Microphone Problem With HP 8530w After Upgrading To Linux Ubuntu 10.04
My upgrade to Linux Ubuntu 10.04 went very well (previously 9.04), except for my microphone (I have an HP 8530 w elitebook). Sound plays perfectly, and I can hear myself typing and speaking (i.e. the internal microphone loops back to the speakers) but it never works for skype/ audacity / etc.). Everything worked perfectly in 9.04.
I tried many fixes for microphone problems posted here, to no avail. I played around with pavucontrols and alsamixer, tried many suggested options in modrpobe/alsa.conf, and made sure that nothing is muted. pavucontrols shows only one input device instead of two (my internal microphone and the microphone jacks for an external one), and an external microphone somehow works, but way too silent (I can hear a lot of static hiss and my own voice very silently in an external microphone).
Answer :
Finally fixed: After trying different options for two days, I simply purged PulseAudio from my system, and replaced it with esound using “Howto solve all PulseAudio-related issues in Ubuntu” Everything worked fine again without additional tuning.
