howdy! I'm running stable channel and I just updated today, and audio via my headphones via the analog jack suddently stopped working. This is pulseaudio, I verified the headphones work when plugged into my phone, and *going back to the previous nixos-rebuild version in grub did not fix it*
<andrewrk>
any ideas to troubleshoot?
<clever>
andrewrk: run alsamixer, switch to the alsa device (not pulse), and check if its muted?
<andrewrk>
pavucontrol recognizes when I plug and unplug the headphone and shows the volume meter responding to sound playback. I tried emitting sound via different applications
<andrewrk>
oh my god. I ran audacity once. could that be the culprit??
<clever>
the alsa behind pulse sometimes goes on mute
<clever>
it can also happen when drivers upgrade
<andrewrk>
alsamixer shows a meter that matches my system volume and responds to the system volume changes
<clever>
headphone may have its own meter, seperate from master
<clever>
try un-mute and turning up various things
<andrewrk>
the speaker channel makes the sound come out of my laptop even though headphones are plugged in
<andrewrk>
the Port dropdown in pavu control mutes speaker / unmutes Headphone (leftmost) and vice versa
<clever>
not sure then
<andrewrk>
thanks for trying
<clever>
did you reboot after doing rollbacks?
<andrewrk>
every time
<clever>
and check alsamixer again, on the older versions?
<andrewrk>
I mean I rolled back by rebooting and selecting a different grub version
<andrewrk>
no, I'll try that now, roll back + check alsamixer
<andrewrk>

I can do QEMU_OPTS="-display none" to get the nixos build-vm output to run headless, but the console isn't connected

alsamixer looks and behaves the same on the older nixos version and the newer one (new one is 20.03.2741.4364ff933eb (Markhor)) not sure how to check the older one without rebooting and looking at grub

you can read the grub.conf in /boot/

I've set up an NFS mount with options = ["x-systemd.automount" "noauto" "x-systemd.idle-timeout=1min"] and the autofs mount that shows up in `mount` does show the option `timeout=60`, but even waiting a few minutes after accessing the mount point, the actual NFS mount is still not unmounted. What am I doing wrong?
<patagonicus3>
For context: I have two machines that are not on all the time. I'd like to have automatic mounts for some NFS shares, but I'd like to automatically unmount them so it doesn't get annoying if the server shuts down before the client.

johanot: In relation to https://github.com/NixOS/nixpkgs/pull/45670. I was wondering. Would it be possible to make `easyCerts` mechanism work synchronously in relation to k8s systemd units? Currently IIUC there is no synchronization happening between them and various k8s systemd units would restart repeatedly until the certs appear on disk in the right locations. This makes tests very noisy and harder to debug than

hi everyone, I'm working on a NixOS configuration where some sub configuration files are being pulled into a master configuration file using an "import" statement. What's a good way to pass some options from the master file down into the sub configuration files? Can these somehow appear in the {config, pkgs, ....} line at the top of the sub config files?
<lassulus>
well the best way is to use options IMHO
<clever>
Henson: you want imports not plain import, then you can use { config, ... }: and just define your own config options

i've just started using nixos and i'm confused about home-manager. i see a lot of recommendations for it, but i'm having trouble determining what it provides if i just want to install user packages and import dotfiles. is there more to it?
karantan has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]

That's basically it. But it allows you to manage your per-user packages yourself.
<{^_^}>
[nixpkgs] @marsam merged pull request #97917 → lefthook: use go 1.14 to build → https://git.io/JU8GM
<chipb>
I guess it probably allows management of user systemd services too. I think of it as nixos-rebuild for your home directory.
<xensky>
judson: so what does it mean to manage those myself? can i not manage per-user packages with just nix?
<chipb>
but then I don't bother with it either.
<chipb>
yes, you can use nix directly as your user.
<judson>
You can e.g. nix-env -iA to install packages for yourself.
<judson>
But where nixos-rebuild will let you e.g. update your whole system, things you've installed imperatively don't get updated that way.

It's very handy to manage your system (and your user environment) declaritively and then update with home-manager switch

I can check the list of environment variables, find setupCompilerEnvironmentPhase and compileBuildDriverPhase, and guess that I'm supposed to run those. But that seems rather ad-hoc.

xensky (chat.freenode.net): if you don't want to switch everything over to rely on home-manager, you can maintain your files separately and have home-manager put them into place for you on your more nix-y systems using something like `xdg.configFile."something/something".source = ./my-dotfiles/.config/something/something`
