Ubuntu Multimedia :: Pulseaudio: Removed USB Speakers Now No Sound
Apr 4, 2010
I took out some USB speakers that had been working for many months because I needed them on another PC. I plugged the audio out (lime colored female connector on back of Ubuntu PC) into my stereo receiver's VCR audio in (Red and white jacks), no sound. Yes, the cable is fine (same cable I took off the other PC which was working fine), and the receiver is set to VCR. I recall having to go through some hoops to get the USB speakers working way back when. The Pulseaudio volume control shows left and right pulsating bars when I have on Pandora, but sound is obviously not being sent to the right output. I also tried the optical audio out on the PC into the receiver's DSB optical in but again no sound.
I don't want to monitor my inputs. In other words: My microphone input plays through my speakers, adding a lot of undesirable noise from the mic. I can mute the mic inputs in alsamixer and/or in the Pulse volume control. This works to get the mic out of the speakers--but it also mutes my mic entirely, so I cannot record audio or use Google Talk. I want the microphone muted in my output, but available to my apps.
(I try to get on the Pulse bandwagon but it is so hard--I thought this was exactly what it was supposed to do, give easy mixing control over inputs and outputs. But I have to search for "fixes" with every single Ubuntu release for two years now, ever since it was first included. Ok, venting over, time to get it working!)
I seem to be having a problem with my sound. Every time I start my computer, I hear the sound played at the login screen and the sound played when I login. Right then, every time, the sound cracks up and stops before it finishes. Running "ubuntu-bug audio" shows that ALSA works fine but pulseaudio does not. For reference, "pacmd list" says that there are 0 sinks, 0 sources and 0 caches.
Edit: Solved by a really stupid mistake: loose 3.5mm audio cable. Don't do that. your sound and you're on a desktop computer, go, right now, and check to make sure that you haven't made the same mistake as me.
I installed "Theocracy" on my 9.10 Karmic system. The installer asks for a sound device, dev/dsp is the default and I didn't change it. When I now try to start the game, I get the following error: Unable to open sound device: Device or resource busy Aborted Execution of /usr/games/theocracy_base/theocracy.real failed! What is the sound device when using PulseAudio on Karmic?
Yesterday I decided to remove pulse (mainly because Skype was unable to work with it) but suddenly the sound icon is gone. After some searching on the net I understood that it was part of pulseaudio, but now I feel a bit lost. Alsa works like a charm instead, but since I also want to use ubuntu to record sound I'm not sure if it will work, and also I have a sound source for my HDMI interface and don't know how switch if I want to.

Just like the title says, when I use mpd with pulseaudio, I get no sound but clients appear to be playing (ncmpcpp and gmpc). Other players such as vlc or mplayer work just fine. If I go under the mixer, I get "no application is currently playing or recording audio" under the "Applications" tab when playing through mpd. In contrast, when I'm using mplayer or vlc, both show up in that tab. It behaves as though pulse is simply not configured to work with mpd.Here is my config (edited out any commented line for brevity):
Code:
$ cat /etc/mpd.conf | sed '/#/d' music_directory"/media/data/DM/Genre" playlist_directory"/var/lib/mpd/playlists" db_file"/var/lib/mpd/mpd.db"
I cannot get sound to work with my new installed Opensuse 11.2. If I check yast (sound card configuration), I can play a nice testsound. However, Kde (I am using kde 4.4.2) does not issue any sound at all.
Before I upgraded to 10.10, I would hear sound on both my PC speakers and on my TV. The speakers are connected via the standard speaker out, the TV was connected via the line-out, through a stereo to RCA adapter. Video is supplied to the TV via HDMI. Now that I've upgraded to Maverick, however, I no longer get sound on the TV. This isn't the usual "sound stopped working completely on upgrade" issue, because I get flawless sound via the PC speakers just as before. I've tried most of the debugging steps recommended in other threads about audio, with no improvement.
The weird thing about all this is, when I plug other speakers or headphones into the same port, I hear audio. So I'm starting to suspect that the problem has to do with the HDMI audio out capability on my video card (an nvidia GT 240), which might have suddenly come alive (if not fully functional) with Maverick's new version of ALSA. I don't know what signal(s) my TV thinks it's getting and have no way of troubleshooting things on that side, but it seems possible that the HDMI it's getting video through is also sending a null/silent audio stream, and that stomps the analog audio signal it's getting from my sound card.
