scream VS firejail

Not sure about NixOS specifically, but I'm pretty sure Scream is the widely accepted audio passthrough solution for Windows VMs.

I had a situation where there was a lot of noise on any usb connection from my PC to my DAC, but no noise on the usb from my jetson nano (similar to a raspberry pi). I set up a wireless audio interface between them using a project called Scream, so I could play audio on my PC and have it come out the usb port of the jetson. It creates a virtual sound card on the windows side, meaning you can send any/all audio from any source on the pc, which I think is what you're looking for. Warning, it was a pretty involved process and the final results were imperfect, it worked great 99% of the time but had weird pops and stutters 1% of the time.

Have you tried scream (with or without IVSHMEM)?

Hello all. I'm trying to send audio from my windows desktop pc to my linux mint laptop over an ethernet cable connected betwen the two machines as I don't have a router near them (I'm using wifi in both). I found this SCREAM tool to take the audio from the windows pc to the network but I'm not a networks expert at all. I wanna know if what I'm trying to do is even possible and if so, how can I set my linux to get the audio and play it on my headphones. Thanks.

Solved with Scream https://github.com/duncanthrax/scream

So thats really strange, so maybe try Scream audio it's on github with documentation https://github.com/duncanthrax/scream

How does connecting sound in pulseaudio compare to scream?

bubblewrap is designed as a low-level too. There is nothing quick and dirty about it. It disallows everything by default and you have to be explicit about what you want to share with the host. If your application needs complex permissions/resources, then you will need to have a complex bubblewrap command line.

Once you have figured out which permissions/resources you need for a given program, you can wrap the command line invocation in a shell script.

If you want other people to do the work of defining permissions/resources, then have a look at firejail: https://github.com/netblue30/firejail

Firejail is cool: https://github.com/netblue30/firejail

Linux namespaces/cgroups but nowhere near as heavy as Docker.

I use it when I want to limit the memory of a Python script:

```

Firejail can also be a useful option, though no good if you're on Mac https://firejail.wordpress.com/

Uses the same Linux primitives as docker etc, but can be a bit more ergonomic for this use case

Firejail, Flatpak (which uses Bubblewrap under the hood), and Snap (which uses AppArmor) all use the same underlying technology: Linux namespaces.

This question comes up a lot, and has been answered here: https://github.com/netblue30/firejail/wiki/Frequently-Asked-...

TL;DR: Firejail has much more comprehensive features than Flatpak (Bubblewrap). Firejail also has more comprehensive network support, support for AppArmor and SELinux, and easier seccomp filtering.

Compared to Snap (which uses AppArmor), Firejail is compatible with AppArmor and again goes above and beyond with a lot of additional features.

Wonderful little tool, too bad you must chain various exec calling tools to get cgroups (a bit akin to `ionice ... nice ... cmd`) and Linux users namespaces can't allow UNIX sockets while preventing network access (I think?).

Migrated from Firejail when its complexity annoyed me too much and I hit https://github.com/netblue30/firejail/issues/3001 (Firejail doesn't like parens or brackets in --put/--get parameters) to a badly NIH version using bwrap and bash to have "profiles":

Firejail does this. The profile database is the two "profile" directories in https://github.com/netblue30/firejail/tree/master/etc

What do you mean by a Firefox container? Do you mean FireJail?
