Hi @hari22yuva,

This is already exposed as a capability. Capabilities.supportedContentTypes returns the list of content types supported by each audio sink instance.

The MW should:

1. Call IAudioSink.getCapabilities() to retrieve the Capabilities parcelable
2. Check supportedContentTypes[] to see which ContentType values are supported
3. Only call open(contentType, ...) with a content type that appears in that list

The sink does not need to support all content types — supportedContentTypes is the authoritative list. If the MW calls open() with an unsupported content type, the call should return null or throw EX_ILLEGAL_ARGUMENT.
