Bug Description
i can reproduce this bug on my system
i got lucid with fresh updates and linux 2.6.33
i audio is totally broken after changing volume, i can hear just
ringing, cracking....if it fails.
my syslog has no info, so i don't know how i can support you with more data

on startup sound is fine, so starting planing music is ok, but if i tune the volume or jump forward, then just crap comes out of my boxes....
if i restart the track it is still there, but if i do nothing an wait half a minute sound is ok again
strange problem, but it makes sound unuseable

The above line doesn't make any sense. The only thing you needed to add was:
options snd-hda-intel position_fix=1
LPIB is the method we're trying to test. What is the position_fix=2 doing there? (It makes the first value useless.)

Please use Lucid's kernel, not a mainline one, to reproduce the symptom.
now the "sound" sounds minimal different, it comes now with a higher chance to fail.
comes with totem and audacious and with different mp3s,
but it is not present over the time, after some minutes it is ok again, and if i jump in the track it fails again.
but if i just play the track and not using "jump" oder "volume up/down" it never fails....
and i checked the cables!!!;)

woooow i solved the issue, it was: a bug in config/gnome-gui:
i can now reproduce the config to the bug;)
steps:
open audio config from sound-icon in tool-area
hardware
choose input
goto input and go over 100% to max per ex. (and choose line in)
choose output
sound is now present, but after jumping in tracks, it fails
i hope you can reproduce it on your system.
so you can write a fix AND/OR write a documentation
for q&a i will follow this bug
ok, i was too fast, problem was still there
but i'am now testing alsa-backport-
i will give feedback later

now i have:

Linux infrared 2.6.32-19-generic #28-Ubuntu SMP Thu Apr 1 10:39:41 UTC 2010 x86_64 GNU/Linux
with alsa driver from the ppa
now the problem occurs not every time i jump in a track, but it is still there.
it comes from jumping and if i change the volume of the application
strange: if sound fails, i just have to wait 5 seconds, and the same track with the same player is ok again
> strange: if sound fails, i just have to wait 5 seconds, and the same track with the same player is ok again
it is ok again if that happens:

Are you still using the position_fix=1 quirk?
>Are you still using the position_fix=1 quirk?
without the quirk i have results described in the last massage
with the quirk i got:
jumping in a track now works
change volume in totem now works
BUT: changing volume of the output stream in pulseaudio (pulseaudio volume control) has a problem:
there are some "hot spots" where the sound is ok (85%,...), but the other values are not use able, because the sound becomes noise
the setup with die quirk is much better than without...
additionally i get:
Apr 5 12:33:08 infrared pulseaudio[1484]: ratelimit.c: 2916 events suppressed
every 5 seconds, but without any sound problems...

Just to clarify, using position_fix=1 is necessary to have tolerable playback *and* capture?
position_fix=1 is necessary to have tolerable playback!
i never ever had i microphone and i never captured something.
the problem is now in the output stream volume control of pulseaudio.
the gnome applet for volume is now unusable...see:

Please test capture, else I can't send the fix upstream. Also, your description of the volume control makes it seem as if position_fix=1 doesn't actually help...

that fixes ALL problems no need for other config/options or newer packages
thanks for helping!
here i am again, sorry for log delay.
i have to revert my last post, which says that the problem is fixed.
>> IT IS NOT. <<
i can reproduce it on my two pcs, samsung-nc10 and shuttle, both with:
$ cat /proc/asound/
Codec: Realtek ALC662 rev1
i got the latest patches and alsa from the audio-dev-team
fix_position and/or forcing model=xxx don't help!!
so i found: https:/
in my opinion *IT IS* the same problem
i think it it not a configuration problem.
it seems to be a problem with the alsa-diver for my crappy on-board-
it fails if i *seek the volume* OR *jump in a track*, that must be a problem with the sound-buffer-
a saw the talk with lennard pöttering on linux audo conference and he said that exactly this is hard to code.
i have this stuff in my syslog:

Keep in mind that the syntax is position_fix=1, not fix_position=1 or fix_position.
If position_fix=1 helps, then please make sure you've filed a separate bug [if you aren't the original reporter of this bug report].

I do _not_ have 'watchdog' in my /etc/default/grub.
As I said in #29, position_fix=1 does _not_ fix the issue for me. Let me know if you need more info from me.

position_fix=1 fixes the problem!

i will test it on my netbook (nc10) and will report the results with lspci
my samsung-nc10 do not need position_fix=1, so it is enough to clean /etc/default/grub and remove nmi_watchdog=1.
so, for me, this is completely fixed.

The abovementioned fix is now upstream in kernel 2.6.32.16.
| Steve Conklin (sconklin) wrote : | #41 |
SRU Justification
Impact: The upstream process for stable tree updates is quite similar in scope to the Ubuntu SRU process, e.g., each patch has to demonstrably fix a bug, and each patch is vetted by upstream by originating either directly from Linus' tree or in a minimally backported form of that patch.
The 2.6.32.21 upstream stable patch set is now available and contains fixes for this problem. It should be included in the Ubuntu kernel as well.

The popping/skipping has returned.
Note my comment #29 -- "position_fix=1" did not fix the issue then, so I'm not sure if this fix is even relevant to my case. If it is not, apologies.
My alsa-info is attached.

...hm cross-posting via email may or may not work. Manually adding and hoping LP does not think otherwise later...
And no, I am not sure the popping/skipping returning is valid when porition_fix=1 did not help.
This is updating a set of bugs, so things said may or may not be exactly matching the bug report itself.
There is a set of bug reports which, reading feedback from reporters, do not seem to be fixed by the patches which were thought to fix them. All of these patches are part of some upstream stable release, so if a real fix is found, it
should be submitted there as well.
Quickly reading over the reports they all seem to be positional quirk fixes in ALSA. In one of the reports David had a quick look and had the suspicion that the code path of activating the fix may not be hit at all.
So while not fixing the bug all patches are not causing things to regress. Due to automatic processes, these bugs will get changed by a bot to fixed when the proposed kernel moves to updates and the bugs need to be re-opened then.
David, Daniel, maybe you can have a look at the test feedback and find out why the quirks have no effect?
Thanks,
Stefan
