I've got a question that I always had just been a fact of life until
now.
I have an Aztech Sound Galaxy Pro 16 sound card. In order for it to
function, I have following in my kernel config file [line break
added]:
# Sound card
controller snd0
device sb0 at isa? port 0x220 irq 5 drq 1 vector sbintr
device opl0 at isa? port 0x388
# device mss0 at isa? port 0x530 conflicts irq 5 conflicts drq 1 \
conflicts vector adintr disabled
# device uart0 at isa? port 0x330 irq 5 vector "m6850intr"
options CONFIG_SBPRO
# options __SGNXPRO__
device joy0 at isa? port "IO_GAME"
pseudo-device speaker
Without the CONFIG_SBPRO, /dev/audio becomes a no-op. That's a minor
issue, but one that I probably should add to LINT.
My question is about sample rates. The first file I play (using
cp foo.au /dev/audio, with a proper header on foo.au according to
sox) sometimes comes out at the wrong sample rate. If I ^C it and
start again, the correct sample rate is emitted.
However, this only takes place with 8000 Hz 8-bit sounds. Others play
a distorted sound, clearly a different sample being interpreted as
8000 Hz 8-bit.
Should this be happening?
Best,
joelh
