https://bugzilla.novell.com/show_bug.cgi?id=732096 https://bugzilla.novell.com/show_bug.cgi?id=732096#c0 Summary: Microphone input hissing background Classification: openSUSE Product: openSUSE 12.1 Version: Final Platform: x86-64 OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Sound AssignedTo: tiwai@suse.com ReportedBy: kristjan.ugrin@gmail.com QAContact: qa@suse.de Found By: --- Blocker: --- Created an attachment (id=463480) --> (http://bugzilla.novell.com/attachment.cgi?id=463480) 12.1 related files User-Agent: Opera/9.80 (X11; Linux x86_64; U; en-GB) Presto/2.10.229 Version/11.60 When capturing from microphone I get a strange hissing background noise, which I cannot cancel out no matter what switches I touch. Today again I tested with live cd - 11.4 and in works well - no hissing, so it must be only 12.1 related. I'm attaching lspci, uname, lsmod and screen captures of mixer levels from both - 12.1 and working 11.4. NOTE: pulseaudio is disabled in both! Reproducible: Always Steps to Reproduce: 1. must have Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) 2. Open e.g. audacity 3. record mic input Actual Results: There is hissing sound in backgroud - it's annoying when talking with someone via voip. Expected Results: Normal audio input without interference. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Get hda-verb program from OBS home:tiwai repo, and run like: hda-verb /dev/snd/hwC0D0 0x1e SET_PIN_WID 0x20 Does this reduce the hiss noise? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I've tested with 2 sequential skype test calls, one before and one after issuing above command. There was less "chirping" noise. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

"rpm -ivh --force --nodeps kernel-xxx.rpm" should work for multiple kernels. Then test the basic recording via: arecord -Dplughw -fdat -vv foo.wav on both 11.4 and 12.1 kernels. (Run hda-verb command above for 12.1 kernel before testing.) Do you still hear the difference? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I've also set in skype to explicitely use the microphone input and I cannot hear the hissing anymore in that application, it is the same as recorded. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=732096 https://bugzilla.novell.com/show_bug.cgi?id=732096#c8 --- Comment #8 from Takashi Iwai 2012-01-27 14:34:16 UTC --- OK, what about the hda-verb pin setup? If you pass 0x21 instead of 0x20, does it make sound worse? The difference is the bias voltage. 0x21 means the vref-50 and it's usually a better choice for the mic input jack. Meanwhile, for a line-in jack, 0x20 may suit better. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

To me the bug is resolved, will include the regulating voltage into a startup script.
