Hi,
I have a file with the following contents:
# This file an alsa configuration file, used by pasuspender to make the
# "default" Alsa device work while PulseAudio is in suspended state.
# Include the system configuration first. Is there any easier way to do this?
# 14 lines for including one file is a bit much...

        {
                func load
                files [
                        {
                                @func concat
                                strings [
                                        { @func datadir }
                                        "/alsa.conf"
                                ]
                        }
                ]
        }

# Redefine "default" to be the same as "sysdefault". On most systems

pcm.!default sysdefault
That doesn't do what I want it to do. When I run
ALSA_CONFIG_PATH=/path/to/file.conf aplay -Ddefault ~/test.wav

Doesn't ALSA_CONFIG_PATH=/path/to/file.conf:/usr/share/alsa/alsa.conf
work?
I didn't know that I can give multiple files, so I haven't tried. One
minor problem with this approach is that the alsa.conf path would be
hardcoded, instead of using $(datadir)/alsa.conf.
...
$ALSA_CONFIG_PATH overrides the whole default paths, so it
doesn't include even sysdefault definition unless you specify multiple
paths.
Yes, but did you miss the part entirely where I load alsa.conf in the
beginning of the custom configuration file? That should work too, right?
Ah, OK, I somehow didn't think of that part.
Essentially, the oneliner below replaces the 14 lines :)
confdir:alsa.conf
pcm.!default sysdefault
