Description of problem:
just after resetting the hardware on the boot loader, i start to hear
fixed unchangable continous sound (like when you turn your mic infront
of the speakers) .
alsactl restore doesn't work . 
all alsamixer's values remain 100% .

i'm using:
Linux harmony 2.6.9-1.667 #1 Tue Nov 2 14:41:25 EST 2004 i686 i686
i386 GNU/Linux

with alsa-lib 1.0.6-6

### Sound
# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-sb16
# module options should go here
# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0

Version-Release number of selected component (if applicable):
alsa-lib 1.0.6-6

How reproducible:

Steps to Reproduce:
1.boot the computer

Additional info:

i'm not sure but i think it happend just after updating the alsa libs

Is there a particular input or output when muted that makes it go away?
Comment 2 Nadav Kavalerchik 2004-12-11 03:16:36 EST
muting the device (via KDE's mixer) doesn't change a thing. 
and i think i found a discussion thread describing the problem: 
here is part of my lsmod:

snd                    54053  15 
soundcore               9889  1 snd 
here is  (part of) what kudzu found: 
class: AUDIO 
bus: ISAPNP 
detached: 0 
driver: snd-sb16 
desc: "Creative SB16 PnP - CTL0031" 
deviceId: CTL0031 
pdeviceId: CTL0025 
class: UNSPEC 
bus: ISAPNP 
detached: 0 
driver: ns558 
desc: "Creative SB16 PnP - CTL7001" 
deviceId: CTL7001 
pdeviceId: CTL0025 
compat: PNPb02f 
class: UNSPEC 
bus: ISAPNP 
detached: 0 
driver: unknown 
desc: "Creative SB16 PnP - PNPffff" 
deviceId: PNPffff 
pdeviceId: CTL0025 
class: UNSPEC 
bus: ISAPNP 
detached: 0 
driver: unknown 
desc: "Creative SB16 PnP - PNPffff" 
deviceId: PNPffff 
pdeviceId: CTL0025 
what's also interesting is that the internal modem (which is isapnp) is not working 
too ! 
here is what kudzu found about it: 
class: UNSPEC 
bus: ISAPNP 
detached: 0 
driver: unknown 
desc: "Texas Instruments Inc. TUT 33.6 FAX Internal - TEX0002" 
deviceId: TEX0002 
pdeviceId: TEX0011 
actually i think it's a problem with isapnp detecting the devices on board. 
Comment 3 Bill Nottingham 2004-12-13 20:17:44 EST
If it's loaded, it's detected fine. Assigning to the kernel, seems
like a driver issue.
Comment 4 Nadav Kavalerchik 2004-12-14 10:48:27 EST
I'm using 2.6.9-1.667 for a long time and it append after updating a bunch of RPMs 
with the up2date. ( so i don't think it's a kernel module problem ) 
unfortunately i don't really know which RPM update caused it. 
a little bit more info... 
when I'm passing acpi=off to the kernel while booting the "continues sound" from 
the speakers is not generated. ( interesting ! ) i've compaired: IRQs IO-ports and 
more data from boot to boot and i don't c any difference ,even when disabling the 
acpi ( daemon too ) 
Comment 5 Nadav Kavalerchik 2004-12-17 03:53:45 EST
i don't know way but today i logged into my user using xfce4(rc1) and
found out that the sound works just fine :-)

i think it was a KDE bug !!! 

so i'm closing this one

thanks for all you help
nadav :-)
