hi,
I have problems getting audio to work on a Celeron system with 440MX chip
set and a AC97 codec (Sigmatel STAC9721T). The audio part of the 440MX
should be compatible to the 810 chipset (under Linux the system runs
without problems with the 810 driver).
Under QNX 6.2 the command
io-audio -d i8x0
results in the log with the following error messages:
Jan 01 16:56:26 1 7 0 Unable to detect PCI device (No such
device)
Jan 01 16:56:26 1 7 0 init_card: unable to init dll
deva-ctrl-i8x0.so
Jan 01 16:56:26 1 7 0 mount_card(): failed to initialize card
i8x0
pci -vv gives:

Under Linux the the driver for the 810 chipset can be used for the 440MX.
The problem here seems to be the different PCI-ID of the 440MX.
Is anyone able to give me a hint? I could patch the binary driver with the
440MX PCI ID, but this wouldn’t be the fine way…
Many thanks,
