Description Midhun S Menon 2011-08-29 23:50:14 UTC
I use Linux Mint 11(KATYA)...I have pulseaudio 0.9.22-24-g67d18 installed. However, I cannot get my mic working. Only response is a periodic signal spike in the input channel. I can play songs/sounds. However, Mic won't work.

Also, when I give 'test speakers' option in the volume control, I don't get a response. 

PLease help

Mint is based on Ubuntu right? If so, then you've probably inherited the same retarded patch that Ubuntu shipped which broke the sound theme specifications and thus broke the Test Speakers UIs.

Please see: 
http://permalink.gmane.org/gmane.comp.audio.libcanberra.general/199
https://bugs.launchpad.net/ubuntu/+source/libcanberra/+bug/790608

If you have any contact with the Mint devs, please point out this stupid problem so they can fix it!

As for the mic, have you tried settng the stereo input channels out of phase (e.g. set one to e.g. 25% and one to 75%)? I've seen some mics that do this weird out of phase thing and cancel themselves out.... stupid I know but worth a shot.

Please also attach the output from "pacmd ls" to this bug.

Cheers

Thank you for the prompt reply...Here's the o/p you requested.
Comment 3 Colin Guthrie 2011-08-30 03:39:08 UTC
OK, so you *should* be using he Internal Mic according to that setup. Could you also supply the output of the alsa-info.sh script?

http://www.alsa-project.org/alsa-info.sh

(you generally download it and run it, then you can either attach the output or just post the link from the automatic upload that the script does).

Cheers!

Also, what app do you use to test the mic?

Thanks for the output, I'll take a look soon.

In the mean time would it be possible to answer the questions I've asked in my previous comments.

I'll restate them for clarity:

 1. As for the mic, have you tried settng the stereo input channels out of phase
(e.g. set one to e.g. 25% and one to 75%)?
 2. What app do you use to test the mic?

(I also asked if Linux Mint was Ubuntu based (which I'm pretty certain it is) and if you could liaise with its devs to let them know about the libcanberra issue. If/when you do this, can you please post a link to your mailing list archive or IRC log such that it's documented here too thanks :))

I have reported to the mint developers. What should I do to document it here.

And I have indeed tried the out of phase trial for speakers but to no avail.Still no response.

And for the mic, I just tried if some signal is received in the pavumeter...The Pulseaudio app........Have'nt tried anything else.
