Hello, after some hours of searching... I found that we can use the
'lib' option in 'pcm_type' and 'ctl_type' to specify the library path
for alsa plugins, e.g:
--8<---------------cut here---------------start------------->8---
# Use PulseAudio by default
pcm_type.pulse {
lib "/gnu/store/icvba55494j4vxb7yp97iya1h6g1l30h-alsa-plugins-1.1.6-pulseaudio/lib/alsa-lib/libasound_module_pcm_pulse.so"
}
ctl_type.pulse {
lib "/gnu/store/icvba55494j4vxb7yp97iya1h6g1l30h-alsa-plugins-1.1.6-pulseaudio/lib/alsa-lib/libasound_module_ctl_pulse.so"
}
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---
So I think we can make our 'alsa-service' do this, instead of patching
alsa-lib for 'ALSA_PLUGIN_DIR'. We could document it in the manual, so
that a user wanting to use other alsa plugins get a hint to add:
'lib "/home/xxx/.guix-profile/lib/alsa-lib/libasound_xxx.so"'
in '~/.asoundrc'. How's this sound?
Also, NixOS did this actually, and they went far to support running
32-bit alsa applications with 64-bit pulseaudio:
https://github.com/NixOS/nixpkgs/commit/0c8ad65560fa1df07ea7b7937e02b44b1ce2b498
I think we don't need this now...