I see two output devices in Sound Preferences, "Internal Audio" and "High Definition Audio Controller". "Internal Audio", ie my onboard sound, is what's producing audio via the speakers. HDMI has never produced any audio, and I don't really need it to if I can just make it work the way it did before. I've tried completely disabling that device, even adding the "snd_hda_codec_nvhdmi" module to /etc/modprobe.d/blacklist - no change.
The solution for this could be one of two things: one, I could try to get the HDMI audio out working and let that be what my TV receives, two I try to make the audio setup work as before, with analog audio going to both speakers and TV. Thoughts? I'm leaning towards the latter, ie not bothering with the HDMI audio, as having another audio source would probably mean messing with PulseAudio which has otherwise worked 100% fine for me up until now. If need be I can supply more details on hardware, CLI output etc.
My headset is doing a fine job, using the standard audio connections, but I'd like to be able to use speakers as well. Someone's given me a very basic "soundball" ‒ only visible identification, the word 'goobay' ‒ that's been doing well on another O/S. When I plug it in, it's on speaking terms with the USB port as far as drawing power goes: but doesn't play anything.
The options from Sound preferences don't include anything as obvious as "use USB port/ use audio connectors". Is there an easy answer?
I tried to change to 5.1 from stereo and lost sound entirely. To get sound back I had to uninstall pulseaudio, but that gives me sound only on my right front speaker and sub.Whenever I install pulseaudio again I lose sound all over again.
Rhythmbox plays some music (not all of it) and it sounds crappy. And when I start Amarok I get this: KDE detected that one or more internal sound devices were removed. Do you want KDE to permanently forget about these devices? This is the list of devices KDE thinks can be removed: Output: HDA Intel (INTEL HDMI) Output: HDA Intel, INTEL HDMI (HDMI Audio Output)What to do?
I am using a couple of Debian Distro (Sid and Lenny) add some Ubuntu into the mix. I made the switch because I was amazed and satisfied with Debian --> once installed, everything works. For me that's okay for o so many years now. I don't question a lot because it just works and I do my job on it satisfactorily. Namely programming the LAMP style programming. Lately I have been using Debian to communicate over the internet -- using Skype and Pidgin and other such things, not to mention listening to music, watching movies, just using the default applications when I originally install Debian.
Along the way, I need to configure something -- that is desktop related -- like the screen resolution of a new LCD monitor replacing the old one and such. Now about my sound -- I'm not touching it because it is working. But that is not the case always. Now I have a constant error -- it is irritating. Rhythmbox don't make a sound always when I have open a web browser (iceweasel, chrome, epiphany) and a site with multimedia object on it -- like a video or something. So how do I correct this? How do I know, too what I am using -- ALSA or Pulseaudio?
After updating my kernel my sound stopped working. I followed the sound problems guide in the sticky thread at the top of this forum and I've now got it to the point where I get sound through the headphones but not through the laptop speakers. Here is my sound info (output from alsa-info.sh thingy). I've added various lines to the end of my alsa-base.conf but no luck.
I'm currently running 32-bit Ubuntu 10.04 on a Pentium 4. I'm currently using the LXDE desktop environment but the problem is the same in GNOME. I have new Altec-Lansing BX1220 speakers. They didn't come with a driver disk and a Google search didn't return any drivers, so they should be plug-and-play. When I plug them in, the light turns on, and with the volume high enough it returns feedback. However, they don't actually play what the computer is playing. I went into alsamixer and made sure all the volumes were turned up; it didn't help. It was plugged into my microphone jack.
I have installed 10.04 on my sony vaio, model VPCF115FM, and when I plug in my headphones I can hear sound, but not from the speakers when I unplug the headphones. I have checked the alsamixer to make sure nothing was muted.
Basically, my sound is coming through earphones when plugged in, but not coming through speakers without earphones in. I have followed through the steps of other people with the same problem but no luck.
Just installed Ubuntu 10.10 with Wubi (took forever to figure out how to get the wubi.exe to recognize the 10.10 iso) and I don't have sound coming from my speakers. Audio works fine with headphones, but output from speakers is non-existent.
I get sound when I boot into Windows 7, so I doubt it had something to be with the actual speakers. I'm really new to Ubuntu (but loving it!) so troubleshooting is a little difficult for me, especially with terminal commands.
I replaced the motherboard and now the sound on 11.04 only comes from the headphone jack. however when i boot into bios i can get the bios to beep through speakers. the speakers also do not produce sound on a Ubuntu live CD. Here is my output of lspci so you can see all my hardware inside. p.s. its a laptop dell stidio 1558
I had sound in Jaunty, and I just upgraded to Karmic, and everything else is working 100% ok. Except for sound. I have no sound at all if I use any other driver than OSS. I have pulseaudio installed but it doesn't recognize my sound card.
