Thread: Skippy sound in 9.04


yesterday did dist-upgrade of kubuntu 8.10 9.04 on laptop. went pretty good, have serious issue audio.

when playing (music or videos) sound choppy/skippy, i.e. given second (sometimes it's every second, it's 1 of 2-5) plays faster should (lasts less full second should). results in sound being sped , chopped fit in partial-second.

i've googled lot , followed tutorial on forum on setting pulseaudio (by removing old asound config files , installing pulseaudio tools) , didn't @ all.

issue tested songbird (my music player), audacity , various mplayer frontends. audacity seems handling after few initial choppy seconds, while songbird seems worst affected: music un-hearable.

issue affects video playback: youtube videos stuttery same way, video following audio (i.e. being choppy , seconds shorter are).

edit: adding myself pulse-rt group doesn't @ (and has borked kde system sounds welcome one)

same problem here. have fresh install of 9.04 on ext4 partition , sound terrible. skips every second.
before had 9.04 on ext3, upgraded 8.04 8.10 9.04 , didn't have problems sound @ all.
