Some systems with the OPTI chipset and a PAS will require you to

popping sounds, like a geiger counter, coming out of the PAS even when

@ -66,21 +95,17 @@ Please check your documentation (or verify with any provided DOS utilities
|

that may have come with your card) and set the IRQ or address fields

accordingly.
|

|

Also: Some systems with the OPTI chipset will require you to #define
|
||||
BROKEN_BUS_CLOCK in /sys/i386/sound/pas2_card.c. Symptoms are that

you will hear a lot of clicking and popping sounds, like a geiger counter,

Also: You can configure more then one card on a single DMA using
|
||||
ALLOW_CONFLICT_DMA.
|
||||
ALLOW_CONFLICT_DMA. This is useful for boards with more then one type of
|
||||
emulation.
|
||||
|
||||
|
||||
Probing problems: Since the SB16 uses the same IRQ and addresses for
|
||||
the different drivers, some of the snd dirvers will not be probed because
|
||||
the kernel thinks there is a conflict. This can be worked-around by
|
||||
setting the ALLOW_CONFLICT_IOADDR or ALLOW_CONFLICT_IRQ options.
|
||||
|
||||
Warning: Setting the ALLOW_* options will will bypass checks for ALL drivers,
|
||||
so be careful when you use them!
