[SOLVED] Microphone problem with Dell Latitude 5410

[jur]

Checked BIOS, mic and camera are enabled.

Checked persistence, works.

There are no sound sockets on this laptop other than the normal headphone & mic sockets. The other functions are presumably accessible via the docking station (don't have one).

There are no returns on lspci or lsusb for camera, webcam or anything at all that looks familiar.

[jur]

Just booted into winxp again and checked the skype performance, the mic comes through crystal clear.

[aus9]

hi

your lsusb shows  0c45:6419 Microdia

this is your webcam

I will do some research later after I come back from work

[jur]

I looked into Microdia and it is most probably the SD card reader.

[aus9]

my apols

but the id is not there either way

http://www.linux-usb.org/usb.ids

2) I would still like to see the results of these commnd pls

cat /proc/asound/cards

cat /proc/asound/modules

3) lsmod may show your webcam module or not

I gather after re-reading your post that says

Last night I had the camera running when testing,

so your webcam must have module and should show up in alsamixer
so I am stumped at the moment.

4) Any chance of posting your laptop specs and a link to it motherboard manual?

[jur]

Wow aus9 you are going the extra mile and then some! 

The laptop is at work tonight so I will get back to this vexing problem tomorrow. I'll be sure to post every one of your requests carefully.

I load loadapp v4l-dvb-2.6.33.3-tinycore.tcz to enable the camera, that was it. I didn't have to do anything else; when I clicked on the skype 'test video' button, it came up immediately. I'm not sure if the mic is part of the webcam, and not even sure the little hole is a mic either because the knocking test does not result in anything coming from there, just near the left speaker. It could be that there are more than one mic because in winxp the little hole sure produces lots of output when knocking it. 

I'll see if I can find its specs...

[aus9]

hi

more requests now that I know how your module loads....as a part of the tcz package you load

Therefore after loading it.....THEN run alsamixer then see if you can see webcam

lsusb ....should work as well

cat .....cards command should work as well

----------I am very happy knowing this info as you can guess....it explains a lot



EDIT

oops I still want to see the output of your lsusb if webcam shows

and if you can see the webcam in alsamixer but are struggling with volumes show another image of it please

[jur]

The laptop is a Dell Latitude E5410. I downloaded its manual but the info is woefully inadequate. Except for the hole next to the camera - that is indicated as a mic.

The image I posted of alsamizer is the same with the webcam working, I remember checking, but I will check again. The only thing is, under the Capture section it sometimes shows a Digital slider, sometimes not. The image I posted does not show the digital slider but you will remember I asked what it is for. I am not sure what the conditions are, perhaps the Digital is enabled after I load the webcam package (which I load as part of skype). Another package I load with skype is libasound.

[jur]

Well I found some better specs elsewhere, googling for dell latitude e5140 specs. It mentions a digital microphone but not much else.

The knocking test which produced some effect when knocking on the front left but nothing anywhere else now sure is a mystery. Perhaps the sensitivity was so high that the mic channel was completely saturated. I will have to try again with the gains set much lower. Only problem is, I already did several tests like that. I will just have to repeat them.

[jur]

Further googling more specifically, revealed that this is a common problem with the Dell Latitude 5410.

hi

ok lets review so far

you have a laptop  Dell Latitude E5410..ok

Your codec was showing as
Codec: IDT 92HD81B1X5
Intel G45 DEVIBX
.....your image of chipset appears to be this G45 thingee

Now I have only just spotted you are reporting codec number 0 and 3
is there a 2?

thats why I wanted your output running thru grep.

Now if you look at your first link saying it solves for your laptop
Tim is saying the correct model=dell-s14
but that links to codec

as per
http://ompldr.org/vOHQ1OA/HD-Audio-Models.txt

2) the wiki shows you how to set your model assuming you are still happy with alsa but I am a little paranoid that I can not see an exact match for Tim's codec to your codec.

The explanation of jumping from HD81 to HD83 might be explained by having a more up-to-date Alsa lib and driver etc.

but I will wait to see what you do with your webcam alsamixer results which should show the chipset.

B) I see no value in the second post ...debian

c) The ubuntu person has your codec.....Codec: IDT 92HD81B1C5...well pretty close
and Tim's solution worked for this user so could be worth a shot

[jur]

my apols

but the id is not there either way

http://www.linux-usb.org/usb.ids

2) I would still like to see the results of these commnd pls

cat /proc/asound/cards

cat /proc/asound/modules

3) lsmod may show your webcam module or not

I gather after re-reading your post that says

Last night I had the camera running when testing,

so your webcam must have module and should show up in alsamixer
so I am stumped at the moment.

4) Any chance of posting your laptop specs and a link to it motherboard manual?

Here are the above requests, before loading the webcam tcz. (Alsamixer shows the digital slider):

hi

can you post the output of lsusb

I am still puzzled how you can have a webcam and it does not appear as a card in alsamixer
