Proposal pages help us get from feature requests into actual plans. This page is a proposal to detect changes in devices as they happen, e.g. plugging in or out a USB audio device.
Proposal pages are used on an ongoing basis by the Audacity development team and are open to edits from visitors to the wiki. They are a good way to get community feedback on a proposal.

  • Note: Proposals for Google Summer of Code projects are significantly different in structure, are submitted via Google's web app and may or may not have a corresponding proposal page.

The Problem

When a new device is plugged in after Audacity has started, Audacity does not detect it.

  • You have to explicitly request a rescan.
  • This is not just a USB problem.
    • Some headphone-or-microphone jacks detect plug-in or removal of a device.

This issue was in bugzilla as Bug 41

Proposed Features

  • Rescan devices when the relevant dialog is opened, if they have not been scanned in the last 5 seconds.
