 |
|
app-emulation/emul-linux-x86-soundlibs-20120520's alsa won't work with pulseaudio (the older version works).
It seems /usr/lib32/libasound.so tries to load a 64-bit module. Tested with 32-bit wine and 32-bit aplay (alsa-utils).
| Code: |
ALSA lib conf.c:3314:(snd_config_hooks_call) Cannot open shared library /usr/lib/alsa-lib/libasound_module_conf_pulse.so
ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM default
|
Worked around by removing /usr/share/alsa/alsa.conf.d/51-pulseaudio-probe.conf and having this in /etc/asound.conf
| Code: |
pcm.pulse {
type pulse
}
ctl.pulse {
type pulse
}
pcm.!default {
type pulse
}
ctl.!default {
type pulse
}
|
The removal of 51-pulseaudio-probe.conf makes alsa not try to load a module and asound.conf forces it to use pulseaudio. However this hack doesn't work if I don't have a running pulseaudio. |

| Because I want to hear sound from a game AND listen to music at the same time. |

See my sig for an example ALSA config. Why hasn't everyone in the world seen this by now?

Because the presentation is crappy and there's no solution for that problem.
Furthermore most of the link of your crappy draft are broken, or the "solution" are already included in the base installation, or aren't applicable.
For your font thing, it's not an howto: it's a pain to read through 25 pages of forum. And there's no straight foward solutions ...
You find it faster by typing "gentoo fonts" in google.
The solution presented in the Gentoo wiki works better ...
Anyways ...
Got the same problem, and did found the solution here.
There you go for Gentoo (tested and working) :
0. Install, if not done, emul-linux-x86-soundlibs
emerge emul-linux-x86-soundlibs
1. Create /etc/ld.so.conf.d/alsa32.conf with the following contents:
| Code: | | /usr/lib32/alsa-lib |
2. Create /etc/ld.so.conf.d/alsa64.conf with the following contents:
3. ldconfig
4. Open /usr/share/alsa/alsa.conf.d/51-pulseaudio-probe.conf in the editor and remove the "/usr/lib/alsa-lib/" prefix from the libasound_module_conf_pulse.so file.
like this :
| Code: | # PulseAudio alsa plugin configuration file to set the pulseaudio plugin as
# default output for applications using alsa when pulseaudio is running.
hook_func.pulse_load_if_running {
#replace this
# lib "/usr/lib/alsa-lib/libasound_module_conf_pulse.so"
#by this :
lib "libasound_module_conf_pulse.so"
func "conf_pulse_hook_load_if_running"
}
@hooks [
{
func pulse_load_if_running
files [
"/usr/share/alsa/pulse-default.conf"
"/etc/asound.conf"
"~/.asoundrc"
]
errors false
}
]
|
And that should do it. |

Thanks Neskweek!
I spent 4 hours already looking for a solution to this problem, so that Europa Universalis IV could work with sound on linux.
Works out of the box now! 
Cheers! |
