Microphone doesn't work


Hello,

I can't get the mic of my headset to work in Slackware 10.1. The headphone works, but the mic doesn't. I have the Audigy Player soundcard.

It's not a permission problem, as I did
Code:
chmod a+rw /dev/dsp* /dev/mix* /dev/min* /dev/seq*
The output of lsmod is
Code:
lars@desktop:~$ lsmod

have you set it to be 'captured' by the soundcard?

I suggest using alsamixer (type alsamixer at a terminal) as that seems to work consistently across a lot of soundcards. Tab moves between three 'views', playback, capture & combined (ie both at once) & you use the arrow keys, left & right to choose channels & up/down to raise/lower volumes. M toggles mute/unmute & spacebar toggles capture on/off. When capture is on it will show in red writing.

You need to be in the capture view, go to the microphone channel with the arrows, use M to unmute if necessary (when muted MM shows at the bottom) & use the spacebar to turn on the capture if necessary & raise the volume.

It is confusing at first because there are two voulme controls involved: playback volume controls what goes out but the capture volume controls what goes in. Its all about control I guess

Sorry if I have told you anything you know but this is a 1st stop check for me. I once had a very embarrasing recording session with a vocalist present & all was going wrong until 1/2 an hour later I found I hadn't selected the input to be captured! (Blush)

Let me know if this helps

Thanks for your reply. Unfortunately I can't turn on the capture for any channel. The spacebar doesn't change anything. In KMix the Input fields is also empty. Maybe it's a driver problem. Is there any additional module I have to load?

Hm, I just noticed something else...
Code:
lars@desktop:~$ amixer set Capture 10 cap
amixer: Unable to find simple control 'Capture',0

lars@desktop:~$ amixer set Mic cap
amixer: Unknown capture setup 'cap'..
That's really weird. I have no idea what the problem is, because the card seems to configured fine.

I must admit I am a bit stumped. Have you tried running alsaconf (as root) to see if that fixes it? Another thing to try may be to try something (say the alsamixer) as root. If it works as root then you know it is a permissions problem.

I have a machine with a Soundblaster platinum that uses the emu10k1 drivers same as your audigythat works fine. I am not on it now but when I am I will compare your lsmod to mine & see if there are any differences.

(BTW you are using alsa drivers that match your kernel. If you upgrade your kernel you need to update alsa as well.)

Post the output with
amixer scontrols
(or amixer -c 0 scontrols, 0 being the number of your card)

Thanks again. alsaconf as root was the first thing I did when configuring sound. There were no problems and the card was detected and configured properly. I also tried alsamixer as a normal user and as root. With both users it is the same problem. I can't toggle the views and it seems that no input channels are detected. The alsa packages match the kernel, because I didn't do any kernel upgrade. I still use the original 2.4.29. I'm really confused, because it seems that the permissions are set correctly and the driver works fine. If you could compare your lsmod to mine that would be great. Thanks for that.

BTW above is from a home grown live disc using slack 10.1 but with a 2.6.12 kernel (long story) so some of the differences will reflect that.

Thanks for posting your stuff. The amixer output is very similar. I only noticed that you have the following line which I'm missing:
Code:
Simple mixer control 'Capture',0
The lsmod output is pretty much the same. That's really weird. I can't figure out why I don't have any input channels.

just a Q.
do you have separate input/output plugs on that card,
or must they be configured as either output or input.

for example :i have a simple onboard soundchip and i can configure
the mic. jack as input or as one of the outputs for 5.1 sound.
of course, if i choose it as output, i cannot use it as input.

Hm, I think I don't have separate input/output plugs. At least I only have the normal 5 plugs with different colours. If I understand you right, the problem could be that everything is configured as output and I have to tell the mic jack that it is input? The problem is that I can't switch the view in alsamixer (spacebar on the mic channel doesn't change anything, it is always playback.

that could be because all is configured as output.
can you look in your cards documentation.
( or check their website )

for my mobo, i have to change some jumpers.
but your card is more advanced, so....see docs to be sure...

Ok, I downloaded their technical documentation, but unfortunately it doesn't say anything about linux. There were also no information about setting jumpers or stuff like that. Honestly I can't imagine that there is some hardware stuff to change, because the audigy player is such a popular soundcard (if not the most used soundcard at all) and I haven't read any problems concerning that. I'm afraid it must be something with my configuration.
