X1 Carbon (3rd Gen, 2015) sound in xubuntu 15.04

I am running xubuntu 15.04 on an X1 carbon 3rd gen. Mostly works great. But sound volume is much lower than in Windows, whether through built-in speakers or through headphones. I have turned up all output devices and playback applications to 100% in the pulseaudo control panel, but it's still too quiet. If I go > 100%, it distorts. Has anyone else experienced this? 

AFAICT, it's a bit of a known issue with ALSA.
You might want to try fiddling with the preamp in the equalizer, and set any frequencies that the speakers can't play to zero.
FWIW, here's my foobar2000 equalizer for my W520 under Windows (no Dolby), which is a bit louder than uneqed and doesn't seem to clip audibly on most audio sources.

  • X1 Carbon (3rd Gen, 2015) questions

    Hi all
    Displayport
    The X1 Carbon 3rd generation (X1 3rd Gen) sports a mini 1.2 displayport (1.2 mDP). The 1.2 DP standard supports daisy chaining of monitors using multi stream transport (MST).
    Does this mean the X1 3rd Gen is good to power two 1.2 displayport capable monitors using just the 1.2 mDP?
    What about the internal / built-in display, can it be driven at the same time as two external monitors?
    If it is not possible with the mDP alone, is it possible to have all three (internal + 2x external) monitors driven by using the HDMI port also?
    Memory
    Is the 8GB memory limit due the lack of  >8GB modules - i.e. there is no 16Gb modules for thsi kind of use?
    Changing keyboard
    Is the keyboard a Customer Replaceable Part (CRU)? It seems to be so for the 1st generation, but I couldn't find anything for the 3rd generation.
    Thanks!

    Yes, but you'll need either a monitor with both DisplayPort input and output (you have to attach that monitor to your ThinkPad and the second monitor to the DisplayPort output of the first one) or a DisplayPort Multi Stream Transport hub.

    Both should be possible.

    No, it isn't (according to the Hardware Maintenance Manual).

  • X1 Carbon (3rd Gen, 2015) HDMI audio issue

    Hi,
    i recently used my X1 to connect it to my TV via HDMI. It worked like a charm. Yesterday it stopped working (Nothing was changed. Audio was working, lid was shut. Lid was opened the other day, audio is not working...). I get a video signal, but no audio. To verify, that this is no issue on the hardware defect issue, I booted to an installed Debian and there I get an audio signal over HDMI.
    After that I deinstalled the audio and graphic driver, rebooted, installed the audio driver, rebooted again, installed the graphics driver, rebooted again. Still no working audio over HDMI.
    After that I tried the procedure above again but installed the audio driver first. Still no success.
    The HDMI audo device does not show up in the playback device tab. Not even if I select to show me disconnected devices.
    OS: Win 8.1 64bit, drivers a all newest.
    What to try next? Any ideas?

    You are welcome...you need not worry about the temperature...the temperature (or the boot etc.) was on the older SM 941 one problem..and also you will not have any problem with the latest  bios version on the carbon  .there is no white list in the carbon bios  etc.for the ssd's (that means you can use any ssd's on the carbon..Samsung ,Toschiba ,Intel etc..at the moment only Samsung is x4 speed and the fastest on the market) in the bios..and  the bios will detect it as a bootable drive whitout any problem...and that's the truth and fact.Best regards..

  • 2560 x 1440 in VMware Workstatio​n 11 with X1 Carbon 3rd gen?

    I've installed Windows 10 Preview in a virtual machine with VMware Workstation 11 on my X1 Carbon 3rd gen. (20BS). By default, the display in the VM is recognized as Generic Non-PnP Monitor and the highest compatible resolution I can select for it is 1920x1440, which means I have black vertical bars on both sides. Other, higher listed resolutions are: 2048x1536, 2560x1600 and 2560x1920, but what I want is 2560x1440.
    As suggested in this VMware KB article, I have added the following lines to the .vmx file:
    svga.autodetect = "FALSE"
    svga.vramSize = 14745600
    svga.maxWidth = 2560
    svga.maxHeight = 1440
    14745600 is 2560x1440x4.
    However, this doesn't work. When I start the VM, I get a dialog box telling me: "The virtual machine could not be changed to the selected monitor layout."
    Is anyone able to run a Windows VM at 2560x1440 on an X1 Carbon with VMWare Workstation 11?
    Solved!
    Go to Solution.

