Welcome to the new Linux Foundation Forum!
no sound
in Multimedia
I can't get any sound at all on any linux distros (live or installed)
that I tried.
alsamixer and alsactl seem to be working
my
# cat /proc/asound/cards
outputs this
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xdf300000 irq 11
Whenever I try listen to a sound file, the application
(amarok, k3b, ...) I use remain silent and
doesn't display an error message
I have an hp pavilion dv4-1199ef laptop (purchased
in March 2009).
I have no clue on what might be the reason for this
(alsa, kernel, ...?)

Thanks,
thanks, also to vonbiber for asking about sound problem
What distribution of Linux are you running? How new are you to this stuff? If very new, I'll take extra care trying to explain to you how to change those library files that I mentioned in my post above.
I'm an intermediate user. I'm comfortable with the console,
the shell, (re)building the kernel, etc.
the hda intel is built in the kernel (not as a module)
I use slackware 12.2
my laptop is very recent: hp pavilion dv4-1199ef
Have you made any progress? Do you have system sounds: startup, shutdown, error, etc.?
other than that nothing
in kde even when I turn the notification system sounds
there's nothing either
From the command line as root:
Follow the steps, reboot. Let me know if you have sound.
displays this message
no supported PnP or PCI card found
and yet, when I run this
# lspci | grep -i audio
it displays this
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)
I noticed that slackware uses a
/etc/rc.d/rc.alsa
I know that it's run at boot time (it's in mod+x) and I don't
get any error messages in dmesg
I'm beginning to run out of ideas. See HERE for some things to check.
Also, I noticed you registered at Scot's. I sent you a Welcome PM, by the way. Post about this in All Things Linux there. Bruno will solve it for you. I can almost guarantee it.
> modprobe snd-hda-intel
If there is not this module, see config kernel
>cat /boot/config-bla-bla-bla | grep CONFIG_SND_HDA_INTEL
a module
but even when it's built as a module (which I did with
the last kernel I built---linux-2.6.29.4) it's still not working
and the lsmod does display all the sound modules
given the number of posts I saw elsewhere I think there's
an issue with this card
so I keep trying to build new kernels, hoping that eventually
someone'll come with a fix
>modinfo snd-hda-intel
There is lot a parametrs.
parm: index:Index value for Intel HD audio interface. (array of int)
parm: id:ID string for Intel HD audio interface. (array of charp)
parm: enable:Enable Intel HD audio interface. (array of bool)
parm: model:Use the given board model. (array of charp)
parm: position_fix:Fix DMA pointer (0 = auto, 1 = none, 2 = POSBUF). (array of int)
parm: bdl_pos_adj:BDL position adjustment offset. (array of int)
parm: probe_mask:Bitmask to probe codecs (default = -1). (array of int)
parm: single_cmd:Use single command to communicate with codecs (for debugging only). (bool)
parm: enable_msi:Enable Message Signaled Interrupt (MSI) (int)
my pcm level is not set at 0 (it's set at 71)
one weird thing I noticed is that the sound card uses
a certain irq on my installed slackware
and another one on my live slax linux
here's the 2nd line of 'cat /proc/asound/cards'
from slackware;
HDA Intel at 0xdf300000 irq 11
and from slax:
HDA Intel at 0xdf300000 irq 22
For example, my laptop needed the following option (which probably won't be the same as what you need):
Whereas my cousin's laptop (a Toshiba Satellite Pro) needed this line:
Hope this puts you on the right track.

I already wrote an /etc/modprobe.d
where I tried different values for model
based on what I read in the
/Documentation/sound/alsa/HDA-models.txt (or something like
this) in my kernel source tree, and that'd could fit for an hp
laptop
the latest I tried was model=laptop
it seems the alsa files in linux-2.6.29.4 are not up to date with
the latest alsa (1.20) because in the alsa docs from the
latest version I dowloaded there were some other models
not listed above, such hp-dv5 (which might cover the
hp dv4 series)
