Thanks. Is the strange sound always there or only when playing sound
with certain programs?

Please try 3.2-rc7 from experimental, since it has some more Realtek
fixes.

Bug#654799: Cranking sound coming out of speakers with the new 3.1 kernel
 
Hello Jonathan,

The cracking sound starts right between bootup,
I would say when ALSA gets loaded into kernel ?
And then it persists there after I log into the system.

Kind regards,
Jan

Bug#654799: Cranking sound coming out of speakers with the new 3.1 kernel
 
Hello !

I tried booting into 3.2.0-rc7-686-pae, but the crunching sound
is still present, I am able to play music file properly, and
crunching is in the background, and also while not processing
any sounds, the crunching appears out of the speakers.

I tried also /etc/init.d/alsa reset
&
/etc/init.d/alsa restart

Kind regards,
Jan

Ok, thanks for testing. Please send a summary of this regression to
alsa-devel@alsa-project.org, cc-ing Takashi Iwai <tiwai@suse.de> and
either me or this bug log so we can track it.

Be sure to mention:

- steps to reproduce, what you expect versus what actually happens,
and how that indicates a bug

- which kernel versions you tried, and what happens with each

- alsa-info.sh output, as an attachment

- if you can make a recording of the strange sound available
somewhere online, that would be ideal

- whether you are able to bisect or test patches if needed

[1] may have more hints.

Thanks and good luck,
Jonathan

The sound is ok in kernel version "3.0.0-1-686-pae" but on all newer
versions there are sparkling/farting noises coming out of the speaker.
The noise is not very loud, its barely noticeable, but its repetative
and doesn't go away. And I think it happens while typing on the
keyboard and a bit later, then it dissapears for a few seconds,
or by the time that I type again.

> *- which kernel versions you tried, and what happens with each
I tried running alsa-info.sh as a "user".

I tried 3.0.0-1-686-pae here is the debug:

Because the noise is barely heard, I would need to find a good mic.
to be able to record it, but I could do that in the next bug submission.

> *- whether you are able to bisect or test patches if needed

I might try that, if there are any manuals around how to do it,
but my response might take some time.

3.2.0-rc7 alsa-info shows that the headphone jack is plugged, thus the
speaker is muted. It's natural that the noise goes away in this
state.

Apart from that, I see no obvious problem in 3.2.0 output.

Does the problem still happen when you disable "Auto-Mute Mode" mixer
enum?
% amixer -c0 set "Auto-Mute Mode" "Disabled"

Also, try to pass algin_buffer_size=0 option to snd-hda-intel.
I don't expect much that this will influence, but at least, it's a
difference between 3.0 and 3.2.

Bug#654799: Cranking sound coming out of speakers with the new 3.1 kernel
 
Hello !

The sound has been stable for the last days without noises,
after applying % amixer -c0 set "Auto-Mute Mode" "Disabled"

It seems this has solved it, until further notice.
You might want to keep the bug open for a while,
so I can check with all the kernels (it works with latest).

Kind regards,
Jan

OK, another question is whether the auto-mute feature works in hardware,
i.e. even when this mixer is set off, the hardware switches the
speaker upon plugging the headphone? If yes, we can simply remove
this switch and software feature from the driver.

Bug#654799: Cranking sound coming out of speakers with the new 3.1 kernel
 
Hello !

I can confirm that I have NO further sound errors in the following kernels:
ii linux-image-3.2.0-2-686-pae 3.2.9-1
ii linux-image-3.2.0-1-686-pae 3.2.6-1

The rest is still to be tested.

Kind regards,
Jan
