Hi Simon, Are you still affected by this bug? For me this chip has worked fine in Maverick (Ubuntu 10.10) and every subsequent release. If it's the same for you then I think we can close the bug. If you still have this problem in the current Ubuntu release, that would also be important to know.

Gnome-alsamixer crashes with: (gnome-alsamixer:2673): GLib-GObject-CRITICAL **: g_type_instance_get_private: assertion `instance != NULL && instance->g_class != NULL' failed (gnome-alsamixer:2673): GLib-GObject-CRITICAL **: g_type_instance_get_private: assertion `instance != NULL && instance->g_class != NULL' failed Segmentation fault ******************* Gamix seems to give access to the sound chip, but does not actually control the microphones. I have had some sound come from the microphone at times, but with a lot of background.
