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 doesn't contain libasound_module_ctl_pulse.so

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---

--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

Thank you, I modified it to keep the 'pulseaudio? #f' function, and
pushed :-)
