I suspect I am seeing the same problem, sound occasionally stutters with the loops being about half a second long. This happens irrespective of what application is producing the sound.
I am also using up to date Precise and this bug has existed since I installed. lspci | grep "Audio" : 00:1b.0 Audio device: Intel Corporation X79 series chipset High Definition Audio Controller (rev 05) 02:00.1 Audio device: NVIDIA Corporation GF110 High Definition Audio Controller (rev a1) but I am using the motherboard sound, didn't know I had any Nvidia audio stuff :/ Also, although the stuttering occurs more when I am compiling code or running a few programs, the system is far from heavily loaded and it is a fairly decent computer. I have read somewhere that there may be interactions between SSD's and the default disk scheduler, perhaps the audio stuttering is a symptom of another problem? (I do run off SSD's using the CFQ scheduler) I do sometimes see similar 'mini-lockups' in my browser that coincide with the audio stuttering. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1045771 Title: Underruns and stuttering Status in “pulseaudio” package in Ubuntu: Confirmed Bug description: When playing sound, be it in Clementine, in games via wine or in movies, I get stuttering.
