Can you change this icon (and label) from Headphones to Speakers?

You can rename the entry, but the Quick Settings icon is controlled separately. Open Settings > System > Sound > More sound settings, select the Playback tab, double-click “Headphones (High Definition Audio Device),” and on the General tab replace the name with “Speakers,” then choose Apply. That changes the friendly label only. The headphone glyph in the taskbar output list is derived from the audio endpoint’s form factor, which the audio driver reports; changing the Sound icon may not change this Quick Settings glyph. Because your screenshot shows Microsoft’s generic “High Definition Audio Device” endpoint, install the audio driver from the PC or motherboard manufacturer, restart, and check its audio console for connector or jack-retasking options. Choose Speakers only if speakers are actually connected to that jack. If the OEM driver provides no retasking control, leave the icon as-is and avoid registry edits; the label can still identify the output.

Changing the icon specifically from a headphone to a speaker icon isn't straightforward in Windows 11 and usually involves registry tweaks or third-party tools. Renaming the device in sound settings is simpler but may not change the icon.

 Its name can be changed, but the icon in the sound-output flyout is normally chosen by the audio driver and cannot be manually changed through a supported Windows setting.

Open Settings > System > Sound, select Headphones (High Definition Audio Device) under Output, and use Rename to change the label to Speakers. On builds where Rename is not shown there, press Win + R, run mmsys.cpl, open the Playback tab, select the device, choose Properties, and change the name on the General tab.

If physical speakers are connected and the headphone icon is incorrect, install the latest audio driver from the PC or motherboard manufacturer rather than relying on the generic High Definition Audio Device driver. The manufacturer’s audio utility may also identify the output jack correctly after the driver is installed. The icon itself does not affect audio quality or device functionality, so registry or system-icon changes are not worth using for this.
