Description of problem: This morning I upgraded to the latest Fedora kernel as usual (kernel-3.6.1-1.fc17.x86_64). After rebooting with the new kernel I noticed that Skype started having some background noise in every sound it tried to make. The normal Pulseaudio test passed fine. I reverted back to kernel 3.5.6-1 and the problem is gone. It's got to do something with the new kernel. Version-Release number of selected component (if applicable): kernel-3.6.1-1.fc17.x86_64 skype-4.0.0.8-fc16.i586 How reproducible: Always Steps to Reproduce: 1. Start Skype 2. Try to make a test call or test sound Actual results: Noise in Skype sounds Expected results: Clear Skype sounds Additional info:
I have the same problem when I run amarok. The problem disappears with the 3.5.6-1 kernel.
I have the same problem, on a Dell xps17. As above, The problem disappears with the 3.5.6-1 kernel.
Seems like the problem is indeed in pulseaudio. ALSA output works just fine, while PulseAudio output produces either no sound or highly distorted one. Here are the short list of versions of major components: kernel.x86_64 3.6.1-1.fc17 pulseaudio.x86_64 1.1-9.fc17 alsa-lib.x86_64 1.0.26-1.fc17
Mykola, I would argue that the problem is with the kernel as the Pulseaudio test passes fine and Pulseaudio didn't get upgraded the morning I installed the new kernel. Kolos
Kolos, Yes you are right from this point of view. But 3.6 has some core changes, which might make pulseaudio unhappy about. In addition: I have different two laptops Dell L502x and Dell L702x. The former produces no sound at all with PulseAudio output, while the later one works more or less OK (at least in Audacious and Chrome) and do have significant audio distortion in Skype only.
Mykola, Probably you have a better overview of the problem so if you think it's not the kernel that needs some changes rolled back, but rather Pulseaudio needs some changes to work properly with the new kernel, then fine, please change the component of this bug and assign it appropriately. Kolos
Rather interestingly with the latest kernel (3.6.2-4.fc17.x86_64) the problem disappeared for me. Has anyone fixed this? Kolos
For the ALC665 codec the problem is still there. Moreover, for the speakers the ALSA output is now disfunct, while headphones output works just fine.
The problem also appears to be fixed for me with 3.6.2-4.fc17.x86_64 on a Samsung Ultrabook Series 5.
Only kernel-3.7.0-0.rc1.git2.1.fc19.x86_64 makes Realtek ALC665 alive on Dell XPS L702x.
