CPU load / sound output

today i noticed that the cpu load goes up to 15% from 2% (in itunes) when i switch the sound output from line out to the integrated speakers! can anyone confirm this? this seems to be a systemwide issue because it happens with QT and VLC (mp3 playback only) too!

I've tried it, nothing. Everything stays @2-3% while switching back and forth. So it doesn't seem like it makes a difference. I have noticed though, the CPU sitting around 40% for a few minutes without having applications open, especially after I wake the computer from sleep.
Also, I'm assuming you're using OS X, and this is where I tried this.

No Sound Output but Still Loaded

Hi guys, this is my first journey with Arch Linux and this introduction process has been fairly trouble-free with the exception of getting my sound system working.
Right now I'm running a Macbook Pro 6,2 (Mid 2010) with two audio devices: 1) an Intel integrated card(labeled=MID) and 2) a Nvidia HDMI card(label=NVidia). Since I'm not using any HDMI outputs, I'm trying to get the Intel card to output sound but it seems like nothing I do is working. I've combed through both the wiki pages on ALSA and the Macbook#Sound configuration section but so far, it's a no-go. According to /dev/snd, the sound modules are indeed loaded. "speaker-test" has no problem running but there's no sound output. I've tried muting and playing around with volume levels in alsamixer. Right now, I'm guessing that I might have missed something with my .asoundrc? I'm not entirely sure.
Here's all the relevant information...forgive me if I missed anything.

If someone could lend a hand, I'd greatly appreciate. I know that it can get working since it was working out of the box flawlessly on an Archbang install but I wanted to do things the right way, The Arch Way, this time around.

Hi
I have a similar setup with AMD/ATI devices. Try to set the order of the soundcards (Alsa#Set_the_default_sound_card): Look up your "vid" and "pid" values with "lspci -nn" and change the /etc/modprobe.d/alsa-base.conf to:
# SB [HDA ATI SB]
options snd-hda-intel index=0 model=auto vid=1002 pid=1308
# HDMI [HDA ATI HDMI]
options snd-hda-intel index=1 model=auto vid=1022 pid=780d
...or something like that. After that my soundcard worked but the sound quality was poor (no bass).
Hope this helps.

How do you spread CPU load over more cores?

Hi
I recently bought a macbook pro quadcore i7 because my 2007 macbook couldn't cope with the demands of Logic when using it rewired with Ableton Live, and had lots of CPU overload messages.
I am really disappointed that having spent so much money to overcome this problem, it has only slightly improved the amount of overload messages. I read the article below about how to spread CPU power over the cores, now I have 8. I still can't figure out though how to control which channels are using which core and spreading the CPU load to cores 5-8 which don't seem to be being used. Any ideas?
Can I rewire from ableton to different cores?
In my project, the 2nd core keeps overloading whilst the others are down. Is it to do with aux channels, master channels, buses etc?
Or should I upload my memory to 8GB RAM?
Thanks
Steve
Here's the article:
About core activity
Logic breaks tasks down into threads that can be assigned to a single core for execution. It's not possible to split a single thread across multiple cores, although a single core may run multiple threads at the same time. This is one reason that you may sometimes see uneven load distributions across the available cores on your computer. If one thread is very processor-intensive, the core running that thread may show much more activity than the cores running less demanding tasks. This is the main reason that you may get "Core Audio Overload" warning messages even though some of the cores on your system may not show significant activity.
To monitor Logic as it uses the cores on your system, double-click the CPU meter in the Transport area.
A window displays a meter for each core.
The same concept applies to channel strips as well. Each channel strip—and all plug-ins it contains—is processed by one core. If you are using many processor-intensive plug-ins on a single channel strip, the core running it may show heavier activity. This is especially true if you are working at high sample rates (88.2 kHz or higher).
Redistributing core loads
If you find that a single core has much higher activity, use these strategies to redistribute the load.
In the example below, there is a single Software Instrument channel strip with plug-ins routed directly to Output 1-2. The channel strip for Output 1-2 has a large number of plug-ins.
In this example there is activity on two cores: the left core is handling the Software Instrument while the next core processes the Output 1-2 channel strip. You can use routing capabilities in Logic to distribute the load to more cores without changing the sound, as in the next image.
The resulting signal chain is Inst 1 > Aux 1 > Aux 2 > Out 1-2, as shown in this table:
Channel strip
Input
Output
Inst 1
Bus 1
Aux 1
Bus 1
Bus 2
Aux 2
Bus 2
Out 1-2
Also, the first four plug-ins have moved from Output 1-2 to Aux 1 and the remaining four plug-ins to Aux 2.
After adjusting the volumes to the respective channel strips appropriately, the result sounds identical, but now the load is distributed among four cores instead of two. You can use this concept to redistribute plug-ins from Audio channel strips, Software Instruments, Auxes, and Outputs (as in this example).
In the image above, there is still a very heavy load on a single core, even though it's using the routing described above. Notice the Inst 1 channel strip is selected. When a Software Instrument track is selected in the Arrange window, Logic enters "Live Input Mode". In this mode, Logic turns on every plug-in in the channel strip's signal path so the channel strip can be played live from a MIDI controller. All of this must be handled by a single thread and therefore just one core. It's a good idea to keep a track that uses an Audio channel strip selected in the Arrange window, unless you're actively playing or recording to a Software Instrument.

