Public bug reported:
Alsa 1.0.14-rc1 should be merged in Feisty tree as it introduces bugfixes for
Conexant HD audio chipsets (present in the latest HP Pavillion notebooks).
Conexant users now can't use nor headphones nor microphones and don't have all
the correct sliders in alsamixer.
Taken among the many changes from the alsa-project.org changelog for
version 1.0.14-rc1:
- hda-codec - Add missing array to conexant driver
This patch adds a missing array to the conexant driver.
- Add Conexant audio support to the HD Audio driver
This driver adds limited support for the Conexant 5045 and 5047 HD Audio
codecs. Some issues still need to be resolved. The code is based
primarily on code from the Analog Devices AD1981 support and the Realtek
ALC260 support. Some code came from the original code developed by Alex
Pototskiy (see alsa bugtracker 2485).
** Affects: alsa-driver (Ubuntu)
Importance: Undecided
Status: Unconfirmed
