clicking noise with Sigmatel STAC9202

clicking noise with Sigmatel STAC9202

[Christian Steffen]

Hello to all subscribers,


I'm new to this list and will start directly with my problem:

I'm running some ubuntu linux on a device called "o2 Joggler", which is a
digital picture frame with touchscreen control.
Its chipsets are from intel, the cpu is an intel atom, and the other
hardware devices are controlled by an Intel System Controller Hub "Poulsbo".

I'm running kernel 2.6.30 and the newest alsa version 1.0.20.

This is lscpi output:
>>00:1b.0 Audio Device: Intel Corporation System Controller Hub (SCH
Poulsbo) HD Audio Controller (rev 07)

cat proc/asound/cards:
>>0 [MID     ]: HDA-Intel - HDA Intel MID
>>              HDA Intel MID at 0xd01c000 irq 16

The Codec is a
>>Sigmatel STAC9202


My problem is, that sound is working, but has constant clicking noise in the
background, also if the sound is completely muted.
First I thought this sound would come from some hdd or whatever, but the
device has no mechanical parts. But this is what it sounds like - Irregular
clicking noise.

This noise immediately starts during boot up as soon as the module is loaded
and before X11 has started.
I already tried options like "position_fix=1 or 2" and different
"model="-options with no success.
"position_fix" didn't do anything at all and different model-options have
muted the device completely.


Has someone any idea to get this working?
The device comes with an own (hardly) closed linux which runs a 2.6.24
kernel - here sound is working with no problems at all.

If you need further info, let me know.


Thanks in advance, best!
Christian

Is the older kernel as is even with the same user-space stuff?
If so, run alsa-info.sh (with --no-upload option) and save the
content.  Then run with the newer kernel and save the content.  Attach
both files to compare.


thanks,

Takashi

Please run it with --no-upload on both kernels, and attach both
generated files.

Well, then at least, the contents of /proc/asound/card0/codec#*,
/sys/class/sound/hwC0D*/*_pin_configs files (if present), and the file
generated via "alsactl -f somefile store".  These are the most
important information.

Here I send the two also-info files as attachments.

Initial problem was:
Under kernel 2.6.30, Sound is working, but has constant clicking noise in
the background, also if the sound is completely muted.
First I thought this sound would come from some hdd or whatever, but the
device has no mechanical parts. But this is what it sounds like - Irregular
clicking noise.

This noise immediately starts during boot up as soon as the module is loaded
and before X11 has started.
I already tried options like "position_fix=1 or 2" and different
"model="-options with no success.
"position_fix" didn't do anything at all and different model-options have
muted the device completely.

Kernel 2.6.24 with the same files has no issues.
