+5W power consumption when playing audio on X201 with Linux

Hi folks!
My Thinkpad X201’s power consumption raises from ~10W to ~15W when playing any kind of audio under linux. This problem does not seem to be CPU-related (for example when streaming with pulseaudio over ethernet instead of playing directly on the X201 the power consumption does hardly increase) and does not occur under Windows. I’m using Fedora x86_64 16 with Kernel v3.2.1 but it also occured with a v3.2.1 vanilla kernel; Fedora 14 and 15; Ubuntu 11.10 and 12.04 and so on.
I’ve allready posted my problem several months ago here: http://forum.thinkpads.com/viewtopic.php?f=9&t=99246 but haven’t gotten any useful answers.
I measured power consumption with powertop but also confirmed with readings from /sys:
while true; do bc -l <<< "$(cat /sys/class/power_supply/BAT0/current_now)/10^6*$(cat /sys/class/power_supply/BAT0/voltage_now)/10^6"; sleep 1; done

Is anyone able to confirm this problem or does anyone have a solution? I’m really desperate since I often use my Thinkpad as a big but wonderful portable music player (with headphones of course! Don’t want to annoy my fellow trainpassengers …).
Thanks in advance

BH-121 headset - hiss when playing audio

Hi,
I've just bought a BH-121 which I use with my Lumia 920. Generally it's great, but I'm really disappointed by a constant hissing noise when playing audio.
The hiss is very quiet, but noticable. It is not present when the headset is in standby, and I can hear it begin when the phone begins to transmit audio and end a second or so after the end of the audio. The volume is very quiet, but constant and doesn't vary according to the distance between the devices, how they are positioned, where I am, etc.
Is the headset supposed to make this hissing noise? Should I be returning it?
Thanks,
Matthew

Hi Matthew_,
Welcome to Nokia Support Discussions!
Upon checking, the said Bluetooth headset is not compatible with your Nokia Lumia 920. This is the reason why you hear some hissing noise while using the accessory. For more information, you can take a look at this link for the recommended devices:

Flash player freeze a lot when playing Youtube videos fullscreen from Linux, but plays ok from Windows (CPU: AMD APU)

Flash player freeze a lot when playing Youtube videos fullscreen from Linux, but plays videos ok from Windows (CPU: AMD APU).
When playing video in default size it's OK (windows and Linux), but when setting video in full screen, on Linux there's troubles: video is hashed (freeze every 3 seconds).
CPU : AMD APU Athlon 5350.
OS : Linux Mint 17 (64 bits).
Browser: Firefox v31 (on Linux and Windows 7).
Linux AMD video driver : Catalyst v14.4 (amd-catalyst-14-4-rev2-linux-x86-x86-64-may6.zip)

Hi s, well congrats on getting your brother's computer up and running. On your system, you have all correct Flash Player
files for IE and FF, as well as the SWO and SWF.
Since the Install of Flash Player, have you installed any programs that would have added any ActiveX Controls, or any other add ons or plug-ins?
Have you had an opportunity to see if your brother's computer has the issue you have when watching the same websites?
Are you using any ad-block in FF(Firefox) or any pop up blocker software installed? I can't imagine updating to FP version 10 alone would cause this.
Is this happening only on the BBC website? Does what you watch come thru the BBC website or youtube directly?
We have your brother's computer to use to determine what is going on. If he is able to see the BBC website and what you
are having problems with, then we can rule out the website.
Other browser add ons, anti-virus programs, etc. affect the browser. Even tho, no problem with vs 9. Sometimes updates
can have an affect, even with Windows as we all know:-)
Thanks,

Power consumption when PowerOFF: 24" iMac 2009

I really wonder about my iMac 2009 Modell: when using sleep mode I got 11-12 watts power consumption. But when shutting down the iMac (Power Off in Apple Menu), the same iMac takes 10 watts
Is this normal and how can I get sleep mode with far less or none watts?

