The problem can be from several factors which can be related to the Ubuntu system, hardware of the PC, cables used to connect to the sound (Headphone, Cable PC-to-TV, etc..) or the actual device that is connected to the PC (TV, Big Speakers, Home theater systems) Here are the steps to check who has the fault. Let us start with Ubuntu (From the Inside to the ...

My experience with the Xonar U3 and 11.10 on a Samsung RV511 laptop has been very good. Installation is dead simple, just plug in and go to Sound Preferences (right click on Sound icon) and the hardware, input and output tabs selecting in turn the USB Advanced Audio Device. And there you have it, a noticeably improved sound output, haven't used the Xonar ...

I posted the same question on Launchpad. Here was the answer I received from Mark Rijckenberg: Please run the following command in a Terminal session: gksudo gedit /etc/modprobe.d/alsa-base.conf Using the gedit editor, add this line in the /etc/modprobe.d/alsa-base.conf file: options snd-hda-intel model=dell-m6-dmic Save the change, ...

We can direct the output of a running application to another soundcard or sink with pavucontrol as depicted here: These settings are valid as long as the application is running, however they can not (yet) be made permanent.

Perseverance pays. I found this lovely patch posted at: https://help.ubuntu.com/community/DigitalAC-3Pulseaudio I now can set the device in System Settings>Sound to 5.1 Digital Audio, get discrete channels sent to my receiver via PCM and the resulting audio is at the correct speed/pitch. Tested playback with 5.1 wav files and a couple DVDs...so far so ...

snd-cs46xx is a Linux kernel module supporting Cirrus Logic's Sound Fusion CS46xx audio controllers. It is an ALSA driver included in the Linux kernel. At linux-2.6 2.6.23-1, the binary-only firmware in this driver was removed (see the package changelog), due to discovered firmware licensing issues. The driver was disabled at this time. Firmware was also ...

You can blacklist its kernel module. You can do that by editing blacklist.conf sudo vi /etc/modprobe.d/blacklist.conf You should probably add something like this: blacklist fglrx blacklist radeon alias radeon off alias lbm-radeon off That will blacklist ATIs proprietary driver (fglrx) as well as its opensource counterpart. Edit: Ok, how about using ...

To find out what your sound card supports, have a look at /proc/asound/card0/codec#2 (you can just type cat /proc/asound/card0/codec#2 in a terminal to read it) Now, the 0 and the #2 may vary for you, type cat /proc/asound into the terminal and hit tab to see what's there, in this file (which isn't really a file, but never mind), you'll find something ...

Actually, you CAN slide all the way up: when using the indicator applet icon, the max slider IS 100% unamplified To raise it ABOVE 100% (ie, to use amplified levels), you must go Sound Preferences. So, when using the applet icont, go ahead and dont worry, it wont be amplified. You can check this yourself: open the Sound Preferences window, and leave it ...

Normally you won't be able to play back midi by default. Install ubuntu-restricted-extras (should pull in everything), and then try again. You may also need to search for sound fonts in synaptic and install a package (you will need fluidsynth - but I think this gets pulled in by the package I mentioned earlier).

If you are lucky, you simply open 'alsamixer' in a console. Hardware 'channels' have volume bars; switches do not. Use the 'm' letter to change settings. Maybe you have a switch to change that input/output behaviour. Use F-keys and left/right arrows to see all your options. Now having pulseaudio as default in Ubuntu, all these alsa settings are somehow ...

https://launchpad.net/earcandy https://launchpad.net/~earcandy-devel/+archive/ppa Its not complete but it allows you to push sound to headset.. btw pulse audio will not be doing this by default, the developers do not agree that sound should move devices in this way. I should add to any one who knows a little python, help would be gratefully accepted to ...

Maybe hardware compatibility in linuxcompatible.org can help you http://www.linuxcompatible.org/compatdb/lists/hardware_linux.html Maybe this can help too http://www.linux-sound.org/drivers.html Here is another list http://tldp.org/HOWTO/Hardware-HOWTO/sound.html

I experienced the same problem and I have written a post about the solution I found here. Basically what I did was this: Open the file /etc/pulse/default.pa by typing the following in a terminal: gksudo gedit /etc/pulse/default.pa Change the line that says load-module module-udev-detect into load-module module-udev-detect ignore_dB=1 Save and close ...

