Audio on Linux is a mess

Audio on Linux is a mess

[Fred .]

ALSA lib pulse.c:272:(pulse_connect) PulseAudio: Unable to connect: Timeout
ALSA lib pulse.c:272:(pulse_connect) PulseAudio: Unable to connect: Timeout
AL lib: alsa.c:344: Could not open playback device 'default': Connection refused
AL lib: oss.c:179: Could not open /dev/dsp: Device or resource busy
  File "/var/lib/python-support/python2.5/pyglet/media/drivers/openal/__init__.py",
line 340, in driver_init_device = alc.alcOpenDevice(device_name)

Audio on Linux is a mess.
I launch an Python script that uses audio then it breaks, and when the
Python script is closed, I still hear the audio skipping and repeating
like,
"kakakakakakaka" in infinite loop.
And PulseAudio seems to be frozen.
Then I kill PulseAudio and finally the audio noise stops.

Oh, and I heard OpenAL downsamples stereo to mono on Linux due to a bug.

Whole audio on Linux is just a big mess.

Please behave yourself.
Is there any way we can help you (which I doubt, but ...)?

You got what you paid for.

Maybe if you change your attitude and supply some information, someone might 
consider looking in your issue, othervise it would be a problem since I 
forgot my crystal ball back at home.

1. Pulseaudio issue (or rather the distro who configured pusleaudio 
issue, rather than pulseaudio directly - looks like you have some kind 
of networking issue where or a mismatch in pulseaudio libs but that 
beside the point).

2. OpenAL issue.

Well complaining to the ALSA list when the two things you actually 
complain about is not actually anything to do with alsa is not the right 
way to help fix that "mess".

If you wish to be constructive rather than just random flaming them I'm 
sure people will be happy to help.

I will happily take the time to explain to you why I think the future is 
quite bright for sound on linux (I agree that some degree of mess exists 
just now).

At the moment tho', you have a problem speaking to pulseaudio. You 
should debug that first. If you cannot work it out yourself, ask on 
#pulseaudio or on the pulseaudio mailing lists.
