sound card doesn't work in Feisty Fawn

EDIT/PS: if anyone needs more info I'd be glad to post whatever is needed

I, too, am having trouble with sound. My sound device is a Realtek ALC850 chip on my ASUS A8N-E motherboard. Sound worked fine under Kubuntu 6.10. I installed Kubuntu 7.04 from the alternate CD. I tried to do an upgrade, but that didn't work, so I reformatted the root and the /usr partitions, and left the /home partition alone. After doing this, I could not log in, because the system didn't recognize me as a user, and I wasn't asked during the install to set up a user. I will report this as a separate bug, but it seems important to mention it here. After booting under the "rescue" mode from grub, I added a user, using the user name I had formerly used, since I had a user directory by that name in the /home directory. This led to a problem running sudo, which I fixed by deleting my old .kde directory and .kderc file. Maybe the sound issue is similar, and I need to delete some config file in my home directory??

Thanks for taking the time to report this bug and helping to make Ubuntu better. Could you please add the output requested at https://help.ubuntu.com/community/DebuggingSoundProblems ? Thanks in advance.

So I was just starting up the computer to send these to you, and I log in, and the login sound plays. Just fine. Like was never a problem before. My music and video sound works. It's like it just got over it. I'm so confused now (but also happy). Where do we go from here? Btw: don't just call me a newb and dismiss this as another case of someone just not restarting their computer and as soon as they did it works. I've started, shutdown and restarted my computer plenty and only just now has it started to work. I'm not that convinced it will keep working (though I am of course cautiously optimistic, and hoping that it will). But even if it is fine now, I want to know why it wasn't working, and why it suddenly was fine. I made no system changes, no updates, nothing between the time it wasn't working and now. </rambling> Please respond and tell me what the plan is now. Thank you.

Certain new HPs seem to exhibit these symptoms. It appears to be a hardware issue. Please contact your vendor; a tech should advise you whether to update the bios.

just an update, the sound went back to not working :-( I'll try contacting the techies as suggested above

So I contacted HP Support, and after the usual, we don't support linux dance, they ran me through updating the bios. It didn't help. The sound still isn't working

Fix committed in hg. You need to use model=laptop , i.e.,

echo options snd-hda-intel model=laptop|sudo tee -a /etc/modprobe.d/alsa-base

here is the output

echo options snd-hda-intel model=laptop|sudo tee -a /etc/modprobe.d /alsa-base
tee: /etc/modprobe.d: Is a directory
options snd-hda-intel model=laptop

The sound didn't work after doing the above, but yesterday the sound was working. I restarted it a few times. Still worked. Tried using the headphone jacks, those didn't work. Microphone jack, same thing, didn't work. But at least the speakers were working. Today they are back to not working. It's very frustrating.

I fixed my problem! I ran across a possible solution on the web, and it worked. My more refined diagnosis now is that a user must be a member of the "audio" group to have the sound turned on, and this is not done by default when the user is created. I had to install the "KUser" package, and use it to assign users to the "audio" group, and after exiting KDE and logging in again, the sound worked.

Hi VaebnKehn,

This bug report was marked "Fix Committed" a while ago but there hasn't been any recent activity. Can you just verify this bug has been resolved and we'll go ahead and mark this bug report as "Fix Released". Thanks in advance.

was that fix committed to the main release? cause I've updated and
I'm still experiencing the same issue (though it has gotten much
better, I would say that it hasn't been completely solved)

the sound only works when I start the laptop unplugged. When I start
the computer plugged in, it will sometimes work, but usually not.

Did you do as Daniel instructed as well:

echo options snd-hda-intel model=laptop|sudo tee -a /etc/modprobe.d/alsa-base

It looked like you had an extra space in "/etc/modprobe.d/alsa-base" which was causing problems when you ran the command. Thanks.

tee: /etc/modprobe.d: Is a directory
options snd-hda-intel model=laptop

is what it output

HI VaebnKehn,

Sorry for the delayed response. You are getting that error because you are typing the command incorrectly. It seems you are incorrectly using:

echo options snd-hda-intel model=laptop|sudo tee -a /etc/modprobe.d/ alsa-base

You cannot have a space in "/etc/modprobe.d/ alsa-base" . It needs to be:

echo options snd-hda-intel model=laptop|sudo tee -a /etc/modprobe.d/alsa-base

Thanks VaebnKehn. I'll go ahead and mark this Fix Released per the email you had sent me which I'll post below:

"lol, seven months xD

holy long response time batman!

well, the problem resolved itself with normal updates, so whatever the problem was, it is no longer

thank you for following up on this though, from every ubuntu user: thanks"
