I compiled ALSA version 1.0.23 from sources using the following document as a guide: http://monespaceperso.org/blog-en/2010/05/02/upgrade-alsa-1-0-23-on-ubuntu-lucid-lynx-10-04/
Before the upgrade only the following knobs were available in ALSA Mixer: Master, PCM, S/PDIF, Capture, Analog Mic Boost. After the upgrade another knob for Digital appeared. After adjusting the knobs (Digital and Capture on 100%, Analog Mic Boost 20 db), sound capture on external mic works perfect, but internal mic does not work. Internal mic capture volume is very low, the only thing that is captured is popping and crackling noise. -- External/Internal Mic on Lenovo Ideapad U150 (Conexant CX20582- Pebble) does not work. https://bugs.launchpad.net/bugs/598351 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
