Address = fedffc00h enabled
PCI Int Pin = INT A
Interrupt line = 10

Class = Mass Storage (IDE)
Vendor ID = 1078h, Cyrix Corporation
Device ID = 102h, Cx5530 IDE Controller
PCI index = 0h
PCI IO Address = fc00h enabled
PCI Int Pin = NC
Interrupt line = 0

Class = Multimedia (Audio)
Vendor ID = 1078h, Cyrix Corporation
Device ID = 103h, Cx5530 XpressAUDIO
PCI index = 0h
PCI Mem Address = fedff400h enabled
PCI Int Pin = NC
Interrupt line = 0

Class = Display (VGA)
Vendor ID = 1078h, Cyrix Corporation
Device ID = 104h, Cx5530 Video Controller
PCI index = 0h
PCI Mem Address = fedfe000h enabled
PCI Int Pin = NC
Interrupt line = 0

The above statement is the result of “ls”, “pci” command in shell.

I’m tried follow, but no sound at QNX6.1 …

#io-audio
#mount -T io-audio -oioport=220,ioport1=330,irq=5,dma=1,dma1=3
/lib/dll/deva-ctrl-sb

change ioport base address in CMOS BIOS, no sound…

set disable [Sound] section in CMOS BIOS, and run driver follow
#io-audio -d cyberpro5
or
#io-audio
#mount -T io-audio cyberpro5
, then not work driver…

Do you have any idea?
Please help me…
Thank.
