Sound trouble on certain HP laptop (in my case : dv7 1070)

Bug #269586 reported by Alexandre Jacob on 2008-09-12
This bug affects 3 people
Affects Status Importance Assigned to Milestone

Bug Description

When my laptop (HP dv7 1070e) is playing a sound, either there is no sound, either it is a very poor quality (with a kind of repetition of a short clip on a time interval of a few seconds).
The bug is independent from the speakers (for example, if I plug an headset, the trouble is still present)

Searching on the web, I found a tip to correct this : adding pci=noacpi at the end of kernel line in /boot/grub/menu.lst
Indeed, when acpi is disabled, the sound is played correctly.

However, I think this is not a good way to fix that trouble, because then, a CPU core is missing.

I know I'm not in that case, other persons I know have exactly the same problem with other HP laptop model (dv7 1035...)

Sorry for my approximative english.

Here are some information:

lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)

uname -r
Linux me 2.6.24-19-generic #1 SMP Wed Aug 20 17:53:40 UTC 2008 x86_64 GNU/Linux
(unmodified Hardy Heron. Note that I also tried 7.10, 7.04 and 8.10 alpha5 all 64 & 32 bits and no change)

lsb_release -rd
Description: Ubuntu 8.04.1
Release: 8.04

If you need more, just ask me what.

EDIT : I found something strange...
acpi = on
sound under ubuntu = buggy
sound played through WINE 1.1.4 (winecfg => only when both ALSA and OSS are checked - if OSS isn't checked, sound is buggy) the sound is correct!!

I'd like to add that when using Virtual Box with "Pulse Audio", sound is "crazy".
If I choose "OSS" sound is perfect!

I can confirm that the issue affects HP Pavilion dv7-1080ew as well. Tried on Ubuntu 8.10 Alpha 5.

I bought an HP Pavilion dv7-1070ev 10 days ago. I have the same problem with sound. Do we have any news about fixing this bug?

lbitb (lothar-blaha) wrote :

My problems with a Pavilion dv7-1015eg are looking similar:
1. On Hardy and Intrepid I discover "a kind of repetition of a short clip...".
2. On Hardy I have success with the noapic boot option
3. On Intrepid this does not work any longer. "noacpi" and "pci=noacpi" are not working too.

If I move my mouse with is connected to a USB port, the sound is ok! - if I let the mouse alone, the sound shows the kind of repetition again...
Maybe this triggers some alsa adept to see what's wrong.

lbitb (lothar-blaha) wrote :

Last evening I have installed the current intrepid updates and I have compiled and installed the latest alsa sources (development versions
alsa-driver-1.0.18rc3, alsa-lib-1.0.18rc3, alsa-utils-1.0.18rc3). After that I have tried some alsa and kernel options again (kernel: noapic, noacpi; alsa options: model, probe_mask, single_cmd, position_fix). No option was working.

But with "options snd-hda-intel enable_msi=1" set in /etc/modprobe.d/alsa-base (no other alsa option, no kernel option) I have success.

FilipK (filip-koczorowski) wrote :

I've tried the "options snd-hda-intel enable_msi=1" solution but still get no sound. I can however run sound preferences and hit "test" there to get a silent buzz in the speakers. Without "options snd-hda-intel enable_msi=1" the sound preferences window hangs when I click "test" with a message:
"audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink: Failed to connect stream: Invalid argument".

FilipK: Please ensure that all of your mixer controls are unmuted. I sometimes get the buzz you are describing when my volume is muted, but there as a program that is trying to output audio.

Thanks a lot, it also worked for me!

For me it worked too on my DV7-1070 on both 8.04 and 8.10.

Me and my friend is using hp dv4 (same model 1131tx) we were getting same problem. We tried "options snd-hda-intel enable_msi=1". It worked for him but not for me. he is using 64 bit ubuntu8.10, mine is 32 bit. it worked for me at first two boot but not after that. I am getting sound (ding ding) at login screen. after login into ubuntu. no sound application is running.
as noted by FilipK, I am getting same error at sound preferences while testing.

Note: when i boot ubutu in to failsafe mode everything works perfectly.

