[SOLVED] Sound problems-Intel 8201I (ICH9 Family) HD Audio

[WheelsOfSteel]

Same here, let's hope this works out of the box with Intrepid final, it doesn't work at all with Intrepid Beta though

Yes, screwed my ubuntu upgrading to intrepid today. No wired network on my pavilion dv7. Re-installed Hardy and will stay at Hardy until Intrepid is seasoned at least.
I'll have to live with the cpu issue for now.

If anyone knows how to fix the sound and load 2 cores then please let us know.

The pci=noacpi fixes the sound, but also makes the system boot with only 1 cpu core if running dual core cpu's like me - centrino 2.

Same here.

Hey,
I think I may have found a solution. Try adding pci=noacpi as a boot option. That solved it for me on my 32bit install, however I had done a whole bunch of other stuff before hand, so I don't know if the boot option alone is enough, or what else needs to be done. I'm going to do a clean install with Hardy 64bit and then see what is neccessary to get this working properly. I'll let you know what I find.

Have a HP DV4-1041TX notebook, your fix fixed my problem, sound could be better but at least it works now, thanks

I'm on an asus x71a. Tried the pci=noacpi, unfortunately, no luck.

Also followed instructions in this thread (about specific options to snd-hda-intel) but still.. no sound at all.
If there are other options to try, pls let me know.

We have different Audio Codecs, but something that may work for you is using the "irqpoll" kernel option. This fixed my sound issues in Intrepid which could not be worked around using the pci=noacpi option, however, irqpoll does cause the touchpad to be a little less responsive.

Alright folks, good news! The audio situation is solved for anyone using the IDT 92HD71B7X audio codec. Comes in most HP dv4, dv5, and dv7 laptops. The solution as found here:
https://bugs.launchpad.net/ubuntu/+bug/269586

The solution is quite simply.
First:

gksu gedit /etc/modprobe.d/alsa-base

Then add the following to the end of the file:

options snd-hda-intel enable_msi=1

For me this worked on a clean install of Intrepid. Also, make sure you remove any kernel options you put in place to get sound working previously, such as noacpi, pci=noacpi, or irqpoll.
Since two of those reduce you down to one core, and the last one screws around with trackpad response.

The above mentioned solution seems to fix all my flaws, and now I seem to have everything I need working on my dv4.

Hope this helped most people.

Thanks remu!!! it really solved the sound problem of my Compaq CQ-45 IDT High Definition Audio Codec...

Having trouble with a DV7, and have tried just about everything listed, including the SOLVED fix here. The welcome sound plays normally when starting, but after that nothing, and some error messages when changing settings. Using the latest Intrepid, but I couldn't get it to work under Hardy either.

Update:
Disabling Skype and setting all the drop downs in the sound cp to Pulse has sound working normally. No dice in Skype, but other than that things appear to be working normally.

Thankyou SOOOO much remu! That has fixed all of my audio issues on a HP dv7 laptop!
You Rock!

[Jorge_C]

Thank you very much remu!!

Sound works now, but I have a small issue when muting pcm channel (which controls both the speakers and the headphones) while a sound is being played: the speakers/headphones start making some weird noises. Muting front or headphones or master channel works fine, though. However, I don't want my volume and mute keys to control master channel since it is way too sensitive and a small change makes the sound much higher or lower.

Any ideas about how to stop this small problem?
