Mic does not work


Hi guys,

I have installed Slackware 10.2 with the 2.6.13 kernel from testing on the second CD.

Everything works ok ... excepth that I cannot use my mic in skype.

I have an Intel D845GLAD motherboard with on-board sound and use the snd-intel alsa driver.

I have sound output in all my apps. Even in skype I can hear the lady on the Echo123 testing service but when she asks me to record my voice and then plays it back I cant hear anything.

I can play sounds in multiple apps simulataneously and everything.

Would anyone be able to help me sort tis out.

Thnx in advance.

chgrp audio /dev/dsp
chgrp audio /dev/dsp*
or

chmod 777 /dev/dsp
or
chmod 666 /dev/dsp !!!! DANGEROUS for Security

type
Code:
alsamixer -V all
this will show all controls, go to mic capture or similar

when you are done type
Code:
alsactl store
you should be all set

be root when you do it

Once AGAIN,as far as I understand Linux, there is no such device as /dev/mixer. Linux, however defines mike as /dev/dsp
chmod 777 /dev/dsp
or
chmod 666 /dev/dsp

I was reading some more about this and tried the following :
---------------------------------------------------------------------------
root@darkstar:/home/neil# arecord -d 10 -f cd -t wav -D copy foobar.wav
ALSA lib pcm.c:2090snd_pcm_open_noupdate) Unknown PCM copy
arecord: main:533: audio open error: No such file or directory
root@darkstar:/home/neil# arecord -d 10 -f cd -t wav foobar.wav
Recording WAVE 'foobar.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
root@darkstar:/home/neil# play foobar.wav
----------------------------------------------------------------------

Still no luck playing back the file or in skype

Hey guys,

If anyone is reading this .... I know what the problem was .....

I shall now kill myself .....

I had installed the 2.6 kernel with the alsa driver as mentioned above.

But I did not remove the old driver for the 2.4 kernel.

Skype now woks beautifully as root

So I guess its just a permission problem for a user which I should be able to sort out by following the steps above.

Again ... totally sorry for all the trouble caused ....

SlackerLX, KingOfDreams & kodon ..... THANK U VERY MUCH for all the support.

Rgds,

madmax

Lightbulb Always happy to assist!

Well now, good that all wrapped up nicely!
No need to be suicidal about that though
