[Alsa-user] Dell latitude E5500 sound and system beeps issues

[mohammed g. <moh...@ho...>]

Hi all,

I have a dell latitude E5500 run slackware 13.1 x86_64

with HDA audio:

00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02)

all sound works ok internal speakers,mic and external headphone,mic
but i have two problems:

1) when i disabled the microphone from the bios alsa driver still can
use the (internal & external) mic and this not happens when
use solaris or freebsd which is right, so how alsa can use
the mic feature after i disabled that from bios. 

2) which is important to me i dont have any beeps
(console, terminal, vim, ...), i know it doesn't alsa mission
to active pc speaker so i load the pcspkr modules ( i do that 
in my old pc and it is work) dmesg say pc speakers is registered
but i cant hear any beeps.
so i did some search and found that alsa can route system beeps
through sound card(snd-hda-intel), so i rebuild the kernel with
that options and it is worked now i can hear system beeps
(noisy sound) but at least it is worked, so my questions is do
i have hardware pc speakers like my desktop pc or laptop dosent
have any pc speakers at all and use system beeps by routing it
through sound card.

please any one can help me i am a guy who like to understand the reasons :)  

sorry for my bad English

thanks .
