Check the audio path
Start playback yourself and check player, tab and device volume. Make sure the output is not a previously connected headset, Bluetooth speaker or car system. If every station is silent, begin with these shared conditions.
Compare another station
If just one source fails, it may be offline, restrict access or use a format the browser cannot play. A successful catalogue check is historical evidence, not a permanent guarantee. An HTTP source may be blocked on an HTTPS page.
Investigate interruptions
Observe whether playback stops after a few seconds, on a network switch or only after screen lock. Try a stable connection and keep the page visible for comparison. Do not change several settings at once; note what actually changes the result.
Report useful observations
Include the station name, time, device, browser and exact symptom. Share the visible error and whether another station worked. Never include passwords or secret broadcasting keys. Real playback is connected here, while studio broadcasts and calls remain demonstrations.
Does a catalogue entry guarantee the station is online?
No. Streams can change or become unavailable after a check. Your device and connection also affect access.
Should I immediately reinstall my browser?
Start with simpler comparisons: volume, output, another station and a stable connection. These tests identify the scope without changing unrelated settings.
