My fix was to run it like this parec --format=s16le --channels=1 --latency-msec=5 | ./baudline -stdin This uses parec to read from pulseaudio and pipes it to baudline.

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 ...

In most systems if not all, ACPI can handle this event. To test that: Run acpi_listen Unplug & replug headphones, example output: (mic/ears share in same jack on my laptop) jack/headphone HEADPHONE unplug jack/microphone MICROPHONE unplug jack/headphone HEADPHONE plug jack/microphone MICROPHONE plug Put your-script.sh in /etc/acpi/ Add an event ...

Routing sound to different sinks with PulseAudio Yes this is possible, but you need more than one soundcard (PulseAudio calls these sinks) for this to work. Don't worry, if you have something like a headset that is connected via Bluetooth or USB, then this also counts as another soundcard. Using the PulseAudio GUI While you can configure PulseAudio from ...

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.

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.

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, ...

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 ...

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 ...

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 ...

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

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 ...

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 ...

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 ...

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 ...

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!!

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 ...

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 ...

I tried the Xonar U7 on Mint 16 (based on Ubuntu 13.10) and it works fine (I haven't tried multi-channel though). Absolutely no noise, the sound is perfect with alsa k3.11.0-12-generic, alsamixer v1.0.27.1 and pulseaudio 4.0. On 29th January the alsa-wiki page provided in the first post was updated, and now the Xonar U7 is supported. With the alsamixer is ...

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 ...

Not sure if this is your issue, but my Y410p with ubuntu 13.10 has this issue. I get a high pitch noise if I have my keyboard backlight on low brightness. If the keyboard backlight is off or on high no noise. I use the fn+space to toggle it.

Update Jul 3, 2014 As of Ubuntu 14.04, the ALSA driver is natively supported in the kernel, so the download-compile-install process for the driver should be skipped. The remaining of the instructions remains the same. Instructions In order to get this card to work, you need to set up ALSA (Advanced Linux Sound Architecture). Download the latest stable ...
