Same here. Installed corresponding alsa packages from intrepid, so skype and some other stuff now works under PA, but sound from some apps (like Skype, sdl-pulseaudio) is stuttering.
Kernel 2.6.24-17-generic helped a little or not at all, hard to tell exactly, but it doesn't solve the issue. I rarely have processors fully used, so this stuttering has nothing to do with system load - system may be even idle. I have a Dell Latitude D620 laptop, Intel HDA audio card (output from lspci): 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01) Subsystem: Dell Unknown device 01c2 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 20 Region 0: Memory at efebc000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> I changed the config in /etc/pulse/daemon.conf as suggested somewhere in the forums (probably written by Conn), by appending: default-fragments = 8 default-fragment-size-msec = 5 ...to this file. I am not sure what these values are, because buffer of 5 msec seems small to me, is the default even smaller? Anyway, this fixes my issues - pulseaudio is now very smooth. -- 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
