So, the only way to have bass is to use PulseAudio and edit daemon.conf to enable-lfe-remixing? Well, damn, but alright. how do I fine-tune low frequency reproduction (since my satellites can't handle anything below 150Hz)?

i have an hp pavilion dv7 and am using f13 64bit. my laptop has a built in woofer underneath that i have never been able to get to work. after the latest kernel update today my laptop now has woofer sound. there must be some new support for my laptops audio card. the problem is that it is a little overbearing. how can i a) disable this feature b) tweak the parameters like crossover frequency or gain? edit: i checked the changelog for 2.6.34 and couldn't find any info on any new audio support features.

I had managed to get rid of it in Fedora 10 with the command: su -c "yum remove alsa-plugins-pulseaudio pulseaudio" I just don't want to have to deal with Pulseaudio anymore. It does not like my sound card and gets in the way. Is there a Linux distribution that does not use Pulseaudio ?

This tutorial is meant for Ubuntu 9.10 Karmic Koala, but it might work in earlier or later versions as well. I wrote this tutorial mostly because it took me a full day of work using lots of help from people on #mpd and #pulseaudio from the FreeNode IRC server.The goal is to get the MPD daemon working using PulseAudio, but without it being dependent on the X server or a session. To do that we must configure PulseAudio to run in system-wide daemon mode (which is not recommended by the developers, but in this case we do not have a choice). This means it will be using the /etc/pulse/system.pa config file instead of the usual /etc/pulse/default.pa. We must also make sure the appropriate user/group permissions are set, or PulseAudio will be rejecting the connections.The result will be an interrupt-less music environment, not dependent on the X server. Meaning we can for example log out and log in without the music having to stop for even a second. Switching TTYs (Ctrl+Alt+Fx) will also keep the music playing (not possible by default). All that and PulseAudio will still be able to detect and configure all your devices automatically.
Instructions: Make sure you add your username to the following system groups: pulse, pulse-access and audio.Do that by going to System --> Administration --> Users and Groups.Click the unlock button (the one with a picture of some keys), then click Manage Groups. In the list of groups that pops up, for each of the previously mentioned groups click "Properties" and select all the users that you want to have this functionality.
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 have a suspicion that this is easily fixed, however a good google (and this forum) hammering having turned up the fix. So I probably have the wrong search criteria, My Gnome Applet for switching CPU Frequency Scaling has 'disappeared' and is not listed in the the Add to Panel.. list of applets.

View 2 Replies View RelatedI'm on 9.10 and I use huludesktop often to watch my Hulu queue. Every once in a while (and more so lately) the video freeze and the sound stutters. I then find that pulseaudio is taking 100% of a CPU (I have a quad core AMD 64bit machine). Killing pulseaudio causes huludesktop to continue without sound and a new pulseaudio starts up. I have to kill huludesktop and resume playback and then everything's OK, until it happens again.
View 4 Replies View RelatedI 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

Execution of /usr/games/theocracy_base/theocracy.real failed!
What is the sound device when using PulseAudio on Karmic?
I need to upgrade Pulseaudio to a version better than 0.9.14 (i.e. at least 0.9.15) in order to get the Pulseaudio plugin in Blueman to work, but despite following these instructions to add the PPA it will not be upgraded!
View 7 Replies View RelatedWhy do this? Two reasons:
1) Many of us use JACK for low-latency audio work, but it's annoying to have to turn it on or off to have to allow regular Ubuntu applications to work. It's even more annoying that both can't normally work together -- either JACK or PulseAudio must take control of the sound control. This method allow JACK to do, and PulseAudio just routes to JACK.
2) JACK is kinda super awesome. By routing PulseAudio through it, your regular Ubuntu sound application suddenly get super powers. Pretty easy to do! (Well, we count our blessings in Linux...)
1. DYNAMICALLY You need the PulseAudio utilities and JACK sink:
Code:
sudo aptitude install pulseaudio-utils pulseaudio-module-jack And then run this to get PulseAudio connected to JACK: Code:pactl load-module module-jack-sink pactl load-module module-jack-source Now, go to Ubuntu's sound preferences, and you'll see "Jack sink" in the output tab. If you use JACK Control, you can create a script for the above and have it set up in "Execute script after Startup". Then, PulseAudio will automatically load the JACK sink when you start JACK.
2. BY DEFAULT Edit /etc/pulse/default.pa, and add these lines:
Code:load-module module-jack-source load-module module-jack-sink You can test it without rebooting by restarting PulseAudio. In Ubuntu, PulseAudio is started in the user session, not as a system daemon. To restart it:
Code:
pulseaudio --kill
pulseaudio --start
So there's just one DVD (Narnia) that won't play on my Ubuntu machine using Totem: other DVDs play (I've installed libdvdread4 and libdvdcss2 like a good boy) and non-pulseaudio players like VLC play it properly. If I completely remove and kill pulseaudio, it plays in totem fine. It gets to the language selection screen and I select English, but as soon as any sound is involved it doesn't play. Clicking Go --> DVD menu causes Totem to hang. I don't want to be uninstalling pulseaudio, and VLC player is a bit complex for the mother.
The output of totem:
Code:
marcus@margit-laptop:~$ totem
libdvdread: Using libdvdcss version 1.2.10 for DVD access
libdvdnav: Using dvdnav version 4.1.3
libdvdread: Using libdvdcss version 1.2.10 for DVD access

