X7 Control

The Sound Blaster X7 on Linux, fully controlled. Creative’s phone app for the X7 is gone and there was never a Linux one. X7 Control talks to the X7 over Bluetooth with the same protocol the app used, so every setting inside the box is yours again, and it adds the PC-side audio tools Windows users had, as PipeWire filters.

Headphone EQ page with the live response graph

On the X7 itself

Output routing: headphones, stereo speakers, 5.1 speakers
Master volume in dB and the knob-press mute (the usual reason an X7 “goes silent”)
SBX Pro Studio: Surround, Crystalizer, Bass, Smart Volume, Dialog Plus
The X7’s own 10-band graphic EQ with presets and a live response graph
CrystalVoice: noise reduction, voice focus, mic smart volume, echo cancellation, mic EQ, voice FX
Firmware switches: direct mode, headphone high gain, SPDIF-in direct, hi-res USB, auto sleep

On the PC (PipeWire)

Outputs page for every output on the machine, not just the X7: friendly names, volume, one-click switching, and a parametric EQ per output (AutoEq import for headphones, REW import for speaker and room correction), each with a live frequency-response graph and plain-language explanations for people new to equalizers
Per-output sample format, rate, dither and never-suspend settings, with a warning when a digital link runs at low software volume
Optional 7.1 HRTF game surround sink
Optional voice-only microphone (RNNoise) that gates out keyboard, fans and room noise
x7ctl, a small command-line tool for scripts and keybindings

Install

Packages on the release page: .deb for Debian 13 / Ubuntu 24.04 and newer, .rpm for Fedora 40 and newer, .pkg.tar.zst for Arch, CachyOS and Manjaro. Anything else: sudo make install from the source tarball.

Then hold the X7’s Power/Bluetooth button until it blinks blue and press Pair… in the app.
