OpenSUSE Hardware :: Changing Switching Audio Devices On The Fly
Feb 8, 2011
How can I change my audio output (and input) from one device to another?
(Using a Sound Blaster and USB Headphones)
Changing settings in Phonon is a hassle, and it still won't change the sound immediately for the apps... Is there a quick way to just disable one device and enable the other, without having to restart the apps that use them? (For instance, right now Skype and my browser are outputting to headphones and amarok to my speakers - one enabled device that receives everything, bang! output for everything to another device and the first device is having a nap)
I can't see any settings in KMix to facilitate such a change...
what I can do to change sound cards quickly and easily?
I recall doing this in seconds in Ubuntu via their mixer, so would it be similar if I ditched KDE in favor of Gnome??
My Audio stops playing when switching to console from Xorg. When I switch back it continues playing. Is it supposed to be like this? Any way I can make it play continuously? I've already checked the Howtos and this forum for this problem but havent found anything similar.
I am running a java-based music player on two machines, one running 11.2 and the other running 11.3. I wrote the code myself, so I have complete control over it. Both machines have Sun java development kit installed, and both have version 1.6.0. The tracks of a given album are each played by a separate thread. Each thread requests the use of the audio device and plays through it. Under 11.2, the device is then locked for the use of this thread, and once the playing is through the lock on the device is automatically removed and the next thread starts playing its music without difficulty. I have no control over this lock, though. It appears to happen at the OS level, independently of my code.
When the exact same code is running under 11.3 the first thread plays through as before, but then the next thread does not manage to get hold of the audio device. It appears to play but no music is heard. When it finishes and the third thread tries to start, I get a "line unavailable" exception. difference between 11.2 and 11.3 in the locking mechanism of audio devices by an application? Is there anything programmatic I can do to remove the lock myself?
Say I have 2 speakers connected to 2 different sound cards. Under Windows, is it possible to have some sort of virtual device that would forward an audio stream to both sound cards? If this can't be easily done under Windows, a solution for Linux is also fine. lternatively, if the 2 speakers are connected to different channels of a sound card, is there any vendor-independent way to duplicate audio to both channels?
I have an external USB drive that is NTFS. It mounts fine under my account and my wife's, but only if I fully shut-down the computer between switching. While switching users or logging out then in with a different account it will not mount the drive. I am not sure what to do... but we both access data from the same drive.
I'd like to change the keyboard shortcuts for switching between workspaces. I have compiz enabled. In Ubuntu I see entries for these keyboard shortcuts in the Keyboard Shortcuts preferences app. They are not there on my Fedora 14 system. How can I add them?
The times aren't staying the same when switching between Slackware and Debian. When the time is right in one, it's wrong in the other.I've spent some time reading about this sort of thing, but this particular problem...
When switching off an HP dv-2140us with a fresh/clean Ubuntu Lucid install, an audio pop noise can be heard, similar to a DC transient on a loudspeaker.This has happened before on an old computer of mine (as reported here), but newer Ubuntu releases (including Lucid) have fixed the issue.
When I attach my ipod it gets automatically recognised and mounted to "/media/user's ipod". This is great but I would like to change the mount point to just "/media/ipod/" as it easier to use with gnupod (command driven ipod access oh yes!!) I've had a look around and I know how to mount devices but I'm at a lose as to how things in fedora are automatically mounted... I use gnome so from what I've read hal, dbus, and udev yeah? but I'm not sure what configuration files need to be changed. At the moment I'm just wanting to change the ipods mount point but I would like know more so any technical how-to or articles, or things to look at (I'm thinking X), to understand auto mounting would be nice too.
On a fresh install of squeeze (with the exception of some installed video firmware and the latest updates from the repos) from the kde cd.
System is running an ASUS Sk8V motherboard with onboard sound, also a SB Audigy 2 ZS sound card. Speakers are plugged into the sound card.