    I found the solution here: disable 3D acceleration.
    This is done by changing the following line in the .vmx:
    mks.enable3d = "TRUE"
    to:
    mks.enable3d = "FALSE"
    I'm now able to run Windows 10 Preview at the full 2560x1440 resolution supported by my X1 Carbon, great!

  • X1 Carbon 3rd.gen Chrome crashes on Youtube videos after Intel HD Graphics Driver 10.18.14.42 update

    Hi!
    Chrome crashes at Youtube videos after Intel HD Graphics Driver 10.18.14.4206 update on Lenovo X1 Carbon 3rd.gen. Since the driver update yesterday, laptop starts suddenly to overheat enormously and become super-noisy as soon as I try to open a Youtube video , no matter on Youtube page, or a external provider with embded youtube video. Chrome becomes unresponsible and has to be terminated. Laptop continues to use fan at extreme level for abot 20 more seconds and then cools down. IE plays youtube videos without problem and all the other videos from Facebook i.e. are playing. Tried original and also Beta version of Chrome, which doesn't help.
    Kind regards,Daniil

    Hey guys, T450s user here. I think I found an even better workaround for this issue without having to disable hardware acceleration and lower the performance of Chrome as a whole. After long trial and error I found the that driver-related issue is generally narrowed-down to HTML5 acceleration for video playback. By installing the following Chrome Extension I was able to revert YouTube back to the old Flash-based YouTube player and now even 4K playback is absolutely stellar on my T450s running the latest .4222 driver directly from Intel's site! https://downloadcenter.intel.com/download/24964/Intel-Iris-Iris-Pro-and-HD-Graphics-Driver-for-Windows-7-8-8-1-64-bit This is of course by no means a fix of any kind but I think it is the best workaround that we have to this date without having to sacrifice performance in Chrome as a whole. Try it out guys! https://chrome.google.com/webstore/detail/disable-youtube-html5-pla/enmofgaijnbjpblfljopnpdogpldapoc?utm_source=chrome-app-launcher-info-dialog

  • X1 carbon 3rd gen, lcd panel upgrade

    Hello,I have a X1c 3rd gen with the FHD TN-panel. I don't like this panel very much, and would like to upgrade it. What options do I have, and where do I find the parts?If at all possible I would like to get the WQHD with touch panel. Can I install that on my X1c?Second option would be to get the non-touch WQHD IPS screen.  Thanks,Jonte

    There are no panels manufacturer p/ns or Lenovo service p/ns (FRU) on the site. So, if that site clames panels compatibility with x1c gen3, the IPS screen looks like a proper choice, its price matches the such screens.
    My only question is a screen surface type. X1C FHD non-touch screens laptop supports are anti-glare (have a look at the fru_bom file above), while the site promises glossy surface for the IPS screen. At the same time the IPS screen at the bottom (out of the stock) is matte. So, obviously it's needed to request the panels manufacturer p/n and Lenovo FRU the site offers..

  • X1 Carbon 3rd Gen & Windows 10 Issues

    apologies wrong forum

    Hi Mohassan903 and welcome to the community,
    I have an X1C 3rd generation and how I did it was I used my recovery drive and reset the machine to factory.  The Win 10 upgrade showed up right away, (Windows 8.1 wasn't installed yet) and I let it do the upgrade.  
    I'm not seeing any of the issues that you are seeing.  Windows 10 is lightning fast and so far, I don't have any issues with it.  My battery life during a download shows to be almost 8 hours.
    Did you do the bios update that has support for Windows 10?
    I just now put Windows 10 on and I'll continue to test it, but right now I don't see any issues with it.
    Regards,
    Dave

  • 3rd gen stops play, erases self, wont reload music?

    mid song yesterday my ipod stopped playing, i clicked a few buttons, which accomplished nothing (wouldnt play/pause/skip/turn off, etc), i let it sit for a minute or two, still nothing, so i "restarted" it (g3 = menu/play pause combo). it restarted... and asked me what language i wanted to work with, and then showed an empty ipod (no playlists, no songs, no nothing). bummer.
    i brought it home tonight to reset it and reload all the music, about 2 hours ago i started loading the relatively small library i have on this computer (~2800 songs, 12g). it's not even 1/3 of the way through. it's sporadically stalling on songs and sticking on them for a long time (it's been loading the current 5mb song for about 35 minutes now).
    i didn't notice anyone else with the same issue(s), but would love to hear if anyone else is having similar glitches. otherwise, it's a somewhat ineffective paperweight.
    thanks so much!

