When I run the command you suggested, a popping noise still occurs right when the device is opened. If I run that command in sequence with short interval (like 2 or 3 secs) between runs, I get no popping noise. When the interval is longer, I get the usual click immediately before the sound is played. This only happens when on battery. On AC power never happens.

Just for testing, I have installed Fedora 9 which also uses kernel 2.6.25. And the pop noise does not occur (either when on AC or on battery). I have even tried direct ALSA access and... no popping at all! ALso, to check if powersaved was enabling anything that could be interfering with the sound, I have disabled this service and rebooted. The problem remained... :-( -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

And strangely enough, this happens with all types of kernels: pae, default or even vanilla! This strange behaviour reminds me of the "no sound after Windows" issue reported by many users of HP DV2000 in this forum: http://ubuntuforums.org/showthread.php?t=455147&page=8 The difference is that, in their case, booting Windows created the problem. In my case, it creates a temporary fix for the problem... The following command returns 0 when on AC, and 10 when on battery: # cat /sys/module/snd_hda_intel/parameters/power_save But changing the value of this, doesn't eliminate the popping. And, BTW, who is daemon responsible for changing this value? I have stopped powersaved, but still this values get updated whenever I connect/disconnect the battery!... Note that I don't get this behaviour in Fedora 9: I can reboot Fedora 9 repeatedly, I get no popping noise. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This is hard to avoid. You may add power_controller=0 option to snd-hda-intel in /etc/modprobe.d/sound, which *might* suppress some noises, but not in many cases. I fail to find any default setting that adjusts this parameter in powersave, too.

Even with the current pm-utils package, creating a file

/etc/pm/config.d/sound (the name does not really matter), just containing

SOUND_PM=0

should fix this, at the expense of more power consumption when on battery.

I can confirm that this fixes the audio popping issue on my Compaq F572US laptop which experienced the same issue as the original post. ~~ Andrew D. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
