Mic stopped working on Linux Mint
 
Hi,

I have a Toshiba Satellite, and I use Linux Mint Cinnamon.
Everything was fine until last Saturday, when my microphone stopped working. The only thing one can ear is noise, if I scream I can barely distinguish it in the background. I thought it was a problem of configuration due to an updated package, so I've updated the whole system from the v16 to v17, but without any improvement.

The configuration in alsamixer is the following one:

but, following an incredible number of threads in different forums, I've tried all the possible combinations/all the possible tools to change settings.
Any idea?
Thanks a lot in advance!!

Hi glacier.2000, Welcome to LQ. Please post the results of the following:

Code:

cat /proc/asound/card0/codec#* | grep Codec
Good luck. ;-)

Hi,

Thanks for your answer, here is the output of the command:

Code:

Codec: IDT 92HD99BXX
Codec: Intel PantherPoint HDMI

Have a nice day!

Maybe (I could be wrong) the mic somehow became muted-?

Open the terminal and type:
Code:

alsamixer
Raise up all of the columns, pcm, master and the mic too. If at the bottom of any of the columns you see this:
Code:

[mm]
That means it's muted. [oo] means unmuted.

yep, i can see from the screenshot it's muted.

glacier.2000 06-26-2014 12:46 AM

I've tried un-muting the microphone, but the only thing I can hear is a rustle (the strong white noise above mentioned). For other configurations in alsamixer (with MIC un-muted), I hear nothing.
I have read on the Internet that could be due to the fact that the system "hallucinates" and thinks it has a stereo microphone, therefore I should suppress one of the two channels (either left or right). I tried playing with all the possibilities for both MIC and the digital MIC, still no luck......
Any other suggestion?
Thanks a lot for your answers!!

Run this command that our Guru asked in post #2.
Code:

cat /proc/asound/card0/codec#* | grep Codec
Post the output in code tags so he can read through it and advise you.

@ztocrat: op did that already.
let's hope peacedog had something in mind when asking for it.

Some mic types require a small voltage. Some soundcards do not provide this voltage. It's sometimes referred to as plug-in power. When an electret mic doesn't have it explicitly it can have the behavior mentioned.

Or it could be something simple like things defaulting to muted on new installs. Although I wouldn't rule out hardware as most mics do not favor humidity or being wet or physical abuse. Cold dry outside to warm humid inside can cause condensation on parts. Or climate controlled office to hot and humid florida like outside.

It could be that the problem is hardware, although I have never moved or crashed into the microphone. I would, however, totally esclude something climate-related (no excessive cold/hot/humidity...)

Right, thanks-
I see in post #3 the output-

Sorry I don't know how to test for hardware failure associated with a sound card, except for Memtest but that's for testing the RAM-

Running the command: aplay -l should show what sound card you have.

Once you know what sound card it is maybe there will be something online or in the Linux Mint Forum in regard to behavior your having. I'm not sure if there are known issues with that particular card and Mint.

Like Shadow_7 said some don't have that voltage:-

Here's the output of aplay
Code:

**** Liste des Périphériques Matériels PLAYBACK ****
carte 0: PCH [HDA Intel PCH], périphérique 0: 92HD99BXX Analog [92HD99BXX Analog]
  Sous-périphériques: 1/1
  Sous-périphérique #0: subdevice #0
carte 0: PCH [HDA Intel PCH], périphérique 3: HDMI 0 [HDMI 0]
  Sous-périphériques: 1/1
  Sous-périphérique #0: subdevice #0

I will try this afternoon with a different live distro to see if this is really an hardware-related problem.
Thanks!!!

According to Google this is french-
Sous-périphériques: 1/1 means subdevices.
Carte means card and device3 is HDMI meaning High Definition Multimedia Interface.

You could research the HDA Intel PCH Analog card 95HD99Bxx online.
It could be a bug but I am not sure.

I'm thinking that if another distro has the same issue it could very well be a hardware problem.

Sometimes and in some cases if one is having performance or hardware issue's installing a higher version of the kernel can help solve that.

Maybe one of our members running Mint has experience with installing a newer kernel.
Sorry, I don't:-
