Hello Nathan,

can not possibly work. The reason for that, is that "file" does not
refer to an actual file, but to a file-like object as returned by Guix
G-Expressions. You probably want to use `mixed-text-file' or something
similar to write your default.pa inside Guix itself. Alternatively,
you can unset PULSE_CONFIG and PULSE_CLIENTCONFIG in your .profile (or
equivalent for other shells) and Pulseaudio should load your local
configuration.

Regards, Leo

mixed-text-file allows you to split the string into multiple parts, but
that is essentially the idea, yes. There are of course other ways of
building it, but it is your task to ensure, that those end up with the
result you want. In my personal opinion, explicit coding tends to be
best suited to accomplish this.

That should work up to a certain extent – what this basically does is
copy your local default.pa into the Guix store and then
/etc/pulse/default.pa is a symlink to that file in the Guix store.
Depending on the content of default.pa, that may not actually be what
you want, but unless you're doing very weird things in there, it may
also be a perfectly valid configuration.
Can you check, that /etc/pulse/default.pa is indeed what you want it to
be? IIRC, you may have to reboot for /etc to change.

I don't think so. The relevant code portions are in
gnu/services/sound.scm and read among others:

(define pulseaudio-environment
(match-lambda
(($ <pulseaudio-configuration> client-conf daemon-conf
default-script-file)
`(("PULSE_CONFIG" . ,(apply mixed-text-file "daemon.conf"
"default-script-file = "
default-script-file "\n"
(map pulseaudio-conf-entry
daemon-conf)))
("PULSE_CLIENTCONFIG" . ,(apply mixed-text-file "client.conf"
(map pulseaudio-conf-entry
client-conf)))))))

Due to a bug with webkit sandboxing, we no longer put daemon.conf into
/etc/pulse (my bad), but rather set PULSE_CONFIG to directly point to
it. As you can see, `default-script-file' should be set to the file
you're supplying. I am currently unsure, at which point this variable
gets updated (I still think you need to reboot), but I'm pretty
convinced, this would work with a custom script file.

Regards,
Leo.

That might be an issue, but your $PULSE_CONFIG should at least point to
the right default.pa. It should especially not be the daemon.conf
shipped with pulseaudio, because we override flat-volumes (which most
distros agree has an insane default).

Btw. please keep the bug in your reply, so that others can follow. The
easiest way of doing so is to use "reply to all" in your mail client.

ok $PULSE_CONFIG points to daemon.conf which points to my edited file.

This should not be a problem. JACK2 only differs for users but not in
terms of the API when building software. In Guix we only build with
JACK1 for consistency.

So if I disable pulseaudio autostart, and start it from bash, I get these errors

bash-5.0$ pulseaudio
E: [pulseaudio] module-jack-sink.c: jack_client_open() failed.
E: [pulseaudio] module.c: Failed to load module "module-jack-sink"
(argument: ""): initialization failed.
E: [pulseaudio] module-jack-source.c: jack_client_open() failed.
E: [pulseaudio] module.c: Failed to load module "module-jack-source"
(argument: ""): initialization failed.

So pulseaudio is seeing my settings correctly, but some other problem
is preventing it from working.

Seems the original issue got understood, but you still have some
configuration problem to tackle.

Closing this old forgotten issue, although note that the recently
introduce 'extra-script-files' field of the pulseaudio-configuration may
be useful to what you are/were trying to achieve.

Thanks,

Maxim
