[Pkg-alsa-devel] Bug#367773: alsa-base: Driver incorrect behaviour changed

[José Salavert Torres]

Package: alsa-base
Version: 1.0.14-1
Followup-For: Bug #367773

With the last version of alsa, when the system starts, "headphone 
detection" is activated, and "headphone" is activated.

When you plug a headphone set, the "headphone detection" changes to 
muted, and the state of "headphone" remains activated.

"PC speaker" is muted all the time. The "headphone detection" state can 
not be changed manually.

The correct behaviour should be the following:
-> If "Headphone detection" is muted, headphone plug events do not alter 
the system.
-> If "Headphone detection" is unmuted (active):
     +when something (headphones for example) is plugged:
         - "Headphone" unmuted.
	 - "PC speaker" muted.
     +when no headphones are plugged:
         - "Headphone" muted.
         - "PC speaker" unmuted.

For convenience, if the estate can not be saved, at the beggining the 
"headphone detection" should be active, and it should detect if 
something is plugged or not and set the "Headphone" and "PC spaker" 
accordingly.

Please fix this issue, if I can help in something tell me, this year I 
started to study the kernel code at the university.

There has passed too much time for such a simple problem :(