Sound worked fine before in Lenny except I had to create /etc/modprobe.d/sound with the following to get the system to prioritize the SB card over the onboard audio
My band play with a backing track running out of my laptop. We have a stereo mix of the backing track running into the PA system, plus another stereo mix of the backing track with a metronome running into headphones worn by our drummer. This means that the laptop is outputting 4 audio channels simultaneously. The catch is, i only have a two channel USB audio device, in addition to the two channel built-in soundcard. The trick i found to accomplishing what i desire within Windows was relatively simple - i used the ASIO4ALL driver, which effectively allowed me to combine the outputs into one "virtual" ASIO audio device which has 4 output channels, which i could then send audio to using my digital audio workstation software (REAPER). Luckily this has worked perfectly every time we've done it on stage, however at rehearsals it has on occasion failed as Windows has encountered errors, etc. Naturally it would be devastating for this to happen on stage, and so i've decided to try Linux out, as it has the reputation of being extremely stable (i've heard stories about machines being switched on for years without crashing).
Now, i've tried for a couple of days to get this to work, messing around with JACK, ALSA, and PortAudio, and using a range of programs such as Qtractor, Ardour, and MusE; however, i've only ever been able to get stereo audio to come out of one device at a time. I do however know that it is possible to do what i want, because i found a little DJ application which allowed me to set a different audio device to be in "headphones", whilst my other audio device outputs the currently playing track.
I'm by no means a proficient Linux user, however if something has to be done through a Terminal, with adequate instructions i'm sure i could do it. What i'm after though really, is a simple and clear guide to accomplishing what i want, which to recap is:
A to simultaneously output audio to two separate audio devices at once from within the same program.
I've an older PC, and I would like to use it with Lubuntu, because it's much faster than Ubuntu or Win XP (excuse me for the comparison). The only thing that prevents me from using Lubuntu is that I can't find any application to switch the sound card! How can I switch audio devices from Lubuntu?
I want to output two applications one to a headphone and another to the regular speakers, what app can I use?? it would be better if I don't have to move from audio player, I tried with alsa sound mixer but for some readon it doesn't list the speakers
I've just been setting up my new Revo with Ubuntu for use as a HTPC with XBMC etc.. Previously I had audio coming out through HDMI, but now I have lost all devices under the sound settings.
I was using alsa mixer, is there any way of getting this working again? A HTPC without sound is a bit useless!
I can't really say what I've done, as I took a few approaches to it, but I've tried to remove everything so it's back to normal. I think maybe it happened after updating some NVIDIA drivers..
I am using Ubuntu 10.04 LTS - the Lucid Lynx. I am using the laptop to play video files and view it on TV using HDMI output. No problems. Requirement: to play simultaneously a different media file and be able to listen through say headphone / laptop speakers. While a movie audio is only heard on TV, other audio is heard only on laptop speaker.
For some reason on any application that uses sound, but doesn't allow me to specify the input/output audio devices I don't get anything. I want all audio to go to my USB Headset, and not the onboard soundcard. To start off with, here's alsamixer: Here's a screenshot from Mumble (voice chat) that shows that I've set the USB headset device in there, and it works 100% fine on Mumble.

As you can see from the alsa-base.conf above I've tried specifying snd_usb_audio as the default device, but it's not working.
I always keep my headphones as well as my 2.1 speakers connected simultaneously on my PC (Gigabyte motherboard). Both these audio devices work fine simultaneously on my Windows 7, but in Ubuntu, only my headphones work, speakers don't work at all. I tried changing some settings in SOUND PREFERENCES as well as ALSA SOUND MIXER, but not luck so far.
I would like to use HDMI on my graphic card for audio output. ALSA shows it as a card with 4 devices and I can get sound through one of them (the other three are different channels, perhaps? I have only stereo output connected). Although Pulseaudio has the right card set as default, it seems to me that it plays on a wrong device. Pacmd shows that the sink has parameter alsa.device set to the first device listed by ALSA, but I can get sound only from the second one.How can I force Pulseaudio to use another device of the same card as a default output?