    It sounds like your ipod has restored itself, which is very odd.
    I myself have been having the same problem with itunes, have you got the latest version of itunes? If so, a lot of people have had trouble with it and I am currently attempting roll back to an older version.
    Also don't use the most recent ipod updater (1-10-2006) if you haven't already because I haven't seen anyone on here that hasn't had problems with it, including myself. It buggered up my ipod altogether and now I've got to roll back and restore my ipod using an older version of that too.

  • My iphone 4s wont connect in apple tv 3rd gen dont show the airplay icon, but apple tv can connect in Bose sound touch 20 via airplay, and the iphone also connect to sound touch 20 via airplay, so it means theres something wrong in my iphone.

    Hi jaredfox06,
    If I understand the issue correctly, you have recently purchased a used iPhone and you do not see your Apple TV in the control center in order to AirPlay.  To troubleshoot this issue please follow the steps outlined below.
    Try these steps first
    Make sure that you have the latest software on your iOS device and Apple TV.
    Make sure that both devices have Wi-Fi turned on.
    On your iOS device, go to Settings > Wi-Fi.
    On your Apple TV, go to Settings > General > Network.
    If you're trying to use peer-to-peer AirPlay, make sure that both devices have Bluetooth turned on.
    On your iOS device, go to Settings > Bluetooth.
    On your Apple TV, go to Settings > General > Bluetooth.
         If you don't see AirPlay in Control Center
    When an AirPlay-enabled device is available, you'll see AirPlay in Control Center on your iOS device.
    If you don't, try these steps:
    Restart your iOS device and Apple TV.
    Connect both devices to the same Wi-Fi network.
    On your iOS device, go to Settings > Wi-Fi.
    On your Apple TV, go to Settings > General > Network. If your Apple TV is connected using Ethernet, make sure that it’s plugged in to the router you're using for Wi-Fi.
    On your Apple TV, make sure that AirPlay is turned on. Go to Settings > AirPlay.

    Have a good one,

  • When I play my Ipod shuffle 3rd gen there's a moment when I start hearing interference until it stops playing, when I turn it off and on again it starts playing from the first song all over again, and once it sounded like the music was slowing down.

    My Ipod shuffle 3rd gen starts playing songs with some kind of interference until it stops playing, when I turn it off and on again it starts playing from the first song all over again, and once it sounded like the music was slowing down.  First I thought it was the earphones, but I exchanged them for newer ones and so far its the same

    You may want to do a Restore on the shuffle in iTunes.  The Restore button is on the shuffle's Summary screen in iTunes.  This will erase the shuffle, re-install its software, and set it to default settings.  If it's a software or data corruption glitch, the Restore should fix it.  After the Restore, reload or resync your songs, and try it again.  As a test, you may want to initially select a small number of songs to put back on the shuffle.

  • No sound on 2nd/3rd Gen 8gb

    I have an iPod Touch, 2nd/3rd Gen with the 4.01 software on it. It does not seem to be making any sound, externally or with headphones. There is no sound from apps.
    Strangely, if you try to play music, when you hit play, about a second later it will stop and go back to the music menu. So there isn't just a problem with the sound not outputting, but the Touch seems to know something is wrong and won't play music? Does that make sense?

    If you lose sounds for keyboard clicks, games or other apps, email notifications and other notifications, system sounds may have been muted.
    System sounds can be muted and controlled two different ways. The screen lock rotation can be controlled in the same manner as well.
    Settings>General>Use Side Switch to: Mute System sounds. If this option is selected, the switch on the side of the iPad above the volume rocker will mute system sounds.
    If you choose Lock Screen Rotation, then the switch locks the screen. If the screen is locked, you will see a lock icon in the upper right corner next to the battery indicator gauge.
    If you have the side switch set to lock screen rotation then the system sound control is in the task bar. Double tap the home button and in the task bar at the bottom, swipe all the way to the right. The speaker icon is all the way to the left. Tap on it and system sounds will return.
    If you have the side switch set to mute system sounds, then the screen lock rotation can be accessed via the task bar in the same manner as described above.
    This support article from Apple explains how the side switch works.

  • 3rd Gen Touch No Sound

    I have a 3rd Gen Touch running OS 3.1.3 and have an issue with sound from the internal speaker. I only get sound from the internal speaker if I select an alarm sound from the clock, I am also able to control the volume with the hard buttons. I do not get any audio through the internal speaker from any other source, video, music, applications. With headphones all audio works from all sources.

    I have also gone through reset and restore. I have tried both restore from back up and just a reset to factory settings. For instance, videos from youtube will not play sound through internal speaker but will through headphone jack.
