O.k., so some more testing. Here's what I did: $ pulseaudio -k && LANG=C pulseaudio -vvv > ~/pulseverbose.log 2>&1 $ parecord -r pulsetest.wav record sample in audacity and export to "test-audacity.wav" $ pulseaudio -k && LANG=C pulseaudio -vvv > ~/arecord.log 2>&1 arecord -f cd -d 5 test.wav pulseaudio -k && LANG=C pulseaudio -vvv > ~/audacity.log 2>&1 start audacity and record with input hw:0,0 (not pulse)
then converted the output wav files to ogg for size reasons. Find all the files attached. Funnily, parecord gives better output than arecord, audacity using pulse input is unbearable, but using alsa hw0:0 seems fine again... My final aim is to make skype working. Right now I can't talk to anybody, they just won't understand me because of all the noise... ** Attachment added: "arecord.log" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1259070/+attachment/3927494/+files/arecord.log -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1259070 Title: N90SV, Realtek ALC663, Mic, Internal Underruns, dropouts or crackling sound Status in “alsa-driver” package in Ubuntu: Incomplete Bug description: Recording directly with arecord works, but using pulseaudio has crackling noise. 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
