microphone jack maybe broken, is it possible to isolate module?

vaquerito · 2010-04-06 16:45:33

Hi everyone,
yesterday while playing guitar with jack and rakarrak, sound stopped coming out from speakers.

I won't bother you with all possible tries I've done (alsa only,oss only,pulseaudio or not, jack or not), but I ended up even trying to boot off a live cd with *ehm* win7, to discard all possible configuration and driver issues, same result.

Soundcard is correctly recognized both in linux and win, I can start playing an .mp3 and the programs (vlc, mplayer, mpd) will show no errors, even the audio output gauge goes up and down as normal while playing, only no sound is heard both from speakers or headphone while inserted.

The only weird thing I see is both linux and win show a costant high input on microphone altough nothing is inserted, so I suspect a shortcircuit in one of the jack.

Is it possible to turn off microphone at a low level, as never loading its module? (BIOS has no option)

Thanks

As far as I know there is one module that handle all of the audio input/output for your card. The best thing you might be able to do is mute the microphone and turn down the volume.

I take it the you can't listen to anything in windows either?

vaquerito · 2010-04-06 18:06:20

yes, windows or linux same situation, nothing comes out of speaker.

Just to say, I try mplayer from console like

mplayer -ao alsa file.mp3

and no error, everything is smooth except sound.
Values in alsamixer are ok, all around 100%, tried even muting/unmuting digital out. But that's useless to say since I even tried in windows.

I really think something is wrong with electric parts since both in lin and win I see the input gauge at maximum with nothing attached.

I wonder if is there a way, even recompiling alsa to not give power to the microphone.

Tanks x your interest

If your sound card is a HD-Audio, you could try with hda-verb from AUR
Try with this command to switch front speakers on (as root):

hda-verb /dev/snd/hwC0D0 0x0b SET_PIN_WIDGET_CONTROL 0x40

Maybe you need to change the 0x0b (node) with the correct node in your soundcard see in cat /proc/asound/card0/codec#0

wow didn't know about hda-verb, tnx

I'm trying to get some knowledge on this, tried
http://mailman.alsa-project.org/piperma … 21460.html
http://mailman.alsa-project.org/piperma … 20407.html
http://digitizor.com/2009/10/22/fix-hea … top-linux/
with no luck so far.

While I experiment more, here is some extra data in case I'm missing something obvious,
laptop is a toshiba a300d, soundcard is ati sb conexant

Hi, I brought the laptop to a local technician and it seems microphone preamp or audio final is gone.

I need some hint.

I am thinking about buying a new soundcard that I can leave always inserted:

- USB or ExpressCard, which is better?
- is there some way to link it to the internal speaker?

Thanks
