[Message part 1 (text/plain, inline)]

Hello Guix,

The alsa-service-type service produces /etc/asound.conf with content:
--8<---------------cut here---------------start------------->8---
# Generated by 'alsa-service'.

# Use PulseAudio by default
pcm.!default {
  type pulse
  fallback "sysdefault"
  hint {
    show on
    description "Default ALSA Output (currently PulseAudio Sound Server)"
  }
}

ctl.!default {
  type pulse
  fallback "sysdefault"
}
--8<---------------cut here---------------end--------------->8---

This config brokes alsamixer utility (removing asound.conf fixes issue):

$ alsamixer
--8<---------------cut here---------------start------------->8---
ALSA lib dlmisc.c:287:(snd1_dlobj_cache_get) Cannot open shared library /gnu/store/98fa0av6rsj9kzrhdw45n9k53gp0d4dg-alsa-lib-1.1.6/lib/alsa-lib/libasound_module_ctl_pulse.so ((null): /gnu/store/98fa0av6rsj9kzrhdw45n9k53gp0d4dg-alsa-lib-1.1.6/lib/alsa-lib/libasound_module_ctl_pulse.so: cannot open shared object file: No such file or directory)

--8<---------------cut here---------------end--------------->8---

alsa-lib doesn't contain libasound_module_ctl_pulse.so

$ find /gnu/store/98fa0av6rsj9kzrhdw45n9k53gp0d4dg-alsa-lib-1.1.6/lib
--8<---------------cut here---------------start------------->8---

--8<---------------cut here---------------end--------------->8---

but alsa-plugins:pulseaudio does

$ find /gnu/store/cfz7jvkzp3k2ginvzz35pyp7zffabksk-alsa-plugins-1.1.6-pulseaudio | grep libasound_module_ctl_pulse.so
--8<---------------cut here---------------start------------->8---
/gnu/store/cfz7jvkzp3k2ginvzz35pyp7zffabksk-alsa-plugins-1.1.6-pulseaudio/lib/alsa-lib/libasound_module_ctl_pulse.so
--8<---------------cut here---------------end--------------->8---

Still after install alsa-utils and alsa-plugins:pulseaudio in my user
profile (I also have alsamixer in system profile), alsamixer cannot find
libasound_module_ctl_pulse.so

Oleg.