OS X Snow Leopard introduced Grand Central, where the OS will distribute the load better to more cores, however it takes time for software to adapt to these changes and make a rewrite of the codebase and test it out, Apple's included.

Can not change sound output. Help Please

Well, i've been digging all the forums lately in web. my problem is, i can't change my 'system' sound output to my sound card which is Native Instruments Audio8 Dj.
Let me explain my problem decently. I do the usual procedure, system preferences > sound > n then select the output. but nothing happens. it is always set on internal speakers or headphone or whatever plugged in to the *Built-in Output*. I try switching from audio-midi setup n that doesn't work as well. The system perfectly recognizes the sound card, i can get output from sound card with applications which have their own output settings. But i cant change the system output. I have the latest version of soundflower loaded(this might be causing the problem who knows), i used many soundcards before(or maybe even ex-drivers?) n they used to work until i updated to snow leopard. I also tried trashing the files in macintosh hd > library > preferences > audio >>
and those files *did not regenerate* after restart(like 10 times), so i had to copy them from my imac.(hehe). i tried resetting pram or nvram.(didn't do any good too)And also i tried trashing soundpref.plist which didn't do me any good neither. Now i need that sound card to give me my system output. I don't need drivers of any other ex-sound cards or whatever. My drivers are up to date. And im pretty sure this ain't an hardware fail.
So, any ideas? Thx.

I am having the exact same problem. I have spoken with Apple Care and they are having my case reviewed by "Engineers," apparently. Its very frustrating as I cannot listen to iTunes or any of my video games through my really nice monitor speakers. FYI, I had this problem without installing Sound Flower, since then I have installed it in the hopes that having something different to select it might work but no changes. If I hear any good news from Apple I will be back to let you know. This seems to be a very rare problem as I have only found one other post about this issue.

High CPU load on SUP720-3BXL / C6k

Hi,
I know it has been discussed many times before, but may I get some new inspiration to solve some problems here.
We've some c6509 with SUP720-3BXL. One of routers has a WS-X6704-10G module with DFC. This is the only card installed besides the SUP720. We're run into some heavy CPU problems regarding the RP:

Hi Rajeev,
we have temporary disabled Netflow after we ran into a flapping BGP session problem one hour ago. Router killed BGP related processes due to no free CPU time.
After disabling Netflow, the load of the RP has been decreased dramaticly from <80% to ~30%. But we can't disable Netflow at all because we need the flows to get information for our DDoS protection.
We have now increased CPU ressources for processes:
(no scheduler max-task-time)
scheduler allocate 10000 4000
CPU load is (very) high again:

I can get video on airplay anytime but i cannot get audio all the time. in sound output i select airplay but it only reverts back to internal speakers. same if i try earbuds. the only way to fix it is to restart computer. what do i do to fix it,

In case anyone has had the same problem as me, I have just managed to fix this by doing the following:
Switch off Mac
Switch back on in Safe Mode (Hit power button, then hold Shift key until a loading bar appears at the bottom of the screen).
Switch off Mac again
Remove power cord and wait 15 seconds
Plug power cord back in and hold down the keys alt, cmd, p, r all at the same time until you hear Starting chime for a second time and hopefully your audio will back.

[Solved] Compiz eats up ~20% CPU load in idle after recent update

Today I noticed that Compiz eats up 10-30% of CPU load resulting in the CPU clock often go up to maximum. It might be related with the recent updates but it's not sure - maybe the problem appeared earlier and I just didn't notice it. Restarting Compiz doesn't help, restarting the whole system neither.

Having problems choosing sound output through HDMI to my television, any one any ideas?

Though listed in the sounds options, I can't seem to choose a sound output to my TV through HDMI. I have sound output to headphones via the headphone socket or usb, but when I highlight to the HDMI TV option it justs returns to the top of the list, any ideas anyone?

