Well I have no sound yet again.

Jamendo has no sound.

You Tube opens up with SMplayer but has no sound.

Gogglesmm gives me a message,

Session bus not available.All features requiring dbus are disabled

then,

Unable to initialize audio driver

If I check in a terminal I get,

CODE

# lspci | grep -i audio
02:08.0 Multimedia audio controller: C-Media Electronics Inc CMI8788 [Oxygen HD Audio]

So where is my sound. !!!!

I'm lost any ideas folks.  

[amenditman]

It's possible your system is trying to use an alternate (non-existant) audio device. Mine occasionally creates virtual copies of my sound device and sets the new one as default. I usually check alsamixer then the alsa ArchWiki page. Something to do with aplay or asound if I remember correctly.

From the ArchWiki ALSA page

Set the default sound card
In Kernel Space

Telephony-capable modems and modern graphics cards with HDMI output can conflict with the sound card for the default sound card slot. (pcspkr is another, non-ALSA PC speaker module. It will not conflict with ALSA sound cards.) To prevent this, discover your sound card model name with lspci(8) and your ALSA driver module names with ls(1):

CODE

$ ls -l /sys/module/snd/holders

Or better (source[1]):

CODE

$ cat /proc/asound/modules

Then add the names of your sound card modules to (source[2]):

/etc/modprobe.d/alsa.conf

Well I followed securitybreaches advice and got sound last week.

I just disabled my secondary audio using this:

I'm totaly lost on this.

From the Wiki

ALSA is included in the default Arch kernel as a set of modules, so installing it is not necessary.

udev will automatically probe your hardware at boot, loading the corresponding kernel module for your audio card. Therefore, your sound should already be working, but upstream sources mute all channels by default.

The current version of ALSA installs with all channels muted by default. You will need to unmute the channels manually.

It is easiest to use alsamixer ncurses UI to accomplish this (alternatively, use amixer from the commandline):

$ alsamixer

Here is what I get,

CODE

$ alsamixer
cannot open mixer: No such file or directory

CODE

# alsamixer
cannot open mixer: No such file or directory

CODE

# alsaconf

Tells me "no legacy drivers are available"

and yes I read,

Warning: Do not use alsaconf if you have a PCI or ISAPNP sound card, as the entries alsaconf adds to the modprobe.conf file might break udev's autodetection.

but my "modprobe.conf" is empty so I recon that shows that "alsaconf" is doing sweet zip for me.

This Arch install is turning into a nightmare   I did not have half as many problems last year when I did my first install and I knew nothing at all  

[amenditman]

Check if you can install or have installed alsa-utils from the extra repos.

CODE

[amenditman@amendesk ~]$ yaourt -Ss alsa utils
extra/alsa-utils 1.0.25-1 [installed]

This package contains the alsamixer and some other stuff you need.

Did that last week. That is how I unmuted the sound.

looks like they are still installed.

I have several suggestions: first post the result of the command securitybreach mentioned in his above post.
-Go into the BIOS and disable the soundcard you are not using, then reboot. Check alsamixer to make sure it's unmuted and levels are up, test for sound (this works for my system with onboard chip and Audiophile 2496 PCI card)
-If no luck try, if it's not listed in the lsmod output (as root)

  sunrat + securitybreach

I followed the link and tried

CODE

modinfo soundcore

which of course showed the module loaded in the kernel.

However it mentions "/etc/​modules.conf" which I have but it is empty . Is it worth my while doing,

Here's the example for this card. Copy and paste this to the bottom of your /etc/​modules.conf file.

# ALSA portion
       alias char-major-116 snd
       alias snd-card-0 snd-oxygen
       # module options should go here
      
       # OSS/Free portion
       alias char-major-14 soundcore
       alias sound-slot-0 snd-card-0
      
       # card #1
       alias sound-service-0-0 snd-mixer-oss
       alias sound-service-0-1 snd-seq-oss
       alias sound-service-0-3 snd-pcm-oss
       alias sound-service-0-8 snd-seq-oss
       alias sound-service-0-12 snd-pcm-oss

Or seeing as I have sound should I just keep me fingers crossed and leave things a s they are.  

