Erik Ackermann, 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 (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available (not the daily folder, but the one all the way at the bottom) 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-v3.12 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. Please let us know your results. Thank you for your understanding. ** Tags added: latest-bios-f11 needs-upstream-testing ** Description changed: On my CyberpowerPC Gamer Xtreme 1030 desktop running up-to-date Natty Narwhal 64bit on fresh install, there is a variable crackling overlaying the sound on my card when any sound is playing. It is invariable to the output, as looping the same clip does not cause crackling to loop. The output of sudo aplay -l is: card 0: M1010LT [M Audio Delta 1010LT], device 0: ICE1712 multi [ICE1712 multi] - Subdevices: 1/1 - Subdevice #0: subdevice #0 + Subdevices: 1/1 + Subdevice #0: subdevice #0 - Any idea's on what this is? Occurs with pulseaudio on or off (even with speaker-test), and only on my Delta 1010LT sound card. Jaunty livecd plays audio without crackles, while Natty livecd produces crackles. - --- + Any idea's on what this is?
