[alsa-devel] Noise on snd-hda-intel
Plugging almost any headset into the front headset jacks on my machine results in noise in the headphones as well as in Skype conversations and/or recording. Said noise is, however not head in the regular speakers (except when playing back recordings, of course.

Ok, so you are using Ubuntu and a self-compiled Linux kernel. These are very important information so please mention it next time in the first place. The answers to the following question are probably useful too?
1. Is it a regression? Does this happen with the Linux kernel shipped by Ubuntu or did it happen with your self-compiled Linux kernels before? 2. If it also happens with the default Linux kernel shipped by Ubuntu the easiest way is to follow their instructions to solve sound related problems and report it to them using `ubuntu-bug audio` [1]. There are several developers working for(?) Ubuntu who will probably be able to help you really quickly.

I am sorry that I will not be able to help you any further because I do not know anything about the internals. I hope you will be able to fix your problem quickly.

Sorry forgot the quotes again. Will try to remember.

Duly noted.

Ad 1) I'm uncertain as to whether it is a regression. This is a new headset to replace my old one. The old one has done this on my desktop machine for ages, but not in my laptop. The new one does this on both desk- and laptop.
Ad 2) I'll try the official kernels and report there if it persists. Thank you.

That's perfectly ok - thank you for helping me this far and thank you for hoping :-)
Thanks,

Thank you for the suggestion, but it didn't help. At least not as I tried to mute or downplay it in alsamixer - should I try some obscure command to amixer?
Best regards,

Does the noise appear when you increase "Front Mic Boost" control from 0dB to 30 dB ?
arecord -v -f CD -Dhw:CARD=Intel | aplay -v -Dhw:CARD=Intel
Sorry for mailing in private. I'm used to lists that set Reply-to to the list :-$

arecord -v -f CD -Dhw:CARD=Intel | aplay -v -Dhw:CARD=Intel
Those commands give
aplay: main:660: audio open error: Device or resource busy
and thus no sound. I have played around with Front Mic Boost, though - it doesn't seem to alter the level of noise.

Which asus motherboard are you using ?
Do your computer chassis have a HD compliant front audio panel ?
I cannot find any situation which "Noise" appear in Front Panel HP only and does not on rear panel jacks for my ad1988a
I guess you have to check the front panel connector and Front Audio Panel
There are "click" when I change "Beep Playback Volume" and "pop" when unmute "Beep Playback Switch" in alsamixer on both HP jack and rear panel jacks of my ad1988
aplay -D pulse --period-time=500 48000Hz.wav
Playing one instance of aplay at minimum period time just cause CPU go up to 20% and the sound is still good
However sound is distorted after you play another instance of aplay at the same time
aplay -D pulse --period-time=500 44100Hz.wav

Is this a clean install of 11.4 or upgrade from previous version of ubuntu which use "default:2" and create "Digital Capture Volume" ?
since pulseaudio use "front:2" for playback and capture and this won't create "digital capture volume" control
Do you have any application which use the softvol plugin "PCM Playback Volume" ?
control.38 { iface MIXER name 'PCM Playback Volume' value.0 248 value.1 249 comment { access 'read write user' type INTEGER count 2 range '0 - 255' tlv '0000000100000008ffffec1400000014' dbmin -5100 dbmax 0 dbvalue.0 -140 dbvalue.1 -120 } } control.39 { iface MIXER name 'Digital Capture Volume' value.0 0 value.1 0 comment { access 'read write user' type INTEGER count 2 range '0 - 120' tlv '0000000100000008fffff44800000032' dbmin -3000 dbmax 3000 dbvalue.0 -3000 dbvalue.1 -3000 }

It is an upgrade.

How to remedy?

Not to my knowledge, but how do I check?

Thank you all for your help so far.
Currently I'm on a long-planned vacation until Saturday, but will take up troubleshooting when I get back.

Are you sure that it is noise ?
Just test Ubuntu 11.04 Live CD
HP has no sound when select Analog Headphone connector in gnome sound preference and HP has sound when select Analog Output as connector
I guess PA server cannot find "Headphone Playback Volume". since only "Headphone Playback Switch" exist in Ubuntu 11.04
The other strange thing is alsamixer can mute but unmute has no effect ,need to use gnome sound preference
