Hi there,

Im tryin to get my first open source project on the board, and with so MANY things I would like contribute to, I thought I would start with a rock. Computer Games. I love Spring, but the sound simply doesnt work with PA. Now ive read (really quite a lot) of posts you have made about glitch free, etc, and Spring RTS has an ubunutu repo and all that.

So here's the issue. Spring connects through ALSA plugin to pulse audio. Works, sort of... and then (very soon) there comes a LOUD stutter grainy greating noise, intermittently filled by perfect audio.
So I open the Pavu volume control... Wierd. Spring is there (ALSA Plugin (spring)) however during the periods that it is noisy, its entry in the playing tab flickers. Spring is being dismissed/reattached to pulse in a kind of dance of the sugar plum graters.

Im sure this is something to do with how spring is ... pfft.. nope im not sure of anything. Do you have any ideas. Id love to contribute to the Spring codebase and this would be inline with ubuntu/gnome/repos/LINUX yey

p.s. also skype [edit: (through PA)] still crashes my sound card intermittently [edit: (like the the mike hard crashes and I have to turn my machine OFF to get it to work again)], and in koala i do not have a single player that syncs a/v except totem. pfft, pfft and PFTT again!

I run Ubuntu 9.10. I followed your instructions and still I have no microphone.
Also, I use a USB phone for Skype and every time I have to go to Sound Preferences and choose the USB phone as an output and input to use it with Skype. At the end of a call if I want to listen to music I have to go back to Sound Preferences and Choose the internal Audio output.
Is there a way to select one thing for Skype totally independent of the rest of the system so I do not have to go back and forth?
Thank you,
ierotheo

Hello,
Does anyone know any workarounds for the following bug/issue:

The application does not play audio and does list an entry in the Playback tab; the application is using PulseAudio but there is a problem, such as: a bug in PulseAudio, a problem with your ALSA kernel module or libraries, or your PCM/Master volume is muted.

I finally got pulse up and running, but now i'm stumped. I'm pretty new to all this, don't know how to check my ALSA kernel module for problems, for example.

Volume control is not muted, and lists a single "dummy output."
My soundcard is a Hoontech DSP24, 8-in, 8-out.
Alsamixer displays all inputs and outputs. HW 0-7 for example defaults PCM Out and have no volume control or mute options.
I managed to get the sound to work once, but only for Rhythmbox, and only that once. No idea. Can anyone help??
Thanks,
Keith

I used this from the original thread on a Laptop I bought
11/24/09 a HP G71-34US and it is the only one that made my
Intel sound card work after hours of looking and trying.
I decided to put another partition of Ubuntu for 10.04 so I
can keep one stable and one testing this time.
I lost this web page and I had to hunt forever and when I put
in the Karmic fix I will be darned if it did not work again.
It acts like it doe's not have a chance to work and then bingo
noise from my speakers. I will not lose this Thread again. I was up
all night looking for something to work again. Sound problems are
so baffling. Look at this Grub went nuts last night and wiped it
and started over in a fit of energy. Partitioning software is so
good now. The only thing that stops me from doing more is the size of the boot menu gets so long when you get a couple of different Linux kernels for each partition.
Anyway I sure am greatfull for this fix for my sound.

All this guide did was show me how to crash my audio.

Thanks for the tutorial. I am having problems with mplayer. On a stock install, mplayer just wouldn't work, due to some pulseaudio connection refused problem. I solved it by using -ao alsa. Now after using your tutorial, none of the methods seems to work I get proper sound in firefox/flash, but now mplayer is borked I can't use amarok either, it says - "xine: unable to initialize any audio drivers".

Here is the (relevant) mplayer output:

rohan@ubuntu:/media/sda6/Fav_songs/Hindi$ mplayer Saher/Palkein\ Jhukaao\ Na.mp3 -ao pulse

I am using Kubuntu, and not Ubuntu, does that make any difference? I know I can roll back all the changes, but somehow what you've done seems correct, so I don't want to roll back. Is this a problem specific to my system?

Kubuntu can't use this equalizer. The volume should be fine in kubuntu by disabling it. This script only works with ubuntu, as far as I know.

Again, it doesn't work in xubuntu either; just the normal gnome based ubuntu