I can get sound out of my machine just fine, but for some reason, no matter what audio player I use, every time I change the song or pause playing half my speakers will kill sound and it will seem like the sound profile has reverted to Analog Surround 5.0 Output. When I check my sound configuration it still lists 5.1, and I have to select another setting then change it back to 5.1 to get my speakers all functioning again.
script which adjusts my NVIDIA settings to HDMI and also my Audio output to my digital output. I feel its quite a lot of clicking to get my signal to my LCD.So I hope somebody already had this idea and can give me the script or can assist me in writing it myself. I think its not a complicated script. i guess its only 2 lines. But i am not exactly a pro in Ubuntu..So as i said i have a NVIDIA graphic cardand aplay -l shows
**** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: ALC1200 Analog [ALC1200 Analog] Subdevices: 1/1
I'm still working on ubuntu 9.10 with an acer aspire 1810tz. To use my microphone I found out that I have to change my microphone settings because it's mono and the default setting is thinking it's stereo: With the Volume Controller I setup one chancel to 5 and the other to 90 and the mic is working fine. Starting Skype and using it I see that the setting is reducing the volume for the mic below 20, so nobody can hear me. I tried closing first Volume Controller and then starting Skype, no matter the volume of the mic is reduced. How do I stop this behavior?
Preliminary checks of sound level settings and obvious dumb stuff but there is still no sound. The problem seems to be that the system does not recognize the existence of the sound card and insists on using alternative audio devices.
on a newly installed opensuse 11.4 x86_64 I am unable to find the settings to switch keyboard layout from english to german to french or any other language .it used to be in the system settings Keyboard-->Keyboard layouts -->> activate german btw french etc...
I have behringer UCA202 usb card, after plug to usb, it just works , I have only small problem with alsamixer, which still shows by default my integrated HDA Intel, I could switch it by F6 or by alsamixer -c 1no problem, but I expect that default card is now plugged "USB audio", so why alsamixer recognize default audio device as HDA intel and not a USB Audio ?anyone who has two or more sound cards with the same issue ?
I'm thinking of installing openSUSE-11.1 Gnome on a Fujitsu-Siemens Amilo 7400M laptop because the wireless in Gnome is much more user friendly than KDE3/KDE4 in openSUSE-11.1. The idea is to give this laptop to my 84-year old mother and things need to 'just work' for her (she currently has a desktop running openSUSE-11.1 KDE3 that uses a WIRED interface to the web).
I refuse to update this laptop to openSUSE-11.2 nor 11.3 (nor other recent distributions) because every kernel update after the 2.6.27 kernel has broken the Intel i855GM graphics drivers for that laptop. There are many bug reports and none have fixed the problem for this Fujitsu-Siemens implementation of the i855GM graphics.
Hence I am looking at Gnome.
I booted the laptop to a Gnome openSUSE-11.1 liveCD and wireless is easy and works great. But audio is very very VERY bad. It is incredibly user unfriendly and it does NOT work well. I assume that is because pulse audio in openSUSE-11.1 was very immature.
I note these updated packages in the openSUSE-11.1 update repository:
Code:
So my question is, did the updates to pulse audio (in the openSUSE-11.1 update repository) fix the pulse audio situation? Are there ANY helpful views on this?
Currently my wife is using this laptop with KDE-4.4.4 (and openSUSE-11.1) so I can't just install Gnome and play with it without taking the laptop away from her for a while (note the hard drive is too small for a dual boot of KDE/Gnome).
dell inspiron e1505 3.2 gb ram 1.86 ghz intel core duo ati x1400 gfx opensuse 11.4 kde 32 bit.
okay, here are the details: can't play any audio with amarok when desktop effects are enabled because the minute a window is moved, it will distort the audio. even when disabling desktop effects, some applications still cause this. can't play videos videos even with desktop effects disabled because of the same reason.
i just switched from ubuntu and when i ran version 11.04, i had to disable kms to do anything. i tried on opensuse 11.4 and the audio was flawless but the gfx went all to hell.
on my PC I have 2 sound drivers, one from the mainboard (AC97) and one PCI card (ES1969). Because the mainboard sound path did not recording, I installed the PCI sound card and with 11.1, I managed it to play and record all audio data. With 11.2 the PCI sound path plays the system sounds (suse start-up or shut-down sounds) but not the streaming audio data (skype, flash player). But these are played by the mainboard audio instead. The audio-tests from yast->hardware->sound work for both paths. How should I configure the system to redirect the audio streams to the desired (PCI) audio path? The PCI audio is set as primary sound card and is not muted.
I like to explore, but it seems this time I have gone too far. I tried using vi to edit /etc/sysconfig.d/windowmanager but no changes seems to do anything.
