I have the same issue in a Dell Precision M90. Following the advice of reporting the "wrong wiring stuff" upstream, I found at alsa's bug tracking system that it is already reported (I think by the gust at the laptop testing team, not sure).
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4890 I am not quite sure to understand, but they say this is the correct behavior specified by the datasheet of stac9200. Maybe someone that is more on topic might take a look to the discussion. ** Bug watch added: ALSA Bug Tracker #4890 https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4890 -- [karmic] Dell Inspiron 9400 / ICH7 - Mixer controlling wrong settings https://bugs.launchpad.net/bugs/441195 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
