试一下在传输完成中断的地方修改传输长度 current_speaker->data_size = current_speaker->injection_size; read_length = current_speaker->packet_length; #if USB_AUDIO_CONFIG_PLAY_USE_FREQ_44_1_K if(current_speaker->node.audio_description->frequence == USB_AUDIO_CONFIG_FREQ_44_1_K) { if(current_speaker->injection_44_count < 9) { current_speaker->injection_44_count++; } else { current_speaker->injection_44_count = 0; current_speaker->data_size = current_speaker->alt_buf_half_size; read_length = current_speaker->packet_length_max_44_1; } } #endif /* USB_AUDIO_CONFIG_PLAY_USE_FREQ_44_1_K*/