About alsa dmix, and for the record:
On an Intel(R) Core(TM)2 Duo CPU E7500 @ 2.93GHz, the following are my finding about
quality/cpu when mixing two streams at 44khz:
a snippet from my .asoundrc
#converter "samplerate_best" # perfect: 16%cpu, maybe overkill
#converter "samplerate_medium" # almost perfect: 6%cpu
#converter "samplerate" # good: 4%cpu, definitely usable
#converter "samplerate_linear" # bad: 2%cpu, way better than default wine resampler
#converter "samplerate_order" # very bad: 2%cpu, like the default wine resampler
Here is the reference topic: https://bbs.archlinux.org/viewtopic.php?pid=942724
I may be wrong, but in an opensource world (code reusing), i really doubt pulseaudio could lead to better quality/cpuuse tradeoff.
Pulseaudio, being just another layer atop of alsa, could only lead to higher cpu usage.

CPU Load

I have checking out some minor cpu issues on one of my cat 2950's. I've
searched the documentation and cco but can't find the definition of the process
anyone can tell me what's mean of proce and is too high cpu load ?
20 686486772 157608074 4355 9.07% 9.49% 9.70% 0 Calhoun LED

If you have Cisco support, you can go here:
https://www.cisco.com/cgi-bin/Support/OutputInterpreter/home.pl
and enter the output results from the command you ran, that should give you an indication whether your percentages are good or not.

Fan RPM (rounds per minute) based on CPU load

I did some small testings regarding when the fan's are starting. I'm experiencing the following:
When running 3 times: yes > /dev/null the fans start to spin up after 1 minute full CPU load. They keep running till i kill those 3 processes. After 10 minutes full load the notebook is getting less hot because the fans are running at a good speed.
What they should do is write a component in osx that will measure the temperature and based on that information let the fans run...
With the current system the load is increasing all the time because you use it.. if the fans would start when its getting hotter the increasing temperature would stop and the case temp would be stable.
Therefor i dont think bringing in your laptop will help. I think they should be able to fix the problem thru software. Just like the whine issue... just the wrong amount of voltage are send thru the cpu.
The problem is... apple doesnt confirm this.. i hope OSX 1.4.7 will have such a tooling within it.
What do you think?

My completely unscientific experiences with my own MBP seems to support this, and I do believe that it begun happening after the last SMC update. I also believe that heat does in fact have an effect on the fans, but it is additive and that is why you mostly experience the fan activity generated by the CPU load.
I can hear my fans quite clearly on low RPM because of a strange, plastic whirring sound (oddly enough, they become more quiet on higher RPMs).

Gdm is running dbus-deamon with 100% CPU load

Hello Guys,
I have installed an Arch with Gnome yesterday (I am comming from Fedora). I am very happy with my installation, nearly everything works fine. Now i noticed, that my CPU load is super high. So i used top to check whats going on...
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
536 gdm 20 0 13108 1380 1136 R 100 0.0 126:25.88 /usr/bin/dbus-daemon --config-file=/etc/at-spi2/accessibility.conf --nofork --print-address 3
So gdm runs the dbus-daemon with 100% load. Whats goin on here? I have checked the wiki/forum and could not find anything.
Thx for help!
Some notes:
DAEMONS=(dbus networkmanager hwclock syslog-ng netfs crond)
gdm is started by systemd.
UPDATE
Hmm, seems to be a bug in dbus... The web is full of reports.

From the sound side try enabling and disabling msi for snd-hda-intel module (4 combinations to test). Another bothersome parameter is often snoop. Look for quirks for your hardware in alsa source code. Also you might want to disable your ~/.asoundrc for the time being. If you want to set MID as default card, you can use the recommended modprobe method in the meantime.
I would test another browser first though.

Sound outputting problem

Hi All,
I am having continuous problem solving the following sound issue:
When burnt both video and audio files, having used Compressor and Toast Titanium 9, the video plays fine however my sound plays only in two channels.
The sound was designed and edited in Soundtrack pro application. The output setting selected in Compressor is: 5.1 Surround Quicktime, 96.000 kHz.
There is also this warning box coming up, when changing the sequence setting audio output to surround, saying:
' The current audio device does not support the number of outputs set in the sequence settings audio outputs tab.'
Any help/advice will highly be appreciated.
Stephen

Hi Stephen,
First, I'm assuming you are using the optical out of your mac to go to the BDV. With it plugged into your mac goto your system prefs and in the Sound>Output>Devices select Line Out Digital.
In FCP goto Audio Video Settings>A/V Devices>Playback Output>Audio and select 'Built-in Output'. Now click the options button next to the selector. Set number of Channels to 6 and sample rate to 96000.
Now goto your sequence settings (Cmd-0) and under the Audio Outputs Tab click the selector that says 'Load Audio Output Preset' and select 5.1 and click OK
Back on the timeline right/ctrl-click the lock symbol on each track from 3-6 and select the following:
3: 3 (Ctr)
4: 4 (Sub)
5: 5&6 (rear L)
6: 5&6 (rear R)
1 and 2 will already be setup for Front L&R
That's it for FCP 5.1 support
In Toast you must set the audio output to Dolby Digital. PCM only supports Stereo on Bluray and DVDs. Just customize the settings in Toast. Click the customize button, then under encoding select Custom and choose Dobly Digital under Audio.
That should be you good to go
All the best
Pi

