Limitations and Feature Requests

Limitations and Known Issues

What Volume² does not do, and issues that are currently open. Worth checking before filing a duplicate issue.

Not supported

Feature	Status
ASIO support	Not available.
Swap left/right channels	Not supported. Voicemeeter or a similar tool handles this.
Equalizer / bass boost	Not a feature of Volume². Use the audio driver's control panel or a dedicated tool.
Hiding the Windows 11 system icon	Not possible. The system OSD can still be suppressed — FAQ #8.
Fn keys as hotkeys	Not possible — Fn keys generate no hookable codes (FAQ #6).
Separate hotkeys for several applications at once	One alternative channel only. Tracked in issue #262.
Software dimming overlay instead of DDC brightness	Not available; Volume² changes the monitor's real brightness.
Autorun as program while running as administrator	Not possible in Windows. Use As Task (FAQ #10).
Styling the Windows Settings app to match Volume²	Different application types — Settings is UWP, Volume² is Win32.
Moving sound off headphones without unplugging, on some laptops	If the Windows device manager cannot switch it, the jack switches physically and software cannot override it.
Native MQTT	No MQTT integration. Use the HTTP endpoints — see Scheduler and Remote Access.
Arbitrary remote text commands	Remote access accepts volume and task commands only; there is no "remote command received" scheduler trigger.
Per-device volume memory	Not stored. Use a scheduler task on device change — see Tips and Recipes.

Current behaviour and gaps

These are working as built today, and are common requests:

• Favourites device switching does not loop — clicking past the last device does not return to the first.
• Hotkeys cannot be temporarily disabled — there is no per-hotkey enable/disable checkbox, so a hotkey must be deleted and re-created.
• The tray icon is not configurable — the triangle colour and the digit colour and font are fixed, unlike the OSD progress-bar background colour.
• No active-device indication when both main and alternative device icons are shown in the tray.
• Microphones are muted individually, not all at once.
• The "table" volume method takes values, not percentages, so a fully custom percentage curve cannot be expressed.
• The volume mixer window shows about three applications by default and does not remember its size.
• No "audio enhance" / loudness toggle from the tray icon.
• The "New playback device" notification appears on each default-device change; the NotifyVolumeType user variable affects notifications in this area.

Open issues

• Activation is lost on every PC start on some Store and Steam installations.
• Tray icon distorted at 4K with 150 % scaling.
• WinXPControl tray skin not displayed in 1.1.9.470 on Windows 7 x64, while working in 1.1.9.468.
• Step sound feedback playing on only some steps rather than every step.
• Volume² fails on Windows 7 with 1.1.9.468 when a sound booster is in use.
• The program stops responding after monitor standby on Windows 10 22H2, across versions, portable and installed.
• Sound stays muted when raising volume from zero with the logarithmic method plus both mute options — see Volume Behavior.

If one of these matches your setup, adding a confirmation to the relevant GitHub issue — with the build number, Windows version and the last working build — is more useful than opening a new report.
