Intel HDA (Azalia) - strange popping sound

English Hardware
1

I’ve bought few days ago HP Pavilion dv-1133cl. I’ve installed OpenSuSE 11.1 with -pae kernel on it. From start I had no sound, but I managed finally to got it by following some topics on this forum and OpenSuSE’s wiki page concerning Alsa update.

Now the problem… Every single time I log into KDE3, when I play music/video, after I finish playing music/video and closing application(s), during shutdown process - I can hear popping sound (just for one second). I guess it can’t hurt, but it is quite annoying and in the end - quite strange when you count in that sound works just fine.

Here are some information:

Thank you very much for your help!

I’ve never been good at sorting those sorts of problems. If it were me, and I had that problem and wanted to sort it, I would write a bug report to try and get the attention of an alsa dev:
Submitting Bug Reports - openSUSE

Thank you for your answer, but first I would like to try to solve this problem before reporting bug.

I’ve borrowed Ubuntu CD (8.10) from a friend, just to check how sound works on it (in live environment. It was configured properly, no popping sound except on power off (just for a millisecond). It is quite obvious that something is wrong with configuration on my OpenSuSE installation.

Maybe it is important to notice - I’ve installed OpenSuSE from DVD, but using minimal Text installation. Then I pulled down “by hand” (using zypper of course) rest of the system (KDE, alsa, Ooo, Gimp, Inkscape, NetworkManager etc.) from the DVD and repositories. I configured sound by hand using alsaconf. I see myself as experienced user, I am using Linux for more than 6 years, used Slackware for 4 years, but I don’t know much about sound in Linux. Simply, alsaconf; alsamixer; alsactl store was working just fine for these years.

The first thing that bothers me is “two” sound cards. If you check the output of lspci commmand there are two audio devices. The same was in alsaconf dialog:

  • hda-intel - Ati Technologies Inc SBx00 Azalia (Intel HDA)
  • hda-intel - Ati Technologies Inc RS780 Azalia controller

I edited /etc/modprobe.d/sound and now it looks like this:


options snd slots=snd-hda-intel,snd-hda-intel
alias snd-card-0 snd-hda-intel
alias snd-card-1 snd-hda-intel

The problem is that now popping sound is not constant - sometimes it is present and sometimes not.

i have the same problem
i did not have this problem in SLED9 and SLED10
seemed like SLED10sp1 or 2 is when it came about
SLED11 is the same way.

when you first boot up it might be normal, you can play everything fine ,etc and then it starts popping and will not stop until you reboot or mute it , other sounds can be heard from applications , media etc while the popping is happening

might be the laptop is getting to hot… thats what is seems like to me when i get the popping sound. I boot up and it is fine,
it gets hot over time and starts popping

not sure if you have a similar finding

SLED11 / Compaq/HP business 8710w laptop
