Solve* ALSA problem

Hello all!
I'm a new user of this forum, and first of all, i would like to thank thins community for helping me migrating from ubunto to arch linux, which i do like very much because of it's freedom of choice and it's challenging installation.
As a new Arch user, i had and have some issues that i had to overcome.
One of them was to put ALSA to work correctly.
First, i'm going to describe my system:
- hp dv25699ep
- (uname -a)  Linux (none) 3.3.2-1-ARCH #1 SMP PREEMPT Sat Apr 14 10:08:43 UTC 2012 i686 Intel(R) Core(TM)2 Duo CPU T7500 @ 2.20GHz GenuineIntel GNU/Linux
- DE -> xfce4

My issue with ALSA was that i had a scale that i was not used to see, i only could get sound from "unamplified" to "100%", and from "100%" to "infinity".
The thing was that the sound did not raised linearly, causing the "boom" effect, it raised from mute to "boom" in a little space of the scale.

After many hours searching, i found this website: https://gist.github.com/1904230
which helped me a lot. For those who can't access the website, here's what is says:
Copy pulseaudio configuration template to home folder.

1. cp /etc/pulse/default.pa ~/.pulse/default.pa
2. Append ignore_dB=1 to line with load-module module-udev-detect.
3. Make sure "speaker" volume is at 100% using alsamixer (press F6 and select HDA NVidia to see more volume controls.
4. To make "speaker" volume persist between boots, run alsactl store -f ~/.asoundrc then make alsactl restore -f ~/.asoundrc start when logging into your user. (See Arch Wiki - ALSA)
5. Profit.

I read somewhere that the alsa driver was not sending the right dB's to pulse, and pulse simply improvised, is this strange?

I have now verified (after the upper solution) that at 20-30% i can't almost hear anything(no, i'm not deaf ), have anyone got a solution or this is normal?

Thank you!

Re: Solve* ALSA problem

Why are you thinking that pulseaudio can fix a problem with ALSA?

You need to fix ALSA. Try the "model=" options (there seems to be a recent trend to ignore these - bizarre).

Did the sound work OK in Ubuntu, on that laptop?
