SUSE :: Loud Popping Sound When On Battery Power Only
Mar 10, 2010
Loud popping sound approx. 11 secs after switching to battery power if audio hasnt been used for awhile (11 secs probably?) It will pop when audio is started (like movie, alert etc etc). It appears to be a power saving problem. And is not occurring for me on other distros, and only started happening recently on OpenSuSE. I found the exact same problem on the OpenSuSE forums dated 2008 (see: [URL]) but no solution as of yet. And by loud popping sound imagine one of those 'black cat' snappers you throw on the ground and they pop, it sounds almost identical.

I have a Creative Labs SB X-Fi sound card and I am getting a lot of crackling & popping with it. Plus I have to kill and restart pulseaudio a lot. Does anyone know of anything that can be done to help this out? I have the latest F12 kernel and rpms installed.

Since I installed Natty recently, I had this "popping" sound from the speakers when the laptop was running on battery. Turns out this popping has to do with a power-saving feature for "hda-intel" sound-chips.
Open terminal and do:
Code:
gksudo gedit /usr/lib/pm-utils/power.d/intel-audio-powersave
Find this line:
INTEL_AUDIO_POWERSAVE=${INTEL_AUDIO_POWERSAVE:-true}
And comment it out by putting a "#" in front of it like this:
# INTEL_AUDIO_POWERSAVE=${INTEL_AUDIO_POWERSAVE:-true}
Just below this line you make a new line, like this:
INTEL_AUDIO_POWERSAVE=false
So now you will have:
# INTEL_AUDIO_POWERSAVE=${INTEL_AUDIO_POWERSAVE:-true}
INTEL_AUDIO_POWERSAVE=false
Save the file (File > Save) and exit.
Reboot the computer.
The popping sound will be gone.
If you for some reason need to undo the setting, just open the file again and remove the "#" from:
INTEL_AUDIO_POWERSAVE=${INTEL_AUDIO_POWERSAVE:-true}
And delete this line:
INTEL_AUDIO_POWERSAVE=false
Save the file.
Reboot.

Since yesterday I have a weird problem: sounds is way too loud. In gmixer, it starts at 485% and goes up to 65535%. I don't think I change anything in the settings which can explain that.

I did a clean install to 10.04. Not too many issues except any sound I play sounds like it's underwater and pops while playing. I have tried to do the Pulse Audio install, but every time I loaded pauvcontrol (I think was the title), it would pop up "Connection Failure: Connection Refused." I tried to follow other guides, but they'd all fail because I'd be missing half of the files it changed. I have a Creative Labs X-Fi Fatality card that has given me troubles in the past, but usually, it works. I tried to install Creative's open driver, but again, I had an error when I attempted to Make the directory.

so, i just recently installed ubuntu and i tried to go watch a videos video and i noticed my speakers weren't working. then i raised the volume from mute to "1", no sound, then to "2", again no sound. then i went to "3" and the sound came on but it was ridiculously loud. it does this with all sounds from my computer, the first 2 notches don't emit any sound but the third and above emit sound at a very high level. running a dell precision m90 notebook. never had a problem when running my windows 7 boot, only my ubuntu boot.

I recently installed Ubuntu 9.10 on my desktop and I now remember why I didn't ever use it, and that is because the sound volumes are ear-shattering loud across reboots. I have tried doing:Code:sudo alsactl store 0However it doesn't save the settings. I can set the volumes manually using alsa-mixer but that is a pain.I have read the "comprehensive fix to audio problems"sticky but it did not alleviate my problem. And as far as I know, my alsa is up to date.I'm sorry I don't know the relevant output of code needed to show alsa version, etc., so please inform me and I will post accordingly.

I have a laptop DELL Latitude D600. The sounds works great and I can control it with the laptop buttons (increase/decrease/mute volume).
I just upgraded to Ubuntu 10.04. In prior versions, I could control independently the volume for the speakers and for the headphones. And I was able to "join" them together so that when I increase the volume, it increases in both.
Now in 10.04 I can't find where to join them. But that's fine. The problem I have now is that the volume for the headphones seems to be a 10x multiplier of the "master" volume. For example, in order to hear "normal" on the headphones, the master volume has to be almost on mute. If I increase to 1/4 of the way out, the sound is too loud for a human being.
I went to alsamixer to see what's going on and started with everything at 0.
So I put my mouse on top of the volume control on the taskbar and with one "click" on the wheel (to increase volume) I get this code...
That's just one 'click' of the wheel... and the volume control shows almost nothing on the volume bar (the tooltip says Output: 5% -75.70 dB.
In the past the 5% gain in the output was proportional for the headphones. But now it's multiplied by a lot. This makes the volume control useless when using headphones. I have to go to alsamixer to adjust manually.
And to top it off, the new Ubuntu doesn't have the "old" volume control where you can see the level of each output element.

Basically every time I boot into Ubuntu any sound will be vary loud until I move the volume slider, it doesn't matter how much I move the slider as long as it moves then all sound will play at the normal volume and volume control works like it's suppose too until I reboot. This problem started in 9.10 and still happens in 10.04 and 10.10(as of a couple days ago).As far as I can tell the issue only exists in Ubuntu, doesn't happen in Fedora(Gnome), OpenSuSE(KDE) or Kubuntu.Running 10.04.1 32-bit, Logitech Clear Chat USB Headset, don't have any speakers.

I am using Fedora 12. Prior to this I was using Ubuntu 9.10. In Fedora 12, I am facing a problem with battery power. Sometimes when it is fully charged I remove the power cord, battery power comes down to 40%-41%. It never happened with Ubuntu, which gave quite a good battery performance. My question is when it is showing Laptop Battery 100% i.e. fully charged, if I remove the cord why it comes down to 40%-41% (and always in this range).

