Default ALSA dumping to term

hi guys. i just upgraded to kernel 2.6.25 & am now seeing a ton of
garbage from ALSA dumping to my terminal & syslog. whenever i play an mp3
from commandline or even switch songs within mocp, i get a lot of this
sort of thing:

ALSA sound/isa/cs423x/cs4231_lib.c:190: codec out - reg 0x10 = 0x80
ALSA sound/isa/cs423x/cs4231_lib.c:190: codec out - reg 0xf = 0xeb
ALSA sound/isa/cs423x/cs4231_lib.c:190: codec out - reg 0xe = 0xc
ALSA sound/isa/cs423x/cs4231_lib.c:190: codec out - reg 0xf = 0xeb
ALSA sound/isa/cs423x/cs4231_lib.c:190: codec out - reg 0xe = 0xc
ALSA sound/isa/cs423x/cs4231_lib.c:190: codec out - reg 0x9 = 0x9
ALSA sound/isa/cs423x/cs4231_lib.c:190: codec out - reg 0x9 = 0x8

seems to be normal output, not errors, but then there's no reason
it should be dumping to term OR to syslog. anyone else experiencing this
&/or know how to shush it? thanks.

Did you enable CONFIG_SND_DEBUG_DETECT?

hah, i sure did. damn. is there a way to disable it when loading a
module or is my only choice to recompile? thanks.

I don't know how to turn this off without a recompile. (I don't know too
much about DEBUG_DETECT.)

Maybe it is possible to recompile only the stuff in "sound" and keep the
rest.

It might be easier to get rid of the messages on the console if you
don't mind having them appear in the syslog. The alsa code uses a
dedicated function, snd_printdd(), do generate the DEBUG_DETECT
messages. You could try if the console output can be suppressed via the
normal /proc/sys/kernel/printk mechanism. (see the "kernel.printk"
comment in /etc/sysctl.conf)
