  Well I kinda asked about i3 related problems not just generic linux desktop voes but I'll try my best.

  > - I recently bought a monitor and plugged it in. Sound stopped working until I rebooted. Figured it out easily with pavucontrol of course (just toggling things) but only after reboot. Annoying but fair enough.

  And that isn't a problem under GNOME ? Both use Pulseaudio...

  Anyway I ended up resorting to writing some custom udev rules and some horrible hacks [0] to get my sound interface to work correctly; the interface was 2 in/4 out but it showed up as stereo in/4.0 out, and I needed dual mono + dual stereo outs. But as pulseaudio have no memory whatsoever on plugin config, it needs to be reapplied any time device is plugged in...

  ...and after upgrade ALSA of all things horribly broke it in different way [1], where someone added 500ms latency to default profile used to split device into sub-channels to"fix cracking" (that happened to only some users), and the interface I used was assigned that profile

  Linux Sound story is by far my least liked part of it. And the new modern pipewire just hangs on my machine, not accepting any commands...

  > Connecting/disconnecting monitors is flaky, sometimes it requires a few toggles in arandr (which already helps a lot). Maybe there is a better tool I could use?

  I so far only experienced it with one flaky monitor at work, it looks like some deeply rooted problem. I guess if I had to solve it I'd just make some script trying to apply the profile and bind it to keys to quickly fix it. I don't think arandr is the culprit here, rather something between graphics server, driver, and monitor.

  > Some wifi networks sometimes dont' work out of the box even though I'm just using the easy nm-applet.

  I didn't had that problem in particular on laptop at least (also using nm-applet), but same thing works under GNOME ? IIRC it also uses network manager. We had some problems with users trying to use networkmanager for VPN and it not supporting all options plain OpenVPN did.

  The most grief that networking gave me is actually systemd-resolved [2] but no good fix for that so far.

• I have a crazy idea: lets build a Steam Deck based Laptop.
  1 project | /r/SteamDeck | 29 Apr 2023

  But on the flip-side, if you don't use SteamOS, it's a lot of effort to cobble together all the optimizations that make the Steam Deck great (not just the custom kernel--as you can now use the mainline kernel and a quick patch), but the TDP/clock/fps limiters you can slide up and down from that side menu.

• USB Audio (HyperX DuoCast) Microphone record volume is too low
  1 project | /r/linuxaudio | 26 Apr 2023

  Yes. I am using omni directional. Fixed here: https://github.com/alsa-project/alsa-ucm-conf/issues/308

• Running Windows plugins on Linux
  1 project | /r/Reaper | 21 Apr 2023

  I have the MOTU M2 on Manjaro Linux and it works fine through Jack. I know there were some issues with having it recognized under Pulseaudio (here and here), but I think those have been fixed. I sometimes have to power cycle the M2 before it's recognized under Pulseaudio again.

• Microphone not working with Realtek ALC4080
  1 project | /r/archlinux | 6 Jan 2023

  Googling the issue I found I'm not the only one with issues surrounding that chip. I came across this issue, which led me to add my specific device ID (of course it's different for each model 🤦) to my /usr/share/alsa/ucm2/USB-Audio/USB-Audio.conf, without notable effect. Yes I rebooted. I also came across this PR, but I haven't been able to figure out if there's a change I can make to my local files that would make the ALC4080-HiFi driver feel responsible for this USB device, if it's even relevant.

• Weird case of MOTU M4, why it is constantly changing, what to do with the last reincarnation?
  1 project | /r/linuxaudio | 29 Nov 2022

  Most probably something todo with recent alsa ucm changes for M4:https://github.com/alsa-project/alsa-ucm-conf/blob/master/ucm2/USB-Audio/MOTU/M4.conf If changing profiles in pavucontrol on Configuration tab does not help, you can try to disable ucm: https://wiki.archlinux.org/title/PipeWire#Microphone_is_not_detected_by_PipeWire

• Scarlett 4i4 headphone output

• Well, here we go again
  1 project | /r/linuxmasterrace | 5 Oct 2022

  I've had a kernel update break my sound card, alsa-ucm break my sound card and I also experienced the grub problem, which was a pain. I update yesterday and now OpenCL is broken for what I needed it for (hashcat). None I can blame on Arch, it just happens when you get new stuff. Fedora also updated to those packages that broke my sound card, which is typically my Fedora experience after switching from Arch. You get the same bugs.. just a bit later. Not sure what I'll even try now.
