Sound is still ticking/clicking after adding the following sysctl.conf entries (and rebooting of course;) hw.snd.latency_profile=0 hw.snd.latency=0 hw.snd.feeder_buffersize=16384 And additional info; after changing hw.snd.maxautovchans from 2 to 0 just to see if it had any effect on the skips and clicks: $ sysctl -a | grep snd hw.snd.latency_profile: 0 hw.snd.latency: 0 hw.snd.report_soft_formats: 1 hw.snd.compat_linux_mmap: 0 hw.snd.feeder_buffersize: 16384 hw.snd.feeder_rate_round: 25 hw.snd.feeder_rate_max: 2016000 hw.snd.feeder_rate_min: 1 hw.snd.verbose: 1 hw.snd.maxautovchans: 0 hw.snd.default_unit: 0 hw.snd.version: 2007061600/amd64 hw.snd.default_auto: 0 $ sysctl -a | grep pcm dev.pcm.0.%desc: VIA VT8251/8237A High Definition Audio Controller dev.pcm.0.%driver: pcm dev.pcm.0.%location: slot=1 function=0 handle=\_SB_.PCI0.P0P7.AZAL dev.pcm.0.%pnpinfo: vendor=0x1106 device=0x3288 subvendor=0x1043 subdevice=0x818f class=0x040300 dev.pcm.0.%parent: pci2 dev.pcm.0.play.vchans: 0 dev.pcm.0.rec.vchans: 0 dev.pcm.0.buffersize: 16384 dev.pcm.0.polling: 0 dev.pcm.0.polling_interval: 250 Regards, Byron C
