no sound (onboard chip)

[wiko]

mobo:  AM2NF3-VSTA with onboard C-media CM6501 7.1 ch audio compliant with UAA-architecture

sound is no problem in a few other distro's I've tried.


PCLOSCC says:

No Sound Card has been detected on your machine. Please verify that a Linux-supported Sound Card is correctly plugged in.

You can visit our hardware database at:

Note: if you've an ISA PnP sound card, you'll have to use the alsaconf or the sndconfig program.  Just type "alsaconf" or "sndconfig" in a console.


This gives:
alsaconf: nothing happens
and
Failed to execute child process "sndconfig" (No such file or directory)

I've checked the forum for solutions, but nothing applied.


can this be solved?

thx in advance

run alsaconf as root in a terminal    hopefully it will do something  ...

[wiko]

that gave 2 possibilities: tried both, still no sound.

?

more suggestions?

thx in advance,

what says alsamixer?
Is it on mute?

[wiko]

how do I start alsamixer? Alt-F2 didn't do anything.

in the menu there is Gmixer, but clicking this does nothing either.

tia,

Check if a driver for the cmedia device is loaded

You should get an output like this if it is

Code: [Select]

[root@XPS user]# lsmod | grep -i cmedia
snd_hda_codec_cmedia     7135  0
snd_hda_codec          80148  4 snd_hda_codec_cmedia,snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_inte
If not then try loading it

Code: [Select]

[root@XPS user]# modprobe snd-hda-codec-cmedia

Then see if there is any change .......

If the driver is needed to be loaded at each boot that can be done by listing it in

/etc/modprobe.preload

[wiko]

[root@localhost root]# alsamixer
cannot open mixer: No such file or directory
[root@localhost root]#

I could start Gmixer this way, but no matter which device I chose, nothing was muted.


then:

[root@localhost root]# lsmod | grep -i cmedia
[root@localhost root]# snd-hda-codec-cmedia
bash: snd-hda-codec-cmedia: command not found
[root@localhost root]#

first command returned nothing, second one the not found message as above.

are we any closer??

Try;

[root@localhost root]# modprobe snd-hda-codec-cmedia                   <Enter>

[wiko]

[root@localhost root]# modprobe snd-hda-codec-cmedia
[root@localhost root]#

did it do anything? nothing happened it seems.

Now try;

[root@localhost root]# lsmod | grep -i cmedia                      <Enter>

[wiko]

tried again, and the command now returns something:

[root@localhost root]# lsmod | grep -i cmedia
snd_hda_codec_cmedia     7135  0
snd_hda_codec          75755  1 snd_hda_codec_cmedia

snd_hda_codec          75755  1 snd_hda_codec_cmedia

So it shows that the module has in fact loaded. Again, as root, try the alsaconf command. Following that, check your choice of mixer to see that all of the sliders are up, and nothing is muted.

[wiko]

[root@localhost root]# alsamixer
cannot open mixer: No such file or directory

I started Gmixer this way and again sliders up and no mutes, but still no sound either.

and still can't start it from the menu (nothing happens)
