alsa-problem

Nikosis · 05-21-2006, 09:10 PM

Hi
I've got soundblaster Live, after I rebuild my kernel, I can't get alsamixer works.
[HTML]alsamixer: function snd_ctl_open failed for default: No such device
[/HTML]
alsaconf doesn't work either
[HTML]no legacy drivers are available[/HTML]

I've got sound just on one speaker, when Ichange it on alsa I've got something like this
[HTML]Sound server informational message:
Error while initializing the sound driver:
device: default can't be opened for playback (No such device)
The sound server will continue, using the null output device.[/HTML]

thx

have you installed alsa-lib and alsa-util?
if you are using kernel packages from Slackware, have you installed alsa-driver packages that matches with your kernel version?

Hi
so,do I have to reinstall it or...
I'm using 2.4 kernel
I didn't switch to 2.6 kernel so everything should be installed already.
thx

Hey I had something like this happen to me. For some reason my kernel just didn't make the module for my sound card.

Later to find out that I had a broken compiler.

I would say un-install that kernel and recompile it again. make sure the sound card is check off with a dot meaning module.

EDIT: oh I just read this again, you never changed kernels, you just opened up "make xconfig'd" and unchecked stuff and re-made the kernel? Is that what you did?
That card I believe is in alsa and oss sections too.

If that don't work I think you may have what I had which is a broken compiler, and I had to reload. Seemed easier than hours of investigation, etc.

I also had a few sound problems after a fresh install. For me, compiling anything relevent to sound as a modules instead of hard codeded into the kernel seemed to work for me. Make sure you have "sound support" as a module, then under that check off alsa and the appropriate sound driver under it as a module <M> also. Once you are done making new modules, run 'alsaconf' and 'alsamixer' to configure. If it still does not work, please post back the output of 'lsmod'.

2.4 kernels doesn't include ALSA, get alsa sources from http://www.alsa-project.org and compile them.

Be sure to disable OSS so it doesn't conflict with it. Oh, and if you want to use OSS instead of ALSA, remove the modules from /etc/hotplug/blacklist so they are loaded by hotplug.

drkstr · 05-22-2006, 09:32 AM

You can also install the alsa-driver from the Slackware install medium. I've never actually used sound when I had 2.4 kernel so I could be mistaken about this, but I noticed you do not have soundcore module loaded. Did you compile "Sound Support" as a module? I also have an AC97 chipset sound card, but I have the driver module as well as 'ac97codec' I only saw the latter.

Just curious, why haven't you made the upgrade to the 2.6 kernel? You can probably get sound working in 2.4 but it is supported much better in 2.6. You can get the 2.6 kernel from Slackware in the testing/ directory or download from kernel.org if you are interested.

Hi
Yes, maybe I should, ok I'll try.
I've got one more question about hotplug actually, how or where can I check what is loaded by hotplug?,
Do I have to use it, can I just load what I need by modprobe?

Thx
Nikosis

gbonvehi · 05-22-2006, 12:22 PM

You don't need to use it, you can modprobe what you want, it's up to you.
To disable hotplug just remove the executable attribute of the script: chmod -x /etc/rc.d/rc.hotplug
Hotplug will take a look at your hardware and load a apropiate module for it, I can't tell you what it will load, but i'm sure that what's on /etc/hotplug/blacklist won't

Most (maybe all) the list you've in lsmod is loaded by hotplug if you're not doing it manually, so be sure to modprobe all that stuff, which can be done in /etc/rc.d/rc.modules

Hi
Well. I've got it upgrade to 2.6 , everything works fine a little bit faster even.
With small exeption : a mouse
I can not get scroll works
[HTML]
Section "InputDevice"

# Identifier and driver

Identifier "Mouse1"
Driver "mouse"
Option "Protocol" "IMPS/2"
Option "Device" "/dev/mouse"
Option "ChordMiddle"
Option "ZAxisMapping" "4 5"[/HTML]

Probably I checked something which not suppose to be checked
Any Idea what could be wrong?

Thx

drkstr · 05-22-2006, 06:20 PM

What kind of mouse do you have? If it is a usb mouse, you might need to enable:

Code:

Device Drivers  --->
    Input Device Support  --->
        <*> Event Interface

in the kernel.

Nikosis · 05-22-2006, 07:54 PM

Hi
I've got it compiled as a module, so this part is ok.
what was wrong is that busmouse driver have been compiled into kernel, thats why I couldn't load the right one.
It works properly now.

Thanks everyone for help

By default, Slackware comes with ALSA disabled in the kernel. If you left it that way then install slackware-current/source/ap/alsa-driver using the SlackBuild in that directory. After you do so, ALSA will work again.

Nikosis · 05-23-2006, 06:44 PM

Hi
I'd rebuild my kernel, so it works.

Thx
Nikosis
PS.Should I use alsa-driver from slackware-curent?
