As crazy as it may seem, reducing the buffer may help. Also I noticed reduced CPU usage when I manually set the sample rate to my soundcard's native rate, 48000Hz.
Try changing your /etc/pulse/daemon.conf to reflect the following changes: ; default-sample-format = s16le default-sample-rate = 48000 ; default-sample-channels = 2 default-fragments = 8 default-fragment-size-msec = 10 This has eliminated stuttering for me with both ICH4 and ICH5 (AC'97) cards, but it may vary for other soundcards. Perhaps some AC'97 based cards have a small buffer, hence if the fragment number or fragment size is too high, it cannot fit in the buffer... -- Over-optimistic buffering in PulseAudio causes underruns (audible stuttering, pops) https://bugs.launchpad.net/bugs/190754 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
