Abstract
A subscription-enabled audio device is provided, which comprises at least a speaker for providing an application audio output; a subscription verification module, allowing to determine a subscription state indicator; and an audio processor for controlling the speaker. To provide an enhanced audio device that is particularly suitable for Device-as-a-Service application, the audio processor is configured to query the subscription verification module to obtain the subscription state indicator and to provide a subscription state audio output in addition to said application audio output to the speaker in case the subscription state indicator corresponds to an unsubscribed state.
