There were several suggestions on this bug, but apparently none of them helped. I am clueless about the kernel internals, but the manifestations of this bug seem to be consistent with the hypothesis that there is something wrong with the radeon driver. It seems like something locks the system for long periods of time and the other time sensitive modules freak out. On my laptop the problem became even more pronounced when I swapped the 1440x900 LCD panel with a 1600x1200 one. A bigger display means more data is being moved around. It sounds to me like a chipset issue when large amounts of data are being transferred across the bus. KMS uses system memory more readily than UMS did which is likely why the issues shows up with KMS. I don't know of any other options to try in the driver. We don't have these problems with the same radeon chips is other systems. Unfortunately, I'm not a chipset expert so I'm not sure what sort of pci quirks, etc. to try. It could also be that the there is an issue in the sound or wifi driver which didn't show up as readily when there was less traffic on the bug.

Hi, Apologies if this is not strictly on topic regarding fixing this bug - what I'm curious to know is what the 'best case' workaround all of you are using to avoid this problem? I'm open to absolutely any distribution, desktop environment, etc. Just wondering what the best alternative many of you have found to avoid the conflict and maintain the most functionality. My best case options so far: Ubuntu 10.04 LTS where I don't remember noticing this problem, or even 12.04 in 2D if I could get my volume control buttons to work on my Thinkpad t60.

Just for the record I've tried Kubuntu 12.04.02 and the kwin_gles workaround does _not_ work for me unfortunately(T60 w/ X1400) .

Hi, I have been able to get around this bug on IBM T60/x1400 running Kubuntu 12.04, by using kwin_gles desktop manager instead of the default one (kwin). I had problems with sound slowing down and being very choppy when desktop effects were enabled, or when playing full-screen flash videos. I did not notice any problems with wifi. With kwin_gles I have absolutely no sound issues with desktop effects enabled. How to change the window manager see: http://weits.blogspot.cz/2012/02/kwin-gles-as-default-window-manager-in.html I'm not X expert, so please take the following lines as my humble opinion. I belive, that the workaround is caused by the fact, that kwin_gles uses EGL for rendering, while kwin uses GLX. So maybe this bug can be avoided on other distros and window managers by setting them to use EGL instead of GLX. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/571770 Title: Thread [hd-audio0] consuming excessive amounts of CPU, audio crackling To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/571770/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Øyvind Stegard, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If it remains an issue, could you please run the following command in the development release from a terminal, as it will automatically gather and attach updated debug information to this report: apport-collect -p linux 571770 If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-3.14-rc4 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed.

Hi, what is the state of this bug? I'm using the same hardware like Jason does (Thinkpad T60 with Radeon X1400 and Intel wireless) and running Ubuntu 11.04. Kernel Version is 2.6.38 and the problems with audio glitches and wireless drops are still there. From time to time the system isn't going to hibernate or doesn't wake up after. All this problems are gone without kms (radeon.modeset=0). But now the Problem has gotten even worse as without kms the radeon driver only works with software rendering and the unity desktop won't load. Same with gnome 3 running Debian unstable/experimental. If I can anything contribute to solve this bug, please let me know! Reading all the comments bisecting the kernel appears the most promising way to me. Anyone who wants to explain me how to do that?

[Bug 571770]
Taking opportunity of the fact that this ticket is coming back to life: this issue has still been accompanying over all mesa, X, ddx driver and kernel updates. I'm on 2.6.38 now, and sound is still stuttering. Its not a fix, but a little workaround. open terminal xrandr look whats your minimum resolution and tha name of the screen/output now edit the grub linux line with video=[OUTPUTNAME]-1:[MINIMALRES] for me its: video=LVDS-1:320x200 now reboot. KMS/VT will now have a res of 320x200, plymouth and X are normal. sound crickeling is gone (or I just can not notice it anymore) I can confirm that this works for me too; I set the VT framebuffer to 640x480, and the crackling is much better. In addition, my desktop feels significantly faster (I'm using KDE 4.6 with kwin compositing) --- in particular, switching desktops with many open, complex windows like firefox sitting is considerably better now. To the developers (and don't hesitate to beat me down if this is completely out of question): could it be that the issue is caused by too many transfers from system to video memory and the driver blocking interrupts while waiting for them to complete? As I suppose that changing the framebuffer resolution affects the VRAM layout, the impact of the above trick could be explained this way. This could also explain the fact this issue seems to predominantly affect users of laptops which have hardware relatively low on VRAM (64MB for my x1300 mobility). Speaking of which: the driver reports the following about my hardware: radeon :01:00.0: VRAM: 128M 0x - 0x07FF (64M used) radeon :01:00.0: GTT: 512M 0x0800 - 0x27FF [drm] Supports vblank timestamp caching Rev 1 (10.10.2010).

