Fedora 12: Annoying hiss from laptop speakers

[loren456]

I just installed Fedora 12 on my Toshiba laptop and ran into the same problem I had with Fedora 11, only this time it remains unresolvable: an unstoppable hiss coming from the built-in speakers. I tried the Pulseaudio fixed and workarounds, but alas, no joy. Not to be a complainer (because I *am* humbly asking for help, here) but at this stage of development I would think something like sound would be firmly and irrevocably resolved, and not require workarounds. Anyway, if someone can help me or point me to a previous post (yes, I've searched already) with the solution I would be most appreciative. Thanks.

I had a somewhat related issue on my desktop with the speakers, though there was a bit of a 'thunk thunk' noise along with the hiss. It turned out it was my router with wireless enabled was too close to the speakers. I repositioned the speakers and router a bit, and now all is quiet when it should be quiet.

That may have some bearing on your issue - some of the info. I found when I was researching was from folks who talked about wireless phones near their computer causing random speaker noises. So if you have some sort of wireless device or phone in the proximity of your laptop (speakers), move it away and see if it makes a difference.

I have the same issue with my laptop speakers. This only happens with my Fedora 12 installation. I don't get this issue when I use Ubuntu 8.04.

Could this have something to do with power-save settings? My audio device seems to go into crackle-hiss mode after a brief period of inactivity.

Here's the relevant information about my audio device from lspci.

00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)

It was an issue caused by power management. I followed instructions on this page and I don't get the hissing and popping noises anymore!

Here are the instructions from the page.

1. If you hear a clicking noise, see this link: https://fedoraproject.org/wiki/Commo...ugs#hda-clicks
2. Disable power management for audio by running this as one long line, and then reload the module, or reboot. This may reduce the amount of popping noises. (This will ask for root's password.)
   
   

   su -c 'echo "options snd_hda_intel power_save=0" > /etc/modprobe.d/snd_hda_intel.conf'

3. Reboot to Test and verify if the problem is resolved.
