- Fixed HTTP method mismatch: /playNotification endpoint expects GET, not POST
- Updated PlayNotificationBeep() to use existing c.get() method with StationResponse model
- Resolves HTTP 400 errors when using 'soundtouch-cli sp beep' command
- Verified working with SoundTouch 20 hardware
- Added comprehensive troubleshooting documentation
- Updated feature history with bug fix details
Fixes: go run ./cmd/soundtouch-cli --host <device> sp beep
Previously failed with: 'API request failed with status 400'
Now works correctly alongside: curl http://<device>:8090/playNotification
