Title:
[Lenovo IdeaPad Y430] Subwoofer don't mute/unmute on plugging external
acoustics
Status in alsa-driver package in Ubuntu:
Incomplete
Bug description:
Binary package hint: alsa-base
... in Lenovo Y430 laptop(this model includes subwoofer) and Ubuntu
9.04(upgraded from previous version). When plugging external speakers, embedded
front speakers turns off, but subwoofer continue to work.
In preinstalled Windows Vista(with vendor drivers i think), all works fine.
Furthermore, on plug/unplug external speaker in windows hardware remembers
state and subwoofer keep it in linux.
