Switching between multiple earbud architectures

A method for switching between a first audio source and a second audio source by an audio rendering system comprising a primary wireless speaker and at least one secondary wireless speaker, wherein the method comprises:

• receiving a request to switch from receiving a first audio stream from the first audio source using a first audio topology to receiving a second audio stream from the second audio source using a second audio topology, wherein:
• said first audio topology corresponds to a first set of wireless links established between the primary wireless speaker, the secondary wireless speaker, and the first audio source,
• said second audio topology corresponds to a second set of wireless links between the primary wireless speaker, the secondary wireless speaker and the second audio source, and
• the second audio topology being different from the first audio topology;
• establishing the second set of wireless links of the second audio topology;
• starting to receive the second audio stream;
• maintaining the audio rendering system and the first audio source connected by a wireless link of the first set of wireless links, while receiving the second audio stream;
• receiving a request to switch back to receiving the first audio stream from the first audio source, wherein, after having received a switch back request, the first audio topology is retrieved from data stored in a memory of the audio rendering system or received from the first audio source via the wireless link maintained between said audio rendering system and said first audio source;
• if not all wireless links of the first set of wireless links have been maintained:
• establishing all the wireless links of the first set of wireless links of the first audio topology;
• starting to receive the first audio stream;
• and
• maintaining the audio rendering system and the second audio source connected by a wireless link of the second set of wireless links, while receiving the first audio stream.

• when the first audio topology is a forwarding audio topology and the second audio topology is a dual stream audio topology, and the first set of wireless links consists in a wireless link between the secondary wireless speaker and the primary wireless speaker and a wireless link between the first audio source and the primary wireless speaker:
• terminating the wireless link between the secondary wireless speaker and the primary wireless speaker;
• and
• changing a role parameter of the primary wireless speaker from master to slave.
