[alsa-devel] Request for Realtek patch - Nvidia MCP51 HDA / ALC883 (10de:026c) Notebook component

Fri May 9 18:13:27 CEST 2008

Actually, this dual usage headphone jack is quite common among laptops
that have digital out.  By default, though, Alsa should probably turn
off spdif for power savings.  I'm (slowly) working on a mechanism that
can trigger a popup application when a device is inserted to a jack with
sense enabled.  The idea is to be able to popup an app so users can
toggle between analog headphones or spdif on systems like yours, or
between 2nd headphone/microphone on other systems that support HP Amp on
multiple ports.