Oh and of course many many thanks for the help

Whenever you do a kernel upgrade, some of the modules and other things do not load correctly until you reboot.

Yup I remember that very fact came up here recently.  

[sunrat]

Yay, it's working! snd-oxygen has obviously been renamed to snd_oxygen since that alsa page was written, and it is already loaded.

[abarbarian]

Yup the B52's sound greaaaaaaaat  

Thanks guys.  

[abarbarian]

Well once again I have no sound. I tried to fix it but had no sucess so I thought. What if I delete files and folders( I had lost trck of what had been altered) and uninstall some alsa stuff. Then reboot. Then reinstall the alsa stuff do a pacman -Syu and reboot. But no joy.
When I try to run alsamixer I get (see the end of the code)

I find this warning in the Alsa Wiki very puzzling,I have a ASUS Xonar DS PCI sound card.

and now from  # cat /proc/asound/modules I output

CODE

[root@longship bloodaxe]# cat /proc/asound/modules
0 snd_hda_intel
1 snd_virtuoso

So it looks like the sound cards have swapped places  

[abarbarian]

The Arch Wiki also says this

Or better (source[1]):

$ cat /proc/asound/modules

Then add the names of your sound card modules to (source[2]):

/etc/modprobe.d/alsa.conf

options snd slots=snd-intel8x0

These entries ensure that the Intel 82801DB-ICH4 sound card will become card 0 and the PC speaker will become card 1. If there's more cards that have to fall into specific order, their modules can be given to “slots” option as follows:

/etc/modprobe.d/alsa.conf

options snd slots=snd-intel8x0,snd-interwave

This way cards driven by snd-intel8x0 module are enumerated before interwave cards.

Trouble is I do not have "/etc/modprobe.d/alsa.conf" only thing I have in "/etc/modprobe.d/" is a empty file "modprobe.conf"

[V.T. Eric Layton]

Sure... go ahead and ignore me. In the end, we always resort to the nuke from orbit option.

[sunrat]

I mentioned it before, but again I suggest to go into BIOS and disable onboard sound.

[securitybreach]

Running "/etc/init.d/alsasound restart" or "/sbin/alsa force-reload" outputs this

CODE

[root@longship bloodaxe]# /etc/init.d/alsasound restart

[root@longship bloodaxe]# /sbin/alsa force-reload
bash: /sbin/alsa: No such file or directory
[root@longship bloodaxe]#

I agree with Eric but the reason you are getting "No such file or directory" is because that is not how you stop|start|restart a daemon (alsa). In order to do this, you have two options:

CODE

/etc/rc.d/alsa start|stop|restart

or

CODE

rc.d stop|start|restart alsa

You can replace alsa with whatever daemon(service) you want to modify and use one of the three options listed. Ex:

CODE

rc.d restart alsa

The daemons(services) loaded at boot are listed at the bottom of /etc/rc.conf:. Ex:

CODE

╔═ comhack@Cerberus 10:48 PM
╚═══ ~-> cat /etc/rc.conf | grep DAEMONS
# DAEMONS
DAEMONS=(hwclock syslog-ng @network @netfs crond @alsa @dbus @sensors !ntop @mpd @openntpd !vboxdrv @sshd !tor @pgl)

BTW the @ means to background the service so the next one does not have to wait for the previous one to finish (faster bootup). The ! is used to disable the daemon from starting at boot.

[amenditman]

I mentioned it before, but again I suggest to go into BIOS and disable onboard sound.

I use a Bose USB sound system.
Used to have a bunch of inconsistant sound troubles.
Went into the BIOS and disabled the onboard sound and now have much less trouble. Not none, just a lot less.
