[Bug 879790] Re: Sound doesn't play properly after upgrade from 11.04->11.10
Yes that workaround also worked on SuSe 11.4. This is not a problem just with Ubuntu, having tried a few current distro's in an attempt to find one which works I can say that they all have the same issue in varying degrees, at least that's my experience. Interestingly I have also come across a few references to similar problems in XP. My gut feel is that it's an ACPI / interrupt mapping problem but really don't know enough to prove / investigate it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/879790 Title: Sound doesn't play properly after upgrade from 11.04->11.10 To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/879790/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 879790] Re: Sound doesn't play properly after upgrade from 11.04->11.10
O.K done something I should have done a while ago, had a look on the lenovo forums and then on to Intel. What I have found makes me sad and angry at the same time. This is a hardware problem at a multiplicity of levels which neither Lenovo or Intel are going to resolve anytime soon if ever. Ref:- http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/Audio-stutter-on-T61p/td-p/43413 and if you read through this thread it will eventually take you to this... http://communities.intel.com/thread/6021?start=90&tstart=0 Both the WiFi and Network drivers in current kernels come from Intel. A bit ironic that the Linux community has of late taken to applauding HW manufacturers for providing Linux drivers, not much point if what they provide is c**p. I guess that to resolve this would need somebody upstream in the kernel / driver development areas to take a look. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/879790 Title: Sound doesn't play properly after upgrade from 11.04->11.10 To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/879790/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 879790] Re: Sound doesn't play properly after upgrade from 11.04->11.10
Read the contents of the links I posted, when you analyses all that has been said on those forums the problem is down to Deferred Procedural Calls principally it would appear from Network stuff or video stuff, Intel admit that they have a problem with some of their drivers, and that is demonstrated in other ways the iwl3945 driver is at least on my machine forever having to re-start the hardware or reload the driver, it's probably not coincidence that in my case currently I appear to only have a problem coming out of suspend / hibernate some wifi cards are well know for having problems with power saving modes. My take on it from much reading various forums is that this problem seems to happen on machines with both Nvidea and ATI (I have ATI) and on machines running ALL flavours of operating systems, that takes you down to BIOS /EC /ACPI code, just because you disable / remove the operating system driver that doesn't mean that the device is inactive at a BIOS / ACPI code level. I feel pretty sure that if I could get the sound interrupts up to a priority level above that of video / network /keyboard there wouldn't be a problem (at least with audio). I use to know how to do that but PCI & ACPI have turned what was a simple subject into a black art which I no longer understand. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/879790 Title: Sound doesn't play properly after upgrade from 11.04->11.10 To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/879790/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 879790] Re: Sound doesn't play properly after upgrade from 11.04->11.10
Ah! yes but is it still good after a "suspend" or hibernation? Under Ubuntu my sound is fine until I do a suspend, when it comes back it's bad. Interestingly and Apropos another post re under Gnome Shell I have discovered that running Gnome on SuSe 11.4 sound appears to be fine both before and after suspend, under KDE it is even worse than Ubuntu. and now my mouse has gone to sleep ! *&$.

Re: [Bug 879790] Re: Sound doesn't play properly after upgrade from 11.04->11.10, also affects 12.04
Seemed to have been able to clear it on mine by flashing the BIOS with the latest available. This on a T61 with ATI graphics running SuSe 11.4. Gnome and Banshee run sound just fine now. tday On Fri, 2013-04-26 at 04:33 +, Michael-fulthorp wrote: > I came across what I believe to be this issue: When playing a file in > Rhythmbox I would get crackly audio when scrolling in Chromium (was > getting crackly audio while using other applications too, but scrolling > in Chromium was the most reliable way to reproduce it).

[Bug 879790] Re: Sound doesn't play properly after upgrade from 11.04->11.10
I also have this problem on a T60, not much I can add to what has been said. It isn't just Ubuntu, I came to Ubuntu from Suse 11.4 which has the same problem also Ubuntu 11.04 is no different to 11.10 One thing I have noticed is that in my case sound appears to be good at least for ten minutes or so until the computer goes into a suspend or hibernate state on coming out sound is broken and choppy distinctly worse with any screen activity. One solution I have read suggests re-starting alsa after a suspend so far havn't managed to do this "alsa force-unload" fails. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/879790 Title: Sound doesn't play properly after upgrade from 11.04->11.10 To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/879790/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
