Loxone Audioserver no sound: why music won't play and how to fix it

Open the Loxone app, tap the music icon, and confirm you selected the correct room or zone. It's easy to tap an adjacent zone by mistake.

Check the volume slider for that zone. If it was muted or turned all the way down during a previous session, it stays that way until you raise it.

Confirm a source is actually assigned and playing, an idle zone with no active source will stay silent even at full volume.

Try a different source (for example switch from a streaming service to a local input) to rule out a source-specific problem.

Check that the room's amplifier or the Audioserver's zone output has power, a powered-off amp will show as connected in the app but produce no sound.

Verify the speaker zone hasn't been reassigned to a different output during a recent configuration change.

Test another zone on the same Audioserver. If every zone is silent, the problem is more likely with the Audioserver or amp itself than with one room.

If only one zone is affected and everything above checks out, the speaker wiring or the amp channel for that zone may have failed.

In the app, tap the source name shown for the zone and confirm the list of available sources loads correctly.

If a streaming service source is stuck, log out of that service inside the Loxone app and log back in, streaming credentials can expire silently.

Restart the source selection by switching to a local input first, then back to the streaming source you want.

Check that only one device is trying to control playback for that zone at the same time, a second phone or tablet controlling the same zone can cause it to jump sources.

Confirm every zone you're trying to group is online and responding individually before grouping them.

In the app, use the group or multi-room icon and select the zones again, a group can silently drop a zone if that zone lost network reachability when the group was formed.

Check that all zones you want to group are on the same Audioserver or on Audioservers that are properly linked together, cross-Audioserver grouping needs that link configured.

If grouping consistently fails for one specific zone, that zone's network connection to the Audioserver is the most likely cause.

Check the Audioserver's status LED if it's visible, similar to the Miniserver, no light usually means no power and a different color pattern means a network issue.

Confirm the Audioserver and your router haven't lost their network connection, an unplugged ethernet cable is the most common cause.

Restart the Miniserver from the app first, since the Audioserver often depends on the Miniserver for its connection status shown in the app.

If the Audioserver still doesn't show up after a Miniserver restart, it may need its own power cycle, which should be done by whoever installed it if you're not comfortable doing so.
