 Solus comes with Pipewire configured by default.

+## Pipewire as a JACK Replacement
+
+Install `pipewire-jack` by executing the following command:
+
+```bash
+sudo eopkg it pipewire-jack
+```
+
+Currently, using `pipewire-jack` as a `JACK` replacement is not as smooth as one would think. You need to do some manual configuration to get JACK apps to behave appropriately.
+
+### Issues to be fixed
+
+With no configuration, `pipewire` doesn't switch to the appropriate sample rate for the project.
+

+
+### Configuration
+
+
+1. Open the terminal and input the following commands:
+
+```bash
+cd .config/
+mkdir -p pipewire/pipewire.conf.d/
+sudo cp /usr/share/pipewire/pipewire.conf.avail/10-rates.conf pipewire/pipewire.conf.d/
+sudo cp /usr/share/pipewire/jack.conf pipewire/
+sudo chown yourUserName:yourUserName pipewire/jack.conf pipewire/pipewire.conf.d/10-rates.conf
+```
+
+2. Open the `jack.conf` in your text editor and:
+
+    1. Search for `node.rate`.
+    2. Uncomment `node.rate`.
+    3. Input the sample rate you wish JACK applications to open with after the `1/`.
+    Common rates: 44100, 48000, 88200, 96000.
+
+    Without this Pipewire doesn't dynamically adjust the sample rate for you whenever a JACK application opens.

+
+3. Reboot your system.
+
+:::note
+After applying the configuration, there are delays of up to 2 seconds when beginning to play audio due to the `10-rates.conf` that allows `Pipewire` to change sample rates dynamically. 
+
+After the sample rate is set, there are no delays.

+
+### Not Done Yet
+
+Enable the pro audio sound configuration for our card to avoid pops and crackles (also known as [Xruns](https://alsa.opensrc.org/Xruns)).
+
+**On Budgie**: Install `pavucontrol`.
+
+```bash
+sudo eopkg it pavucontrol
+```
+
+Open `pavucontrol`, go to the **Configuration** tab and select the **Pro Audio** option from the dropdown menu for your card.
+
+![Pavucontrol Config Change](pavu-config.gif)
+
+**On KDE**: Go to the `Audio` section of system settings. Select the **Pro Audio** option from the dropdown menu for your card.
+
+All is done! Happy audio production!!
+
+### Limits
+
+If this is annoying you
+
+![Ardour warning about the limited amount of locked memory](ulimits.png)
+
+You can adjust it by configuring the `limits.conf`. In this case we'll be using the `limits.d` for simplicity.
+
+Input the commands below
+
+```bash
+sudo mkdir -p /etc/security/limits.d/
+echo "@audio   -  memlock    unlimited" | sudo tee -a /etc/security/limits.d/audio.conf
+```
+
+**On Budgie**: Log out and log back in for changes to take effect
+
+**On KDE**: Reboot the system