I'm having the same thing with my 2008 24 inch iMac. I'm not sure if it is the hard drive or one of the fans, but there is a loud WHOOSH every time it starts up or wakes from sleep and the whirring noise is pretty much constant. It used to be completely silent, so this new sound is very noticeable.
Lately, the noise with abruptly stop and then make a struggling sound as if whatever is causing it is either going away or making it stop revolving or whatever (it would help if I could determine exactly WHAT is making the noise). I check iStat, but can't see any wide variance in the fans rpm speeds when it is happening or the heat of various components spiking. It is not affecting my computer use as it did the first time I had a similar problem (which turned out to the the hard drive, since replaced under warranty).
I bought Apple Care for this computer, so it is still covered under that, but I don't know if the fact that the noise is completely annoying to listen to all day is enough reason to bring it in for service and be covered under the extended warranty.

Photoshop crashes when playing audio

I am using Photoshop CS6 on Surface Pro 128GB to edit Video.
It crashes every time I like the preview the video and hit play in the timeline. First I was thinking it is the Video driver. Then I discovered, that it ONLY crashes when I hit the play button and it needs to play sound. As long as I mute all the clips it plays fine. I also have no problems editing. It is really only coaching immediately when it previews a clip with audio.
What can that be?
Please help! TNX!

Can't select apple tv in itunes when playing audio

I have the airplay icon. I select the icon and I have 2 options. My computer and Apple TV. If I select Apple TV nothing happens. It remains on My computer. If I start playing audio through itunes then try and select Apple TV nothing changes again. The audio stays coming out of laptop speakers. If I play a video, then select Apple TV, this works.
I had audio working the other day, but can't think of anything I might have done to change anything. But if video works, why doesn't audio?

Welcome to the Apple Community.
Do you have the power cable in, it won't show up with the power cable in.
Additionally, there have been some issues with the update servers, it's possible you won't be able to complete the update procedure anyway.

Power consumption when running window XP

Hi guys!
Hmm, recently i've asked a question on the other forums regarding the power consumption of my macbook pro while running window XP.
I realised that when i run window Xp, the battery life can only last around 2 hours, while when I run mac OS X, the battery life is around 4 hours.
However, I've got a reply at the forum and the reply cause me to be worried...
Here's the reply...
Power management is built into Mac OS X. So OS X constantly monitors the power consumption and energy profiles of the system while in use.
Windows XP and Vista, on the other hand, is built off the NT kernel which was NEVER meant for mobile computing. Unlike OS X, Windows XP and Vista does not have built in powe rmanagement: it actually relies on the low level BIOS (which is almost 3 decades old as of today) to manage its power consumption and settings.
Since the Macs do not boot using BIOS but rather, with EFI, to boot Windows, the EFI creates a BIOS emulation layer to support Windows. because this layer is emulated and the user has no control over it, Windows loses ALL forms of power management: the fans on the Mac will run at max, EIST will be disabled, wireless receptivity and hard disks will be set to consume all the energy they can grab, among many other things. Especially for hardware with moving parts like the fan and the hard disk: prepapre for premature hardware failure if left running at max performance all the time.
So can I ask, is this true?
Will running window XP on macbook pro causes the hardware to be spoilt more easily?
I have another friend who runs window XP on macbook and he told me that the hardware will not be affected by it, so can I reassure myself on that?
Thanks a lot. ^^

Yes, Win XP is a battery hog. I have an issue with Win XP not dimming the display the way OS X does before going to sleep. Running Win XP should not harm your hardware, it just drains the battery faster. I am looking into ways of improving batter life with Win XP. For now just make sure that you have the power settings in Win XP set to laptop/portable. If you need instructions on adjusting those settings I can provide them.

Flash Player 10 is not playing audio from Youtube with Vista and IE

Since installing FP10, I cannot get audio when playing YouTube video. I'm running Vista with SP2 and IE on an HP laptop. Flash 0 on my XP desktop plays audio fine, so I'm guessing its a setting on my laptop which needs changing back to what it was before the upgrade to FP10...any ideas please? I have uninstalled and the reinstalled FP10 as per other posts on this forum, but no success.

