--- Comment #4 from [email protected] --- I think I have this problem as well. Pulseaudio will be working fine. When sounds play in rapid succession, or a program that emits sound while I already have a video or music playing, sound will turn into an amalgam of random screeches, blips, and crackles. It is not always immediate, and sometimes will go away when one of the sources of sound goes away, but not always. Currently running a slimmed down custom compilation of 3.7.5-1 on Arch linux. 3.7.5-1-custom2 #1 SMP PREEMPT Sat Feb 2 20:57:43 EST 2013 x86_64 GNU/Linux Audio controller: 00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04) Subsystem: Elitegroup Computer Systems Device 7c47 Flags: bus master, fast devsel, latency 0, IRQ 51 Memory at f7b10000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Capabilities: [100] Virtual Channel Capabilities: [130] Root Complex Link Kernel driver in use: snd_hda_intel I am able to get sound working again by either killing pulseaudio(which immediately respawns, or by opening up pavucontrol and changing the profile from "Analog Surround 5.1 + Analog Stereo Input" to 4.1 then back.(this may be reloading pulseaudio? idk) I've attached a recording of the static, in case that give any idea of what's going. Around 20s is the start of a new video, with a higher volume, resulting in louder garbled noise. I've also attached the output of pulseaudio -vvvvvv, started shortly before I forced the problem(I found that running a certain old game(widget workshop, if you must know) in wine happened to produce the issue fairly often), though it occurs plenty of times during day to day browsing/music listening/video watching. -- You are receiving this mail because: You are the QA Contact for the bug.
