Ubuntu Multimedia :: How To Control Master - PCM And LFE
Oct 18, 2010
Dell Inspiron 9400/E1705. In earlier versions of the sound settings in Ubuntu, I could press CTRL, then MASTER, PCM and LFE, and the volume buttons, whether on the front, using Fn + UP/DOWN or the slider in the systray would also lower or raise the volume of the subwoofer, because they would all be "bonded" together.
I have tried several things to make this work in later versions of Ubuntu, but nothing's worked. alsamixer won't allow it, sound settings are too simple, the ALSA-packages are so numerous it would take me months to check them all.
I know the solution is as simple as making the volume controls regulate all three, but I don't know how to do it anymore. And it's a real shame actually, because that's the only thing not working on this machine, and it was such an easy fix up until 9.10 (I think)
I've just removed PulseAudio and installed Envy24Control in order to make sound working with my M-Audio Delta 1010LT, it's working fine now, but the only problem is that the master volume control disappeared, and the buttons on my keyboard (volume + and volume -) are not working (with PulseAudio they were fine). Using Ubuntu 10.10
I'm running Kubuntu 10.10 32 bit on an old DFI KT600AL motherboard based system using the onboard VIA 3058 AC97 audio (because it supports front panel audio connections and none of the add-in PCI soundcards I have do). I have an old Gateway/STB TVPCI TV tuner card (mainly wanted the FM radio part to work) hooked up to the cd audio connector on the motherboard because the digital audio over the pci bus apparently isn't supported for this card (neither is the onboard analog mixer on the tv tuner card, I had to hack a CD-ROM audio cable and solder it to the audio outputs of the tv tuner module on the TV tuner card). When I use the master channel as the master channel (selected in Kmix) then as one would expect it affects the output volume of all other audio playing on the system except that which is being handled by the PCM channel. On Windows the PCM channel was also affected by the "Volume Control" slider such that ALL volume levels were reduced when moving the slider. I'm hoping someone can help me figure out how to make it work like this on Kubuntu.
First off I should warn you that I (like many users of older hardware that is not properly supported under PulseAudio) have uninstalled PulseAudio (because it's garbage) and am using Alsa to manage my audio hardware. I would think that there would be some way to do this using the 'amixer' application to add the PCM channel as a component of the 'Master' channel so that when the volume is turned down using the 'Master' channel control it will affect the PCM channel too (at least the output to the speaker jack, not necessarily the capture or mix volume though), but I'm not really any good at doing things from a terminal window and the options for the amixer command kind of confused me.
My volume control seems to have only three settings: TOO LOUD, VERY QUIET, OFF. If I adjust the Master volume slider from the Panel, only about the right 1/8th has any effect and if I slide it past about the 95% mark, I get no sound at all. At the far-right end of the volume control, I get total volume. It's basically like the slider only has any impact in the top 5% of it's space. Below 95% of the slide, there is zero volume.
It's so drastic, that one tap down of the volume button on my keyboard kills the sound (because it nudges the slider past that 95% mark). This happens in the Audio settings, etc., system-wide. If I adjust the volume for an individual app from within the app (MPlayer, for example) it behaves exactly as expected (that is, app volume works smoothly, it's just master volume that has this issue). I have run through most of the "obvious" things-- I'm wondering if I broke something by installing the extra KDE packages to get Amarok to work.
On my Fedora 14 system, the gnome-volume-control-applet manipulates the Front channel, rather than Master (or PCM), which means I continually have to use alsamixer in terminal to adjust the audio volume in the other channels.In earlier version of Gnome (pre-pulseaudio?), this could be configured in the volume control preferences, but no more.Anyone know how I can fix this?My audio adapter is pretty standard Intel stuff. lspci: ode:00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller
I'm managing a residential network. Each flat is its own subnet, and can only communicate with the other flats through a router (i.e. no broadcast). 95% of these 300 subnets only contains windows computers (from lambda users).
My final goal is to be able to browse the entire network from any computer.
I set up a samba server acting as a wins server, and every computer is aware of it because it is registered in the dhcp. So name resolution is working fine for everyone.
The same samba server is set to be the "Domain master browser":
workgroup = WORKGROUP wins support = yes prefered master = yes local master = yes domain master = yes os level = 65
When I browse the network (using "net view" or "browstat view"), I can only see the servers which are in the same subnet as the domain master browser.
Now, when in a subnet the computers arrange themselves to find a "local master browser", the only visible computers are the one in that subnet.
What I don't understand is why all the local masters don't synchronize their lists with the domain master.
So, to sum up, every subnet get the following behaviour:
-if a local master is elected, the only visible computers are the one in the same subnet.
-if no local master is elected, the only visible computers are the one in the subnet of the domain master.
-if I add another samba, configured as a local master winning all elections, then the magic is working and the lists are synchronized.
What is expected: -every computer can see all the computer from all the subnets.