I too am experiencing this
[edit]
My problem was that I was not getting flash audio at all, including local publishes out of the IDE. The problem was that my Windows Audio service had stopped (for some reason).
To check :
(classic view) :: Start > Settings > Control Panel > Administrative Tools > Services >
(non-classic) :: Computer (right click) > Manage > Services and Applications > services >
(one of the above, then) :: [scroll down to 'Windows Audio'] > r-click 'properties', general tab, set the start-up type to manual (in the dropdown), and click the start button on the next line.

No sound when playing Audio-Cd's and burned movies

I recently bought a MSI DR-8A and it is working just fine, except when I want to play a burned DVD-movie or an Audio CD I don't have any sound
When I insert a original DVD, no problem whatsoever. What can this be??????

Hi Cave,
LOL. No, when i asked about the power supply, i was asking about the brand, the power rating (250W, 400W...) and especially the different amps ratings on the different rails
ex: 3.3V: 20A, 5V 18A, 12V 25A.
all those data should be on the power supply label (inside the case, though).
Power deficeincies can lead to really strange problems (but i dont think it is the cause here).
As for your problem, i'm kinda stumped. I asked about all i can think about and i still cant see a solution (more like i cant locate the problem)
summary:
DVD:
- disc is correct as it reads in another player.
- sound is correct, as pressed DVDs play correctly
- I'm not familiar with what you mean by Audio TS format.
CDs:
- play in the CDRW burner (so, good media)
- digital audio enabled on DVDRW drive
- correct sound properties (no mute or low volume)
- tried different softwares? (winamp, WMP6/7/8/9, DVD player...)
Does anyone see a problem/solution?

Dell laptop headphone jack does not work when playing audio and video in Firefox 27

My problem is similar to the one posted in this thread: https://support.mozilla.org/en-US/questions/986978?esab=a&s=laptop+headphones+don%27t+work+with+firefox&r=2&fpa=1&as=s
I believe it has little to nothing to do with extensions.
I have just installed Firefox 27 on the Dell Inspiron 3520 laptop of a friend. She is an unsophisticated user who has a computer for email, simple web browsing, and watching YouTube and other online videos. Because she frequently seems to end up with junk on her machine, I wanted to switch her over to Firefox so I could install ad and script blockers that would hopefully slow down the frequency of adware and malware roosting in her system.
The laptop is a Dell Inspiron 3520 with an Intel celeron CPU (64-bit), running Windows 8. There are standard end-user applications installed (Adobe Reader, VLC Media Player, etc.), but no tweaking utilities, etc. The audio drivers are Cirrus Logic High Definition Audio.
I've been troubleshooting the laptop today trying to track down why the integrated speakers continue to work when the headphones are plugged in, with no sound coming through the headphones. Because I had run a series of virus / malware / adware scans just before installing Firefox, I thought I had mistakenly deleted some system audio files.
It finally became clear after toggling multiple settings, playing with Windows and Dell sound settings, and experimenting, that the headphone audio jack still works as it should in the system itself (for example, playing videos through VLC Media Player) and in Internet Explorer. It is only in Firefox that plugging in the headphones does not send audio through the headphones nor cut out the integrated speakers.
Sometimes there is a silencing of the integrated speakers for a few seconds, but then the audio kicks in again. (I am using YouTube and a certain movie streaming website to test the audio).
However, if the headphones are plugged in before starting the videos, the sound comes through the headphones, but unplugging the headphones, then reinserting them, stimulates problem again. Not only that, but then in YouTube the video will stall and can't be restarted until the page is reloaded.
Again, this is a fresh Firefox install of less than 24 hours, with only Adblock, Adblock Plus Pop-up Addition, Flashblock, and NoScript installed. There are no themes installed and most of the Options are the defaults that are set upon installation.
I have both disabled the add-ons and uninstalled them entirely before testing the headphone funtionality. In both instances the problem persisted. I've also uninstalled and let Windows re-install the Cirrus audio drivers.
Does anyone else have any insight into this problem, and any potential solutions other than "start in Safe Mode" and "reset Firefox"?