(In reply to comment #40) I never gave it much thought, but thinking about it, this seems suspicious to me as I am pretty sure that this device has only 64MB of VRAM. I'm using an X1400 here, with 128MB of vram. I'm not sure if that is helpful or not. Here's some extra info for the fire, and one that surprised me when I discovered it yesterday: there are a few apps that render fullscreen video that do not exhibit the stuttering at all. This is new behavior, previously ANY video would cause the stuttering when fullscreened. This change that I'm seeing may not be the same on your systems, but it's worth testing. A good example is the Hulu Desktop for Linux application, which streams high quality video fullscreen without any stutter. This uses the video card, the wifi connection, and the sound card at the same time, which is exactly the situation that causes problems for most people. The app specifies that it requires Flash 10.0.32 or higher, which suggests that it uses Flash for the video transport in some fashion. The application can be downloaded from http://www.hulu.com/labs/hulu-desktop-linux Also, on my system, switching into HTML5 video mode on Youtube (using Google Chrome) allows fullscreen 720p streaming without audio stutter. The same video played in standard Flash video mode (in Chrome or in Firefox) stutters heavily when maximized, in both 480p and 720p formats. In fact, any Flash-based web-embedded video stutters when maximized, on any site that I've tried (Vimeo, CBS, etc), including even Hulu's own web-based player. I'm not sure what the story is on this, it's confusing. Maybe on my particular hardware the radeon driver is able to cope differently with the particular video rendering method used by Hulu Desktop and the browser HTML5 video implementations. If the Hulu Desktop application is using Flash, it's doing it differently than viewing the same video on Hulu.com in a browser, because the web-embedded player stutters and the Hulu Desktop application doesn't, and both are (theoretically) streaming from the same source. I'm running very current versions of Mesa, Gallium and the radeon driver, so the particular combination of behaviors that I'm seeing may be a recent change. I also have a relatively fast system (Core 2 Duo with an SSD) and as always, system load seems to have a big impact on this issue appearing or not. So your results may not be the same as mine. possibly relevant information from glxinfo: direct rendering: Yes OpenGL vendor string: X.Org R300 Project OpenGL renderer string: Gallium 0.4 on ATI RV515 OpenGL version string: 2.1 Mesa 7.11-devel -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/571770 Title: Thread [hd-audio0] consuming excessive amounts of CPU, audio crackling To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/571770/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'd like the importance of this bug being corrected to 'major' because disabling KMS in fact means a major loss of functionality. I'm now on kernel 2.6.40 and sadly this heavy bug still is there. I skipped form Windows to Linux, mainly because the ATI Driver for the x1400 in my Thinkpad T60 (with iwl3945 od course) is crap.Now having tried many different distributions and kernels, i can confirm the bug still is there, and is making the notebook unusable. There's no 3D acceleration available at all on this GPU with KMS disabled. When playing a flash video it needs about 30 seconds fpr reaction if I clock some control with the mouse. Compiz or DirectX in Wine aren't working at all, and make the display crash. The GPU is wasting much energy and the notebook is running very hot, and overall just sluggish and not enjoyable in any fashion, I'd rather use my old Pentium M notebook, if it wasn't defective. Please consider creating a solution fot this problem, as there's no single alternative for many Notebook owners, of expecially good notebooks (Thinkpad, Dell and more).

How to most easily reproducce and verify the audio crackling: 1) Start gstreamer-properties and do a sound test. This produces a sound which very easily reveals crackling. 2) Fire up a web browser and watch a Youtube video in fullscreen with Flash plugin (low volume). 3) Listen to the sound of pop corn popping. -- Thread [hd-audio0] consuming excessive amounts of CPU, audio crackling https://bugs.launchpad.net/bugs/571770 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 571770] Re: Thread [hd-audio0] consuming excessive amounts of CPU, audio crackling
Mainline 2.6.34-rc6 has audio problems as well. While the radeon KMS performance is a *lot* better than in Lucid 2.6.32-kernel, graphical operations still sometimes cause audio skipping or slight crackling (for instance, fullscreen Flash video playback has a tendency to provoke the crackling). In addition to that there are audio/video sync issues caused by some ALSA updates (https://bugzilla.kernel.org/show_bug.cgi?id=15796), which makes it more difficult to know if the problems are really the same as in standard Lucid kernel. ** Bug watch added: Linux Kernel Bug Tracker #15796 http://bugzilla.kernel.org/show_bug.cgi?id=15796 -- Thread [hd-audio0] consuming excessive amounts of CPU, audio crackling https://bugs.launchpad.net/bugs/571770 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 571770] Re: Thread [hd-audio0] consuming excessive amounts of CPU during audio playback
I'm currently running snd-hda-intel module with options position_fix=1 bdl_pos_adj=0. This stops [hd-audio0] from showing up in top, but audio still crackles when scrolling in Firefox (for instance) after having used the desktop session for a while (more windows and apps open = more graphical resource usage). So in-kernel audio driver is badly affected by graphical operations, so much that it probably voids any effect of setting higher priority on pulseaudio user-space process... -- Thread [hd-audio0] consuming excessive amounts of CPU during audio playback https://bugs.launchpad.net/bugs/571770 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 571770] Re: Thread [hd-audio0] consuming excessive amounts of CPU during audio playback
Tried snd-hda-intel option enable_msi=1, since I figured it might be some IRQ issue. That didn't help. So I noticed CPU0 was handling all interrupts occuring on my system (via /proc/interrupts) for radeon and hda-intel modules. I altered the IRQ affinity for hda-intel, so it would be handled on the other CPU, but that did not help on the audio crackling either. So it seems I'm properly stuck for now, unless someone can come up with some other advice. Try newer kernel, perhaps ?