I installed the pulseaudio equalizer today on my Karmic desktop using the instructions at URL...When I enable the equalizer via the GUI checkbox, my sound instantly becomes garbled. When I disable it the problem disappears, but then I can't use the equalizer, which was the point of the exercise. I found some suggestions about editing /etc/pulse/default.pa, but the parameters concerning module-hal-* don't appear in my default.pa. I also have read through a couple of Audio Troubleshooting guides without finding this particular symptom.
Here is the update to the old thread that somehow disappeared "HOWTO: A52 Encoded 5.1 Surround Sound Awesomeness with PulseAudio and ALSA on Hardy" thread (archived here). See also this bug report.There are two steps here: add the a52 plugin, and tell pulseaudio to use it.
Step 1: Go to a terminal and do the following:
Code: sudo bash echo "pcm.a52 {[code]....
Pulse should come back on its own unless you disabled autospawn.Now pulse should be aware of your digital surround output. Go to System -> Preferences -> Sound. Click on the "Hardware" tab and change the profile to one of the 'Digital Surround 5.1' profiles. Play some sound (I like to test with www.pandora.com) and enjoy!If it doesn't show up, it probably means that alsa didn't create it correctly. To test if alsa sees the a52 device, type:
Code: aplay -D a52:0
If it errors out (audio open error: No such file or directory) then that means it did not like your asound.conf settings. You might learn something by looking at the output of 'sudo alsa reload' or just 'aplay'.[code].....
I have Ubuntu 11.04 installed on my Toshiba Satellite C655 laptop. When I plug my headphones, they sometimes work, they sometimes don't, but that's not the main problem. When they do work, sound also plays out of the speakers. The only solutions I was able to find were for earlier versions, which don't work for 11.04.
I have an HP Pavilion Desktop computer with integrated speakers in the screen. When I do not have any headphones plugged in my headphone jack, sound is coming out of the speakers.When I plug headphones in my headphone jack, sound is coming out of both the speakers and the headphones. I would like for sound to come only from the headphones when they are plugged in.
I recently switched to Ubuntu 9.10 from Fedora 12 because it was giving me problems, but now I've run into some problems with Ubuntu. I really only use my computer for internet and music, and I'm not really able to listen to my music.My computer is an HP Pavillion dv7-3060US laptop, AMD 64bit processor, 4gb ram, ATI Mobility Radeon HD 4530 graphics chip and an ATI chipset (not sure which).
I have an altec lansing speaker configuration, with a built in subwoofer on the bottom. My problem comes that the sound is coming out of the subwoofer, not the actual speakers themself. When I try plugging in an external set of speakers, nothing happens, the sound still plays. Switching the device from "Interal audio analog stereo" to the other choices in my list does nothing (system>preferences>sound is the list im talking about)I'm able to hear music through my subwoofer when using totem music player, but neither rhythmbox nor amarok play any music. amarok doesn't play at all, and rhythm box shows the music is loaded but no sound comes out and it looks like its playing it at 2x speed.
I've attempted to follow the comprehensive audio problems guide here but I get to step 3 and the website isnt the same, so I can't continue.These are the outputs from the first few steps:
Until recently, when connected my laptop to the stereo via audio out, i had sound coming only from the stereo. I don't know why and when exactly this happened, but now when the stereo is connected, i get sound from the laptop speakers and stereo speakers simultaneously.Is this a bug? I'd like to mute only my laptop speakers but haven't figured out how. I've tried every setting in "sound" or "audio" or whatever it's called in english, but to no avail.Any ideas how to turn off the laptop speakers?
In our factory, we used to use a bell system to signal breaks. Well they died. I figured it would be easy to replace those bells with speakers which ran into an Ubuntu box. I would just schedule some cron jobs to play a sound file to signal breaks.
However, I'm not talking about desktop speakers, and here's where the problem is. I only need two speakers. Do I need to run them both into a receiver/amplifier of some kind? Then run that into the back of the PC sound card? The actual speaker setup is where I'm new at. What would be the best way to get 2 (maybe more in future) LOUD speakers, separated by a few hundred feet, to the back of a computer that would control the ringing?
How can I echo the sound from the microphone to the speakers?
I.e., anything that is picked up by the microphone is played on the speakers immediately, without recording anything. Preferably with the ability to increase the volume.