Firefox can switch audio devices within ~ a + or - 10 minute period or so (Just a guess). At which point it latches onto the audio device and will never change until the entire process is shutdown (read last paragraph, there is an exception)
Ive had this problem for a few months now, at least. And I switch back and forth from my sound system and my wireless USB headset.
If anything will fix this i believe it would be disabling "Allow applications to take exclusive control of this device" in the properties of your default audio device, but i doubt it. I think this is an issue regarding the code in firefox itself.
I'd like to see this turned into a default feature, being able to disable and enable the ability to stay on whichever device was the default at the time of launch, or to always play on the current default device, even if its changed. That or being able to choose a specific device/devices (WOULD LOVE TO THIS).
Other than that I dont really have a solution, and I kind of doubt anyone will unless its addressed in the next update.
Oh I thought of one solution that doesnt require restarting firefox, disable the current audio device and the sound will automatically switch to the next available device. Or possibly when a new device is introduced?? I havent done much testing on the matter though. This is just my best guess based on my personal experience with firefox.

A/V stream out of sync with when playing audio on SourceDataLine

Hi,
I'm receiving a video and an audio stream via RTP and try to play them synchronized (audio synchron with lip movement).
I'm using a DataSourceReader in order to read from a datasource and play on a JavaSound SourceDataLine. This works pretty good but unfortunately the audio is played with a delay of approx 1 second.
else if (evt instanceof NewReceiveStreamEvent) {
     try {
          stream = ((NewReceiveStreamEvent)evt).getReceiveStream();
          DataSource ds = stream.getDataSource();
          Format format = null;
          // Find out the formats.
          RTPControl ctl = (RTPControl)ds.getControl("javax.media.rtp.RTPControl");
          if (ctl != null) {
               format = ctl.getFormat();
               log.info("Received new RTP stream: " + format);
          else
               log.info("Received new RTP stream");
          if (format != null && format instanceof VideoFormat) {
               Player video = javax.media.Manager.createRealizedPlayer(ds);
               video.start();
               this.video_player = video;
          else if (format != null && format instanceof AudioFormat) {
               JavaSoundDataSourceReader dsr = new JavaSoundDataSourceReader();
               Player audio = dsr.open(ds);
               audio.start();
               this.audio_player = audio;
          }          I already tried to synchronize them with
videoPlayer.addController(audio_player);
audio_player.start();but this is throwing an Exception:
javax.media.IncompatibleTimeBaseException
     at com.sun.media.multiplexer.RawBufferMux.setTimeBase(RawBufferMux.java:377)
     at com.sun.media.BasicSinkModule.setTimeBase(BasicSinkModule.java:52)
     at com.sun.media.PlaybackEngine.setTimeBase(PlaybackEngine.java:1672)
     at com.sun.media.BasicPlayer.setTimeBase(BasicPlayer.java:272)
     at com.sun.media.BasicPlayer.addController(BasicPlayer.java:1043)
     at VideoPlayback.update(VideoPlayback.java:281)Line 281 of VidePlayback.java is the "videoPlayer.addController(audio_player);" line.
My guess is that it should rather use RawSyncBufferMux instead of RawBufferMux but I don't know how to change this. Maybe directly as a processor option?
Please help as I've no clue how to improve this.

it should also be synchronized with the video :-)The problem with getting it synchronized is that Javasound & your sound card have internal buffering, so there is some delay between writing to them and hearing the sound come out...
Normally, JMF handles this internally somehow by aligning things to a timebase, which can be syncronized, and allowing Processors to fill up their internal buffers ahead of time during the prefetching phase so that everything that needs to play together can have an instant start time. As it goes along, presumably adjustments are made as things get out of sync.
My best advise to you would be to implement your Javasound stuff inside of a Renderer class, instead of a DataSink class. DataSinks are designed to take in data and write it out as fast as they can... whereas Renderers are given data at "real-time" intervals and are designed to be played.
When implementing your Renderer class, JMF should handle the syncronization for you. IE, it'll give you data as it should be played by calling the Process function, so you'll just need to write the data to your TDL as it comes in. I believe that "Process" may be called before "Start" to allow you to prebuffer some information, but you'll need to test that as I've never actually tried it.