Ever since upgrading to Karmic, I haven't been able to adjust master volume when my USB headphones are chosen as the output device. If I try to adjust my master volume (via the media keys on my keyboard or gnome-volume-control), the output volume doesn't change until it's entirely muted. I can adjust the master volume fine when I'm outputting through internal audio.I am able to adjust the volume fine on an application-specific basis, but this becomes quite a nuisance, especially when I switch between internal audio (where master volume is regulated) and USB audio (where master volume is always at full-blast). This worked fine in Jaunty, and stopped working once I updated to Karmic. My USB headphones are listed as "Storm HP-USB500 5.1 Headset".
I have a load balancer with 2 web servers behind it. The web servers rsync with cloud storage to update their apache directories 1 time every hour. Apache is just running php pages that pull/push data to a DB so they dont need to be updated that often. However I need to figure out how to implement a Master/Master MySQL setup to have my web servers point to for the PHP stuff. I need to implement it without having a single point of failure. The Load balancers are useless for failover as they only detect availability based on Ping request. So putting a master/master setup behind a Load Balancer is out. what is the best way to setup the master/master mysql in a HA setup without the use of a load balancer provided by the host?
i'm using opensuse 11.3 64bits and upgraded kde from 4.4.4 to 4.6.0 now i'm having some problems with audio. it seems kde have problems with audio-devices. sometime i message about none workin devices and ask me to remove it. i manage to get sound from amarok, but not from web-browser lika videos. the computer is a dell latitude d830 with intel hda-devices. computer is docked in a dell d-dock. i can't adjust master volume using computer buttons or kde-volume, so i have to use volume on external speakers.
I'm running squeeze (last updated today), and everything has been working great. There is only thing that would simplify my life minutely..Anybody know how can I have the volume buttons on my laptop change the "pcm" channel volume rather than "master"? If they could control pcm, then I could adjust the volume coming out of my headphones or my computer speaker (both controlled by pcm, but not master...seems strange to me) with just one click.I tried to find this info online, but all results seem to refer to an older version. The simple "click here, set this" solution no longer is possible.
I find xcompmgr more than adequate for making a desktop look pretty modern, and I don't like the more extravagentCompiz gimmicks - but there is one thing that irritates when using xcompmgr which someone here might have worked round.
Rounded window borders don't draw and redraw properly when using the Terminal (gnome-terminal and the LXDE and Xfce ones) or system monitor and moving them from their default place. You get this little white botch at the corners. I'm not massively technical and I'm ambivalent about how much more I want to learn as I have plenty of creative outlets already, but I would like to solve this. Somehow xcompmgr is treating these programs as a different class? It's capable of drawing the window borders properly as it is just these two programs that get botched. Possibly this doesn't get noticed as maybe people usually use xcompmgr with openbox and LXDE and their square window borders. I did do a search but there was nothing matching what I saw.
I was looking around for a way to control rhythmbox playback on a remote computer with ssh (or telnet) and found a few archived posts asking about this without a working answer.After a little searching I found a way to do this on commandelineful.
Everything is plain and simple. I want to know what's the least painful way to control vlc from local command line while having GUI as well?
I would like to e.g. use something like "vlc --pause" in one of my bash scripts to pause music if something hapens. So rc interface is useless, is it not?
not making a thorough search on this as the irrelevance of results is beneath me... Well actually I have made it but it was a while ago and to no avail since the new vlc shipped with karmic got rid of the old http interface which allowed to do this just by using wget on an url....
While trying to get the iPlayer working (Ubuntu 10.10) I turned on parental control and set up all the passwords and other stuff it needed. Now when I try to play something with guidance it says wrong password and also wrong answer to security question. I know 100% I am putting the correct one in.
I'm running Natty with the official Blender 2.57 32-bit build.This same problem occurs with previous version of Blender and Ubuntu, although not with Blender 2.4x or any other programs.Pressing the control key does nothing in Blender. Pressing 'Ctrl+S' causes the active object to scale, as if I just pressed 'S'. If I run 'killall gnome-settings-daemon', it temporarily works normally, but then I lose Gtk themes and icons and stuff.
I'm on a Dell Latitude D620, and I haven't messed with any keyboard settings.I know people using the same hardware and OS that can use Blender fine, so I'm guessing there's some sort of xinput configuration or something that got messed up somehow.
I am the owner of a dj service we are trying to control intelligent lights using a uDMX interface from anyma, and Q Light Controller (qlc). As of now i have QLC Installed, And The uDMX Plugged in And It Doesnt Work, I Have installed so many things to try to get it working! Ive Installed libUSB DMX4Linux and many more... Nothing seems to work.
First some background: I currently have iTunes running on a Vista box attached to my TV. I have an Ubuntu box running 11.04 and shairport which serves as remote speakers for the iTunes server. This works fairly well as I can control it with my iPhone, or iPad etc. Very slick interface and my wife loves it .
