CicloHub sends audio through HDMI to your screen — and from there to your studio sound system. So sound can fail at three points: the box, the screen, or the sound system.
Check in this order
1. CicloHub / Android TV
Use the CicloHub remote to check the volume isn't muted or at zero.
Restart the CicloStudio app if recent changes haven't taken effect.
2. Screen / TV
If audio is routed through HDMI to the TV → TV speakers / soundbar, check the TV's volume and HDMI audio output.
Some TVs have an audio output setting (HDMI ARC vs Optical vs TV speakers) — make sure it matches your wiring.
3. Studio sound system
If the studio sound system is connected via HiFi digital audio, check that connection and the amp/receiver volume.
Try a different source (a phone connected to the same input) to confirm whether the sound system itself is working.
Best-practice setup
Set the CicloHub output volume to a fixed comfortable level (e.g. 70%).
Adjust the rest with your studio sound system — that gives consistent quality and avoids clipping.
Alternative: rider headphones
Music can also be delivered directly to riders' phones via the CicloZone app. Riders use their own headphones — useful as a backup or for early-morning quiet hours.