FilipK (filip-koczorowski) wrote :

Correction - the "options snd-hda-intel enable_msi=1" workaround works for me (Ubuntu 8.10, HP dv7-1080ew). Like umer suggested, I had one of the outputs muted in the mixer.

"options snd-hda-intel enable_msi=1" works for me on Ubuntu 8.10 and Lenovo ThinkPad W500.

Please note that the title of this "bug" is misleading: it is not related to HP laptops but more probably to the Intel sound card HDA 82801I (ICH9 Family).

Hello guys! I recently bought a HP Pavilion dv7 1070, and I face the same problem with sound!

Sorry for the stupid question (I am quite new to linux...), but... where exactly do I have to put the "options snd-hda-intel enable_msi=1"??? Do I have to edit "/etc/modprobe.d/alsa-base"?

Thanks a lot!!

lbitb (lothar-blaha) wrote :

Hello dionisis84,

Yes, you have to edit /etc/modprobe.d/alsa-base. I have written the line at the end of this file. Maybe it's helpful to read for further information.

dionisis84 (dionisis84) wrote :

Thanks a lot for the reply lbitb! I have another question! Is there a way to test the instructions using the Live CD, so I don't have to install Ubuntu first on my hard drive? Maybe restart alsa using a command or something like this??

Thanks again!

try sudo invoke-rc.d alsa-utils restart
which would be the same as sudo /etc/init.d/alsa-utils restart
this is on intrepid

I have similar problems with my Dell E6400. OSS works fine and ALSA appears to, but the sound that comes out the speakers is a bunch of closely spaced clicks, perhaps best described as what a candy wrapper sounds like when you crinkle it.

I tried the fix of modifying /etc/modprobe.d/alsa-base with the new options statement, but it didn't solve it for me. The E6400 also has the same sound card:

 lshw -c multimedia

We're closing bug 269586 because the original reporter provided enough information to figure out the problem, and his problem is now resolved.

However, a large number of users have a seemingly similar problem (poor quality sound that can be worked around by disabling ACPI in grub), and the noise has made this bug report unmanageable.

If you have sound, but it 'stutters' or 'strange' or otherwise, and the workaround of "options snd-hda-intel enable_msi=1" set in /etc/modprobe.d/alsa-base does *not* work, THEN YOU HAVE A DIFFERENT PROBLEM that unfortunately has similar symptoms.

Your next steps:

1) Try the posted resolution: "options snd-hda-intel enable_msi=1" set in /etc/modprobe.d/alsa-base . If it works, simply unsubscribe from the bug - do not post the fact of success. If you have a duplicate bug, please close it at the Launchpad website.

2) If it doesn't work, then please try the troubleshooting guide at . It really does solve many user sound issues.

3) If that doesn't work, try the other troubleshooting guide at . It also solves many, many problems.

4) If that doesn't work, then please obtain the information requested from the "Reporting Sound Bugs" section of , and add then to a new bug report as separate attachments. Please do not open a new report until you have the debugging information to add - without it, the report is not useful.

you added the line in which file to make sound work on thinkpad W500 ? because mine stopped suddenly too

have you tried this

Set "options snd-hda-intel enable_msi=1" in /etc/modprobe.d/alsa-base

I recently bought a HP DV7-1003EA, also suffering duff audio, jitter, echo type effect.

Looking at /proc/interrupts, I realised I wasn't getting any interrupts from the codec (cat /proc/asound/card0/codec#0 tells me it is an IDT 92HD71B7X), so I assumed it wasn't getting initialised properly. Not sure the snd-hda-intel driver knows what it is really, so went searching for a way to educate it.


   echo "options snd-hda-intel enable_msi=1" >> /etc/modprobe.d/alsa-base

into a root console and rebooting has done the trick. Thanks guys!

Yep, the enable_msi=1 option fails after resume from hibernate as Mbarak A. Bujra says above.

Also reported more recently here:


Herton Ronaldo Krzesinski has changelog comments:
  ALSA: hda - Add quirk for another HP dv7
  Enable MSI system wide for systems that need it to function properly (#44855).
  Add MSI quirk list for hda devices, to force enable_msi setting parameter when needed (#44855).

So I guess it's a matter of waiting for Ubuntu to update the kernel...
