I have a Lenovo Thinkpad T400s running Ubuntu 9.10 and a co-worker has the same laptop with Ubuntu 10.04 and we have both been suffering from the external microphone not working. None of the solutions mentioned above helped.
We ended up removing pulseaudio and installing esound. Now the settings can be configured via alsamixer and we can use external microphones in Skype etc. I am happy to provide more information on my system if requested. -- External microphone jack not working on Dell Studio 1735 notebook. https://bugs.launchpad.net/bugs/479410 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
