Internal microphone not working in Ubuntu 11.04 - HP Pavillion dv6000

[Walter Ribeiro]

[HP Pavilion dv6500 Notebook PC, Conexant CX20549 (Venice), Pink Mic, Front] No sound at all

After a clean install of Ubuntu 11.04, internal Mic doesn't work, on a HP Pavillion dv6000 notebook.
This problem did not happen in previous versions of Ubuntu.
Another problem that might be related is a speaker "pop" whenever audio driver is used by Totem, Audacity, Mozilla or other programs.

Can you help me?

I'm sorry to say that due to the amount of problems that version 11.04 have with my HP Pavilion, I decided to go back to version 10.10. I spent almost three months trying to solve these problems, but have not had much success. The community can not provide the needed support, so this is the only option to not give up free software.

[Walter Ribeiro (wribeirojr)]

I re-installed Ubuntu 11.04 from CD and for a few days internal mic worked fine.
At some moment, I don't know exactly when, it stoped working and "pop" sound began.

Same laptop HP Pavilion, same problem. I've installed fresh copy of Ubuntu 11.04 and mic stopped working (can't tell exacly straitgh way or after some time).... ITs a bit annoying, because Ubuntu pushes with a lot of new stuff, but fails to fix old bugs, which may one day turn up without any reason. Even bare Debian system has no problems with sound support!

[Walter Ribeiro (wribeirojr)]

Despite that I have had no support from the community about it, I discovered that it is not a bug of the microphone itself, but only a malfunction of the sound configuration form. The problem is that in the "Sound Preferences" window, the field "Conector" is not working. I got around this problem as follows: In a terminal window I typed "gnome-alsamixer". Then in the window that opens, I just check the "IntMic" box. I hope that it works for you too, good luck!

I have the same problem and I lost bevieve in open source option. Its like a pig with the lipstick on, once you get closer to this lady with the lipstick you realize its not a lady, but a big.... And what is the point going to this new unity field and leaving behind so many problems behind. This problem with sound car is very very old, and yet it still comes up... The reason for this is that bug's are being fixed unprofessionaly, with short time future perspective. Very disappointing.

[SDonatas (sdonatas)]

I have a solution....

1. Install "gamix" from ubuntu software center (it doesn't let to do that from terminal).
2. Launch program. Change from dropbox menu from external mic to internal mic and close apllication
3. Try skype or something else, it should work now

[Walter Ribeiro (wribeirojr)]

I have two bad news: the first is that the problem remains in Ubuntu 11.10. The second is that neither of the workaround suggested here has effect on Ubuntu 11.10. The option now is to open a terminal window and use the command "alsamixer". The internal microphone must be enabled in text mode.
Please developers team, this problem seem to be simple to solve, but the consequences may be big for common users.

Status changed to 'Confirmed' because the bug affects multiple users.
