Sound strikes after little playing with arch

Hallo,

nachdem ich nun seit einer Weile mit Ubuntu und Fedora experimentiert hab, wollt ich mich nun mal an Arch versuchen. Der Anfang hat auch sehr gut geklappt. Mit 64Bit und KDE läuft das ganze super.

Allerdings tut nach einigem rumspielen mein Sound nicht mehr.

lspci -v | grep -i audio

liefert mir:

00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
01:05.1 Audio device: ATI Technologies Inc RS780 Azalia controller

also findet er vermutlich meine soundkarte (den chip auf dem mainboard)

in /dev/... kann ich jedoch kein Gerät finden, das mit snd beginnt.

Kann es sein, dass ich das Modul irgendwie aus dem Kernel geschmissen hab?
Was könnte sonst der Grund sein?

I'd love to learn German some time, but I don't think it will help you get many answers around here. I mean, please show me just one other post that is not written in English.

Re: Sound strikes after little playing with arch

oh shit the whole site is translated so i thought i'm on archlinux.de. dough. sorry.

okay once again, now in english .

now i've been working with arch for a few days (before i've done some things with ubuntu and fedora).

everything went fine. i use 64bit and kde. i tried some things. and suddenly after a restart there was no sound anymore.

so i tried

spci -v | grep -i audio

and it found

00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
01:05.1 Audio device: ATI Technologies Inc RS780 Azalia controller

But there are no devices that begin with "snd" in the "/dev/".

Is ist possible that kickt the sound module out of the kernel somewho?
What could be the reason for that?

Re: Sound strikes after little playing with arch

Are you using Alsa, oss or PA?

I think you should also change the thread's title :-)

Edit:
When pasting code, please use [ code ] tags https://bbs.archlinux.org/help.php#bbcode

like this

It makes the code more readable and more convenient to scroll through.

Re: Sound strikes after little playing with arch

Your sound card appears almost identical to the one I have on my Debian box (which uses ALSA):

$ lspci | grep -i audio
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) (rev 40)
01:00.1 Audio device: nVidia Corporation GF104 High Definition Audio Controller (rev a1)

Now consider the following output:

$ lsmod | grep snd
snd_hda_codec_realtek   174583  1 
snd_hda_intel          15419  2 
snd_hda_codec          55141  2 snd_hda_codec_realtek,snd_hda_intel
snd_hwdep               4150  1 snd_hda_codec
snd_pcm                47947  2 snd_hda_intel,snd_hda_codec
snd_seq                35627  0 
snd_timer              12314  2 snd_pcm,snd_seq
snd_seq_device          3857  1 snd_seq
snd                    35281  12 snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_seq,snd_timer,snd_seq_device
soundcore               3450  1 snd
snd_page_alloc          4925  2 snd_hda_intel,snd_pcm

So yeah, I think you have problems with modules getting loaded.

I notice in my /etc/modprobe.d/, I have two alsa-specific files. Could you give us "ls /etc/modprobe.d/"?

Re: Sound strikes after little playing with arch

when somebody tells who to change the title i will do.

i'm using the standard sound of arch, so i think its alsa (i also configurated my sound with alsamixer).

ls /etc/modprobe.d tells me

modprobe.conf  rc.conf

Re: Sound strikes after little playing with arch

Edit your first post to change the title.

Why do you have rc.conf in /etc/modprobe.d ?

Re: Sound strikes after little playing with arch

the content of rc.conf:

# Autogenerated by systemd, do not edit

so it is probably from systemd

Re: Sound strikes after little playing with arch

so i have to rebuild my kernel and include those sound modules? or is there a simpler way?
or it is possible to build the kernel as arch installed it at the installation of arch?

My hunch is that rebuilding the kernel is probably not necessary. Did you remember to include necessary modules in rc.conf?

Re: Sound strikes after little playing with arch

no i didn't include the sound module.
i dont' know how to do this or rather how the right module is called

Yeah, I don't know either. I'm still new to Arch and haven't set up sound yet. That will probably be a project for me this weekend. So maybe after I do that, I will find it easier to help you :-)

Re: Sound strikes after little playing with arch

MODULES=(snd_hda_codec_realtek  snd_seq)
adding that in your /etc/rc.conf should probably do the trick without having to custom build your kernel.
