用JAVA sdk调用qwen-omni-turbo模型，没有返回语音流，modalities已设置

MultiModalConversationParam param = MultiModalConversationParam.builder()
.model("qwen-omni-turbo")

            .incrementalOutput(true)
            .modalities(List.of("text", "audio"))
            .audio(AudioParameters.builder().voice(AudioParameters.Voice.CHERRY).build())
            .message(userMessage)
            .build();

    conversation.streamCall(param, new ResultCallback<>() {
        @Override
        public void onEvent(MultiModalConversationResult multiModalConversationResult) {
            System.out.println(multiModalConversationResult.getOutput().getAudio() != null);
        }

        @Override
        public void onComplete() {

        }

        @Override
        public void onError(Exception e) {

        }
    });