I am running a cli only based laptop for a special project; however, is there any terminal based simple text or GUI applications that will give me power remaining and other information about the battery? Looking for: power remaining, total power, WATTS, AMPS, etc.just the basic items and some other items, nothing to fancy.

I have a starling netbook, but I have the regular ubuntu interface on it. I normally have it plugged into a power source, but now it is unplugged. As I remember, at one time there was an icon on the top bar that showed you how much battery life you have left, but now I don't see it. How do I get info on the percent of power I have left?

I know how to set and have set my net-book gz5 running on lucid to stay on at all times.however unlike in xubuntu I don't have the option to change when the computer is critically low. I don't have the room to install xubuntu with my preferred gnome desktop wondered if anyone out thee knows where if there is a .config file that I can dictate the percentage of battery life before being considered critically low. ei now it seems to consider itself low at 15% which robs me of about 2 hours of usage id like to set it around 1%

based distros but never tried it in others. I am wondering if I can complete this guide in Fedora 15. In order for Linux to be my primary OS (Which I'd really like it to be) I need to be able to see how much battery power I have. If all the packages are available how I can download them and what not so that I can get my battery power back up.
Here it is: [URL]

I'm running 11.04 on my Dell SXPS 1645. Today I unplugged my laptop from AC power a few times and after about 10 minutes, Ubuntu would hang, not responding to anything. Frozen mouse, frozen keys. The ONLY thing I could do to get it out was to do a hard hardware restart by holding down the power button.
It happened twice on Skype (and I thought it was just the buggy 2.2 beta that was hanging my beautiful OS), once while installing a printer, and once while I was just futzin around on firefox.

I am running 10.04 on an Acer Aspire One
Since my upgrade from Lucid my battery icon displays permanent full charge even when running without AC power. When the battery runs out, this leads to an immediate violent shut down, everything dies at once.
My power management settings for running on battery are as follows;
1 hour
Blank Screen
Hibernate
Yes
10 MIns
Yes

I've got a problem with my laptop and I finally decided to try to solve it. My computer sometimes (not everytime) freezes. It's just when I'm using battery power. I figured out that this is not connected with some specific action (e.g. some app crash), it can freeze 1 minute after start or 10 minutes, I think it's random. I've checked my /var/log/messages.log file and these are the last messages before freeze (exactly at 9:16:15):
Code:

I'm running the latest slackware64-current on my Dell laptop (Inspiron 1420). I rarely run it on battery power, so I don't know when this behavior started, but now it seems when I'm on battery power the hard drive likes to spin down and then spin up. This is not after 5 minutes or so of inactivity. This is 30 seconds of inactivity because I'm reading a web page or something. There is a noticable delay in the response of the system as a whole when the drive is having to spin back up. I'm also using xfce-4.6.2 with the xfce power manager. I've checked the settings, and I don't see anything about spinning down the hard drives. I've also looked through some ACPI rules, but I'm coming up empty.

Fresh new installation of squeeze on an MSI Wind U100 netbook.Everything works fine, except resuming from hibernate when on battery power. The netbook starts loading the hibernate info after grub booting, then the screen goes blank and the netbook reboots.The unusual thing is that resuming from hibernate works when on AC power.Could not find anything interesting in /var/log/messages

How does the Battery Power Meter works.As I know that the APCI is control by software.so my question is the battery connected also to other place on the board and send signal for how much power left.or every motherboard that have APCI "Enabled" can recognize only from the DC power connector how much left. if yes, in what why it recognized.

I recently bought a 12-cell (extended-life) battery for my HP dv8000 AMD Turion64 laptop. While the extra battery life is spectacular, the machine is virtually unusable when not plugged in. Either the hardware or the OS (I'm not sure which) seems to view each of the 12 cells as a separate battery, so whenever a cell nears depletion and the machine prepares to transition to the next cell, the computer slows to a standstill, as though it were shifting into an extreme version of Powersave mode. This can last for several minutes at a time, during which period all I can do is stare helplessly at my screen.
I have all but disabled Powersave features in the Power Management applet, setting the laptop to Performance mode on both AC and battery power, with Powersave only kicking in below 10%. So that isn't the source of the problem. I have also disabled Compositing and all desktop effects, except the mouse pointer application-icon animations that appear when I open an application, which I can't figure out how to disable. All this to no avail.
Plug the machine back in and it zips along at a merry Linux pace. I don't want to keep it plugged in all the time, though, because a) this is a laptop and therefore should be mobile; and b) keeping a charged battery plugged in drastically shortens its battery life. Besides, this is a brand-new battery; it should still be working fine.

I am having several problems with what i believe to be gnome-power-management. Power management will randomly say that either i do, or don't have a battery. This means that the icon in the notification area does not appear, and I can not access the settings for on battery power. also, when i tell Ubuntu to suspend, it just goes to the screensaver and nothing happens. conky is still able to read the battery just fine, its power management thats having problems.

I'm having a huge performance decrease when I'm on Battery Power. Plugged in this thing runs AMAZING, HDMI with HD video, I can run compiz 3d, full desktop advanced effects, HD video from ....., you name it. Just when I pull the cable out it slows down. I tried disabling ATI powerplay but that didnt help.
Is there a way I can toggle the performance, so that I can get "plugged in level performance" even when i'm on battery power? I'm not too bothered about how long the battery lasts. I'm usually always near an outlet.
