Hi,

I am using a NVidia based motherboard with integrated Realtek 5.1 audio. I installed mandriva 2007, and the alsa is able to work out of the box. The sound output is perfect, but, when i use my mic, the recording volume is very low, even if I crank up all the volumes in the alsa mixer.... I guess some other thing should be done... Is there any tweak I can do with alsa soure code? Please let me know...

Previously, the card was not even detected by earlier versions of alsa that came with mandriva 2006. Now, I am happy that things are working fine.. but, just this problem... If anyone can gude me, I can spend some time in figuring out the problem and add my contribution to the community...

Thanks guyz!!!

Don't know if this will help, but on my SuSE 10.0, the Kmixer panel has a tab for switches, and there's a mic boost +20dB. I don't know if this is hardware dependent, or if it appears or works for other distributions, but I hope it may be of use to you.

You should not be using kmixer. Sometimes it screws up some mixer controls. Use alsamixer or to get the full set of controls use alsamixer -V all.

Most sound cards have mic boost for microphones that have horrible sensitivity. What ahedler have said should work. Sound cards that have external amplifier option needs to be unmuted. Then there are other sound cards that have an ADC or capture mixer. Just make sure it is up to a good level and it is unmuted. Yout have to play around with the mixer settings until you get the results that your want.
