I have not used this script in several months and I can not remember. I do know that you need to cut and past it into kwrite and then save it with a title like sound or etc. then you need to make it executable by doing a " chmod +x sound " then I just do not remember from there but I believe that you will need to do a "./sound " to execute it. I am sure that someone will chime in with more knowledge of script writing than I have. I have been using it and it works well, it will give you more volume than you need on most any computer.

run 'alsamixer' (no quotes) in terminal and boost the volume there...

then run 'rexima' and do the same.

If I see it right, it is actually NOT a script but a config file that you can put in either /etc/asoundrc for global settings or ~/.asoundrc for specific user. I currently have a basic asoundrc to get my HDMI working and it looks very similar to this code.

Increase volumn with kmix

This is the way to install the script or conf file whichever it is, either way it just works'

Open kwrite, copy & paste the file into kwrite. Now save the file at /etc/asound.conf. The asound.conf was not there in slack 13.1 so kwrite created it. /etc/ is the directory, asound.conf is the new file name. You must reboot and maybe even stop/restart kmix for it to work, there will be a preamp slider on kmix now, just slide it to where you need it.

Here is some real good info on this subject.

thanks

I think this problem is annoying enough for a lot of users, so I added some more detail here: http://alien.slackbook.org/blog/addi...-sound-levels/

Eric

I can not get Kmix to display the pre-amp slider. It is not in the list of Available Channels. My /etc/asound.conf file is a straight copy/paste of the code here. I have restarted the machine as instructed. I am running 13.1_64. I have an Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03). A screenshot of my mixer windows is shown below. Any ideas?

Thanks,
Eric

Attachment 4245

When you change "type plug" to "type hw" and then restart the computer, does the Pre-Amp control appear?

Eric

No hw does not make Pre-amp available. I just noticed that I have a file asound.state with the following contents:

perhaps I have to add a control.20?

[snipped the rest off ...]

I have a very similar asound.state for my card, which is also recognized as "Intel" (the Chip is a "Realtek ALC268"). And I have the same problem with the softvol plug -- no matter if I call it "plug" or "hw", I don't get an extra volume slider.

EDIT: Somehow ALSA has a problem with this card. dmix is not working, too, when I try "speaker-test". The second instance just tells me that the resource is busy.

ncmpcpp dont work with that

I have the same video card:

Code:

00:1b.0 Audio device [0403]: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 03)

and Slackware 13.1 64-bit x86_64, with multilib.

and i first try with the

Code:

type plug

reboot and .... didn't work, so i try with the

Code:

type hw

reboot and didn't work.

Was late so i turn off my laptop a go to sleep, then when i come back to my laptop, i launch ncmpcpp and didn't work, so i try to use the command play and didn't either. So i went to alsamixer and see the Pre-Amp thing, i wasn't expecting that, Then i edit the file

Code:

vim /etc/asound.conf

and change, again,

Code:

type hw

for

Code:

type plug

reboot a there it is. It's amazing how much sound i was wasting in my laptop.

With the happiness of have the things working, i went back to ncmpcpp and works, but the volume was to high, and when i try to change the volume (you know with the arrow keys) didn't work now a can't change the volume inside the ncmpcpp will i have to go to alsamixer for that? i don't thing so, so much work, so i remove the /etc/asound.conf and reboot, just for see if that was the problem, and yes that's the problem.

Anyone have a suggestion for this problem?, with the ncmpcpp volume that don't work with the asound.conf fix of this thread.

Munra,
After reading your post I checked alsamixer again and there it was! I still don't have it in Kmix but I cranked it all the way up and stored it....nice now I can make some noise.

I cannot tell what made it, but there it is too. Call it the pre-amplifier magic ;)

Either it was jumping through the alsamixer play/record/all settings with the tab key or loading the sound module with an option for my laptop. Or my computer is just fooling me, that is what I suspect.
