eddiep Posted October 14, 2008 Report Share Posted October 14, 2008 (edited) SOLUTION: ALL DIGITAL INPUT/OUTPUT CHANNELS HAD TO BE ENABLED AND SET TO A 50% VALUE EVEN IF I HAVE NO SUCH CHANNELS IN USE. TO HIGH VALUE RENDERS MICROPHON USELESS RESULTIN IN A SILENT BACKGROUND NOISE, TO LOW VALUES RELUST IN SILENCE. ===================== Mandriva 2009.0 KDE 4 I installed it on my HP Pavillion dv6000 laptop. Everything was fine, but suddenly the microphone stopped working. Microfone tested - good. sound playback - working Sound recording - nothing. Perfect silence, or some noise. With mandriva 2008 there were no problems. What I tried: - reset settings to default from MCC - reset setting to default from KDE CC - alsamixer in console, set everythign to max - kmix ... play with different settings ... nothing - lot of restarts between settings change - disable pulseaudio - try other microphone I have perfect playback of music but no recording whatsoever. The internal mic is not working, the external mic is not working. ADDITIONAL INFORMATION: root@localhost csabi]# cat /proc/asound/card0/codec#* | grep Codec Codec: Conexant CX20549 (Venice) [root@localhost csabi]# lspcidrake -v | fgrep -i AUDIO snd_hda_intel : Intel Corporation|82801G (ICH7 Family) High Definition Audio Controller (vendor:8086 device:27d8 subv:103c subd:30bb) Any help would be appreciated, it is very important on this laptop to have proper sound. I use it frequently for voice confernces. Edited October 14, 2008 by eddiep Link to comment Share on other sites More sharing options...
tyme Posted October 14, 2008 Report Share Posted October 14, 2008 did alsamixer and/or kmix have a section for recording volumes? there may also be a setting somewhere for +10db mic boost, which is necessary with most mic's. other than that, sounds like an odd problem if it was previously working.