High CPU Load with Alesis Multimix Usb 2.0 mixer

Hi everybody,
i'm still playing around with logic studio 9, mainly mainstage 2.1.1 for a possible future live use.
Today i tried to use my Alesis Multimix 8 usb2.0, just as the output devices, using software instruments with a m-audio keystation.
I always get cpu peak load when playing notes, with every patch, either internal apple instrument or third party au instruments, when idle cpu load goes to about 40%...
If i revert back to internal output / internal input, cpu load drastically goes down to 10% idle and max 50-60% with internal instruments,max 80% with 2-3 layers of third party au instruments (Omnisphere, loungelizard, m-tron)...
I know that Alesis mac drivers for snow leopard are at a beta stage, but am i the only one experiencing this or is it a known problem?
Thanks,
Alex.

Hi Pan,
i made a different test today...
I know it's not the same but i tried using a guitar rig on mainstage (guitar on channel1 in the mixer), and even with 256 samples i ALWAYS get 100% cpu usage...
then closed mainstage and opened NI Guitar Rig 3 as standalone, using the alesis as interface, with 64 samples as buffer, i cannot go over 13-14% of CPU usage (Hi quality enabled)... I know that mainstage adds more effects than the ones i selected in guitar rig 3, but the HUGE difference in cpu usage cannot be just that, i mean...
It could be if one of the effects Mainstage was using is Space Designer.
If it is using Space Designer try using a lesser reverb, like Gold.
USB doesn't use that much more CPU so that's not the problem.
You are comparing two separate guitar setups, correct? Or do you mean you're opening Guitar Rig 3 in Mainstage?
pancenter-
As I understand it you are opening completely different setups, correct.

High MySQL CPU Load

Hello All,
I am currently running the following:
OS X Server 10.5.5
2x3GHz Multi-Core Xserve
8GBs RAM
MySQL Server v5.0.67
One problem I am having is that when someone does a MySQL database search on a particular webpage the CPU load can get upwards to 400% render the search useless to all other clients. The MySQL CPU load is getting so high that no one can then do a search and the results never come back until the other queries are finished first.
Why won't MySQL use the 8GBs of memory I have installed instead of sucking up CPU? Is there a way to allocate this in the OS or terminal? If not, should I be optimizing MySQL settings instead to better work with my query statement and 8GBs of memory that I have installed? I'm not exactly sure what to adjust within the MySQL settings if this is the case.
Any help would be greatly appreciated!
Thank you very much!

@Camelot,
I have not configured anything, everything is default install. I have about 6 devs on this box at all times and we do not have a MySQL admin. I really need to fine tune this setup as the DBs are starting to grow very big. I am looking for any help at this point and want to start fixing this now before it becomes more of a problem. I am going to start researching the MySQL dev zone ASAP.

X-Fi + 2 GFX-Cards = high CPU-Load, slow Mouse, hanging system

>X-Fi + 2 GFX-Cards = high CPU-Load, slow Mouse, hanging systemA Hey guys,
I'm running 2 GF 8800 GTs (PCIe .) cards on a MSI Eclipse SLI board. My Audigy2 ZS PCI runned fine in this system.
I just replaced the Audigy by a PCIe X-Fi (EMU20K2 audio processor - not the xtreme audio from MSI).
Now I'm dealing with the following issue:
- System startup is slow
- in Windows, Mouse is slow, stuttering
- high CPU-Load
- very slow system response
!!! Attention !!! I had this problems allready at the st boot with the X-Fi, when the driver from creative wasn't installed (the card was recognized as "HD Audio" bei Windows 7). Installing the drivers didn't help.
If I install only one graphics card, the system runns fine and I can use the X-Fi and it's Software without problems.
If I replace the X-Fi by the PCIe Xtreme Audio from MSI, System runns fine.
If I use Win XP with the two GFX cards and the X-Fi, System runns fine.
Can you help me?

Hi there,
got the same problem if i use my two Nvidia GTX260.
My system:
Asus P6T
I7 920 @ 3,8GHz
2GB ram
Gigabyte GTX260 OC Edition
Nvidia GTX260
X-Fi XtremeGamer
-System (Win7x64) takes ~0min to start.
-Stuttering mouse, keyboard everything >.<
Deactivating the onboard sound doesnt help.
Newest Nvidia and Creative driver too =(
The system runs fine without the X-FI and two GTX260 no errors ect...
One GTX260 runs also fine with the X-FI
But two graphic cards and the X-FI..... **bleep** =/
I use debian as my main OS and it run still fine with both graphic cards and the x-fi...
so i think its just a driver problem.
Hope it will be fixed soon =/
If someone have any sugestions...please help us.
Greetings from Germany also =D