If Ubuntu login sound and alert sound are not working then here's how to fix it: Download dconf-editor if you haven't already. Then click in this order org -> gnome -> desktop -> sound. Once in sound, click on theme-name. The default value is freedesktop. Change it to ubuntu (lowercase!) and exit. Log out and log back in to hear the glorious drums!!

The most probable cause of constant noise coming in from the speakers is usually mic boost. In order to disable this: Open a terminal. Type alsamixer and press Enter. Reduce the Mic Boost and Internal Mic Boost to zero. Refer to screenshot.

In order to get this card to work, you need to set up ALSA (Advanced Linux Sound Architecture). Download the latest stable releases of alsa-driver, alsa-lib, alsa-utils, and alsa-firmware from their wiki page here and extract them. 0. Pre-reqs To make sure you have all the pre-requisites for compiling code, run the following command: sudo apt-get install ...

Firts of all, you should check if you have /usr/bin directory in your $PATH in terminal with: echo $PATH If the $PATH is ok, check if alsamixer is there: ls -l /usr/bin | grep alsamixer If yes, try to run alsamixer like this: /usr/bin/alsamixer If still doesn't work delete .asoundrc file (in your home directory) and /etc/asound.conf (if you have ...

That "crack sound" you hear is when you plug off the connector is the contact in the plug socket, that bridges the gap between the left and the right audio signal (for a really short time). This ends in some kind of back coupling of the signal: the weird crack sound. So this cannot be avoided through software, because it's a hardware related idiosyncrasy of ...

I have used this device in Ubuntu 11.10 and my experience is that it does improve the sound quality and adds a lot more power to the output (Acer Extensa laptop). Of course the actual improvement depends on the quality of the onboard sound chip. Unfortunately the Xonar U3 Audio Center SW doesn't support Linux but the device is usable also without it.

I had the KVM card removed from the server and the onboard audio was automatically detected. This card obviously isn't very well supported by the manufacturer in Ubuntu, so for anyone coming across this, I would suggest you go with an external KVM solution that isn't tied to your specific server hardware.

When I looked through the list of loaded kernel modules on my system: lsmod | less I found this: snd_ens1370 21536 0 gameport 16776 1 snd_ens1370 snd_ak4531_codec 9856 1 snd_ens1370 snd_pcm 80388 5 snd_ens1370,snd_intel8x0,snd_ac97_codec There was no doubt in my mind - I needed to stop the kernel from loading the module ...

In theory, this should be handled by 'PulseAudio Volume Control'. There is a button to select a device as the default device, though imho poorly titled as 'Set as fallback'. More info about this feature here: http://ubuntuguide.org/wiki/Ubuntu_Oneiric_Hardware Unfortunately the feature doesn't work. As soon as a USB audio device is unplugged the setting as ...

The following is the correct way: Issue the arecord -L command. Look for the plughw values which corresponds to your hardware. Please note that plughw represents a hardware which has been plugged into the computer. Crosscheck the values in /dev/snd/by-id directory. When you unplug the webcam(s), the by-id sub directory will vanish from the /dev/snd ...

Things may sound "better" in Windows because of the Waves MaxxAudio 3 package, which is a software sound-enhancer that can "improve" bass, etc on relatively tiny laptop speakers. It uses psychoacoustics to do this, i.e. it manipulates the sound so that the human brain is tricked into making it sound "better". Note that the Waves drivers are Windows-only, so ...

You can install a synthesizer from the Software Centre such as Bristol as well as a program to route midi commands from the keyboard to the synth, such as Jack Control. Midi can either go over two different protocols, ALSA or Jack and Jack Control handles both. Bristol, by default, uses ALSA. Jack Control opens several windows and can look a bit forbidding ...

I found this little snip of code about two years ago; it enables line-in throughput: pactl load-module module-loopback latency_msec=1 This disables it: (It used to work on 10.04 but doesn't work in 12.04) pactl unload-module module-loopback

I added the following to /etc/rc.local echo 1 | tee /sys/module/snd_hda_intel/parameters/power_save echo Y | tee /sys/module/snd_hda_intel/parameters/power_save_controller pkill pulseaudio pulseaudio --start exit 0 And it seems to have done the trick...

That echo could come from your microphone in your headset. You need to mute the microphone sound. Open a terminal and run the alsamixer program. Use arrow left/right keys to move between sliders and press M for (un)muting a slider. Press Esc when done and run exit to close the terminal.
