[alsa-devel] Conexant CX20561 - Microphone problems
Hello ALSA developers, I am having problems with the microphone on the following hardware this is on a Lenovo W500 laptop. Card: HDA Intel Chip: Conexant CX20561 (Hermosa) Here is the problems im noticing: 1) If I use ALSA 'default' with the microphone I get noise interference on output [high/low/high/low]. If I switch this to use the "ALSA Capture on HDA Intel [CONEXANT Analog] I get interference except it is the standard 60Hz electrical noise [steady noise] 2) Using the internal/external microphones gives an inconsistent volume. It also does not seem to work with the microphone cutting out so much. I need to adjust Digital + another microphone but it still drops capturing. Alsamixer shows: Digital/Docking Microphone/External Microphone/Internal Microphone Here is the module options I give to the sound driver: options snd-intel-hda enable_msi=1 power_save=10 power_save_controller=true model=laptop index=0 Assuming power saving/controller causes the microphone to cut out or not. 3) I'm now aware that this card has no pinouts for PCM capture https://bugzilla.redhat.com/show_bug.cgi?id=502293 Thanks for any help, Shawn.

Judging from the pin config, in your case, "Docking" seems controlling the external-mic volume. The "External Mic Volume" should be zero. Takashi

There is still problems with the volume sensitivity, but I will adjust to set ext mic to zero. Do we need a quirk for the Lenovo W500 then? Or that's a bug wrt to volume sensitivity and static interferences? Thanks, Shawn.

Looks so. Though, the SSID is identical with X200. I'm wondering whether X200 works fine as is or not...
Or that's a bug wrt to volume sensitivity and static interferences?
The mic boost volumes are missing in these quirks. You can adjust manually via hda-verb, e.g. hda-verb /dev/snd/hwC0D0 0x1d SET_AMP 0x7003 for the built-in mic, and hda-verb /dev/snd/hwC0D0 0x18 SET_AMP 0x7003 for the mic jack. Change the value between 0x7000 and 0x7004. Takashi

I set the mic boost volume quirk, that did adjust the loudness, so it doesn't seem to be cutting out anymore. So it looks like that problem is fixed with the quirk. Would you like me to provide you a sound recording indicating the interference I hear when using the microphone? Thanks, Shawn.

The interference is coming from: ALSA Capture on default (seems to be the digital device), yet HDA Intel [CONEXANT Analog] has no such interference. I suppose I could make an .asoundrc and force default to use the Analog device vs the digital one.
Thanks, Shawn.

So you have Lenovo X200 laptop, too? That's nice, so we can avoid the regression if we change the x200 quirk code. Takashi

1) If I use ALSA 'default' with the microphone I get noise interference on output [high/low/high/low].
If I switch this to use the "ALSA Capture on HDA Intel [CONEXANT Analog] I get interference except it is the standard 60Hz electrical noise [steady noise]
2) Using the internal/external microphones gives an inconsistent volume. It also does not seem to work with the microphone cutting out so much. I need to adjust Digital + another microphone but it still drops capturing.
Alsamixer shows: Digital/Docking Microphone/External Microphone/Internal Microphone
Here is the module options I give to the sound driver:
options snd-intel-hda enable_msi=1 power_save=10 power_save_controller=true model=laptop index=0
Assuming power saving/controller causes the microphone to cut out or not.
3) I'm now aware that this card has no pinouts for PCM capture https://bugzilla.redhat.com/show_bug.cgi?id=502293
Could you give alsa-info.sh output? Run with --no-upload option, and attach the generated file.
Here's the attached output,
Judging from the pin config, in your case, "Docking" seems controlling the external-mic volume. The "External Mic Volume" should be zero.
alsacontrol shows two 'Internal Mic' options and two 'Docking Mic' options, no External Mic option visible? Now using: 2.6.39-0.rc3.git2.0.fc16.x86_64 While this laptop can use a docking port, I have none, although the BIOS does give an option to enable docking ports, I guess those don't do anything unless you actually dock the laptop?

Hello ALSA developers,
I am having problems with the microphone on the following hardware this is on a Lenovo W500 laptop.
Card: HDA Intel Chip: Conexant CX20561 (Hermosa)
Here is the problems im noticing:

Just try model=hp. This corresponds to a model without the docking-station. Takashi