Note that before the last line, Totem does absolutely nothing. It just sits their. Like it's trying to devour my soul or something.
Just upgraded to Lucid (32bit), pulse generally seems to work ok: I get sound out, I can see various apps connecting via the Sound Preferences dialog (audacious, flash via alsa interface, etc.), and my mic seems to work fine too.
However, when starting skype (v2.1.0.81 which defaults to pulseaudio if it's running), it isn't able to output any sound and I never see a connection appear in Sound Preferences. Don't really want to force it to use Alsa or anything like that; I'd be fine with pulse if it would just work.
I've tried installing the .deb from the skype site as well as the official ubuntu package, with the same result. Any idea why pulse seems to be working, but skype can't seem to use it properly?
Has anyone managed to stream sound from there computer using pulseaudio and rygel ?
I have rygel installed and that works when i run rygel it appears on the ps3.
I also have pulseaudio with dlna enabled and can select it as an output in the sound preferences.
However pulseaudio does not seem to register its stream with rygel, and i am unsure why my only thought is that the versions are wrong as i noticed rygel has recently change its dbus path.
If anyone else wishs to attempt this installing rygel will make the dlna option tickable in pulse audio device chooser applet then you just need to figure out the part i cannot.
I would love to get this working as my ps3 is plugged into an amp it would mean i can send the music i am playing on my laptop to the amp with out plugging the laptop in with a cable.

I'm having trouble getting pulseaudio to start without gdm/X11.
Briefly, I have a Via C7VCM mini itx system running Ubuntu 9.04
32 bit desktop that I want to run as a timed audio recorder for
a public radio station. The machine's limited in memory and
can't handle more recent installations of Ubuntu, 9.04's sufficient
for my needs.
I'm porting some old code that worked
under Red Hat 7.3. I want the ability to run X11, but normally
gdm/X11 will be disabled. The audio commands I need are aumix,
arecord and sox/play.
When I log in under X11, pulseaudio starts up and everything code...
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.

I'm on Ubuntu 10.04 64bit, and I've got JACK and Pulseaudio both installed, though I don't run them simultaneously. I also have LinuxSampler and Rosegarden, and I have the necessary ALSA drivers. Pulseaudio can output to my external sound card, but JACK doesn't, even if I tell it to. I've seen its full name (Guitar Rig Mobile IO) and chosen it as the output device under Settings, but to no avail. It still sends the output to the internal (and crappy) sound card.

Code:
I'm getting this weird noise and (sometimes) delayed audio on HDMI out on VLC. I've tried banshee, miro, ..... on FF and all of them work just right. I would settle changing VLC's sound output to ALSA, but it's also buggy as I get no audio after pausing. Restarting or reloading Pulseaudio and ALSA didn't work either.
Does anybody have a recommendation? Obviously, I'd like to stick with VLC.
I've got two soundcards in my new machine - Realtek ALC8892 onboard, with headphones plugged in, and an M-Audio Audiophile 192 with speakers. There's also HDMI sound out on the graphics card, but I don't use that.
Audio with PulseAudio's output through the sound card is fine. Audio with PulseAudio's output through the onboard sound is fine. If I set the output to Simultaneous Output, however, I get significant lag. Almost half a second. It's quite distracting.
Is this just a problem with PulseAudio's simultaneous output implementation, or is there a fix that I've overlooked? Running 64-bit Natty, btw.
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 am having a problem with skype that i wasn't having before, and afaik skype hasn't been upgraded recently, so something else presumably has changed.
because of driver issues i have to use an external usb audio interface to do voip. this interface is not connected to the pulseaudio server. i am able to connect it to jackd and it works fine for both audio in and out. however it no longer shows up in the list of sound devices available to skype. this used not to be the case. i have tried stopping and restarting skype, as well as unplugging and reattaching the interface. the interface does not show up in pulseaudio manager in the lists of devices.
sat in an internet cafe with my music on loud using my headphones when my cell phone vibrated and upon taking off my headphones I noticed that pulseaudio was channeling all my music not only to my headphones but also to my regular monitor out!
So I was actually listening to music using my headphones when in fact the sound was LOUD on my laptop speakers...
Is there a way to configure the thing to not do that? I want the sound to be muted as soon as I plug in my headphones.
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.
View 9 Replies View RelatedThe only thing I have found so far which does not work for me after upgrading to 10.04 is the ability to change the master volume via LIRC and the pulseaudio lirc plugin.LIRC itself is working, I can verify it recognizes my remote control input by using irw, and all other portions of my lircrc file are executed correctly, such as my On Screen Display. However, no changes are made to the system volume.
I have already reinstalled the lirc pulseaudio plugin to no avail.Can anyone else confirm if this does/doesn't work on their own system?