But I would prefer to not use iTunes to as the server. I would like to let that Vista box sleep most of the day. Doing a little bit of reading it sounds like I should be able to use mt-daapd as a replacement for iTunes. So I installed firefly and gave it a shot. I can get it streaming music fine. But I cannot Apple's "Remote" app to add the new library. When I did some poking I read that I should make a file that ends in ".remote" and put my device name + the pairing passcode from my iPhone in this file.
When I enter the "Add Library" mode on my iPhone it should broadcast an mDNS event. And in fact it looks like it does because: avahi-browse -r -k _touch-remote._tcp Can see my iPhone. But when I do a tail -f on the mt-daapd logfile I never see a connection come up. I have tried debug level 8 in the messaging.Still nothing. In my search for a fix I noticed mt-daapd is no longer being developed but there is forked-daapd. This is actually where I found the instructions for pairing via Remote.
Should I bail on mt-daapd? Will there someday be Ubuntu support for forked-daapd?
Anyone here have a good solution for individually controlling sound output without relying on that individual programs audio settings? For example:I am writing a paper while listening to some nice creative commons jamendo music, and I have to look something up online - I don't want to hear random audio/video advertisements.
or I get a VoIP call and I want that program to continue with sound, but want to mute my 8bit sequencer and whatever else.
In sound control, the bar that shows your volume level has a mark about 75% across that signifies your max volume without digital amplification.[URL] If you drag the settings dongle to the right of that mark, your volume does get louder, but I cannot achieve that effect via my usual keyboard shortcuts (e.g. F8-for-volume-down, F9-for-volume-up). They stop increasing volume at that artificial 100% mark, they do not digitally amplify as I want them to. As a result, every time I want to amplify my volume, I am forced to go all the way into sound control, which (to me) is dumb. Is there a way to set the 100% mark at the ACTUAL far right of the control bar, instead of 75% across, so that my keyboard shortcuts blend right from analog-max to amplification?

Catalyst Control Center (CCC) is not saving the changes I make. I saw a couple of thread about this that had links to instructions on how to install CCC, but it still doesn't work for me.
I start CCC with 'sudo amdcccle' and the GUI appears. I can use it to make changes; however, it never saves them. After clicking OK, it instructs me to restart the system. After a reboot all the setting are back to the default.
I have installed CCC three different ways:
1) sudo aptitude install --without-recommends fglrx-amdcccle | tee fglrx-amdcccle.log
In all cases, the fglrx driver works, and 'sudo amdcccle' brings up the GUI, but the changes are gone after a reboot.
Hmm, at the moment, when I click "Apply" and the "Do you want to keep these settings?" 15 second countdown box appears, no changes occur even temporarily.
I've tried doing a fresh install of 9.04, then upgraded to 9.10 (I have problems with the 9.10 command line installer not installing grub) among other things.
I have one laptop connected to my tv. It has all the videos on it. ther laptop(actually a netbook) that I have set up to do light browsing on. Both are running ubuntu 9.10. I would to be able to remotely control vlc running on the laptop connected to the tv from the netbook. I have been searching for a while and have found hints that this is possible, but everything either refers to streaming from one machine to another or doesn't give enough examples to figure it out. I have tried enabling the http interface, but I can't access this from another computer.
I upgraded from 9.10 to 10.04 and my volume control disappeared from the panel. I have reinstalled pulseaudio but it had not re-appeared. I can't find it in the Add Panel list nor can I find it in the Pulseaudio volume control application as an option.
I've just upgraded to kUbuntu 10.04. I've been using Gnome for a few years now, and felt the need to try KDE again. I've managed to get my NVidia 8200 with HDMI audio working, but have one last annoying issue.
I can't control volume with my RF remote or keyboard.
More to the point, the keys control the sliders in kMix, but to no effect on the sound. This is likely because I need to use Pulseaudio to get my HDMI working. The sliders in Pulse volume control, control the volume nicely. Either I need a way to force kmix to talk to pulse, or a way to re-map these keys to control pulse.
I recently switched from Ubuntu to Lubuntu on my Acer Aspire netbook. When I had Ubuntu, in System Preferences I had a Sound mixer that would allow me to set the volume beyond 100%. It simply said "Sound" and was different than the applet feature. Both were preinstalled. With Lubuntu, I seem to have lost this option. I went through and installed Gnome ALSA Mixer along with Pulse Audio Control, but neither does what this simple volume control feature on Ubuntu did. My speakers are horrible, and the previous "Sound" feature really let me crank it up a bit. I'm not trying to blow my speakers out or anything;
how to set at least my headphone/lineout socket precisely to -15dB at boot up? If I knew how to make amixer commands permanent, I wouldn't be re-raising the issue
The Gnome GUI volume control is fine in normal circumstances but to set it accurately requires a bit too much fiddling, IMO - now if someone were to adjust the programming so a dB readout accompanies slider movement, rather than as a pop-up after adjusting the slider, 'twould be more ergonomic, IMO.
