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.

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.

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

[Jan Prunk]

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

[Jan Prunk]

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
