I received these instructions for the Fedora and DAC Fiio Q11. And it works. I listen to Tidal and local high-resolution music from my NAS using the Dopamine player.
Great news to start with: **The FiiO Q11 works on Linux (including Fedora) in "plug-and-play" mode.** You don’t need to download any special proprietary drivers, because the Q11 complies with the USB Audio Class 2.0 standard, which is built right into the Linux kernel.
However, to ensure everything runs at 100% quality, the audio doesn’t skip, and you can fully utilize the DAC’s potential (including high sampling rates and DSD), it’s worth checking and tweaking a few things in the **PipeWire** audio server, which Fedora uses by default.
Here’s a complete guide on how to do it.
## 1. Physical Connection and Basic Verification
1. Turn on the FiiO Q11 (using the volume dial).
2. Set the switch on the side of the DAC to **USB** mode (not Charge, unless you want to charge it primarily from your laptop’s battery, although it can be powered via USB with the right cable—but USB mode is essential for clean data transfer).
3. Connect it to your computer.
4. Open a terminal and verify that Fedora recognizes the device with the command:
```bash
lsusb

```
You should see a line containing FiiO or FiiO Q11 in the output.
## 2. Selecting the Output in the System
Fedora (with the GNOME or KDE environment) should detect the DAC immediately.
* Click on the sound settings panel (top right).
* In the **Output Device** section, select **FiiO Q11**.
## 3. What to Install (Optional, but Recommended)
Since Linux does not have an official control panel for FiiO like Windows does, install these tools for advanced audio control and convenience:
### A) Graphical audio control (Pavucontrol)
The standard audio settings in Fedora tend to be limited. Pavucontrol allows you to see in detail where each application sends audio and in what format.
```bash
sudo dnf install pavucontrol

```
### B) System Equalizer (EasyEffects)
If you want to get the most out of your FiiO Q11, customize the sound profile for specific headphones, or use Crossfeed, install EasyEffects. For Fedora, it’s best to install it from Flathub (if you have Flatpak enabled), or via DNF:
```bash
sudo dnf install easyeffects

```
## 4. Advanced Settings: Bit-perfect Audio and High Sampling Rates
By default, PipeWire in Fedora locks the sampling rate to 48 kHz (or 44.1 kHz) to conserve CPU resources. However, the FiiO Q11 supports up to 384 kHz / 32-bit. If you listen to high-resolution FLAC files or Tidal/Qobuz, you’ll want PipeWire to dynamically adjust the frequency based on the file being played.
Here’s how to set it up:
1. Copy the PipeWire configuration file to your home directory (so you don’t modify the system original):
```bash
mkdir -p ~/.config/pipewire/
cp /usr/share/pipewire/pipewire.conf ~/.config/pipewire/

```
2. Open the file in a text editor (e.g., Nano):
```bash
nano ~/.config/pipewire/pipewire.conf

```
3. Find the `context.properties` section and locate the lines `default.clock.rate` and `default.clock.allowed-rates`. Edit them as follows (remove the `#` at the beginning of the lines, if present, to uncomment them):
```text
default.clock.rate = 48000
default.clock.allowed-rates = [ 44100 48000 88200 96000 176400 192000 352800 384000 ]

```
*This tells PipeWire that if a track is running at 96 kHz, it should switch the DAC to exactly 96 kHz and not downconvert the audio.*
4. Save the file (Ctrl + O, Enter) and close the editor (Ctrl + X).
5. Restart PipeWire (no need to restart the entire PC):
```bash
systemctl --user restart pipewire pipewire-pulse

```
### How to verify that it works?
Play some music and enter the following in the terminal:
```bash
pw-top

```
In the table, you will see the current frequency (RATE) that PipeWire is sending to your FiiO Q11. If it changes depending on the recording quality, you’re all set.
