[SOLVED] HP dv4 1070 - Sound Problem

[PR_FM]

Hi ,
I have ubuntu 9.04 on my laptop ( HP DV4 1070 ) & I have this problem : when a sound finished (either music, logging in sound, ...) it hanged & repeated forever till I start to play a sound again,
I used some solution like add something in the alsa base file ( I don't remember ) but I still have the same problem ,
I have one more problem that I can't hibernate & stand by , but sound problem is more urgent.
please help me throw it,

Please show us the output of

lspci -nn | grep audio

That will tell us the exact card you have and we can possibly search for a solution (if it's a known problem).

it dous'nt have any output for me !!!

[D-cat]

lspci -nn | grep -i audio

Forgot the "-i", sorry. That will allow "audio", "Audio", or "AUDIO"; without it, it's "audio" only, which isn't always the case. My bad.

the response of what you said:

00:1b.0 Audio device [0403]: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 03)

Okay, I looked this problem up and got a list of things to try... in order based on ease and success:

Modify /etc/modprobe.conf
Modify /boot/grub/menu.lst
Remove PulseAudio
Recompile ALSA from source

For modprobe, the proceedure is simple; in a terminal window:

sudo echo options snd-hda-intel enable_msi=1 >> /etc/modprobe.d/options

You only do this once, and there is no feedback. Simply reboot after and see if this resolves the problem. If not, step 2

[Alt + F2]

gksu /boot/grub/menu.lst

(password)

Scroll down, then edit the kernel line under the default (usually first) menu item and add at the end pci=noacpi . It'll look something like this:

title          Ubuntu 9.04, Kernel (version)
uuid           (boot partition's uuid)
kernel         /boot/vmlinuz-(version) root=uuid=(uuid) ro quiet splash pci=noacpi
initrd         /boot/initrd.img-(version)

Save the file and once again reboot.

If that fails, then on to attempt 3, removing PulseAudio.

There is already several pages dedicated to this, so rather than re-invent the wheel, I'll just point you to the one I particularly like best. It was written for Ubuntu 8, but I think it's still valid for 9:
Howto solve all PulseAudio-related issues in Ubuntu|Ubuntu Geek

I'll reserve the last part for later, I'm hoping something here fixes your problem first. Good luck!

thanks a lot D-cat
the first one worked for me , but it's weird that i did that before & now it's solved.
do you have any idea about suspend & hibernate problem !?

[MikeTbob]

It would probably be best if you created a new thread for suspend & hibernate problem. It gets more exposure that way too. You can also mark this one as solved.

[D-cat]

I will mention that hibernation in Linux is incomplete at best. It works on some laptops, it doesn't on others. There's lot of issues when it comes to bringing hardware back into the same power state it was in before the power was cut off. IMO, with session saves on and the speed at which Linux boots, hibernation isn't all that necessary anyway.

Suspend however is another issue, that should be working. I agree with Mike though, you should start a new thread before getting technical.
