That is how i was able to report the bug by following all the instructions on the links you provided. If you need something else let me know. dmesg | grep firmware

From below:
AlsaDevices: Error: command ['ls', '-l', '/dev/snd/'] failed with exit
code 2: ls: cannot access /dev/snd/: No such file or directory

It indicated that kernel did not load the driver: check lsmod | grep snd?
And since your kernel version has been upgraded:
Uname: Linux 2.6.32-22-generic i686
so take a look into the directory:
/lib/modules/
modules are there?
Eg, for mine (working fine):
/lib/modules/
./drivers/
./drivers/mpu401
./drivers/
./drivers/
./drivers/
./drivers/
./drivers/
./drivers/
./soundcore.ko
./pcmcia
./pcmcia/vx
./pcmcia/
./pcmcia/pdaudiocf
./pcmcia/
./sound_firmware.ko
./ac97_bus.ko
and of course have to be verified that it is loaded via lsmod as well.

I have noticed that sometimes the sound works, but after a few minutes it just stops working. The info below is after the sound stopped working. The command alsamixer actually gave me a menu to change the settings of my sound card, but this is not always the case because when i turn on the computer and there is no sound from the beginning of the session if i try alsamixer it says no such file or directory.

Not sure what you mean by "and of course have to be verified that it is loaded via lsmod as well" i just ran that command and this is the output

as you can see the lsmod | grep snd did not have any output
the files or directories are present, none is missing on kernel 2.6.32.23-generic

Just to clarify, so u have gone each of the following subdirectories:
/lib/modules/
/lib/modules/
/lib/modules/
and make sure that the kernel modules exists? They cannot be
identical due to kernel version differences. For eg, under my
directory (custom-build kernel):
/lib/modules/
./sound/usb:
total 752
drwxr-xr-x 4 root root 4096 2010-06-18 00:58 .
drwxr-xr-x 12 root root 4096 2010-06-18 00:58 ..

and ensuring the permission are valid, right? (unlikely to have error
if u are doing it by Lucid or apt-get way)
Together with "dmesg"'s output needed as well - do this on the machine
where /dev/snd is not found. "dmesg" should indicate some errors
during kernel bootup, as lsmod does not show any "snd" related modules
being loaded.
Since udev configuration is commonly used by all the different kernel
version - this is unlikely to be the cause of error.

if it is still working, get a snapshot of the lsof output. (this

and then perhaps compare the output with that when the sound is no
longer audible. I suspect some hanging process, opening the drivers,
and never closed it properly. A reboot is often needed (for me at
least, after combining bristol + rosegarden + totem usages in
different order).

Mine is like this:
[ 20.239014] HDA Intel 0000:00:1b.0: PCI INT A -> GSI 22 (level,
low) -> IRQ 22
[ 20.239059] HDA Intel 0000:00:1b.0: irq 29 for MSI/MSI-X
[ 20.239083] HDA Intel 0000:00:1b.0: setting latency timer to 64
Could it be hardware problem? Can you put in the original Ubuntu
10.04 CD and bootup without installation, use it as a LiveCD and see
if there is any sound?

Both aplay cannot detect any soundcard and /dev/snd not detected are
related to kernel module not loaded successfully. So I will focus on
that first.

Question: was this upgraded from 9.10 to 10.04? Hm.....I have
seldom done upgrading....almost 99% bound to cause problem. Just
install from fresh CD...or boot it as LiveCD.

yes, i did an upgrade, and no i do not have a live cd. Since, last time a guy in the irc channel try to help me by doing this:
*if* it fixes the problem. then the solution was adding "options snd-hda-intel probe_mask=1" to /etc/modprobe.
you had the "azx_get_response timeout, switching to single_cmd mode" error messages in dmesg output, and followed the solution suggested in https:/
So it did not fix the problem, it just worked longer for like 2 hrs before again the sound was gone. Now, once again i am having difficulties loading the soundcard, so typing
cat /proc/asound/hwdep
cat /proc/asound/
cat /proc/asound/timers
cat /proc/asound/
gives me no out put.
I wil try later to see if soundcard loads so i can provide you with the requested data.

i see, so it is software problem, nothing hardware. can u recount
how do u get to this stage of getting the software to work again?
(did u do anything, or just simply reboot your machine?)
many bug report is linked to resuming from suspend, and the sound
driver somehow cannot suspend and resume cleanly......but then this is
also resolved at some stage.
The "lsof" which I requested was meant to see which processes open up
which sound ports, and possibly meaning that the kernel has to
multiplex these different applications together with regard to
transmitting sound to the speaker. And if there is no sound, one of
these processes could be the culprit of the failure - which is why u
need to compare the lsof before and after the sound failed. Or how
about comparing your lsof with mine:
/root>lsof |grep snd
pulseaudi 3404 tteikhua mem CHR 116,5

(Ubuntu 9.04 with linus-tree kernel at 2.6.35-rc3).
THis link have lots of suggestion on solving the audio problem:
http://
Anyway, since it is working now.....I hope you can move on something
else. Thanks.

I think it may be a hardware problem, i tried a puppy linux live cd. The same problem no sound card was detected. It just works for a few minutes before going useless again. Do you know any solution? would i be better off buying a new laptop?

Closing that outdated report as EOL has been reached long time ago

I compiled to the latest version of alsa drivers and the sound started working again. However after a few mines sound was gone. Something makes the alsa drives get erased.
