Workaround is to disable timer based scheduling in /etc/pulse/default.pa AND setting default-fragments = 4 default-fragment-size-msec = 90 (or higher, lower still produces noise) in daemon.conf. Total hw buffer size is 371 ms (according to pulseaudio -vvv > pulse.log) ProblemType: Bug DistroRelease: Ubuntu 13.10 Package: alsa-base 1.0.25+dfsg-0ubuntu4 ProcVersionSignature: Ubuntu 3.11.0-15.22-generic 3.11.10 Uname: Linux 3.11.0-15-generic i686 ApportVersion: 2.12.5-0ubuntu2.1 Architecture: i386 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: martin 2432 F.... pulseaudio Date: Mon Dec 9 09:29:29 2013 InstallationDate: Installed on 2013-04-22 (230 days ago) InstallationMedia: Kubuntu 12.10 "Quantal Quetzal" - Release i386 (20121017.1) MarkForUpload: True PackageArchitecture: all SourcePackage: alsa-driver Symptom: audio Symptom_AlsaRecordingTest: ALSA recording test through plughw:SIS966 failed Symptom_Card: Internes Audio - HDA SIS966 Symptom_Jack: Mic, Internal Symptom_Type: Underruns, dropouts, or "crackling" sound Title: [N90SV, Realtek ALC663, Mic, Internal] Underruns, dropouts or crackling sound UpgradeStatus: Upgraded to saucy on 2013-10-18 (51 days ago) dmi.bios.date: 02/25/2010 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: 207 dmi.board.asset.tag: ATN12345678901234567 dmi.board.name: N90SV dmi.board.vendor: ASUS CORPORATION dmi.board.version: 1.0 dmi.chassis.type: 10 dmi.chassis.vendor: ASUSTeK Computer Inc. dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr207:bd02/25/2010:svnASUSTeKComputerInc.:pnN90SV:pvr1.0:rvnASUSCORPORATION:rnN90SV:rvr1.0:cvnASUSTeKComputerInc.:ct10:cvr: dmi.product.name: N90SV dmi.product.version: 1.0 dmi.sys.vendor: ASUSTeK Computer Inc. mtime.conffile..etc.modprobe.d.alsa.base.conf: 2013-12-08T17:23:33.527378 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1259070/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
