I’ve got a beta-quality release of Soundswitch available now.
You can also peruse the source code.
The big changes for 3.0 are as follows:
- Configure Source1 and Source2 via tray icon.
- Select current active sound device from tray icon.
- Single left click of tray icon switches between Source1 and Source2
- Rewrites of core parts to reduce bugs and increase speed.
Please let me know about bugs.
