SBx00 Azalia ALC663 Working but MIC goes away

[Diego Jacobi <jacobidiego@xxxxxxxxx>]

Hi people.

I am having this problem for a long time ago, and i couldnt find the same on google, or a solution for it.

I also dont know the right way to write the question to google, because almost all are about problems that i dont have.

OpenSUSE 11.4 installed about 2 Months ago.

ASUS laptop n51tp

Athlon X2

ATI Mobility™ Radeon® HD 4650 

Audio System
Built-in Azalia compliant audio chip, with 3D effect & full duplex
Built-in speaker and microphone
Support Audio Jack Detect for Vista Basic Logo
Support Audio CODEC criteria for Vista Premium Logo

AUDIO WORKS with the 2 problems listed below.

ABSTRACT:

- Internal and external speaker both loud at the same time.

- MIC gets broke and an alsa restart is required.

PROBLEM 1:

If i start the laptop with no external headsets or speaker connected in front panel. Audio goes through internal speakers.

When i connect an external speaker or headsets (like to talk with skype), sound is duplicated.

It goes through both. Internal AND External. 

This is undesired behavior and the windows driver doesnt work that way. Internal goes mute when i connect an external.

Causes trouble when speaking with skype, as everyone can heard. Or earing a movie with a better equipment. Internal speaker are the poorest quality.

To only use externals i have to reset alsa with "rcalsasound restart" with externals plugged in.

IF i start the laptop with the headsets pluged in. The internal speakers will not work at all. Always in mute. Both the externals will work.

To use internals again i have to reset alsa with "rcalsasound restart" with nothing plugged in.

PROBLEM 2:

MIC works.

Internal MIC sucks. Nobody can ear me though skype.

External MIC works fine sometimes.

If i start the laptop with the MIC plugged in. It works. No problem.

If i start the laptop with the NO MIC plugged in. It doesnt works. I have to restart alsa.

If i do work with the laptop using different multimedia sources, it brokes.

Most of the time i get called by skype and the MIC is not working anymore. Then i have to close all programs, restart alsa and open skype again to be able to talk.

Thats the main reason to post here.

In the gnome's Audio-preferences dialog, the input tab, the level-bars :

- show as ghosts when it doesnt work.

- shows green changing, when it does works.

- shows as ghosts if no program is using the mic and changes to green if i start the recorder.

Restarting alsa requires closing Opera, Firefox, Skype, Emesene, Banshee, etc. to work or some of them will broke the MIC again. It also requires root privileges.

A broken headset also causes this behavior when i plugg it, and then MIC stops working until a reset.

MY GUESS about the problems:

as almost electronic engineer.

FOR PROBLEM 1:

The driver requires to detect check for high impedance at the front panel and mute the internal ones, and/or provide a way to mute them separately.

FOR PROBLEM 2:

A short-circuit problem may be happening in my front panel, and under some circumstances, like moving the cables, it causes some chipset failure over the MIC controller. The driver is not handling this error and it stays crashed until a reset.

However, it doesnt explains why seeing a video in flashplayer in opera may cause this too.

And it didnt happened on windows, but i dont have it anymore installed.

Also, i dont understand why AMD+ATI laptop uses Intel hda drivers. But i guess it has to do with ALC663 specs.

I will appreciate any help, and thanks to everyone reading this not-short post.

Cheers.

Diego
