In the meantime I solved the sound problem on the HP Pavilion dv7 - problems with levels of alsamixer being down (maybe Skype modified them) and some output settings wrong (guess they have been changed by accident).
Then I tried Ubuntu 10.10 beta from an USB stick and did not recognized the crackling sound any more (booted two times). So there is a good chance that the issue would be gone with 10.10. Would be cool if this could be fixed for 10.04 also because that workstation is being kept on LTS versions only. But for being sure would be cool if other people experiencing this could also try with a 10.10 live CD and confirm. -- [IDT 92HD75B3X5] Cracking noise on shutdown https://bugs.launchpad.net/bugs/578566 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
